1.透過mysql資料庫的user表查看使用者相關資訊
mysql> use mysql Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> select host,user,password from user ;+-----------+------+-------------------------------------------+ | host | user | password | +-----------+------+-------------------------------------------+ | localhost | root | *87F2746835A04895BB77E12AA5054A767******* | | qxyw | root | | | 127.0.0.1 | root | | | localhost | | | | qxyw | | | +-----------+------+-------------------------------------------+ 5 rows in set (0.00 sec)
#2.建立資料庫
mysql> create database [databasename] default character set utf8 collate utf8_general_ci; Query OK, 1 row affected (0.00 sec)
# #3.建立使用者
mysql> create user 'dba'@'%' identified by '*******'; Query OK, 0 rows affected (0.00 sec)
#
mysql> grant select,insert,update,delete,create on [databasename].* to dba; Query OK, 0 rows affected (0.00 sec)注意:修改完權限以後一定要刷新服務,或重新啟動服務,刷新服務用:FLUSH PRIVILEGES
#5.可以透過show grants指令查看權限,若想要在原來的基礎上增加權限則繼續執行grant
mysql> grant drop on [databasename].* to dba; Query OK, 0 rows affected (0.00 sec) mysql> show grants for dba;+----------------------------------------------------------------------------------------------------+ | Grants for dba@% | +----------------------------------------------------------------------------------------------------+ | GRANT USAGE ON *.* TO 'dba'@'%' IDENTIFIED BY PASSWORD '*****************************************' | | GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP ON `[databasename]`.* TO 'dba'@'%' | +----------------------------------------------------------------------------------------------------+ 2 rows in set (0.00 sec)
mysql> revoke drop on [databasename].* from dba; Query OK, 0 rows affected (0.00 sec) mysql> show grants for dba;+----------------------------------------------------------------------------------------------------+ | Grants for dba@% | +----------------------------------------------------------------------------------------------------+ | GRANT USAGE ON *.* TO 'dba'@'%' IDENTIFIED BY PASSWORD '*****************************************' | | GRANT SELECT, INSERT, UPDATE, DELETE, CREATE ON `[databasename]`.* TO 'dba'@'%' | +----------------------------------------------------------------------------------------------------+ 2 rows in set (0.00 sec)
