Keepalived 主备配置

keepalived主备或多主多备,配置都是一样配置方法,只是搭建多少的问题。

1.keepalived安装

  参考:https://www.cnblogs.com/zwcry/p/9542867.html

2.keepalived.conf配置

  1)修改主keepalived.conf

   谨记:该配置慎用空格,可以使用TAB或回车排版,空格会被识别为赋值,导致keepalived运行失败

  内容如下:

! Configuration File for keepalived

vrrp_instance VI_1 {
	state MASTER#两个值(主:MASTER  备:BACKUP),必须大写
	interface ens33#网卡接口,ip a查看,上面主备搭建教程有讲
	virtual_router_id 51#虚拟路由ID,主备或多主多备,需要全部设置一样
	priority 101#优先级,越高越优先使用该服务
	advert_int 1#多个keepalived的通讯检测间隔,单位秒
	authentication {#认证类型与密码,主备或多主多备需要设置一样
		auth_type PASS
		auth_pass 1111
  }

	virtual_ipaddress {
		192.168.159.110#定义虚拟IP,换行可以定义多个
	}
}

  2)修改备keepalived.conf

   谨记:该配置慎用空格,可以使用TAB或回车排版,空格会被识别为赋值,导致keepalived运行失败

  内容如下:

! Configuration File for keepalived

vrrp_instance VI_1 {
	state BACKUP#两个值(主:MASTER  备:BACKUP),必须大写
	interface ens33#网卡接口,ip a查看,上面主备搭建教程有讲
	virtual_router_id 51#虚拟路由ID,主备或多主多备,需要全部设置一样
	priority 100#优先级,越高越优先使用该服务
	advert_int 1#多个keepalived的通讯检测间隔,单位秒
	authentication {#认证类型与密码,主备或多主多备需要设置一样
		auth_type PASS
		auth_pass 1111
  }

	virtual_ipaddress {
		192.168.159.110#定义虚拟IP,换行可以定义多个
	}
}

3.测试

  1)重启主备keepalived,查看ip信息

    systemctl restart keepalived

    ip add

    

    

 

  2)停止主keepalived,查看ip信息

    systemctl stop keepalived

    ip add

    

    

 

  3)开启主keepalived,再次查看ip信息

    systemctl start keepalived

    ip add
