思路
更改认证类型为Internal，然后使用Admin登陆
如果忘记密码，也可以重置Admin密码
更改认证类型为Internal
登录数据库
mysql -u root -p
mysql> use zabbix;
mysql> update config set authentication_type=0;
mysql> flush privileges;
其中，认证类型由 **authentication_type，**字段决定，值可以为0,1和2。0 代表Internal,1代表
LDAP，2代表HTTP
mysql> update config set authentication_type=0;
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
修改Admin密码
#查询Admin用户的ID:
mysql> select * from users;
+--------+-------------+-------------+---------------+----------------------------------+-----+-----------+------------+-------+---------+------+---------+----------------+----------------+---------------+---------------+
| userid | alias | name | surname | passwd | url | autologin | autologout | lang | refresh | type | theme | attempt_failed | attempt_ip | attempt_clock | rows_per_page |
+--------+-------------+-------------+---------------+----------------------------------+-----+-----------+------------+-------+---------+------+---------+----------------+----------------+---------------+---------------+
| 1 | Admin | Zabbix | Administrator | 5fce1b3e34b520afeffb37ce08c7cd66 | | 1 | 0 | zh_CN | 30 | 3 | default | 4 | 192.168.100.34 | 1383812925 | 50 |
#更新Admin密码
mysql> update users set passwd='zabbix' where userid=1;
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
更改LDAP主机或者BIND DN
mysql> update config set ldap_host='xxx.xxx.xxx.xxx' ldap_base_dn='cn=ldap_search,ou=example,dc=com' ldap_bind_password='passwd';
