jenkins运行shell脚本时读取系统环境变量

FreeStyle 的 JenkinsJob

在 freestyle 的 job 中配置执行 shell 命令后，job 在运行时默认的执行方式为

/bin/bash -xe /tmp/jenkinsxxxx.sh

[root@localhost ~]# ps -ef |grep -i jenkins jenkins 12371 1 20 16:30 ? 00:03:55 /etc/alternatives/java -Dcom.sun.akuma.Daemon=daemonized -Djava.awt.headless=true -DJENKINS_HOME=/var/lib/jenkins -jar /usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --daemon --httpPort=8080 --debug=5 --handlerCountMax=100 --handlerCountMaxIdle=20 jenkins 27359 12371 0 16:48 ? 00:00:00 /bin/sh -xe /tmp/jenkins6138408577395354213.sh jenkins 27360 27359 0 16:48 ? 00:00:00 sleep 30

/bin/sh -xe xxx.sh方式运行的 shell 为非交互式非登录的模式，这种模式下的 shell 在启动时不会读取/etc/profile 中的内容，所以/etc/profile 中定义的环境变量不能访问

解决方法:

在 shell 中添加 #!/bin/bash -ilex，将 shell 模式修改为交互登录模式即可。

注意, #!/bin/bash -ilex 一定要在首行

 

pipeline 模式的 JenkinsJob

pipeline 模式下的原因与解决方案与 FreeStyle 类似，只是 pipeline 模式下脚本运行的进程不是 jenkins 主进程直接 fork 出来的。
