Zabbix忘记admin登录密码重置密码的问题，具体内容如下所示：

1. 问题描述：

2. 解决问题

2.1 zabbix连接的是mysql数据库

[root@zabbix ~]# mysql
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 52
Server version: 5.5.65-MariaDB MariaDB Server

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> 

2.2 进入mysql数据库以后查询users表

MariaDB [zabbix]> use zabbix;
MariaDB [zabbix]> select userid,alias,passwd from users;
+--------+-------+----------------------------------+
| userid | alias | passwd                           |
+--------+-------+----------------------------------+
|      1 | Admin | a8105204604a0b11e916f3879aae3b0b |
|      2 | guest | d41d8cd98f00b204e9800998ecf8427e |
+--------+-------+----------------------------------+
2 rows in set (0.00 sec)

2.3 生成一个新密码MD5，admin是密码

[root@zabbix ~]# echo -n admin | openssl md5
(stdin)= 21232f297a57a5a743894a0e4a801fc3

2.4 然后update表数据，userid=1的这个用户

MariaDB [zabbix]> update users set  passwd='21232f297a57a5a743894a0e4a801fc3' where userid = '1';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0

2.5 刷新重新加载权限表

MariaDB [zabbix]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

3. 重新登陆即可
