Docker 搭建pxc集群 + haproxy + keepalived 高可用（三）

本次搭建 keepalived

1、在Docker 搭建pxc集群 + haproxy + keepalived 高可用（二）基础上我们继续进入h1容器

docker exec -it h1 bash

2、更新apt-get

apt-get update

3、安装keepalived

apt-get install keepalived

4、安装vim

apt-get install vim

5、新建keepalived.conf配置文件

vim /etc/keepalived/keepalived.conf

配置文件内容如下:

vrrp_instance  VI_1 {
    state  MASTER
    interface  eth0
    virtual_router_id  51
    priority  100
    advert_int  1
    authentication {
        auth_type  PASS
        auth_pass  123456
    }
    virtual_ipaddress {
        172.18.0.201
    }
}

6、启动keepalived

service keepalived start

7、然后在宿主机上ping 172.18.0.201 看看是否能ping通。

说明搭建成功
