php7.4-fpm service won't start on Dedimax server (Ubuntu 20.04)

[gabrielstuff]

First, thanks for this set of scripts which are really useful.

The php-fpm service won't run until I changed the user in the service configuration.

After a fresh install, I ended up with the following : /lib/systemd/system/php7.4-fpm.service

[Unit]
Description=The PHP 7.4 FastCGI Process Manager
Documentation=man:php-fpm7.4(8)
After=network.target

[Service]
Type=notify
ExecStart=/usr/sbin/php-fpm7.4 --nodaemonize --fpm-config /etc/php/7.4/fpm/php-fpm.conf
ExecStartPost=-/usr/lib/php/php-fpm-socket-helper install /run/php/php-fpm.sock /etc/php/7.4/fpm/pool.d/www.conf 74
ExecStopPost=-/usr/lib/php/php-fpm-socket-helper remove /run/php/php-fpm.sock /etc/php/7.4/fpm/pool.d/www.conf 74
ExecReload=/bin/kill -USR2 $MAINPID

[Install]
WantedBy=multi-user.target

I've added :

User=www-data
Group=www-data

in the [Service] section. Final file looks like:

[Unit]

ExecReload=/bin/kill -USR2 $MAINPID

[Install]
WantedBy=multi-user.target

I do not know if it is intended or not.

Thanks for sharing @gabrielstuff

When you say "fresh" install do you mean you spun up a brand new Ubuntu 20.04 VM in this case? Or do you possibly have other versions of PHP installed already on this machine?

What is the output of service php7.4-fpm status after the failed start?

Did you follow the standard SlickStack ss-install wizard or did you compile any of the packages manually, etc?

Also, did SlickStack properly install/modify your php.ini and php-fpm.conf and www.conf files?

hello and thanks for the quick reply.

"Fresh" like in brand new instance, just installed without anything on it.

The output was something weird that I could not find by googling except in the source code of php-fpm source code:

php-fpm "unable to set priority for the master process"

This appears to be link with root being used by the service because it only tries to setPriority when root user is detected.

As said, after changing the php7.4-fpm.service with the user part, all was fine.

Let me check the file, do you want me to attach them ? how can I make sure they have been correctly created / modified by SlickStack ?

I followed the wizard by running : cd /tmp/ && wget -O ss slick.fyi && bash ss I did not run anything else.

[jessuppi]

I assume perhaps something in PHP-FPM config files did not setup correctly during ss-install and thus the service didn't have the complete users/options to initialize properly.

You can check service php7.4-fpm status output for more info if the service fails.

/etc/php/7.4/fpm/php.ini
/etc/php/7.4/fpm/php-fpm.conf
/etc/php/7.4/fpm/pool.d/www.conf

...these are boilerplates that are downloaded from our mirrors and then modified during ss-install so if you see the PHP-FPM services fails to start you can sudo nano these files and ensure the @placeholders are no longer there... in other words, that these files look like proper configuration files with proper settings/variables.

It all looks clean. Will soon deploy an other slickstack, and will update.

My php-fpm fails to start on reboot each time - recent server of the last week or two, built from scratch, SS_BUILD="DEC2020A"
Was this issue resolved - thjis is after a reboot and PHP failed to start - I had to create the directory /run/php/ before it would start....but issue happens after every reboot and have to redo again.
Is it related to rsync? checking status on rsync shows

root@XXXXXXXXX:~# mkdir /run/php/

Hello.
If you are reboot your system it will fail again. Because the path /run/php isn't exist.
Know anybody why?

Hello.

Know anybody why?

Please mention what cloud network and type of server you are using? What errors do you see during installation?

It is very difficult to diagnose problems without more information...

[linux-brezel]

Hi,

is it possible that this problem only occurs with V-Servers?
........

the system is a Debian 10. I got the same fail messages as the previous.
If I do mkdir /run/php so i can start by command: service php7.4-fpm restart - without any fail messanges.
an by systemctl status php7.2-fpm

If you are use after reboot - mkdir /run/php && service php7.4-fpm start
then it is ok.

For anyone on this thread, SlickStack has only been tested on Ubuntu 20.04 LTS on KVM servers. If you are trying to install on another environment, like Debian, or some container or otherwise, you will likely run into problems...

If you are using un-supported environments, that is complete at-your-own-risk.

[jessuppi]

I have to assume this is caused by faulty packages, possibly vendor-specific (caused by your server provider)... for future Googlers, try purging packages and/or upgrading your entire server and then trying again.

Some combination of package repair/reinstallation/upgrade/reboot it seems...

I saw this happen again recently on OpenVZ server running Ubuntu 20.04. I'm going to reopen this Issue because we are trying to get SlickStack working reliably on OpenVZ servers if possible... stay tuned.
