一 mysql server 下载

官网下载地址页面

https://dev.mysql.com/downloads/mysql/

二 免装版使用步骤

1 解压

下载完成后,解压文件夹,如下所示:

2 执行安装命令

D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin>mysqld --install
Service successfully installed.

3 初始化mysql

D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin>mysqld --initialize --console
2025-03-31T02:30:43.318917Z 0 [System] [MY-013169] [Server] D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin\mysqld.exe (mysqld 8.0.41) initializing of server in progress as process 8224
2025-03-31T02:30:43.344538Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.
2025-03-31T02:30:44.019707Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.
2025-03-31T02:30:46.985785Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: :W*Vd?:b123*

初始化会产生一个随机密码,在最后一行显示，记住这个密码,登录会用到

4 开启服务

D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。

5 登录

D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin>mysql -u root -h localhost -p

三 问题处理

在登录时候,可能会遇到一个问题,如下:

D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin>mysql -u root -h localhost -p
Enter password: **
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

解决步骤

# 关闭服务
net stop mysql# 通过控制台跳过密码表的加载和检查操作(不要关闭此CMD页面，另外以管理员身份打开CMD,然后输入mysql -u root,如果要求输入命令直接按Enter键跳过)
mysqld --console --skip-grant-tables --shared-memory

另外一个cmd窗口连接mqsql后,进行修改密码

D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin>mysql -u root

[SC] ChangeServiceConfig 成功
