首先到官网下载需要的包：http://www.keepalived.org/download.html
在这之前务必保证linux系统已经安装了gcc和make
[root@localhost local]# tar -zxvf /tmp/keepalived-2.0.8.tar.gz
[root@localhost local]# cd keepalived-2.0.8/
[root@localhost keepalived-2.0.8]# ./configure --prefix=/usr/local/keepalived
如果系统出现报错
*** WARNING - this build will not support IPVS with IPv6. Please install libnl/libnl-3 dev libraries to support IPv6 with IPVS.
[root@localhost keepalived-2.0.8]# yum -y install libnl libnl-devel如果系统报错
***!!! OpenSSL is not properly installed on your system. !!!
!!! Can not include OpenSSL headers files.
[root@localhost keepalived-2.0.8]# yum -y install openssl-devel如果安装报错
***configure: error: libnfnetlink headers missing
[root@localhost keepalived-2.0.8]# yum -y install libnfnetlink-devel之后执行
[root@localhost keepalived-2.0.8]# ./configure --prefix=/usr/local/keepalived
执行成功则会出现
现在开始编译
[root@localhost keepalived-2.0.8]# make && make install二、制作快捷方式
在源文件的目录./keepalived-2.0.8/keepalived/etc/init.d下有两个个快捷启动文件和生成/usr/local/keepalived目录下一个配置文件需要复制，具体执行如下命令：
[root@centos]# cp ./keepalived-2.0.8/keepalived/etc/init.d/keepalived /etc/init.d/
[root@centos]# cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/
[root@centos]# cp ./keepalived-2.0.8/keepalived/etc/sysconfig/keepalived /etc/sysconfig/keepalived
这样就可以执行service keepalived [start | stop | reload | restart ]命令。
启动报“Starting keepalived: /bin/bash: keepalived: command not found”错误，具体日志如下：
[root@centos /]# service keepalived start
正在启动 keepalived：/bin/bash: keepalived: command not found [失败]
解决方案：
[root@centos /]# cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
[root@centos /]# service keepalived start
正在启动 keepalived： [确定]
[root@yoodb /]# cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
有上述日志信息，表示启动成功。
