Establish a user, authorization database:

mysql> create user ' Byrd ' @ ' localhost ' identified by ' admin123 '; #建立主机为localhost, the password is admin123 user Byrd
Query OK, 0 rows affected (0.05 sec)
Mysql> show grants for ' Byrd ' @ ' localhost '; #查看byrd权限, usage indicates connection permissions
+-------------------------------------------------------------------------------------------------------------+
| Grants for Byrd@localhost |
+-------------------------------------------------------------------------------------------------------------+
| GRANT USAGE on *.* to ' Byrd ' @ ' localhost ' identified by PASSWORD ' *01a6717b58ff5c7eafff6cb7c96f7428ea65fe4c ' |
+-------------------------------------------------------------------------------------------------------------+
1 row in Set (0.00 sec)
Mysql> select User,host from Mysql.user;
+------+-----------+
| user | Host |
+------+-----------+
| Root | 127.0.0.1 |
| Root | :: 1 |
| Root | Lamp |
| Byrd | localhost |
| Root | localhost |
+------+-----------+
5 rows in Set (0.00 sec)
Mysql> Grant all on gbk.* to ' Byrd ' @ ' localhost '; #用户byrd, host localhost have all permissions on the database GBK
Query OK, 0 rows affected (0.01 sec)

Mysql> show Mysqls for ' Byrd ' @ ' localhost ';
