关于lvs+keepalived只加入一台realserver问题

今天做lvs+keepalived+mysql项目实施方案，在配置lvs+keepalived时都是ok的，但是就只加入第一台realserver。本人也感到很奇怪，lvs+keepalived本人也在实验环境下做过很多次了，但是还是出问题了，后来对比配置文件终于发现问题所在。

问题前：

[root@lvsA keepalived]# ipvsadm -Ln
IP Virtual Server version 1.2. (size=)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  10.10.1.200: rr persistent
  -> 10.10.1.201:             Route                   

解决方法：

[root@lvsA keepalived]# vim /etc/keepalived/keepalived.conf

   TCP_CHECK  {       <--在所有的realserver配置段的这里要加一个空格

问题解决后：

[root@lvsA etc]# /etc/init.d/keepalived restart                              <--重启一下keepalived
Stopping keepalived:                                       [  OK  ]
Starting keepalived:                                       [  OK  ]
[root@lvsA etc]# ipvsadm -Ln
IP Virtual Server version 1.2. (size=)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  10.10.1.200: rr persistent
  -> 10.10.1.201:             Route
  -> 10.10.1.202:             Route
  -> 10.10.1.203:             Route
[root@lvsA etc]#
