Description
Technical Field
The present application relates to the field of computer technologies, and in particular, to a method, a system, and a computer device for node switching.
Background
With the rapid development of the internet technology, the public has higher requirements on the security index of the internet environment, and the public relies on a cloud security protection system. The cloud security protection system is used for researching and realizing security protection services required by the cloud platform system. The cloud security protection system provides flexible and diverse policy mechanisms, and the protection system policy mechanisms comprise security application interfaces, middleware and the like to realize integration and practicability of various current cloud service platforms. A safe and effective modular cloud safety protection system is established, can be applied to any cloud platform, provides enough safety guarantee for the cloud platform serving as a cloud service foundation, and lays a solid theoretical and technical foundation for further popularization of a cloud computing technology. The cloud security protection system comprises user and account management, and provides comprehensive security capabilities such as cloud acceleration, DNS protection, total-station mirroring, big data security analysis and intelligent security management for user websites mostly, realizes visible value for clients, reduces website data leakage and webpage tampering risks, improves website link reliability, encrypts sensitive information, provides retrieval and query technology based on ciphertext, and has the advantages of reliability and fault tolerance of a storage system, data security and privacy protection, software behavior discrimination, cloud security standard test programs and the like.
At present, the number of access times of a security protection system is rapidly increased, the pressure on a server is increased, a website accessed by a client bears the service of the client, and if the service of the client is interrupted due to the failure of the server of the security protection system, loss which is difficult to estimate is caused, so in order to deal with the situation, a Virtual Router Redundancy Protocol (VRRP) in a local area network is adopted to improve the high availability of a cluster, and the Protocol is used for dealing with the situation that a node is unavailable due to machine downtime.
VRRP is a selection protocol that can dynamically allocate the responsibility of a virtual router to one of the VRRP routers on the local area network. The VRRP router that controls the virtual router IP addresses is called the master router, which is responsible for forwarding packets to these virtual IP addresses. This selection process provides a dynamic failover mechanism once the primary router is unavailable, which allows the IP address of the virtual router to act as the default first hop router for the end host. Is a LAN access equipment share protocol. All hosts in a local area network are provided with default gateways, so that messages sent by the hosts and having destination addresses which are not in the network segment are sent to the three-layer switch through the default gateways, and communication between the hosts and an external network is realized. VRRP is also a route fault tolerance protocol, which may also be called a backup routing protocol. All hosts in a local area network are provided with default routes, and when the destination address sent by the host in the network is not in the network segment, the message is sent to an external router through the default route, so that the communication between the host and the external network is realized. When the default router port is closed, the internal host cannot communicate with the external host, and if the router sets the VRRP, the virtual router enables the backup router, thereby realizing the full-network communication.
A World Wide Web (Web for short) server cluster system is a cluster system composed of a group of servers running the same application at the same time, and looks like a server to the outside. In order to balance the load of the cluster server and achieve the purpose of optimizing the system performance, the WEB cluster server distributes a plurality of access requests to different nodes in the system for processing. Thus, higher efficiency and stability are achieved, which are characteristics that WEB-based enterprise applications must possess.
The high-availability cluster is the design key point of a distributed system architecture, and is characterized in that when a certain node or a server fails, another node can automatically and immediately provide services to the outside, so that resources on the failed node can be transferred to the other node, and the other node can provide the services to the outside. The high-availability cluster can switch resources and services when a single point fails, so that the server service is not interrupted. When the system equipment assumes that the system is always able to provide a service, the availability of the system is 100%, for example. If the system has 1 time unit to provide no service per 100 time units of operation, the availability of the system is 99%. The high availability target is 4 9, i.e. 99.99%, which means that the annual down time of the system is 8.76 hours, reaching a very high level of high availability.
At present, no effective solution is provided for the problem of false death caused by high node load in the related technology.

and adjusting the first weight value according to the number of front-end service processes and the number of back-end service processes of the main node, wherein the first weight value is inversely proportional to the return values of the number of front-end service processes and the number of back-end service processes of the main node.
8. The method of node switching according to claim 1,
the adjusting the first weight value according to the return value of the hardware running state of the node and the return value of the service process comprises:
and adjusting the first weight value according to the return value, wherein the return value is obtained by the main node according to the load return value of the CPU of the main node, the return value of the memory usage of the server, the consumption condition of the hard disk, the return value of the residual space of the hard disk, the number of front-end service processes and the number of rear-end service processes.
9. A node switching system is characterized by comprising a main node, a first slave node and a second slave node, wherein the main node is configured to be a first weight value, the first slave node is set to be a second weight value, the second weight value is smaller than the first weight value, and the first weight value and the second weight value are both larger than a preset threshold value;
and adjusting the first weight value according to the return value of the hardware running state of the main node and the return value of the service process, and switching the main node to the second slave node after the first weight value is smaller than the preset threshold value.
10. A computer device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, characterized in that the steps of the method of any of claims 1 to 8 are implemented when the computer program is executed by the processor.
