jenkins忘记密码

修改jenkins里users的配置文件即可，如下

[root@\ jenkins]# cd /var/lib/jenkins/users/
[root@\ jenkins/var/lib/jenkins/users]# ll
drwx------. 2 jenkins jenkins  24 Apr 19 19:06 admin_3687577506749795024
-rw-r--r--. 1 jenkins jenkins 300 Apr 16 18:15 users.xml

[root@\ jenkins/var/lib/jenkins/users]# cd admin_3687577506749795024/
[root@\ jenkins/var/lib/jenkins/users/admin_3687577506749795024]# ll
-rw-r--r--. 1 jenkins jenkins 1554 Apr 16 18:16 config.xml

[root@\ jenkins/var/lib/jenkins/users/admin_3687577506749795024]# vim config.xml
     ... ...<passwordHash>#jbcrypt:$2a$10$iEWrySWxZsma4GgXdPpbK.KhNGHRVp8AEr6f.tB6QVcqjyle1.ZWu</passwordHash>

... ...
原内容 <passwordHash>开头，</passwordHash>结尾；中间的删掉更改为
#jbcrypt:$2a$10$MiIVR0rr/UhQBqT.bBq0QehTiQVqgNpUGyWW2nJObaVAM/2xSQdSq
