用戶授權(quán)在mysql中使用grant命令就可以了，我相信各位都會(huì)有了解過了，下面小編為各位介紹一個(gè)Mysql下建立用戶授權(quán)權(quán)限例子，希望本文章對(duì)各位有幫助．
建立用戶，授權(quán)數(shù)據(jù)庫(kù)：
mysql> create user identified by 'admin123'; #建立主機(jī)為localhost，密碼為admin123的用戶byrd
Query OK, 0 rows affected (0.05 sec)
mysql> show grants for ; #查看byrd權(quán)限，USAGE表示連接權(quán)限
+-------------------------------------------------------------------------------------------------------------+
| Grants for |
+-------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 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; #用戶byrd、主機(jī)localhost對(duì)數(shù)據(jù)庫(kù)gbk擁有所有權(quán)限
Query OK, 0 rows affected (0.01 sec)
mysql> show mysqls for ;
+-------------------------------------------------------------------------------------------------------------+
| Grants for |
+-------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO IDENTIFIED BY PASSWORD '*01A6717B58FF5C7EAFFF6CB7C96F7428EA65FE4C' |
| GRANT ALL PRIVILEGES ON `gbk`.* TO |
+-------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)
mysql> flush privileges;
mysql> grant all on gbk.* to identified by 'admin123'; #建立用戶test，用戶gbk數(shù)據(jù)庫(kù)所有權(quán)限，同上
mysql> show grants for ;
+-------------------------------------------------------------------------------------------------------------+
| Grants for |
+-------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO IDENTIFIED BY PASSWORD '*01A6717B58FF5C7EAFFF6CB7C96F7428EA65FE4C' |
| GRANT ALL PRIVILEGES ON `gbk`.* TO|
+-------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)
Query OK, 0 rows affected (0.00 sec)
遠(yuǎn)程連接同上：
mysql> grant all on gbk.* to 授權(quán)可連接主機(jī)' identified by 'admin123'; #這是Server端
[root@lamp ~]# /usr/local/mysql/bin/mysql -uroot -p'admin123' -h hk.t4x.org #這是client端
補(bǔ)充：ALL PRIVILEGES權(quán)限包括：
mysql> show grants for ;
+-------------------------------------------------------------------------------------------------------------+
| Grants for |
+-------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO IDENTIFIED BY PASSWORD '*01A6717B58FF5C7EAFFF6CB7C96F7428EA65FE4C' |
| GRANT ALL PRIVILEGES ON `gbk`.* TO |
+-------------------------------------------------------------------------------------------------------------+
mysql> revoke insert on `gbk`.* from ;
Query OK, 0 rows affected (0.00 sec)
mysql> show grants for ;
+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Grants for |
+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO IDENTIFIED BY PASSWORD '*01A6717B58FF5C7EAFFF6CB7C96F7428EA65FE4C' |
| GRANT SELECT, UPDATE, DELETE, CREATE, DROP, REFERENCES, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, EVENT, TRIGGER ON `gbk`.* TO |
+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
ALL PRIVILEGES權(quán)限包括：GRANT SELECT, UPDATE, DELETE, CREATE, DROP, REFERENCES, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, EVENT,insert
