Ubuntu14.04下如何开启Mysql远程访问

在目录/etc/mysql下找到my.cnf，用vim编辑，找到my.cnf里面的

#bind-address           = 127.0.0.1

将其只能本地ip访问的代码进行注释

然后用root登陆Mysql数据库

im@58user:~$ mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 6
Server version: 5.5.53-0ubuntu0.14.04.1 (Ubuntu)

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

mysql> 

然后在执行

mysql> grant all on *.* to root@'%' identified by '123';
myslq> flush privileges;

最后就可以在远程用刚才创建的用户和密码登陆mysql。

在执行对用户授权密码的时候可能会遇到下面的错误：

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

解决方法：

先刷新一下权限表。
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
mysql> grant all on cactidb.* to dbuser@'localhost' identified by '123';
Query OK, 0 rows affected (0.00 sec)
