Unix var run php php7 4 fpm sock failed 2 no such file or directory

I have a VPS since many years. Everything was working fine. The server was running PHP 7 and nginx.

Today the sites were running a bit slow. So I decided to login to the server and run a shutdown -r now.

After reboot I have 502 Bad Gateway in the browser and connect() to unix:/var/run/php5-fpm.sock failed (2: No such file or directory) in the nginx error.log.

I have no idea what could went wrong during this reboot. In journalctl I don't see any error on boot.

Mysql is starting well.

php -v
PHP 7.2.22

nginx -v
nginx version: nginx/1.12.2

Here are some parts I have in the vhosts:

        location ~ \.php$ {
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                fastcgi_pass unix:/var/run/php5-fpm.sock;
#               fastcgi_pass 127.0.0.1:9000;
                fastcgi_index index.php;
                include fastcgi_params;
        }

Maybe I was running on PHP5 and on reboot it updated to PHP7?? Would that be possible?

In yum history the last install was in 2018.

ls -la |grep php
-rwxr-xr-x.  1 root root    4696240 Jul 20  2018 php
-rwxr-xr-x.  1 root root    4589728 Jul 20  2018 php-cgi
-rwxr-xr-x.  1 root root       4776 Jul 20  2018 phpize

This last says they are there since 2018, so I doubt a new php was installed after boot. Maybe the problem is somewhere else?

P.s. I do not have a sites-enabled/ folder. The vhosts are in the /etc/nginx/vhosts.d folder.

I hope someone can help to troubleshoot and fix the issue

EDIT: I don't know if it helps. I found out that in /var/run I have only one folder php-fpm which is empty. In my other 2 VPS with similar configuration (but are stil working) there are two items: php7-fpm.sock and the folder php-fpm which is not empty.

It's like PHP is not creating the sock there?

In /etc/php-fpm.conf I have pid = /var/run/php-fpm/php-fpm.pid In /etc/php-fpm.d/www.conf I have listen = /var/run/php7-fpm.sock

EDIT2: I run service php-fpm restart and now it created the socks. And it's working.

Final questions to answer this topic: I restarted many times in the last years the server and it was always fine. Today after rebooting there was this problem. I rebooted once again and still the same problem. I had to manually restart php-fpm.

  • Why I experienced this problem?
  • What to do/check/fix in order to avoid this problem in future?

EDIT3: It was working few days. Today I decided to retry to reboot ubuntu.

After reboot, once again bad gateway.

Then I tried:

Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.

Once again:

Then I tried:

But this time, even after service php-fpm restart and running php process, I get bad gateway :(

In journalctl I see:

Any idea?
