1. 创建 mysql 用户:user1
mysql> CREATE USER 'user1'@'localhost' IDENTIFIED BY 'user1_password';
2. 创建数据库:test_db
mysql> CREATE DATABASE IF NOT EXISTS `test_db` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;
3. 用户授权数据库

mysql> GRANT ALL PRIVILEGES ON test_db.* TO user1@'localhost';
mysql> flush privileges;
4. 开启远程访问,使用如下:
mysql> GRANT ALL PRIVILEGES ON test_db.* TO user1@'%' IDENTIFIED BY 'user1_password';
mysql> flush privileges;

#bind-address = 127.0.0.1
重启 mysql
sudo service mysql restart
