场景
在Ubuntu Server中进行安装keepalived ，如果安装过程中出现纰漏，想要重新安装keepalived或者就是想直接卸载keepalived。
我们在安装keepalived时指定过安装路径为 /usr/local/src/keepalived
./configure --prefix=/usr/local/keepalived
实现
所以在卸载时也需要先进入到安装目录
cd /usr/local/src/keepalived
make uninstall #执行卸载
删除相关文件
rm -f /usr/local/sbin/keepalived
rm -f /usr/local/etc/rc.d/init.d/keepalived
rm -f /usr/local/etc/sysconfig/keepalived
rm -rf /usr/local/etc/keepalived
rm -f /usr/local/bin/genhash
删除完成后查看相关的几个目录
/usr/local/src
/usr/local
/etc
查询这几个目录下是否含有keepalived相关的目录或者文件，
文件使用rm -f **删除
文件夹使用rm -rf **删除
