新建遠程登錄用戶并授權

mysql> create user 'eric'@'%' identified by 'lyd2017';Query OK, 0 rows affected (0.01 sec)mysql> grant all on *.* to 'eric'@'%';--所有權限Query OK, 0 rows affected (0.00 sec)

關于授權：

命令：GRANT privileges ON databasename.tablename TO 'username'@'host'

說明：privileges-用戶的操作權限，如select，insert,update 等，如果要授予所有權則使用all

如果要授予該用戶對所有數據庫和表的操作權限則用* 表示，如 *.*

例如：

GRANT SELECT, INSERT ON mysql.tables TO 'eric'@'%';GRANT ALL ON *.* TO 'eric'@'%';
