Jenkin-Jenkins忘记密码
方法一修改JENKINS_HOME/users/user/config.xml文件就是用户的密码文件。对于yum install Jenkins 安装的Jenkins，它的home目录位于/var/lib/jenkins;
在Tomcat里面安装的Jenkins，在用户的家目录下.jenkins/users/user/config.xml
备份原文件：
# ls -al |grep jenkins
drwxr-xr-x12 root root 4096 Dec2 09:48 .jenkins
# cd .jenkins/users/admin/
# ls
config.xml
# vi config.xml
修改config.xml，找到passwordHash部分，替换原有的hash值
原始文件

修改原始admin的密码
#jbcrypt:$2a$10$m6dySNKzsh6Q49.POLYxsuB3dUfhoMGxQtU3vDhgqT.OMKySPJs9O
替换为111111
#jbcrypt:$2a$10$DdaWzN64JgUtLdvxWIflcuQu2fgrrMSAMabF5TSrGK5nXitqK9ZMS
重启Jenkins
# ./shutdown.sh
# ./startup.sh
方法二
进入Jenkins备份config.xml文件
# cd /root/.jenkins/
# pwd
/root/.jenkins
# cp config.xml config.xml_20171204
# vi config.xml
修改
<useSecurity>true</useSecurity> 为<useSecurity>false</useSecurity> <authorizationStrategy>。。。全部删除。。。</authorizationStrategy>
重启Jenkins
# ./shutdown.sh
# ./startup.sh
