Description
Technical Field
The invention relates to the technical field of cloud computing, in particular to a method, a device, equipment and a readable medium for clearing invalid virtual IP.
Background
Cloud computing technology has developed as a trend in the IT industry today. The cloud computing can build physical resources through a professional network company, and a user can obtain cloud services through an internet access mode. Just like a kind of negotiable goods, the biggest characteristic is transmission through the internet. Any cloud environment should guarantee connectivity and high availability of services, whether in a system environment or a production environment.
Therefore, in the system deployment process, the requirements on the safety and the reliability of the server are high, and in the case of server failure, the operation needs to be recovered in the shortest possible time. And whether the function can be realized is a main index of whether the system achieves high availability.
Among the many schemes that are highly available, keepalived + Haproxy is one implementation that is often employed. The keepalived is used for detecting the state of the server, if one server is down or other faults occur to cause that the current server is unavailable, the keepalived can detect and remove the fault server from the system, meanwhile, the standby server is used for replacing the work of the server, when the server works normally, the keepalived automatically adds the server into a server group, and all the work is automatically completed without manual interference. The keepalived software mainly realizes the high available function through the VRRP protocol. VRRP (Virtual Router redundancy protocol), which aims to solve the problem of single point failure of static routing, can ensure that the whole network can operate uninterruptedly when an individual node is down. However, when keepalive and Haproxy are deployed by containerization installation, when a docker container service or a keepalive container is restarted, the VIP of the local host cannot be normally released occasionally, and the situation that two identical VIPs exist in the same cluster environment occurs, but one of the VIPs cannot provide service at this time, so that normal use of the system is affected.

In this embodiment, Docker is an open source application container engine; keepalived is high-availability solution software that implements high-availability functionality via the VRRP protocol; HAProxy is a piece of proxy software that offers high availability, load balancing, and TCP (layer four) and HTTP (layer seven) based applications; VRRP (Virtual router redundancy protocol), which aims to solve the problem of single point failure of static routing, can ensure that the whole network can operate uninterruptedly when an individual node is down.
Take the following cluster deployment as an example: two Hasproxy agents are added in front of three application servers, then VIP is used for carrying out access requests to services, the requests of users are sent to the proxy servers firstly, and then are distributed to specific application servers according to a load balancing strategy. Once the Haproxy on the first node fails, the second node takes over the proxy service to ensure the availability of the application service, and both Haproxy and keepalived are deployed in a docker containerization mode. To ensure high availability of the clustered environment, the VIP in the clustered environment is guaranteed to be active. That is, only one VIP can exist in the cluster environment and this VIP is active. Therefore, real-time monitoring of VIPs in a cluster network environment needs to be achieved, and invalid VIPs which are not released in time and are generated due to docker service restart or keepalived container restart are removed in time.
