18.1 集群介绍 18.2 keepalived介绍 18.3/18.4/18.5 用keepalived配置高可用集群

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
