MySQL5.5中
mysql> grant all on *.* to oldboy@'%' identified by '123456' with grant option; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)
用戶:oldboy@'%',遠程和本地都可以登錄MySQL
MySQL5.6中
mysql> grant all on *.* to oldboy@'%' identified by '123456' with grant option; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)
用戶:oldboy@'%',遠程可以登錄MySQL,但是本地登錄就會報錯,報錯如下:
[root@szxsfb02-db-56 3306]# mysql -uoldboy -p123456 -S /data/3306/mysql.sock Warning: Using a password on the command line interface can be insecure. ERROR 1045 (28000): Access denied for user 'oldboy'@'localhost' (using password: YES)
要想本地登錄必須本地授權
mysql> grant all on *.* to oldboy@localhost identified by '123456' with grant option; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)
然後再本地登錄即可
