问题：
配置好keepalived.conf，且启动keepalived的服务，VIP正常，不过ipvsadm -L没有任何的内容，难道我的VS配置有问题？这是啥原因呢？
[root@lvs01 keepalived]# ip a

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

    inet 192.168.1.19/32 scope global eth0
    inet 192.168.1.20/32 scope global eth0

keepalived.conf内容:

如果不用keepalived,直接用ipvsadm的命令是没有问题的。

问题解决：

启动keepalived后
[root@lvs01 ~]# service keepalived start
Starting keepalived: [  OK  ]

[root@lvs01 ~]# ps -ef|grep keep
root      3716     1  0 00:07 ?        00:00:00 keepalived -D --use-file /etc/keepalived/keepalived.conf
root      3717  3716  5 00:07 ?        00:00:00 keepalived -D --use-file /etc/keepalived/keepalived.conf
root      3720  3220  0 00:07 pts/1    00:00:00 grep keep

--------这里只看到2个进程。

/usr/local/keepalive/sbin/keepalived -D --use-file  /etc/keepalived/keepalived.conf

[root@lvs01 ~]# ps -ef|grep keep
root      3647     1  0 Sep15 ?        00:00:00 /usr/local/keepalive/sbin/keepalived --use-file /etc/keepalived/keepalived.conf
root      3648  3647  0 Sep15 ?        00:00:00 /usr/local/keepalive/sbin/keepalived --use-file /etc/keepalived/keepalived.conf
root      3649  3647  0 Sep15 ?        00:00:00 /usr/local/keepalive/sbin/keepalived --use-file /etc/keepalived/keepalived.conf
root      3693  3220  0 00:06 pts/1    00:00:00 grep keep

-------这里可以看到3个进程。

解决办法:
[root@lvs01 ~]# which keepalived
/usr/sbin/keepalived


[root@lvs01 ~]# ls -l /usr/sbin/keepalived
-rwx------ 1 root root 88616 Sep 14 22:14 /usr/sbin/keepalived

[root@lvs01 ~]# ls -l  /usr/local/keepalive/sbin/keepalived
-rwx------ 1 root root 128968 Sep 15 01:19 /usr/local/keepalive/sbin/keepalived

cp /usr/local/keepalive/sbin/keepalived  /usr/sbin/keepalived

分析的很有道理
linux中执行命令的一个模式就是在命令前面加上完整的路径信息，这个在脚本编写的时候经常使用
