Install script fails to detect "proxy_cache_path"

[fidoboy]

The supplied bash script fails to detect the path when in proxy_cache mode because it only searches for fastcgi cache paths. Also there is another issue if the path in manual-configs.nginx ends with slash. Then the directory is not created rightly. It could be better if the script detects if there is a slash at the end of the path.

The plugin also fails to detect nginx when it's a proxied environment (nginx -> apache -> php-fpm) So in nginx.conf the cache paths are like that: proxy_cache_path /var/cache/nginx/ levels=1:2 keys_zone= ....

Wordpress plugin page says: "This plugin, NPP, allows WordPress users to manage Nginx Cache Purge and Preload (FastCGI, Proxy, SCGI, UWSGI) operations directly from the WordPress admin dashboard, enhancing website performance and caching efficiency." but I'm afraid that it only works in FastCGI and not with proxy_pass as it is right now.

This both issues should be fixed.

Hello @fidoboy

Thank you for your feedback. I will check as soon as possible. If you have a time you are welcome for PR to main misc/npp-setup.sh

Unfortunately I have no no time right now to develop the required code and improve the plugin as it's needed, but I can help with testing and giving ideas. My current setup is with nginx as reverse proxy server and cache, and Apache to PHP-FPM as backend, so I can test all new features and improvements related to this kind of setup. I'll keep an eye into the GitHub page to see when there is a new update or a beta release to test it as soon as it's available. Just tell me if you need to make some specific tests or if you need to know something specific about this particular setup.As I told you in my previous email, the main issues are with the bash installation script and also with the detection functions in WordPress. When using proxy cache and not fastcfgi all main nginx directives are almost the same but the name starts with the word "proxy". So the cache path is for example "proxy_cache_path" almost the same than when using FastCGI (fastcgi_cache_path). The needed changes into the script are minimal to get it working. And it happens the same with the PHP code for WordPress. You need to know that when nginx acts as a reverse proxy, the server_software header returned contains the word "apache" and not "nginx" as the plugin code is expecting right now to work. Just tell me if you have questions or need to know something more.Kind regards,FidoBoyEl 9 nov. 2025 18:34, Hasan ÇALIŞIR ***@***.***> escribió:hsntgm left a comment (psaux-it/nginx-fastcgi-cache-purge-and-preload#36) Hello @fidoboy Thank you for your feedback.

Thank you. Also you are welcome for Spanish translation of NPP here.

[fidoboy]

As soon as I can have the plugin working with proxy cache, I'll translate its interface into Spanish, no doubt. Regards,El 17 nov. 2025 6:15, Hasan ÇALIŞIR ***@***.***> escribió:hsntgm left a comment (psaux-it/nginx-fastcgi-cache-purge-and-preload#36) Thank you.

@fidoboy Fair deal 😊

I’ve updated the script; please check if it works for you now.
I thing it fixes the / issue and detects the proxy_cache_path and also scgi_cache_path|uwsgi_cache_path

Switch to root user:

sudo su - root || su - root
bash <(curl -Ss https://psaux-it.github.io/install.sh)

or directly with sudo

sudo bash -c "$(curl -Ss https://psaux-it.github.io/install.sh)"

May be that the script works fine now, I'll test ASAP, but it's not the main issue anyway. I can easily bypass the script and do by hand the cache folder mapping, but the problem is with the WordPress plugin. I doesn't want to run if it doesn't detect exactly the setup for nginx FastCGI. This is the point where the code should be refactored to work with reverse proxy installations, like the Nginx in front of Apache server. The plugin should detect if the setup is like this and then activate all the functionality like it does with FastCGI. The only difference between the two modes, are the names of the Nginx directives, so it doesn't requires a lot of changes. The cache folder structure is exactly the same than when using FastCGI. So basically, you only need to fix detection issues and the best way to do it is to test it on a reverse proxy installation setup. El 17 nov. 2025 17:39, Hasan ÇALIŞIR ***@***.***> escribió:hsntgm left a comment (psaux-it/nginx-fastcgi-cache-purge-and-preload#36) As soon as I can have the plugin working with proxy cache, I'll translate its interface into Spanish, no doubt. @fidoboy Fair deal 😊 I’ve updated the script; please check if it works for you now.

Then it is time to start translation in Spanish 😊Then i will check reverse proxy installation next.

[fidoboy]

I can't translate it if I can see and use the interface. So, as I said before, it's needed to have it working in proxy cache setups to use it and translate into any language. El 17 nov. 2025 19:41, Hasan ÇALIŞIR ***@***.***> escribió:hsntgm left a comment (psaux-it/nginx-fastcgi-cache-purge-and-preload#36) May be that the script works fine now, Then it is time to start translation in Spanish 😊Then i will check reverse proxy installation next. —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you were mentioned.Message ID: ***@***.***>

It's not just a matter of fixing the bash script. The main problem is with the WordPress plugin, it doesn't work as expected with proxy cache setups. If the bash script is now fixed, then the next step is to fix the installation of the plugin in WordPress. As it is right now, all it does is to freeze the PHP-FPM process because it tries to locate something and it never ends. So there is a serious bug that happens when trying to use it with other setups that are not the FastCGI.El 17 nov. 2025 19:53, "FidoBoy ." ***@***.***> escribió:I can't translate it if I can see and use the interface.

😊 I’ll take care of this in the next NPP release for you.
In the meantime, you don’t actually need the interface for translations — even if the plugin isn’t working on your side, you can still translate everything.

[fidoboy]

Yes, you are right. But it's better and more accurate if I can really see each word or phrase into his own context. That way the translation could be better than if it's done with an automated translator.Many times, if you cannot see the working results it leads to misleading information or confusion. That's why I want to have it working to experiment with it and make a better translation.Also, the release is not for me, it's for any user that could use a nginx proxy setup on his server. I use many different setups, but currently I haven't one that uses FastCGI.El 17 nov. 2025 20:07, Hasan ÇALIŞIR ***@***.***> escribió:hsntgm left a comment (psaux-it/nginx-fastcgi-cache-purge-and-preload#36) 😊 I’ll take care of this in the next NPP release for you.
