无法启动keepalived

我正在尝试使用虚拟IP来创build负载平衡器。我使用虚拟IP来引用这个链接负载平衡器。在错误configuration之后，我先启动了备份服务器的keepalived服务，然后启动了主服务器的keepalived。问题是备份服务器的keepalived工作正常，但我无法启动主服务器的keepalived。我试着卸载keepalived并再次安装，但没有奏效。这是configuration文件

主服务器

vrrp_script chk_haproxy { script "killall -0 haproxy" # verify the pid existance interval 2 # check every 2 seconds weight 2 # add 2 points of prio if OK } vrrp_instance VI_1 { interface eth0 # interface to monitor state MASTER virtual_router_id 51 # Assign one ID for this route priority 101 # 101 on master, 100 on backup virtual_ipaddress { 192.168.0.54 # the virtual IP } track_script { chk_haproxy } }

备份服务器

 vrrp_script chk_haproxy { script "killall -0 haproxy" # verify the pid existance interval 2 # check every 2 seconds weight 2 # add 2 points of prio if OK } vrrp_instance VI_1 { interface eth0 # interface to monitor state MASTER virtual_router_id 51 # Assign one ID for this route priority 100 # 101 on master, 100 on backup virtual_ipaddress { 192.168.0.54 # the virtual IP } track_script { chk_haproxy } }

在启动Keepalived服务的同时输出主服务器

 $ sudo service keepalived start * Starting keepalived keepalived [fail]

在启动keepalived服务时备份服务器的输出

 $ sudo service keepalived start * Starting keepalived keepalived [Ok]

有没有人有build议我在做什么错在这里？

根据意见更新： 主服务器日志：

 cat /var/log/syslog | grep VRRP_Instance Here it does not prints anything which mean that the keepalived does not start on Master server

备份服务器日志：

 cat /var/log/syslog | grep VRRP_Instance Mar 27 02:39:22 ubuntu keepalived_vrrp: VRRP_Instance(VI_1) Transition to MASTER STATE Mar 27 02:39:23 ubuntu keepalived_vrrp: VRRP_Instance(VI_1) Entering to MASTER STATE Mar 27 02:39:38 ubuntu keepalived_vrrp: VRRP_Instance(VI_1) Transition to MASTER STATE Mar 27 02:39:39 ubuntu keepalived_vrrp: VRRP_Instance(VI_1) Entering to MASTER STATE Mar 27 02:52:16 ubuntu keepalived_vrrp: VRRP_Instance(VI_1) Received higher prio advert Mar 27 02:52:16 ubuntu keepalived_vrrp: VRRP_Instance(VI_1) Entering to BACKUP STATE

另外还有一件事情，我提到一个网站后，我改变了备份服务器的keepalived.conf文件中的状态以显示BACKUP状态

你configuration错误的VRRP实例。两个节点上都有state MASTER ，但只能有一个主节点。设置备份服务器state BACKUP ，它将工作。一般来说，规则很简单：

在两台服务器上相同：

virtual_router_id – 对于每组服务器都必须是uniq
virtual_ip

在两台服务器上不同：

实例名称（vrrp_instance这是实例名称{）
状态（MASTER在一个上，在另一个上备份）
优先级（每个节点uniq，主站最高）

state MASTER只能设置其中的一个节点。另外，两者都设置为state BACKUP ，它将在MASTER中按优先级自动select。
