Description

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for configuring a virtual machine and a related device.

Background

In a current distributed NAS (Network Attached Storage) Storage, in order to ensure reliability of data in the distributed NAS Storage, redundancy configuration is usually performed on the stored data, and a redundancy configuration method in the prior art is based on a fixed rule, for example, a fixed redundancy mode and a redundancy ratio value are set for a certain directory or a certain file system on a Storage system.

For a virtual machine working disk created in a virtual machine server, different users have different purposes and different stored data, so that the requirements of different users on redundancy protection are different. However, in the prior art, the distributed NAS storage can only set a fixed redundancy protection mode for the virtual machine file, and cannot be distinguished according to the user type. For example, when the financial system uses the virtual machines, they may require the virtual machine working disks of their own to have a higher redundancy ratio value, and for the ordinary users, the lower redundancy ratio value may be adopted, but the existing redundancy ratio method cannot configure different redundancy ratio values for the virtual machine working disks used by the financial system and the ordinary users, respectively.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a schematic flowchart of a method for configuring a virtual machine according to an embodiment of the present invention is shown, where the method includes:

s101, when sharing connection is carried out with a virtual machine server, receiving an authentication request which is sent by the virtual machine server and carries user information, and forwarding the authentication request to an authentication server;

specifically, before the storage server is connected to the virtual machine server in a shared manner, the virtual machine server installs the virtual machine of the user, and then enters the virtual machine to map the virtual machine working disk to a certain directory of the storage server through the shared manner, and at this time, the user can use the virtual machine through the user equipment. Because the virtual machine working disk is mapped to the storage server through sharing, when the virtual machine working disk is loaded, the virtual machine server initiates a sharing connection to the storage server and sends an authentication request, so that the storage server can receive the authentication request which is sent by the virtual machine server and carries user information, and forwards the authentication request to the authentication server. The storage server may be a distributed NAS storage server, and the user information may include a user account, a password, a network address of the virtual machine server, and the like.

S102, when the authentication server passes the authentication of the user information, receiving preset redundant configuration information corresponding to the user information, which is sent by the authentication server;

specifically, after the storage server forwards the authentication request to the authentication server, the storage server may detect whether the authentication server passes authentication of the user information, or the authentication server may send an authentication result to the storage server, and when the authentication server passes authentication of the user information, the storage server may receive preset redundant configuration information corresponding to the user information, which is sent by the authentication server. The redundancy configuration information is preset redundancy configuration information for a user corresponding to each user information in the authentication server by an IT administrator, and the redundancy configuration information comprises a redundancy mode and a redundancy ratio value.

S103, when a file creating request initiated by the virtual machine server is received, performing redundancy configuration on the created file according to the redundancy configuration information;

specifically, after the authentication server authenticates the user information, the user may initiate a file creation request through the virtual machine, that is, the storage server may receive the file creation request initiated by the virtual machine server, at this time, the storage server may perform redundancy configuration on the created file according to the obtained redundancy configuration information corresponding to the user information, that is, perform redundancy configuration on the created file by using a corresponding redundancy mode and a corresponding redundancy ratio value, so as to implement reliability protection on the file in the virtual machine working disk of each user.

According to the embodiment of the invention, the redundancy configuration information corresponding to the user information and sent by the authentication server is received, and the file created by the virtual machine corresponding to the user information can be subjected to redundancy configuration according to the redundancy configuration information, so that the distributed NAS storage can configure different redundancy ratios for the virtual machine working disks of different users to meet the redundancy ratio required by each user, and meanwhile, the virtual machine working disks can share and map to the storage server, so that the virtual machine server only needs to be provided with the virtual machine image file for installing the operating system, and the migration and cloning of the virtual machine are facilitated.

Referring to fig. 2 again, a schematic flow chart of another method for configuring a virtual machine according to an embodiment of the present invention is shown, where the method includes:

s201, presetting a shared directory corresponding to the virtual machine server;

and the shared directory and the virtual machine working disk in the virtual machine server are in a shared mapping relationship. Before the storage server is connected with the virtual machine server in a sharing mode, the storage server can preset a sharing directory corresponding to the virtual machine server, meanwhile, the virtual machine server is installed with a virtual machine of a user, then the virtual machine server enters the virtual machine to map a virtual machine working disk to the preset sharing directory in the storage server through sharing, and at the moment, the user can use the virtual machine through user equipment.

S202, when sharing connection is carried out with a virtual machine server, receiving an authentication request which is sent by the virtual machine server and carries user information, and detecting a storage protocol used by the authentication request sent by the virtual machine server;

since the virtual machine working disk is mapped to the storage server through sharing, when the virtual machine working disk is loaded, the virtual machine server initiates a sharing connection to the storage server and sends an authentication request, so that the storage server can receive the authentication request carrying user information sent by the virtual machine server, and at the moment, the storage server can also detect a storage protocol used by the authentication request sent by the virtual machine server.

S203, forwarding the authentication request to an authentication server corresponding to the storage protocol through the detected storage protocol;

the storage server may forward the authentication request to an authentication server corresponding to the storage protocol through the detected storage protocol. Further, when detecting that the used storage protocol is a server information block (SMB) protocol, forwarding the authentication request to an Active Directory (AD) server through the SMB protocol, and in a subsequent process, the storage server interacts with the authentication server and the virtual machine server by using the SMB protocol; or, when it is detected that the used storage protocol is a Network File System NFS (Network File System) protocol, the authentication request is forwarded to a Lightweight Directory access protocol LDAP (Lightweight Directory access protocol) server through the Network File System NFS protocol, and in a subsequent process, the storage server interacts with the authentication server and the virtual machine server by using the NFS protocol.

S204, when the authentication server passes the authentication of the user information, receiving preset redundant configuration information which is sent by the authentication server and corresponds to the user information;

S205, receiving a preset Quota quote value corresponding to the user equipment sent by the authentication server;

when the storage server detects that the authentication server passes the authentication of the user information, the storage server may further receive a preset Quota quote value corresponding to the user equipment, which is sent by the authentication server, where the Quota quote value is a capacity value of a working disk of a virtual machine, and the Quota quote value is also a Quota quote value preset by an IT administrator for a user corresponding to each user information in the authentication server.

S206, sending the Quota quote value to the virtual machine server, so that the virtual machine server allocates the capacity value of the virtual machine working disk according to the Quota quote value;

after the storage server obtains the Quota quote value, the storage server may send the Quota quote value to the virtual machine server, so that the virtual machine server allocates a capacity value of a virtual machine working disk according to the Quota quote value.

S207, when a file creating request initiated by the virtual machine server is received, extracting a redundancy mode and a redundancy ratio value from the redundancy configuration information;

after the capacity value of the virtual machine working disk is allocated by the virtual machine server, a user can initiate a file creation request through the virtual machine server. When the storage server receives a file creation request initiated by the virtual machine server, the storage server may extract a redundancy mode and a redundancy ratio value from the redundancy configuration information.

S208, sending the redundancy mode, the redundancy ratio value and the created file to a local distributed file system, and performing redundancy configuration on the created file according to the redundancy mode and the redundancy ratio value by the distributed file system;

after the storage server extracts the redundancy mode and the redundancy ratio, the storage server sends the redundancy mode, the redundancy ratio and the created file to a local distributed file system, and the distributed file system performs redundancy configuration on the created file according to the redundancy mode and the redundancy ratio, for example, if the extracted redundancy mode is erase Code and the redundancy ratio is 9:3, the distributed file system splits the created file data into 12 parts, where 9 parts are valid data and 3 parts are check data.

According to the embodiment of the invention, the redundant configuration information and the Quota Quota value which are sent by the authentication server and correspond to the user information are received, the file which is created by the virtual machine corresponding to the user information can be configured redundantly according to the redundant configuration information, the capacity value of the corresponding virtual machine working disk is controlled to be distributed to the virtual machine server through the Quota Quota value, so that the distributed NAS storage can configure different redundant proportions for the virtual machine working disks of different users, the virtual machine working disks with different capacity values are distributed to different users, the redundant proportions and the Quota Quota value required by each user are met, and meanwhile, the virtual machine working disks can be shared and mapped to the storage server, so that the virtual machine server only needs to be provided with the virtual machine image file provided with the operating system, and the migration and cloning of the virtual machine are facilitated.

Further, referring to fig. 3 again, a flowchart of one method for capacity expansion according to an embodiment of the present invention is shown, where the method includes:

specifically, the step S301 may be executed after S102 in the embodiment corresponding to fig. 1 or after S204 in the embodiment corresponding to fig. 2, that is, after the storage server detects that the authentication server passes authentication of the user information, the storage server may detect in real time whether the total capacity of the created file is greater than the Quota value, and if the total capacity of the created file is less than the Quota value, the storage server may continue to receive a file creation request initiated by the virtual machine server and perform redundant configuration on the created file according to the redundant configuration information; if the Quota quantum value is detected to be larger than the Quota quantum value, which indicates that the capacity of the virtual machine working disk is full, the step S302 is executed.

S302, when detecting that the total capacity of the created file is larger than the Quota Quota value, sending error prompt information to user equipment using the virtual machine server, so that the user equipment sends a capacity expansion request to the authentication server to update the Quota Quota value;

when detecting that the total capacity of the created file is larger than the Quota quote value, sending error prompt information to user equipment using the virtual machine server to notify a user that the capacity of the virtual machine working disk is full, and at this time, the user equipment can send a capacity expansion request to the authentication server to update the Quota quote value.

S303, when detecting that the virtual machine server reloads the virtual machine working disk, receiving an updated Quota quote value sent by the authentication server, and sending the updated Quota quote value to the virtual machine server, so that the virtual machine server redistributes the capacity value of the virtual machine working disk according to the updated Quota quote value;

specifically, when the storage server detects that the virtual machine server reloads the virtual machine working disk, the virtual machine server initiates a sharing connection and an authentication request again, after the authentication server passes authentication on the user information again, the storage server may receive the redundant configuration information and the updated Quota value sent by the authentication server, and the storage server may send the updated Quota value to the virtual machine server, so that the virtual machine server reallocates the capacity value of the virtual machine working disk according to the updated Quota value, so that the capacity of the virtual machine working disk of the user can be increased, and the user can continue to use the virtual machine.

According to the embodiment of the invention, the Quota Quota value is updated, so that the capacity value of the virtual machine working disk can be redistributed according to the updated Quota Quota value when the virtual machine server reloads the virtual machine working disk, the capacity expansion of the virtual machine working disk can be simply realized, and the problem of difficulty in capacity expansion of the virtual machine working disk is solved.

specifically, when the authentication server passes authentication of the user information, the authentication server may send preset redundant configuration information corresponding to the user information to the storage server, so that the storage server performs redundant configuration on a file created by the virtual machine server according to the redundant configuration information. The storage server may receive a file creation request sent by the virtual machine server, and at this time, the storage server may perform redundant configuration on the file created by the virtual machine server according to the redundant configuration information acquired from the authentication server.

According to the embodiment of the invention, by receiving the redundancy configuration information corresponding to the user information sent by the authentication server, the storage server can perform redundancy configuration on the file created by the virtual machine corresponding to the user information according to the redundancy configuration information, so that the distributed NAS storage can configure different redundancy ratios for the working disks of the virtual machines of different users, and the redundancy ratios required by the users can be met.

Referring to fig. 6, a schematic structural diagram of a system configured by a virtual machine according to an embodiment of the present invention is shown, where the system includes: a storage server 1, an authentication server 2, and a virtual machine server 3;

the storage server 1 is configured to receive an authentication request carrying user information sent by a virtual machine server 3 and forward the authentication request to an authentication server 2 when sharing connection is performed with the virtual machine server 3, receive preset redundant configuration information corresponding to the user information sent by the authentication server 2 when the authentication server 2 passes authentication of the user information, and perform redundant configuration on a created file according to the redundant configuration information when receiving a file creation request initiated by the virtual machine server 3;

the authentication server 2 is configured to receive an authentication request forwarded by the storage server 1, where the authentication request is an authentication request carrying user information and sent by the virtual machine server 3, authenticate the user information according to the authentication request, and send preset redundant configuration information corresponding to the user information to the storage server 1 when the user information passes authentication;

the virtual machine server 3 is configured to send an authentication request carrying user information to the storage server 1 when sharing connection is performed with the storage server 1, and is further configured to send a file creation request to the storage server 1.

Specifically, before the storage server 1 and the virtual machine server 3 are connected in a shared manner, the virtual machine server 3 first installs a virtual machine of a user, and then enters the virtual machine to map a virtual machine working disk to a certain directory of the storage server 1 through sharing, and at this time, the user can use the virtual machine through user equipment. Since the virtual machine working disk is mapped to the storage server 1 by sharing, when the virtual machine working disk is loaded, the virtual machine server 3 initiates a sharing connection to the storage server 1 and sends an authentication request, so that the storage server 1 can receive the authentication request carrying the user information sent by the virtual machine server 3 and forward the authentication request to the authentication server 2. The storage server 1 may be a distributed NAS storage server 1, and the user information may include a user account, a password, a network address of the virtual machine server 3, and the like.

After the storage server 1 forwards the authentication request to the authentication server 2, the storage server 1 may detect whether the authentication server 2 passes the authentication of the user information, or the authentication server 2 may send an authentication result to the storage server 1, and when the authentication server 2 passes the authentication of the user information, the storage server 1 may receive the preset redundant configuration information corresponding to the user information sent by the authentication server 2. The redundant configuration information is preset by an IT administrator in the authentication server 2 for each user corresponding to the user information, and includes a redundant mode and a redundant ratio.

After the authentication server 2 authenticates the user information, a user may initiate a file creation request through a virtual machine, that is, the storage server 1 may receive the file creation request initiated by the virtual machine server 3, at this time, the storage server 1 may perform redundancy configuration on the created file according to the obtained redundancy configuration information corresponding to the user information, that is, perform redundancy configuration on the created file by using a corresponding redundancy mode and a corresponding redundancy ratio value, so as to implement reliability protection on the file in the virtual machine working disk of each user.

The storage server 1 is specifically configured to extract a redundancy mode and a redundancy ratio value from the redundancy configuration information when receiving a file creation request initiated by the virtual machine server 3;

The storage server 1 is further configured to receive a preset Quota quote value corresponding to the user equipment and sent by the authentication server 2, and send the Quota quote value to the virtual machine server 3;

the virtual machine server 3 is further configured to receive the Quota quote value sent by the storage server 1, and allocate a capacity value of a virtual machine working disk according to the Quota quote value.

In addition, the storage server 1 is further configured to detect whether the total capacity of the created file is greater than the Quota value, and when detecting that the total capacity of the created file is greater than the Quota value, send error prompt information to the user equipment using the virtual machine server 3, so that the user equipment sends a capacity expansion request to the authentication server 2 to update the Quota value, and when detecting that the virtual machine server 3 reloads a virtual machine working disk, receive the updated Quota value sent by the authentication server 2, and send the updated Quota value to the virtual machine server 3;

the authentication server 2 is further configured to receive a capacity expansion request sent by the user equipment using the virtual machine server 3, update the Quota quote value according to the capacity expansion request, and send the updated Quota quote value to the storage server 1 when detecting that the virtual machine server 3 reloads the virtual machine working disk;

the virtual machine server 3 is further configured to receive the updated Quota quote value sent by the storage server 1, and redistribute the capacity value of the virtual machine working disk according to the updated Quota quote value.

Specifically, after the storage server 1 detects that the authentication server 2 passes the authentication of the user information, the storage server 1 may detect in real time whether the total volume of the created file is greater than the Quota value, and if the total volume of the created file is smaller than the Quota value, the storage server 1 may continue to receive a file creation request initiated by the virtual machine server 3 and perform redundancy configuration on the created file according to the redundancy configuration information; and if the Quota Quota value is detected to be larger than the Quota Quota value, indicating that the capacity of the working disk of the virtual machine is full.

When detecting that the total capacity of the created file is greater than the Quota quote value, sending an error prompt message to the user equipment using the virtual machine server 3 to notify the user that the capacity of the virtual machine working disk is full, and at this time, the user equipment may send a capacity expansion request to the authentication server 2 to update the Quota quote value.

When the storage server 1 detects that the virtual machine server 3 reloads the virtual machine working disk, the virtual machine server 3 initiates a sharing connection and an authentication request again, after the authentication server 2 passes authentication on the user information again, the storage server 1 can receive the redundant configuration information and the updated Quota value sent by the authentication server 2, and the storage server 1 can send the updated Quota value to the virtual machine server 3, so that the virtual machine server 3 reallocates the capacity value of the virtual machine working disk according to the updated Quota value, the capacity of the virtual machine working disk of the user can be increased, and the user can continue to use the virtual machine.

The authentication server 2 is further configured to receive a capacity expansion request sent by the user equipment using the virtual machine server 3, and update the Quota quote value according to the capacity expansion request;

when it is detected that the virtual machine server 3 reloads the virtual machine working disk, sending an updated Quota quote value to the storage server 1, so that the storage server 1 sends the updated Quota quote value to the virtual machine server 3 to reallocate the capacity value of the virtual machine working disk corresponding to the updated Quota quote value.

Specifically, when the capacity of the virtual machine working disk is full, the user equipment using the virtual machine server 3 will initiate a capacity expansion request, and at this time, the authentication server 2 may receive the capacity expansion request sent by the user equipment using the virtual machine server 3, and update the Quota quote value according to the capacity expansion request.

When the authentication server 2 detects that the virtual machine server 3 reloads the virtual machine working disk through the storage server 1, the virtual machine server 3 re-initiates a sharing connection and an authentication request, and after the authentication server 2 passes authentication on the user information again, the authentication server 2 can send an updated Quota quote value to the storage server 1, so that the storage server 1 sends the updated Quota quote value to the virtual machine server 3 to re-allocate the capacity value of the virtual machine working disk corresponding to the updated Quota quote value; meanwhile, the authentication server 2 may also send the redundant configuration information to the storage server 1 again, so that the storage server 1 may still perform redundant configuration on the file created by the virtual machine server 3 according to the redundant configuration information.

The storage server 1 is specifically configured to receive an authentication request carrying user information sent by a virtual machine server 3 when sharing connection is performed with the virtual machine server 3, and detect a storage protocol used by the authentication request sent by the virtual machine server 3;

the authentication request is forwarded to the authentication server 2 corresponding to the storage protocol by the detected storage protocol.

Specifically, since the virtual machine working disk is mapped to the storage server 1 by sharing, when the virtual machine working disk is loaded, the virtual machine server 3 initiates a sharing connection to the storage server 1 and sends an authentication request, so that the storage server 1 can receive an authentication request carrying user information sent by the virtual machine server 3, and at this time, the storage server 1 can also detect a storage protocol used by the authentication request sent by the virtual machine server 3.

The storage server 1 may forward the authentication request to an authentication server 2 corresponding to the storage protocol through the detected storage protocol. Further, when detecting that the used storage protocol is a server information block (SMB) protocol, forwarding the authentication request to an Active Directory (AD) server through the SMB protocol, and in a subsequent process, the storage server 1 interacts with the authentication server 2 and the virtual machine server 3 by using the SMB protocol; or, when detecting that the used storage protocol is a network file system NFS protocol, forwarding the authentication request to a lightweight directory access protocol LDAP server through the network file system NFS protocol, and in a subsequent flow, the storage server 1 interacts with the authentication server 2 and the virtual machine server 3 using the NFS protocol.

The virtual machine working disk in the virtual machine server 3 is mapped to the storage server 1 by sharing, so that the virtual machine server 3 only needs to have a virtual machine image file for installing an operating system.

By receiving the redundant configuration information and the Quota quote value which are sent by the authentication server 2 and correspond to the user information, the storage server 1 can determine, according to the redundant configuration information, the file created by the virtual machine corresponding to the user information is configured redundantly, the virtual machine server 3 is controlled to distribute the capacity value of the corresponding virtual machine working disk through the Quota quote value, so that the distributed NAS storage can configure different redundancy ratios for the virtual machine working disks of different users, and allocates virtual machine working disks with different capacity values for different users to meet the redundancy ratio and Quota Quota value required by each user, meanwhile, by updating the Quota quote value, when the virtual machine server 3 reloads the virtual machine working disk, the capacity value of the virtual machine working disk can be redistributed according to the updated Quota quote value, so that the capacity expansion of the virtual machine working disk can be simply realized.
