linux安装和配置keepalived，史上最简单的教程

解决方法：

之前我都是到网上把keepalived-2.0.7.tar.gz下载下来安装配置，都不成功，所以试试用命令行安装，感觉超级方便，没错误。

我的主机是centos6.6，执行以下命令即可安装，如果有错误就先解决错误：

yum -y install keepalived

启动执行命令:service keepalived start

检测是否安装成功：

执行ps -ef|grep keepalived，正确的话会有几行，不成功就只有root 12666 6800 0 09:36 pts/0 00:00:00 grep keepalived这句话

root 12651 1 0 09:35 ? 00:00:00 /usr/sbin/keepalived -D

root 12652 12651 0 09:35 ? 00:00:00 /usr/sbin/keepalived -D

root 12653 12651 0 09:35 ? 00:00:00 /usr/sbin/keepalived -D

root 12666 6800 0 09:36 pts/0 00:00:00 grep keepalived

要配置keepalived结合nginx实现主从的话可以到/etc/keepalived/keepalived.conf中配置
