退出-状态：-1当通过jenkins杀死进程时

Question

我使用Jenkins构建工件并将其部署到服务器。在部署文件之后，我使用kill -9 'pgrep -f service name'命令停止了服务

请注意，该服务已终止，但jenkins作业在状态代码-1中失败，尽管当我在没有jenkins的linux服务器的shell上使用该命令时，此命令运行良好。

请帮我解释一下为什么我有-1的出境身份？以及如何通过jenkins作业在linux服务器上不出故障地杀死进程？

编辑:在我的脚本中添加/bin/bash -x之后出现的以下日志：

 #/bin/bash -x
pid=$(pgrep -f service-name); echo "killing $pid"; kill -9 $pid;

编辑:命令ps -ef | grep service-name的输出是：

ps -ef | grep service-name

-审判脚本的输出：

#/bin/bash -x

pgrep -f "java -jar /root/service-name --spring.config.location=/root/service-name/application.properties" | while read pid; do

如果要终止命令行与service-name匹配的任何进程，则应更改脚本：

#/bin/bash
pgrep -f service-name | while read pid; do
   ps -ef | grep $pid   # so you can see what you are going to kill
   kill -9 $pid
done

命令pgrep每行返回一个进程列表。

为了获得由空格分隔的pid列表并调用kill命令一次：

#/bin/bash
kill -9 $(pgrep -f service-name -d " ")

为了查看pgrep所选择的进程，请使用：

pgrep -a -f sevice-name

或

ps -ef | grep service-name

使用man pgrep查看所有选项

在您的示例中，由于pgrep与作业脚本匹配，所以作业被终止，因此您应该在-x参数中使用更具体的模式：

#/bin/bash 
pgrep -xf "java -jar /root/service-name --spring.config.location=/root/service-name/application.properties" | while read pid; do
   kill -9 $pid
done
