1、安装

#查看是否可以YUM安装
yum list keepalived

#YUM安装
yum install -y keepalived

#设置开机自启动
systemctl enable keepalived

#启动
systemctl restart keepalived

2、主节点

tee /etc/keepalived/keepalived.conf <<-'EOF'
vrrp_instance VI_1 {
    state MASTER
    interface ens192
    virtual_router_id 51
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass passwrod
    }
 
    virtual_ipaddress {
        192.168.1.2/24
    }
}
EOF
systemctl restart keepalived

3、从节点(只是priority减少)

tee /etc/keepalived/keepalived.conf <<-'EOF'
vrrp_instance VI_1 {
    state BACKUP
    interface ens192
    virtual_router_id 51
    priority 99
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass passwrod
    }
 
    virtual_ipaddress {
        192.168.1.2/24
    }
}
EOF
systemctl restart keepalived

4、lvs负载
