mysql创建用户并给用户分配权限

1.登录Mysql

[root@xufeng Desktop]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 6
2.添加新的用户

允许本地 IP访问localhost的Mysql数据库

mysql> create user 'editest'@'localhost' identified by 'editest123456';
Query OK, 0 rows affected (0.06 sec)
允许外网IP访问数据库editest，本命令包含上面的命令，是所有的IP都可以访问该数据库

mysql> create user 'editest'@'%' identified by 'editest123456';
Query OK, 0 rows affected (0.00 sec)
用户创建完成后，刷新授权

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
3.创建一个新的数据库，并使用show databases命令查看数据库是否创建OK

mysql> create database editestdb DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
Query OK, 1 row affected (0.01 sec)

mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| confluence |
| editestdb |
| mysql |
| performance_schema |
| sys |
+--------------------+
6 rows in set (0.00 sec)
4.将改用户editest赋权给数据库editestdb，并刷新授权

mysql> grant all privileges on `editestdb`.* to 'editest'@'localhost' identified by 'editest123456' with grant option;
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> grant all privileges on `editestdb`.* to 'editest'@'%' identified by 'editest123456' with grant option;
Query OK, 0 rows affected, 1 warning (0.01 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
5.退出 root 重新登录，使用editest登录检查本地登录是否正常，输入密码后，正常登录，并使用show databases命令查看数据库赋权是否正常。

[root@xufeng Desktop]# mysql -u editest -p
Enter password:
