linux jenkins 修改 默认工作空间主目录

jenkins 安装: https://zhaosongbin.blog.csdn.net/article/details/88891242

缘由

工作中，由于Jenkins默认的主目录空间太小，出现工作空间不足的问题
jenkins的默认目录是/root/.jenkins
这是系统盘，内存有限

查看系统空间大小，我们能明确的看到/dev目录下只有50G的空间使用率已经100%

修改目录位置

修改容器中的配置

我的jenkins是在tomact容器下部署的war包

所以我要在tomact的bin目录下修改,在

#OS …上方添加配置

export JENKINS_HOME=/home/jekins

[root@master bin]# vim catalina.sh 

export JENKINS_HOME=/home/jekins
# OS specific support.  $var _must_ be set to either true or false.
cygwin=false
darwin=false
os400=false
hpux=false
case "`uname`" in
CYGWIN*) cygwin=true;;
Darwin*) darwin=true;;
OS400*) os400=true;;
HP-UX*) hpux=true;;
esac

# resolve links - $0 may be a softlink

修改 /etc/profile

在web容器启动之前修改配置

在profile文件内添加配置

export JENKINS_HOME=/home/jekins

使profile文件生效即可

source  /etc/profile
