bat脚本安装MySQL,注册Windows服务，设置root密码，新增用户，并执行脚本。此处用的MySQL5.7的压缩包版本。将MySQL移动到C:\ProgramData目录下，进行安装。

REM ====== 1. 检测服务是否已存在 ======
echo Checking existing MySQL service...
sc query %MYSQL_SERVICE_NAME% >nul 2>&1
if %errorlevel% EQU 0 (
echo MySQL service "%MYSQL_SERVICE_NAME%" already exists.
echo Installation aborted to prevent overwrite.
exit /b 0
)
REM ====== 2. 检测系统中是否已有其他 MySQL 服务 ======
set "OTHER_MYSQL_FOUND="
REM 使用 tokens=2 抓取冒号后的实际名称，并过滤掉我们自己定义的服务名
for /f "tokens=2" %%s in ('sc query state^= all ^| findstr /I "SERVICE_NAME" ^| findstr /I "MySQL"') do (
set "TEMP_SERVICE=%%s"
if /I "!TEMP_SERVICE!" NEQ "%MYSQL_SERVICE_NAME%" (
set "OTHER_MYSQL_FOUND=!TEMP_SERVICE!"
)

echo [ERROR] Another MySQL service detected: !OTHER_MYSQL_FOUND!
echo Installation aborted.
pause
exit /b 0
)
REM ====== 3. 检测端口是否被占用 ======
echo Checking port %MYSQL_PORT%...
netstat -ano | findstr ":%MYSQL_PORT% " >nul
if %errorlevel% EQU 0 (
echo Port %MYSQL_PORT% is already in use.
echo Installation aborted.
exit /b 0
)
REM ====== 4. 目录迁移逻辑 (处理路径中的括号问题) ======
REM 使用引号包裹路径，防止 (x86) 导致脚本崩溃
set "CURRENT_DIR=%~dp0"
if /I "%CURRENT_DIR%" NEQ "%BASE_DIR%\" (
echo Moving files to %BASE_DIR%...
if not exist "%TARGET_PARENT%" mkdir "%TARGET_PARENT%"
REM 复制当前目录到 ProgramData
xcopy "%~dp0*" "%BASE_DIR%\" /E /I /Y /Q >nul
if !errorlevel! EQU 0 (
echo Files moved successfully. Relaunching...
REM 关键：使用 pushd 切换环境，避免旧路径括号干扰
pushd "%BASE_DIR%"
start "" /D "%BASE_DIR%" "%BASE_DIR%\%~nx0"
exit /b 0
) else (
echo [ERROR] Failed to move files. Please run as Administrator.
pause & exit /b 1
