1.下载keepalived
下载地址：http://www.keepalived.org/，这里下载的版本是linux下的最新版：keepalived-1.4.0.tar.gz
2.安装keepalived
[root@localhost ~]# tar -zxvf keepalived-1.4.0.tar.gz
解压后需要安装gcc命令，否则在configure时会报错，如下：
[root@localhost ~]# yum install -y gcc openssl-devel popt-devel
安装好gcc后进入解压的keepalived目录下，执行
[root@localhost ~]# ./configure --prefix=/usr/local/keepalived
[root@localhost ~]# make && make install
以上步骤如果没有错误，则说明编译安装成功。但此时还不能直接使用安装的keepalived，需要拷贝几个文件到指定的目录下才可以直接使用。拷贝的文件如下：
[root@localhost ~]# cp keepalived-1.4.0/keepalived/etc/init.d/keepalived /etc/init.d/
[root@localhost ~]# mkdir /etc/keepalived
[root@localhost ~]# cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/
[root@localhost ~]# cp keepalived-1.4.0/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
[root@localhost ~]# cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
复制完后启动keepalived。
（3）启动keepalived
[root@localhost ~]# service keepalived start
Starting keepalived (via systemctl): [ 确定 ]
（4）验证是否启动成功
[root@localhost ~]# ps -aux |grep keepalived
如果输出如下：
正常启动后，这里有3条记录，其中一个是父进程，负责监控其子进程。一个是vrrp子进程，另外一个是checkers子进程。其他情况说明启动失败。
（5）设置开启启动：
[root@localhost ~]# chkconfig keepalived on
（6）卸载
卸载时，进入keepalived解压目录的keepalived目录下,执行：
[root@localhost ~]# make uninstall
然后删除相关文件，即步骤2中拷贝的几个文件。这里就不一一列出了。
