相信很多站长网站有很多个，那么每一个网站需要配置一个单独的数据库，这个时候就需要给mysql新增用户了，在平常我们都是用phpmyadmin来进行设置，但是有的时候我们需要在命令行来设置，现在随小魏来进行用命令行设置mysql增加用户。
新增用户分为3步骤
1.root 登陆
mysql -uroot -p
2. 查看数据库
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| test |
+--------------------+
4 rows in set (0.00 sec)
查看用户
mysql> select user,host from user;
+------+-----------------------+
| user | host |
+------+-----------------------+
| root | % |
| root | 127.0.0.1 |
| root | localhost |
| root | localhost.localdomain |
+------+-----------------------+
4 rows in set (0.00 sec)
3.比如我想添加一个 zabbix用户
mysql> CREATE USER 'zabbix'@'%' IDENTIFIED BY 'broadtech';
Query OK, 0 rows affected (0.00 sec)
mysql> GRANT ALL PRIVILEGES ON *.* TO 'zabbix'@'%' IDENTIFIED BY 'broadtech' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
mysql>
mysql>
mysql> select user,host from user;
+--------+-----------------------+
| user | host |
+--------+-----------------------+
| root | % |
| zabbix | % |
| root | 127.0.0.1 |
| root | localhost |
| root | localhost.localdomain |
+--------+-----------------------+
5 rows in set (0.00 sec)
比如我添加lte_v1 用户
mysql> CREATE USER 'lte_v1'@'%' IDENTIFIED BY 'broadtech';
Query OK, 0 rows affected (0.01 sec)
mysql> GRANT ALL PRIVILEGES ON *.* TO 'lte_v1'@'%' IDENTIFIED BY 'broadtech' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
mysql>
mysql> select user,host from user;
+--------+-----------------------+
| user | host |
+--------+-----------------------+
| lte_v1 | % |
| root | % |
| zabbix | % |
| root | 127.0.0.1 |
| root | localhost |
| root | localhost.localdomain |
+--------+-----------------------+
6 rows in set (0.00 sec)
当然权限设置，通过update user 来设置
记得刷新。
