本文详细记录了在CentOS7.5环境下，如何部署Nginx+keepalived集群，包括环境准备、Nginx安装、keepalived配置、启动和监控，以及解决常见问题的步骤。通过配置，实现了Nginx的负载均衡和高可用性。

环境

系统环境为centos7.5Everything版
本部署方案仅适用于centos7.5版本，因为该版本内置多种依赖及软件，所以后续部署步骤相对简化。
nginx：http://nginx.org/en/download.html 版本：nginx-1.18.0

解压nginx文件夹

tar -zxvf nginx-1.18.0.tar.gz

安装 pcre-devel-8.32

rpm -ivh pcre-devel-8.32-17.el7.x86_64.rpm

安装zlib

rpm -ivh zlib-1.2.7-17.el7.x86_64.rpm
rpm -ivh zlib-devel-1.2.7-17.el7.x86_64.rpm

安装nginx

./configure && make && make install

启动keepalived

[root@localhost ~]# systemctl start keepalived //启动keepalived
[root@localhost ~]# systemctl enable keepalived //加入开机启动keepalived
[root@localhost ~]# systemctl restart keepalived //重新启动keepalived
[root@localhost ~]# systemctl status keepalived //查看keepalived状态
设置开机自启动
　　chkconfig keepalived on
　　
更改keepalived配置文件

keepalived.conf配置文件说明

keepalived的配置主要是全局配置和VRRP配置，其他默认的可以不要
