问题：今天Jenkins使用Publish Over SSH Plugin遇到一个问题：错误如下

SSH: Connecting from host [localhost.localdomain]SSH: Connecting with configuration [47.94.8.78] ...SSH: EXEC: STDOUT/STDERR from command [rm -rf /var/tmp/garage/server/centerunzip -oq /var/tmp/remote-deploy/garage-dacheng-server.war -d /var/tmp/garage/server/centerps -ef |grep tomcat-center |awk '{print $2}'|xargs kill -9  1>/dev/null 2>&1 | exit 0service tomcat-center start] ...SSH: EXEC: completed after 1,007 msSSH: Disconnecting configuration [47.94.8.78] ...ERROR: Exception when publishing, exception message [Exec exit status not zero. Status [-1]]Build step 'Send build artifacts over SSH' changed build result to UNSTABLEFinished: UNSTABLE

“Exec exit status not zero” 说明进程没有正常结束，经过排除，问题锁定在：

ps -ef |grep tomcat-center |awk '{print $2}'|xargs kill -9  1>/dev/null 2>&1 | exit 0

分析：

ps -ef | grep tomcat-center 查询到的是两条记录（如下图）：第一条是我们要查找并关闭的，第二条是查找进程自身。

当管道进行到kill的时候，两条进程一同被杀死，而Jenkins仍然在等待查找进程自身返回exit 0，事实上它永远等不到了，因为进程都没了，

最终会报异常"Exec exit status not zero"

解决：

使用“grep -v grep”排除掉它自身就可以

原来：ps -ef |grep tomcat-center |awk '{print $2}'|xargs kill -9

改后：ps -ef |grep tomcat-center | grep -v grep |awk '{print $2}'|xargs kill -9
