Windows 系统安装 Mysql 8.0+

一、Oracle官网下载对应Mysql的版本：
点击下载Mysql8.0

如图：

二、下载后解压，放到指定的位置，我这边放入 E:/MySQL80

三、在 E:/MySQL80目录下创建配置文件 (my.ini) ：
my.ini

四、进入 E:\MySQL80 目录下，

bash 复制代码

   # 创建数据目录
   mkdir data
   # 创建安全文件目录
  mkdir Uploads

五、初始化 MySQL（生成临时密码）

bash 复制代码

.\mysqld --defaults-file="E:\MySQL80\my.ini" --initialize --console --explicit_defaults_for_timestamp

六、安装和启动 Windows 服务

bash 复制代码

# 安装 MySQL 服务
.\mysqld --install MySQL80--defaults-file="E:/MySQL80/my.ini"

# 检查服务是否创建成功
Get-Service MySQL80

# 启动服务
Start-Service MySQL80

# 设置服务为自动启动
Set-Service -Name MySQL80 -StartupType Automatic

# 验证服务状态
Get-Service MySQL80 | Select-Object Name, Status, StartType

打开服务界面可以看到

修改 root 密码

bash 复制代码

# 使用临时密码登录
.\mysql -u root -p

# 输入刚才记录的临时密码

# 在 MySQL 命令行中执行：
# 1. 修改 root 密码
ALTER USER 'root'@'localhost' IDENTIFIED BY 'YourStrong@Password123';

# 2. 刷新权限
FLUSH PRIVILEGES;

# 3. 退出
exit
