Resolved connect() to unix:/var/www/vhosts/system/[domain]/php-fpm.sock failed (2: No such file or directory) while connecting to upstream

[riccardo.roscilli]

Hello,
I have to use php 5.2 for an old app. I installed it on plesk and configured the domain to run php 5.2 as fastcgi
When I try to browse the website I got

Bad Gateway​

and in the log I found the message in the object
In the dir
/var/www/vhosts/system/[domain]/
there's no php sock
Bye
Riccardo

Hi @riccardo.roscilli , thank you for posting. Could you please add what your operating system and Plesk version are? Was PHP 5.2 installed from the Plesk upgrades/updates page or was it registered as a handler manually?

 

[riccardo.roscilli]

Hi Peter,
sure
Version 18.0.49 Update #1
Centos 7
php 5.2 was installed with plesk updates
Thank you for your prompt reply

Sounds like the php-fpm.sock was never created which should had been created on startup. Maybe try changing the serving type from Nginix to Apache?

 

[riccardo.roscilli]

yes the error comes from nginx, tuned off as explained here

https://support.plesk.com/hc/en-us/articles/360006364914-How-to-make-a-website-be-processed-only-by-Apache-when-nginx-is-enabled-on-a-Plesk-server

but now the php files are downloaded, not executed

 

[scsa20]

Did you choose to run PHP as FastCGI application served by Apache with proxy unchecked?

 

[riccardo.roscilli]

with proxy unchecked it will run with nginx, with proxy checked it download the php files
this is the php configuration


and this is the nginx setting

I can't seem to replicate it in a test I have setup, here's what I have set:

I would recommend double checking the settings and reboot the server if you have not already done so.

 

[riccardo.roscilli]

I followed the same actions to create a brand new website
please, try this url

https://test.jackrusselltabarrino.com/index.php

 

[scsa20]

Eh, weird. Check if you have a .htaccess file in the root directory (if you're using the default settings it should be in your home directory of the files > test.jackrusselltabarrino.com) and make sure you have mod_fcgid installed located under Web hosting > Apache (so basically go to Tools & Settings > Plesk > Updates > Add/Remove Components, then navigate to Web hosting > Apache and make sure mod_fcgid is installed. If it is, uninstall it and reinstall it)

 

[riccardo.roscilli]

this is how plesk updates appears
the web site is brand new no other file but index.html and index.php

 

[scsa20]

OK, but did you try to uninstall and reinstall mod_fcgid?

 

[riccardo.roscilli]

uninstalled and reinstalled, nothing

 

[Peter Debik]

Do you have short open tags in your script? Have you checked the option "short open tags" (=on) in your PHP settings? Else scripts with that lead-in won't be execute, but the code will be downloaded or displayed.

 

[riccardo.roscilli]

OK, first of all, thank you very much for your support, I really appreaciate it.
I don't know what's going on under the hood, by the way after I went out to rest a couple of hours, I came back and the test site was displaying correctly the phpinfo 5.3
After that I got encouraged and infact the real site I have to migrate was showing some php errors but only with php 5.6 (deprecated mysql functions, you know). Than after your very last message, I changed again to php 5.3, set up magic_quotes_gpc and short tags on, apply and... boom! the site loaded.
A lot of errors on css loading but I know they will go away once pointed the domain and installed the ssl certificate.
Thank you again for your invaluable support.
Bye
Riccardo
