[SOLVED] php8.1-fpm gives error says webXX.sock does not exist in multipe phps installation

Hi,

I am on debian buster with multiple PHPs [5.6,7.3(default),and 8.1] installed as instructed in How to install PHP 5.6 and 7.0 - 8.1 as PHP-FPM & FastCGI for ISPConfig 3 with apt on Debian 8 to 11 (https://www.howtoforge.com/tutorial...fig-3-from-debian-packages-on-debian-8-and-9/).

However, when I try to access a website, a critical error popped in the log (visually giving a blank page):

Code:

2022/01/27 10:02:09 [crit] 9410#9410: *10 connect() to unix:/var/lib/php8.1-fpm/web36.sock failed (2: No such file or directory)

I have chosen PHP8.1 (see https://pasteall.org/pic/dc7a0f906a42462db6e4444aa10e3807 ), yet does not create the relevant socket.

I have touched `/var/lib/php8.1-fpm/web36.sock` manually. but didn't work.

Also created /var/lib/php8.1-fpm and changed file permission 755 (Ref. https://www.howtoforge.com/communit...ol-panel-gives-502-error-after-upgrade.88330/)

Even after making changes above from the ISPConfig panel, the relevant nginx config reverts back to php5-fpm?!:

Code:

        location ~ \.php$ {
            try_files /24b548f202361d0ca790386249f540b1.htm @php;
        }

        location @php {
            try_files $uri =404;
            include /etc/nginx/fastcgi_params;
            fastcgi_pass unix:/var/lib/php5-fpm/web36.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_intercept_errors on;
        }

        location /cgi-bin/ {
            try_files $uri =404;
            include /etc/nginx/fastcgi_params;
            root /var/www/clients/client4/web36;
            gzip off;
            fastcgi_pass  unix:/var/run/fcgiwrap.socket;
            fastcgi_index index.cgi;
            fastcgi_param DOCUMENT_ROOT /web;
            fastcgi_param HOME /web;
            fastcgi_param SCRIPT_FILENAME /web$fastcgi_script_name;
            fastcgi_intercept_errors on;
        }

Manually changed ` fastcgi_pass unix:/var/lib/php5-fpm/web36.sock;` to `fastcgi_pass unix:/var/lib/php8.1-fpm/web36.sock;`, but it gets reverted back to php5-fpm again and again.

Checked the attribution of the nginx-config file with `lsattr`, but it resulted ` --------------e---- /etc/nginx/sites-available/sitename.tld.vhost`. Thus immutability is not an issue neither!

Any clue appreciated? Thanks!

 

Thanks @till

I have set:

Code:

FastCGI settings
Path to the PHP FastCGI binary: /usr/bin/php-cgi8.1
Path to the php.ini directory: /etc/php/8.1/fpm

Code:

PHP-FPM settings
Path to the PHP-FPM init script: /etc/init.d/php8.1-fpm
Path to the php.ini directory: /etc/php/8.3/fpm
Path to the PHP-FPM pool directory: /etc/php/8.1/fpm/pool.d
PHP-FPM socket directory

I have made changes to the /etc/php/8.1/fpm/php.ini in pursuant to https://www.howtoforge.com/perfect-server-debian-10-nginx-bind-dovecot-ispconfig-3.1/:

Code:

# diff /etc/php/8.1/fpm/php.ini /etc/php/8.1/cgi/php.ini
802c802
< cgi.fix_pathinfo=0
---
> ;cgi.fix_pathinfo=1
968c968
< date.timezone = "Europe/Rome"
---
> ;date.timezone =
1895c1895
< opcache.validate_root = 1
---
> ;opcache.validate_root=0

Appreciate if you can point out faulty paths in configuration. Thanks.

 

Thanks again @till for prompt reply.

Made changes as you instructed and the errors are gone, with web36 using php8.1-fpm:

Yet the webpage appears blank! Could not figure out any errors in both site log and global log! Any inputs!

 

Thanks again, I get the output of phpinfo().

However, the issue was due to the third party trying to upgrade wordpress from 4 to 5 without upgrading the wordpress DB. The issue is resolved. Cheers,

 

You had this:

Code:

Path to the php.ini directory: /etc/php/8.3/fpm

where the 8.3 probably is typo?

 

I don't think so, because the file in /etc/php/8.3/fpm/php.ini and /etc/php8.3/cgi/php.ini are same except some changes required by ISPConfig which has been diffed in the post above https://www.howtoforge.com/communit...-multipe-phps-installation.88338/#post-431672. So I don't think it was a typo.

@till If so, do one needs to change the php.ini inside cgi directory and point to that path? Appreciate your input.

 

@till Thanks for the pointer. @Taleman That was obviously a typo. Thanks for pointing it out! Cheers,
