MySQL密码设置：

  1 #mysq 5.7之前版本
  2 mysql> UPDATE user SET password=PASSWORD(“new password”) WHERE user='username';
  3 
  4 #mysql 5.7及之后版本：
  5 mysql> UPDATE user SET authentication_string=PASSWORD(“new_password”) WHERE user='root';
  6 
  7 //刷新系统权限表
  8 mysql> FLUSH PRIVILEGES;
  9

MySQL删除用户名为空的用户：

  1 delete from mysql.user where user='';

MySQL允许远程登陆：

  1 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
