Mysql8.0.18安装

1. 创建data目录
   
2. 修改my.ini文件
   
   3.以管理员身份运行cmd
   4.执行mysqld --initialize --console，保存密码
   
   5.执行mysqld --install mysql8.0.18
   
   6.执行net start mysql8.0.18
   
   7.mysql -u root -p 输入保存的密码
   
   8.修改密码ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';
   9.其他命令sc delete mysql8.0.18
   当使用sql yog报错时：
   ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘password’ PASSWORD EXPIRE NEVER; #修改加密规则
   ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘password’; #更新一下用户的密码
   FLUSH PRIVILEGES; #刷新权限
   alter user ‘root’@‘localhost’ identified by ‘1234’;#重置密码，1234就是变更后的密码
