linux - 如何将 Jenkins 主目录从/var/lib 更改为 app 并为原始位置创建符号链接(symbolic link)，因为工作不会受到影响

Question

I need to change my Jenkins 2.89.3 version Home Directory from /Var/lib/jenkins to /app due to space constraints. I need to make sure , all jobs which are using the /var/lib/jenkins directory wont get affected by this migration. how to perform this operation and ran my jenkins job as expected

Current size of /var/lib/jenkins 5.1G
Move all contents to /app/
run jenkins jobs without any issues 

请帮忙完成这次迁移

您可以使用符号链接(symbolic link)来做到这一点:

1. 关闭你的 Jenkins。

2. 将所有文件从 /var/lib/jenkins 移动到 /app/jenkins

   mv /var/lib/jenkins /app/
   

3. 用指向 /app/jenkins 的符号链接(symbolic link)替换 ​​/var/lib/jenkins

   ln -s /app/jenkins /var/lib/jenkins
   

4. 再次启动 Jenkins。

这样所有文件实际上都存储在 /app 下，但由于符号链接(symbolic link)，所有到 /var/lib/jenkins 的路径都保持有效。
