Embodiment
For making the object, technical solutions and advantages of the present invention clearer, hereinafter in connection with accompanying drawing, embodiments of the invention are elaborated.It should be noted that, in the situation that not conflicting, the combination in any mutually of the feature in embodiment and embodiment in the application.
Fig. 1 is the flow chart of a kind of method of managing real server of the embodiment of the present invention, is applied in Linux Virtual Service Cluster system, as shown in the figure, comprises the following steps:
Step 11, monitor the existing state of the each real server in described Linux Virtual Service Cluster system;
Step 12, in the time judging that according to the existing state that monitors arbitrary real server breaks down or repairs, notify Linux virtual server by monitor message; In described monitor message, carry the mark of the real server breaking down or repair, and the shifting gears of state, described in shift gears as breaking down or repairing.
Fig. 2 is the flow chart of the method for the LVS management real server of the embodiment of the present invention, is applied in Linux Virtual Service Cluster system, as shown in the figure, comprises the following steps:
Step 21, receive the monitor message of state to stating the real server in LVS group system; In described monitor message, carry the mark of the real server breaking down or repair, and the shifting gears of state, described in shift gears as breaking down or repairing;
Step 22, according to described monitor message, corresponding real server is carried out to the corresponding processing of shifting gears of described state.
The follow-on lvs+keepalived group system of one that the embodiment of the present invention provides, increases by a monitoring equipment, as shown in Figure 3.In the present embodiment, the IP load-balancing technique of LVS is to realize by IPVS (IP Virtual Server, IP virtual server) module, and IPVS is the kernel software of LVS group system.It is upper that IPVS is arranged on Director Server (LIST SERVER), fictionalizes an IP address (VIP) on Director Server simultaneously, and user must pass through this virtual VIP address access services.First access request arrives load balance scheduler through VIP, then from Real Server (real server) list, chooses service node response user request by load balance scheduler according to the algorithm setting.IPVS realizes the mechanism of load balancing: be respectively NAT (Network Address Translation, network address translation), TUN (Tunneling, tunnel) and DR (Direct Routing, directly route), Keepalived module is here mainly as the realization of failover between the health status inspection of Real Server and LoadBalance (load balancing) main frame and BackUP (backup) main frame (unsuccessfully switching), monitoring equipment is known the state of Real Server at any time, when off-line occurs, after reaching the standard grade, notify LVS, by LVS, machine is kicked out of automatically or is increased to cluster the inside.
With a specific embodiment, method of the present invention is described in detail below.
Step 101, monitoring equipment is known the existing state of Real Server all in monitoring cluster by ping order;
Monitoring equipment can configure can log on Real Server by mutual trust app (application software)/database (database) is carried out to the operation such as stop (closing), start (unlatching).Can accomplish like this automation mechanized operation, not need to carry out manual operations.
Step 102, the Director Server of lvs receives the request that client sends, according to the strategy distribution request of configuration;
If NAT pattern, when request comes then, the IP address that the program of processing on Diretor server makes the destination address in data message (being virtual ip address) into concrete certain Real Server, port also makes the port of Real Server into, then message is issued to Real Server.Real Server handles after data, need to return to Diretor Server, and then Diretor server makes the source address in packet and source port into address and the port of VIP, finally data is sent.This scheme user's request and return and all will pass through Diretor Server, if overabundance of data, the pressure of Diretor Server is larger;
If TUN pattern, Real server is that after handling data, direct return data, to client, does not need the server through Diretor, and this greatly reduces the pressure of Diretor server;
If DR pattern,, by MAC (Media Access Control, the media access control) address of overwrite request message, request is sent to Real Server, and response is directly returned to client by Real Server, remove the IP tunnel expense in VS/TUN from.This mode is that three kinds of load dispatch mechanism performances are the highest best, but necessarily requires Director Server and Real Server to have a network interface card to be connected on the Same Physical network segment.
Step 103, keepalived module detects the state of Real Server, if there is a Real Server to crash, or work breaks down, Keepalived will detect, and out of order Real Server will be switched to the Real Server of backup; After Real Server is working properly, Keepalived module also can join the Real Server of reparation in server cluster, and these work all complete automatically, do not need artificial interference, the Real Server that just repairs fault that need to manually do.
Step 104, monitoring equipment are monitored all Real Server, and after having Real Server that down (deadlock) occurs or repairing, notice LVS kicks out of Real Server or adds in group system.
Step 105, LVS receive after notice, the IP address of the Real Server breaking down is deleted from database, or the IP address of the Real Server having repaired is joined in database.
