maven私服nexus忘记密码，解决方法

1、vi data/db/security/user.pcl

2、找到这个地方：admin^{ZAdministrator}HUser^{[email protected]<8c>}B$shiro1$SHA-512$1024$NE+wqQq/TmjZMvfI7ENh/g==$V4yPw8T64UQ6GfJfxYq2hLsVrBY8D1v+bktfOxGdt4b/9BthpWPNUy/CBk6V9iA0nHpzYzJFWO8v/tZFtES8CA==

将1024后面的131个字符删除掉，然后用上述131个字符替换

3、重启nexus3 ，admin密码恢复为admin123

方式一：

（1）找到nexus的程序路径和Maven仓库路径：

nexus-2.14.2-01 目录为程序路径，里面有 logs、bin、conf、tmp 等目录 
sonatype-work   目录为Maven仓库路径  


nexus-2.14.2-01 目录为程序路径，里面有 logs、bin、conf、tmp 等目录 
sonatype-work   目录为Maven仓库路径

（2）在Maven仓库路径下有一个文件security.xml，文件中有用户和密码以及权限的分配：

	sonatype-work/nexus/conf/security.xml
	sonatype-work/nexus/conf/security.xml
	<?xml version="1.0" encoding="UTF-8"?>

• 将忘记密码的用户的password节点信息用f865b53623b121fd34ee5426c792e5c33af8c227字符串替换，这样密码就重置为admin123;
• 找到nexus的程序路径nexus的bin目录，重启nexus服务./nexus restart,重启完成之后admin用户的密码就重置成了admin123了；
