How do I know if PHP
What is PHP
Does NGINX require PHP
Which port is PHP

Today was one of these days, where I getting an error on my play server out of nowhere. I changed not much in the last days so I was a little confused about that. One of the websites was unable to work. I received a 502 Bad Gateway error. The error log from the Nginx showed the following:

2020/12/07 20:22:00 [crit] 1846#1846: *5 connect() to unix:/var/run/php/example.sock failed (2: No such file or directory) while connecting to upstream, client: 89.***.***.***, server: example.com, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/website.sock:", host: "www.website.de"

First I checked the socks and found ... nothing:

root@play:~# ls -lsa /var/run/php/
total 3
0 drwxr-xr-x  2 www-data www-data 120 Dez  7 20:27 .
0 drwxr-xr-x 27 root     root     840 Dez  7 20:28 ..
0 srw-rw----  1 www-data www-data   0 Dez  7 20:27 dev.example.sock
4 -rw-r--r--  1 root     root       4 Dez  7 20:27 php7.2-fpm.pid
0 srw-rw----  1 www-data www-data   0 Dez  7 20:27 php7.2-fpm.sock

So what happened? After thinking about the so-called Nginx socket leak (see https://www.nginx.com/resources/wiki/start/topics/tutorials/debugging/#socket-leaks) I rethought my changes in the last days. I just added a subdomain to example.com (subdomain dev.example.com). I isolated the dev with their own PHP pool. The directions and permission were correct. While I reviewed the pool configs, I realized that I named the pools the same. dev.example.com AND example.com were configurated under [example]. And that was the problem. PHP was still able to start, but instead of throwing an error, the two configs (which different socks) were running under the newer sock (dev.example.sock).

The fix: just change the name of the pool (now I had two pools [dev.example] and [example]) and restart the PHP service. That's it.

I have configured my LEMP server as such, but I have an error. does not charge I get NOT FOUND

I tried to do this, but I can not open the file. I get all white

it’s as if the directory did not exist

How do I know if PHP

To find out php version installed on the server type any one of the following commands on your server. Open the terminal prompt and then type the following commands. Are you using php-fpm? Get php version using the php-fmp -v or php-fpm73 -v command.

What is PHP

A: PHP-FPM (FastCGI Process Manager) is a web tool used to speed up the performance of a website. It is much faster than traditional CGI based methods and has the ability to handle tremendous loads simultaneously.

Does NGINX require PHP

PHP-FPM (FastCGI Process Manager) is an alternative to FastCGI implementation of PHP with some additional features useful for sites with high traffic. It is the preferred method of processing PHP pages with NGINX and is faster than traditional CGI based methods such as SUPHP or mod_php for running a PHP script.

Which port is PHP

By default, this configuration starts a PHP-FPM server listening on port 9000 that binds to 127.0. 0.1 (localhost). If your intention is to run PHP-FPM on a separate server, then you will need to amend the following values in your PHP-FPM domain configuration file.
