nginx集群的搭建

1.建立两个虚拟机：  192.168.67.10（Master） 192.168.67.129(BACKUP)

然后需要在每一个nginx服务器上安装keepalived

yum install keepalived  安装keepalived   yum:联网安装
rpm -q -a keepalived  检查是否安装keepalived  ps -ef | grep keepalived

默认安装路径: /etc/keepalived

开启所有的nignx 和 keepalived

./nginx
systemctl start keepalived.service

然后测试访问 ：

让主节点宕机再访问：

./nginx -s stop
systemctl stop keepalived.service
