Jenkins修改默认workplace

说明：
Jenkins安装完成Job默认工作空间目录是：/var/lib/jenkins
一般var的空间几十G，所以修改默认工作空间。

1. 查看Jenkins安装信息 命令：rpm -ql jenkins

   [root@localhost jenkins]# rpm -ql jenkins
   /etc/init.d/jenkins
   /etc/logrotate.d/jenkins
   /etc/sysconfig/jenkins
   /usr/lib/jenkins
   /usr/lib/jenkins/jenkins.war
   /usr/sbin/rcjenkins
   /var/cache/jenkins
   /var/lib/jenkins
   /var/log/jenkins
   
   

   /usr/lib/jenkins/ ：安装目录war包
   /etc/sysconfig/jenkins：jenkins配置文件
   /var/lib/jenkins：工作目录JENKINS_HOME
   /var/log/jenkins/jenkins.log：日志文件

2. 关闭Jenkins 命令：service jenkins stop

   vim /etc/sysconfig/jenkins 
   

   
   /var/lib/jenkins 修改成要更换的目录；存储比较大的目录

3. 加载配置：systemctl daemon-reload
   启动：service jenkins start

4. 重新启动浏览器访问报如下错误
   没有权限
   
   做如下修改：

   vim /etc/sysconfig/jenkins 
   

   
   JENKINS_USER=“root”

5. 重新启动：service jenkins restart
