找到 Path 变量，编辑，在最未尾加上：% MYSQL_HOME%\bin

命令行初始化

用管理员打开命令行，按以下步骤一步步执行安装过程；

控制台初始化 mysql 服务；

PS C:\Program Files\mysql-8.0.25-winx64\bin> mysqld --initialize --console

需要注意：初始化完成后的未位行 “[Server] A temporary password is generated for root@localhost: oh;bZjw:xxxx”，其中的 oh;bZjw:xxxx 为 root 用户的初始化密码，需要提前记录，否则忘记后无法进入 mysql 数据库，则需要重新初始化安装生成新的 root 密码； 

安装 mysql 服务

PS C:\Program Files\mysql-8.0.25-winx64\bin> mysqld --install mysql_server
The service already exists!
The current server installed: "C:\Program Files\mysql-8.0.25-winx64\bin\mysqld.exe" mysql_server

启动 mysql 服务

PS C:\Program Files\mysql-8.0.25-winx64\bin> net start mysql_server
mysql_server 服务正在启动 .
mysql_server 服务已经启动成功。

任务管理器中查看 mysql 服务运行状态为 “正在运行”。

 

修改 mysql 密码

如果密码有特殊符号是无法被命令行解析，则用 ' 单引号包住密码

PS C:\Program Files\mysql-8.0.25-winx64\bin> mysql -u root -p'oh;bZjw:xxxx'
mysql: [Warning] Using a password on the command line interface can be insecure.

到此 mysql-8.0.25 的 zip 解压版在 windows 环境下安装完毕；本地可通过各种客户端工具进行登录访问；如要远程访问，还需要给 root 用户配置 IP 访问权限，此处不在本文讲述内，可自行查找！
