1. sudo apt-get install mysql-server

2. 公网访问配置

mysql -u root -p

use mysql;

所有主机能够访问

GRANT ALL PRIVILEGES ON *.* TO ‘root’@’%’ IDENTIFIED BY ‘you_password’ WITH GRANT OPTION;

flush privileges;

有限制主机访问的

GRANT ALL PRIVILEGES ON *.* TO ‘root’@’you_ip’ IDENTIFIED BY ‘you_password’ WITH GRANT OPTION;

flush privileges;

3.出现”ERROR 2003 (HY000): Can’t connect to MySQL server on ‘localhost’ (10061)” 查看 /etc/mysql/my.cnf msyql默认的bind-address是127.0.0.1 将其改成0.0.0.0，然后 /etc/init.d/mysql restart 重启服务器
