# 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统
max_connect_errors=10
# 服务端使用的字符集默认为UTF8
character-set-server=utf8
# 创建新表时将使用的默认存储引擎

MySQL密码设置：

#mysq 5.7之前版本
mysql> UPDATE user SET password=PASSWORD(“new password”) WHERE user='username';

#mysql 5.7及之后版本：
mysql> UPDATE user SET authentication_string=PASSWORD(“new_password”) WHERE user='root';

//刷新系统权限表
mysql> FLUSH PRIVILEGES;

MySQL删除用户名为空的用户：

delete from mysql.user where user='';

MySQL允许远程登陆：

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'youpassword' WITH GRANT OPTION;

三、重置密码

1. 管理员启动cmd(确定MySQL添加path并且注册注册表)
2. 关闭mysql：net stop mysql
3. 输入：mysqld --shared-memory --skip-grant-tables
4. 直接进入MySQL登陆：mysql
5. 输入：FLUSH PRIVILEGES;
6. 更改密码：update mysql.user set password=password("123456") where user="root";
7. 输入：FLUSH PRIVILEGES;
8. 启动MySQL：net start mysql
9. mysql -u root -p
