1.安装yum install -y keepalived2.备份cd /etc/keepalived
cp keepalived.conf keepalived.conf.back
1.创建配置文件echo "! Configuration File for keepalived

}
vrrp_instance VI_1 {
#主机设置为MASTER
state MASTER

#主从id要一样
virtual_router_id 51
#主机权重高于从机
priority 80

auth_pass 1111
}
virtual_ipaddress {
#虚拟的ip,多个ip换行写即可
