Posted 2021-01-11 zhengchuzhou

一、在haproxy容器安装Keepalived

1、进入haproxy容器: docker exec -it h1 bash

2、apt-get update（因为haproxy容器为Ubuntu）

3、apt-get install -y keepalived

二、配置：

1、安装vim编辑器：apt-get install -y vim

2、编辑keepalived.conf文件：vim /etc/keepalived/keepalived.conf

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
    }
}

3、开启keepalived：service keepalived start

 

4、检测：在宿主机ping接keepalived的ip，看是否能ping接成功

ping 172.18.0.201
