首先，下载：
http://www.keepalived.org/software/keepalived-1.2.2.tar.gz
然后，编译安装：
keeepalived时需要支持LVS时才可以做LVS调度，执行./configure 出现下面情况，将不支持lvs！：
Keepalived configuration
------------------------
Keepalived version : 1.2.2
Compiler : gcc
Compiler flags : -g -O2 -DETHERTYPE_IPV6=0x86dd
Extra Lib : -lpopt -lssl -lcrypto
Use IPVS Framework : No
IPVS sync daemon support : No
Use VRRP Framework : Yes
Use Debug flags : No
原因：是keepalived需要kernelsource的支持。
解决办法：指定kernel目录（没有安装kernel-devel的同学，请自行安装匹配版本的kernel-devel包）：
./configure --with-kernel-dir=/usr/src/kernels/2.6.18-164.el5PAE-i686/ (rhel5.4_32平台）
正确情况：
Keepalived configuration
------------------------
Keepalived version : 1.2.2
Compiler : gcc
Compiler flags : -g -O2 -DETHERTYPE_IPV6=0x86dd
Extra Lib : -lpopt -lssl -lcrypto
Use IPVS Framework : Yes
IPVS sync daemon support : Yes
IPVS use libnl : No
Use VRRP Framework : Yes
Use Debug flags : No
然后在make，make install
编译过程出现的各种问题和解决方法：
1.
checking openssl/ssl.h usability... no
checking openssl/ssl.h presence... no
checking for openssl/ssl.h... no
configure: error:
!!! OpenSSL is not properly installed on your system. !!!
!!! Can not include OpenSSL headers files. !!!
解决方式：安装openssl-devel

解决方法：修改./keepalived/libipvs-2.6/ip_vs.h文件，将#include linux/types.h行移到#include sys/types.h行之后
服务脚本和配置文件的位置：
1.如果configure时不指定prefix，按默认路径安装，则：
启动命令位置：/usr/sbin/keepalived
服务脚本位置：/etc/init.d/keepalived
配置文件位置：/etc/keepalived/keepalived.conf
附加选项配置文件：/etc/sysconfig/keepalived
可执行此命令启动：/usr/sbin/keepalived -D -f /etc/keepalived/keepalived.conf
开机自启动可如下操作：
[root@localhost ~]# chkconfig --add keepalived
[root@localhost ~]# chkconfig --level 2345 keepalived on
2.如果configure时指定了prefix，如： --prefix=/opt/keepalived/，则：
启动命令位置：/opt/keepalived/sbin/keepalived
服务脚本位置：/opt/keepalived/etc/rc.d/init.d/keepalived
配置文件位置：/opt/keepalived/etc/keepalived/keepalived.conf
附加选项配置文件：/opt/keepalived/etc/sysconfig/keepalived
可执行此命令启动：/opt/keepalived/sbin/keepalived -D -f /opt/keepalived/etc/keepalived/keepalived.conf
开机自启动可如下操作：
[root@localhost ~]# cp /opt/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/keepalived (注意该文件中关于配置文件和附加选项配置文件的位置定义)
[root@localhost ~]# chkconfig --add keepalived
[root@localhost ~]# chkconfig --level 2345 keepalived on
配置文件样例：(分发模式：DR，分配策略：lc，保持时间：180s)
