jdk+apache-tomcat+jenkins+maven搭建完成后第一次登陆，

  搭建jenkins请查看博客

浏览器输入 

印象里在搭建jenkins的时候并没有设置密码这一项

去JENKINS_HOME/user/admin目录下找到config.xml文件

<hudson.security.HudsonPrivateSecurityRealm_-Details>

<passwordHash>#jbcrypt:$2a$10$tFlvqP57QdsnABEzbdwFI./CUBj4pcfB7St8U2lwEiEn42IGK8nf6</passwordHash>

</hudson.security.HudsonPrivateSecurityRealm_-Details>

修改后==》》
