1,首先我們到官方網站下載最新版本的軟體get http://www.keepalived.org/software/keepalived-1.2.2.tar.gztar zxvf keepalived-1.2.2.tar.gzcd keepalived-1.2.2./configure --prefix=/appsdata/apps/keepalivemakemake installfind / -name keepalived

1. 查看keepalived位置

cp /appsdata/apps/keepalive/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/cp /appsdata/apps/keepaliveetc/sysconfig/keepalived /etc/sysconfig/mkdir /etc/keepalivedcp /appsdata/apps/keepalive/etc/keepalived/keepalived.conf /etc/keepalived/cp /appsdata/apps/keepalive/sbin/keepalived /usr/sbin/啟動keepalivedservice keepalived start|stop|restart
以上成功安裝完畢 下面進行配置文件的設置
