1.更新apt-get
apt-get update
2.安装keepalived
apt-get install keepalived
3. 安装成功后 keepalived 创建配置文件在 /etc/keepalived/keepalived.conf
vrrp_instance VI_1 { state MASTER #节点身份 master 会争抢虚拟ip interface ens33 #docker虚拟机网卡宿主机映射网络 virtual_router_id 51 mcast_src_ip 192.168.224.206 priority 100 #权重 advert_int 1 #心跳检测间隔 1s authentication { #心跳检测需要登录到keepalived,主从服务器验证，主备必须一致才行能正常通讯 auth_type PASS auth_pass 1111 } virtual_ipaddress { 192.168.224.208 #虚拟ip 往网卡中写入虚拟ip，docker内部可见 } track_script{ chk_nginx } }
4，启动keepalived 服务
service keepalived start
