the step 5 comprises the following steps: the method comprises the steps that two application servers are used as load balancing servers, one of a main machine and a standby machine is used for realizing route calculation in load balancing through keepalive and nginx, and keepalive and nginx are deployed on the main machine and the standby machine of the load balancing servers respectively;
the keep-alive on the two load balancing servers is responsible for providing a virtual ip to the outside and is configured into a main-standby mode, and a client or other external systems access through the virtual ip, so that the state monitoring of the nginx is realized; when the main load balancing server fails, the standby load balancing server takes over external service;
the two load balancing servers are configured into a main and standby mode in the same manner as the configuration mode of the nginx; intercepting all the accessed url, and defaulting to proxy the accessed url to a main server of a CS resource system server, a BS resource system server and an interface server, wherein when the main servers of the CS resource system server, the BS resource system server and the interface server are in failure, the server is proxy to a standby server of the CS resource system server, the BS resource system server and the interface server through a nginx;
after the existing database, all functions and data of the management and control system are operated to the dispatching cloud platform through the power grid backbone communication network, all hardware of the original system is cancelled, and resources are provided by the dispatching cloud platform instead, including virtual machines, storage and network resources.
6. The cloud platform-based power grid communication resource virtual machine migration method of claim 5, wherein the method comprises the steps of: step 5, installing keepalive and nginx in the load balancing server, and carrying out relevant configuration; the nginx configures the physical IP, port, access url of each application and sets the relation of the main application and the standby application; the keepalive configures an external virtual ip, nginx validity check script.
