How to achieve keepalived+nginx high availability
Article Introduction:1. Introduction to keepalived Keepalived was originally designed for LVS load balancing software to manage and monitor the status of each service node in the LVS cluster system. Later, the vrrp function to achieve high availability was added. In addition to managing LVS software, keepalived can also support high-availability solutions for other services. keepalived implements high availability function through vrrp protocol. vrrp (virtualrouterredundancyprotocol) virtual routing redundancy protocol. The purpose of vrrp is to solve the single point of failure problem of static routing. It can ensure that when individual nodes go down, the entire network can run uninterrupted.
