需求
需要从旧的jenkins服务器中将部分任务迁移到新的jenkins服务器中
迁移过程
首先需要将config.xml，jobs，workspace，plugins 这四部分内容迁移到新的Jenkins服务器，如果项目较多，任务较多，就统一打包使用scp发送过去即可
代码语言：javascript复制find . -name "yqj*" -o -name "音速*" -print0|tar -czvf /export/data/tar/123.tar.gz --null -T -这个是将查找到的文件或目录统一打包
如果不想打包，也可以直接scp过去
代码语言：javascript复制find . -name "yqj*" -o -name "音速*" -exec scp -r {} root@172.20.103.9:/ ;将上述四部分内容拷贝过去之后重启下jenkins即可。
问题
代码语言：javascript复制

解决 删除两行内容：
vim config.xml authorizationStrategy 删除 securityRealm 删除
删除完成后，重启即可
