Ubuntu Server 下开启远程连接 MySQL，可以通过以下方式：
1.创建一个可以远程连接的 MySQL 用户
mysql> GRANT ALL PRIVILEGES ON remote.* TO remote@"%" IDENTIFIED BY "remotepwd";
2.修改 mysql 的配置文件 /etc/mysql/my.cnf
# 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
将bind-address一行注释掉或者把允许访问的 ip 填上
bind-address = 192.168.1.100
3.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.
4.远程访问 MySQL
mysql -u remote -h REMOTE_SERVER_ADDRESS -p
