210: and determining whether domain name information matched with the target domain name exists in the first cache space or not according to the target domain name.
The CDN cluster comprises a plurality of groups, each group comprises a plurality of machines, each machine serves as a service node, a plurality of service processes are operated or maintained on each service node, and the service processes need to acquire domain name configuration information. When domain name configuration information needs to be acquired, firstly, whether domain name information matched with a target domain name exists in a first cache space is determined according to the target domain name, since all domain name information of a redis configuration storage system is stored in the first cache space, whether the domain name information matched with the target domain name exists is determined according to the searching or matching of the target domain name in the first cache space, if so, the domain name is indicated to belong to a domain name maintained by the redis configuration storage system (hereinafter referred to as the system), and the step 220 is executed; if the domain name information matched with the target domain name does not exist in the first cache space, it indicates that the domain name does not belong to the domain name maintained by the present redis configuration storage system, and step 211 is executed.
Step 220: and when determining that the domain name information matched with the target domain name exists in the first cache space, determining whether the domain name configuration information matched with the target domain name exists in the second cache space according to the target domain name.
The second cache space is used for storing domain name configuration information with higher service node use frequency, for example, storing domain name configuration information with higher service node use frequency than a set value. When the target domain name is determined to belong to the domain name maintained by the system, determining whether domain name configuration information matched with the target domain name exists in the second cache space according to the target domain name, if so, directly calling the domain name configuration information, improving the efficiency of acquiring the domain name configuration information, and executing step 230; if the domain name configuration information matching the target domain name does not exist in the second cache space, it indicates that the target domain name is an unusual domain name, and the slave machine needs to obtain the relevant domain name configuration information, and then step 240 is executed.
Step 230: and when the domain name configuration information matched with the target domain name exists in the second cache space, returning the domain name configuration information to the corresponding process or service, and outputting returned success information.
And when the domain name configuration information matched with the target domain name exists in the second cache space, calling and returning by using an internal function interface, returning the domain name configuration information matched with the target domain name to the corresponding process or service, and outputting the returned success information.
In the information obtaining method provided in this embodiment, whether domain name information matched with a target domain name exists in a first cache space is determined according to the target domain name; when the first cache space is determined to have domain name information matched with the target domain name, determining whether domain name configuration information matched with the target domain name exists in a second cache space or not according to the target domain name, wherein the second cache space stores the domain name configuration information of which the service node use frequency is higher than a set value; and when the domain name configuration information matched with the target domain name exists in the second cache space, returning the domain name configuration information to the corresponding process or service, and outputting returned success information. According to the method, the safety of the domain name configuration information in the CDN system is guaranteed, when the target domain name is the domain name maintained by the system, the domain name configuration information is preferentially acquired in the cache space of the service node, and the efficiency of acquiring the domain name configuration information by the node is improved.
In some possible implementations, referring to fig. 4, in order to ensure timeliness of domain name information, when initializing a service node, the information obtaining method further includes:
step 201: and acquiring all domain name information corresponding to the group from the slave node corresponding to the group to which the service node belongs at preset time intervals.
And acquiring all domain name information from the slave node at preset time intervals. All the domain name information corresponding to the group refers to the domain name information of all the domain names maintained by the system.
Step 202: and updating all domain name information corresponding to the groups to the first cache space.
All domain name information corresponding to the group is updated to the first cache space so as to ensure that the domain name information of the latest version is always stored in the first cache space, and since the domain name information of all domain names maintained by the system is stored in the first cache space, even if the service node switches the group, when the relevant domain name configuration information needs to be obtained, the correct judgment can be made according to the target domain name (namely, whether the target domain name is available is determined), if the domain name information matched with the target domain name exists in the first cache space, the target domain name is available, and the domain name configuration information corresponding to the target domain name can be obtained from the second cache space or a slave node to which the group belongs.
In some possible implementations, referring to fig. 5, the information obtaining method further includes:
step 211: and outputting return failure information under the condition that the domain name information matched with the target domain name does not exist in the first cache space.
If the first cache space does not have the domain name information matched with the target domain name, the first cache space stores the domain name information of all the domain names maintained by the system in the latest version, so that if the first cache space does not have the related domain name information, the target domain name does not belong to the domain name maintained by the system, the domain name is unavailable, and the return failure information is output.
In some possible implementation manners, the second cache space is used to store domain name configuration information with a higher service node usage frequency, and when the domain name configuration information matched with the target domain name does not exist in the second cache space, it indicates that the domain name configuration information is domain name configuration information at the bottom of the service node usage frequency, and it is required to acquire related domain name configuration information from the slave, referring to fig. 6, the information acquisition method further includes:
step 240: and sending a configuration information acquisition request to a slave node corresponding to the group to which the service node belongs, wherein the configuration information acquisition request comprises a target domain name.
When the domain name information matched with the target domain name exists in the first cache space and the domain name configuration information matched with the target domain name does not exist in the second cache space, the target domain name is the maintained domain name of the group to which the service node belongs, but is not the common domain name of the service node.
Step 250: and acquiring domain name configuration information returned by the slave node.
And after receiving the configuration information acquisition request of the service node, the slave node returns the domain name configuration information matched with the target domain name to the service node, and the service node acquires the domain name configuration information returned by the slave node.
Step 260: and returning the domain name configuration information to the corresponding process or service, and storing the domain name configuration information to the second cache space.
And after the domain name configuration information returned by the slave node is acquired, returning the domain name configuration information matched with the target domain name to the corresponding process or service by using the internal function interface, and storing the domain name configuration information to a second cache space. In a possible implementation manner, the second cache space may be optimized by using a Least Recently Used (LRU) algorithm, and only the domain name configuration information with a high frequency of recent use is stored, so as to ensure high efficiency of the service node in acquiring the domain name configuration information.
Step 270: and updating the domain name configuration information to a third cache space, wherein the third cache space is used for storing all domain name configuration information of the group to which the service node belongs.
And after storing the domain name configuration information to the second cache space, updating the domain name configuration information to a third cache space, wherein the third cache space is used for storing all the domain name configuration information of the group to which the service node belongs. It can be understood that, the version of the domain name configuration information stored in the third cache space is older, the related domain name configuration information is stored in the third storage space, and when the latest domain name configuration information cannot be acquired from the slave node of the group to which the domain name configuration information belongs, the related domain name configuration information can be acquired from the third storage space.
In some possible implementations, when obtaining the domain name configuration information from the slave node fails, the method further includes:
step 241: and determining whether domain name configuration information matched with the target domain name exists in the third cache space or not according to the target domain name.
Failure to acquire domain name configuration information from the slave node corresponding to the belonging group may be caused by communication failure or by operation error of a worker. And if the latest domain name configuration information cannot be acquired from the slave node corresponding to the group, according to whether the target domain name has domain name configuration information matched with the target domain name in the third cache space.
And when the domain name configuration information matched with the target domain name exists in the third cache space, returning the domain name configuration information to the corresponding process or service, and outputting returned success information.
And outputting return failure information under the condition that the domain name configuration information matched with the target domain name does not exist in the third cache space.
It can be understood that, when normal communication with the slave node cannot be successfully established, the scheme provided in this embodiment may obtain the domain name configuration information of the "older version" from the third cache space to meet the user requirement, and after a connection is successfully established with the slave node and the updated domain name configuration information is obtained, the updated domain name configuration information is also updated to the third storage space, so that the updated domain name configuration information is used when communication cannot be successfully established with the slave node.
