安装lvs，参考http://www.cnblogs.com/taosim/articles/2866845.html遇到如下问题：
1.linux配置ipvsadm, /usr/src/kernels中无内核文件，经网上搜索是因为缺少kernel-devel这个包导致的，安装完成，问题解决。
[root@LB59_backup kernels]# yum -y install kernel-devel
2.[root@test keepalived-1.1.18]# ./configure --prefix=/usr/local/keepalived
configure: error:
!!! OpenSSL is not properly installed on your system. !!!
!!! Can not include OpenSSL headers files. !!!
经过搜索找到解决方法：
[root@master ~]# yum -y install openssl-devel
编译的时候出现这个提示，说明keepalived和内核结合了，如果不是这样的，需要加上这个参数./configure --with-kernel-dir=/kernel/path
Keepalived configuration（出现这个）
------------------------
Keepalived version : 1.1.18
Compiler : gcc
Compiler flags : -g -O2
Extra Lib : -lpopt -lssl -lcrypto
Use IPVS Framework : Yes
IPVS sync daemon support : Yes
Use VRRP Framework : Yes
Use Debug flags : No
3.配置keepalived
[root@test ]# cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/
[root@test ]# cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
[root@test ]# mkdir /etc/keepalived
[root@test ]# cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/
[root@test ]# cp /usr/local/keepalived/sbin/keepalived /usr/sbin
然后启动：
[root@test keepalived-1.1.18]# service keepalived start
Starting keepalived: [ OK ]
