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> GRANT ALL PRIVILEGES ON test_db.* TO user1@'%' IDENTIFIED BY 'user1_password';
mysql> flush privileges;

sudo vi /etc/mysql/my.cnf

#bind-address = 127.0.0.1
