The solution to the inability to open nginx -t and other commands

Download and install Nginx on Windows, and configure environment variables to use Nginx globally. However, commands such as nginx -t still cannot be opened.

reason:

When Nginx is in use, conf-path is found according to the relative path. The matching path is C:\Users\20210121/conf/nginx.conf, which is completely wrong.

Solution:

Make a donginx.bat (the command changes according to the name, for example, here the command starts with donginx, if the bat name is aaa.bat, then the command starts with aaa) file, and change the nginx life.

1) donginx.bat code

@echo off 
if "%1"=="help" (goto help) else (if "%1"=="-h" goto help) 
if "%1"=="version" (goto version) else (if "%1"=="-v" goto version) 
if "%1"=="start" goto start 
if "%1"=="stop" goto stop 
if "%1"=="reload" goto reloadmd 
if "%1"=="reopen" goto reopen 
if "%1"=="find" goto find 
goto error 
 
:help 
nginx -v 
echo Usage: donginx [-h,help] [-v,version] [start] [stop] [stop -a] [reload] [reopen] [find] 
echoecho= 
echo Options: 
echo   help,-h         : this help 
echo   version,-v      : show current nginx version 
echo   start           : start nginx master process 
echo   stop            : stop the newest nginx master process 
echo   stop -a         : stop all nginx master processes 
echo   reload          : reload configuration 
echo   reopen          : reopen nginx 
echo   find            : show the nginx master process list 
echo= 
exit /B 
 
:version 
nginx -v 
exit /B 
 
:start 
start nginx -p C:\nginx-1.20.1 
exit /B 
 
:stop 
if "%2"=="-a" (taskkill /F /IM nginx.exe) else (if "%2"=="" (nginx -s stop -p C:\nginx-1.20.1) else goto error) 
exit /B 
 
:reload 
nginx -s reload -p C:\nginx-1.20.1 
exit /B 
 
:find 
tasklist /fi "imagename eq nginx.exe" 
exit /B 
 
:error 
echo donginx: invalid option: "%1 %2" 
echo=    
exit /B 

explain

1. @echo off: This command is divided into @ and echo off. @ makes the execution process of the command following it not printed out, and echo off makes the execution process of all commands not printed out (test it yourself and see the result to understand).
2. goto and :: are used together, : is equivalent to a label, and goto specifies to jump to execute after that label.
3. echo: Print a line of specified characters to the command window, echo= print an empty string, and the result is equivalent to a newline.
4. exit: This command is to exit the program and close the command window (this is not what I want). If /B is specified, the command window will not be closed after exiting the program. /B means to return to the window where the previous command was located.

2) Put donginx.bat in the same directory as nginx.exe

3) In the environment variable system variable > path > new > C:\nginx-1.20.1

4) Any cmd or powershell window can execute donginx + commands

Order:

donginx help,-h : this help
donginx version,-v : show current nginx version
donginx start : start nginx master process
donginx stop : stop the newest nginx master process
donginx stop -a : stop all nginx master processes
donginx reload : reload configuration
donginx reopen : reopen nginx
donginx find : show the nginx master process list
