19.5 忘记Admin密码如何做

忘记Admin密码如何做

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

有时因为时间长了，zabbix管理员账号密码给忘记了
解决办法：
- 重置zabbix密码，就是直接更改数据库里的数据即可

首先进入到mysql命令行里面

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

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

查看zabbix相关的表，以后服务器监控的主机越多，那么这些表会越来越大，所以需要去指定合适的监控策略

比如说：数据量需要保存多长时间，那么在定义这个监控项目的时候就该想到，要保留1个月还是1年，还是其他时间；
比如，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;

zabbix的密码，默认存放的表是users里面
查看users表

desc users;

mysql> desc users;

需要修改的就是passwd的表

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

查看表的情况

select * from usersG;

mysql> select * from usersG;
*************************** 1. row ***************************
        userid: 1
         alias: Admin

修改以后就可以去尝试用新密码登录zabbix了，这就是充值zabbix管理员密码
