在目錄/etc/mysql下找到my.cnf，用vim編輯，找到my.cnf裡面的

#bind-address           = 127.0.0.1

將其只能本地ip訪問的程式碼進行註釋

然後用root登陸Mysql資料庫

[email protected]58user:~$ mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 6

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> 
 

然後在執行

mysql> grant all on *.* to [email protected]'%' identified by '123';
myslq> flush privileges;

最後就可以在遠端用剛才建立的使用者和密碼登陸mysql。

在執行對使用者授權密碼的時候可能會遇到下面的錯誤：

ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

解決方法：

先重新整理一下許可權表。
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
mysql> grant all on cactidb.* to

[email protected]’localhost’ identified by ‘123’;
Query OK, 0 rows affected (0.00 sec)
