在两台机器上执行yum install -y keepalived
128机器之前已经安装了nginx，所以只要在129机器上安装nginx yum install -y nginx
[root@lizhipenglinux01 ~]# ls /etc/keepalived/keepalived.conf
/etc/keepalived/keepalived.conf
[root@lizhipenglinux01 ~]# cat !$
把原始的文件清空掉
[root@lizhipenglinux01 ~]# > /etc/keepalived/keepalived.conf
nginx与keepalived都没有问题
nginx服务停止后，自动启动了
/var/log/messages 存放keepalived日志
检查防火墙
检查从，发现有防火墙，systemctl stop firewalld
关闭主上的keepalived，发现主上192.168.5.100没有了，而从上有192.168.5.100
访问192.168.5.100，是从的默认页面
再开启主的keepalived服务，主上有192.168.5.100，而从上没有了
访问192.168.5.100，主的默认页面
