实用的kill脚本（ps -ef | grep keepalived | grep -v grep | awk ‘{print $2}‘ | xargs kill -9）

1.查看进程：

ps -ef | grep keepalived

2.grep -v grep 命令可以忽略grep这个进程

ps -ef | grep keepalived | grep -v grep

3.awk ‘{print $2}’ 命令截取进程号

 ps -ef | grep keepalived | grep -v grep | awk '{print $2}'

4.xargs 命令把前面的输出作为后面命令kill -9 的输入，也就是传左边命令截取的进程号给命令kill -9

ps -ef | grep keepalived | grep -v grep | awk '{print $2}' | xargs kill -9

5.查看是否杀死进程

ps -ef | grep keepalived
