1，首先我们到官方网站下载最新版本的软件
tar zxvf keepalived-1.2.2.tar.gz
cd keepalived-1.2.2
./configure --prefix=/appsdata/apps/keepalive
make
make install
find / -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/keepalived
cp /appsdata/apps/keepalive/etc/keepalived/keepalived.conf /etc/keepalived/
cp /appsdata/apps/keepalive/sbin/keepalived /usr/sbin/
启动keepalived
service keepalived start|stop|restart

以上成功安装完毕 下面进行配置文件的设置
