19.5 忘记Admin密码如何作

忘记Admin密码如何作

• 进入mysql命令行，选择zabbix库
• mysql -uroot -p zabbix
• update users set passwd=md5(‘newpasswd’) where alias=‘Admin’;
• 这样就更改了Admin用户的密码

忘记zabbix密码

• 有时由于时间长了，zabbix管理员帐号密码给忘记了
• 解决办法：
  • 重置zabbix密码，就是直接更改数据库里的数据便可

1. 首先进入到mysql命令行里面

A机器
[root@hf-01 ~]# mysql -uroot -phanfeng

2. 使用zabbix库

mysql> use zabbix
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

3. 查看zabbix相关的表，之后服务器监控的主机越多，那么这些表会愈来愈大，因此须要去指定合适的监控策略

• 好比说：数据量须要保存多长时间，那么在定义这个监控项目的时候就该想到，要保留1个月仍是1年，仍是其余时间；
• 好比，监控的站点服务量很大的话，一天就要涨好几个G，那么你的服务器磁盘能支持保存多长时间；

show tables;

4. zabbix的密码，默认存放的表是users里面
5. 查看users表

• desc users;

mysql> desc users;

• 须要修改的就是passwd的表

6. 修改密码

• update users set passwd=md5(‘newpasswd’) where alias=‘Admin’;

mysql> update users set passwd=md5('aminglinux') where alias='Admin';
Query OK, 1 row affected (0.01 sec)
Rows matched: 1  Changed: 1  Warnings: 0

7. 查看表的状况

• select * from users\G;

mysql> select * from users\G;
*************************** 1. row ***************************
        userid: 1
         alias: Admin
          name: Zabbix
