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.

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
