要通过远程连接MySQL，需要做两步：
第一步是要创建一个 可以远程连接的 MySQL 用户
mysql> GRANT ALL PRIVILEGES ON username.* TO remote@"%" IDENTIFIED BY "password";
第二步是要修 改 mysql 的配置文件 /etc/mysql/my.cnf
$> sudo vi /etc/mysql/my.cnf
在旧版本中找到 skip-networking，把它注释掉就可以了
#skip-networking
在 新版本中：
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = 127.0.0.1
bind-address = 127.0.0.1 这一行要注释

bind-address = 127.0.0.1 这一行要注释
#bind-address = 127.0.0.1
或者把允许访问的 ip 填上
#bind-address = 192.168.1.100
然后重启 MySQL
$> sudo /etc/init.d/mysql restart
* Starting MySQL database server mysqld
...done.
* Checking for corrupt, not cleanly closed and upgrade needing tables.
andy@ubuntu:~$ sudo /etc/init.d/mysql start
* Starting MySQL database server mysqld
...done.
这样就可以远程访问 MySQL 了
