背景：

因harbor镜像仓库长期没有进行维护工作，导致harbor镜像仓库的admin账号的密码忘记了，需要进行重置处理。

admin密码重置过程：

1、登入到db数据库中修改admin密码为初始密码：

登入到harbor-db容器中：

service@harbor:~/harbor$ docker exec -it harbor-db /bin/bash
root [ / ]# 

登入到harbor-db的pg数据库服务中： 

root [ / ]# psql -h postgresql -d postgres -U postgres
Password for user postgres: 
psql (9.6.10)
Type "help" for help.

postgres=#

切换到registry数据库中：

postgres=# \c registry
You are now connected to database "registry" as user "postgres".

查看harbor-user表中admin用户的信息：

registry=# select * from harbor_user where username='admin';
 user_id | username |       email       |             password             |   realname   |  comment   | deleted | reset_uuid |               salt               | sysadm
in_flag |       creation_time        |        update_time         
---------+----------+-------------------+----------------------------------+--------------+------------+---------+------------+----------------------------------+-------
--------+----------------------------+----------------------------
       1 | admin    | admin@example.com | 694766cd830dd50c98e9229bc4c9f8ea | system admin | admin user | f       |            | h96f0iyfmiunf8nmioi3lj0l9bkxcmzf | t     
        | 2019-01-09 05:52:01.245753 | 2021-03-19 02:24:50.109346
(1 row)

重置admin的密码，并退出pg数据库服务和harbor-db容器：

registry=# update harbor_user set salt='', password='' where username='admin';
UPDATE 1
registry-# \q
root [ / ]# exit

2、重新生效harbor服务

这里的重置不会修改harbor的镜像数据的，所以放心的进行重置操作

3、验证harbor服务是否能登入

 查看初始化的密码，在harbor的安装目录的harbor.cfg文件中存在的。

service@harbor:~/harbor$ cat harbor.cfg | grep harbor_admin
harbor_admin_password = Harbor12345

大家浏览器界面使用admin/Harbor12345登入：
