I’ve inherited a WordPress 5.7 site running on an Ubuntu 16.04.3 x64 droplet, which uses a separate DigitalOcean managed MySQL 8 database.
The WordPress site is a Trellis LEMP stack site. PHP version 7.3, but Nginx seems to be using 7.1 from a phpinfo().
I’m aware that all the versions are seriously outdated and need updating, but in the very immediate term I need to first get things working.
There was a database connection error (see https://www.digitalocean.com/community/questions/since-a-wordpress-url-change-i-can-t-connect-to-do-managed-mysql-database) and this involved me trying a lot of unwise things until now the deployment to the staging site via Trellis fails.
Here’s what it says:
TASK [deploy : Reload php-fpm]

If I SSH in and try to start the service I get

with error code. See "systemctl status php7.3-fpm.service" and
"journalctl -xe" for details.
Here’s systemctl status php7.3-fpm.service:

And I am stuck. I’m not very confident in a Linux environment so I’m completely lost to be honest. I figure I need to fix this before I fix my database connection error!
I did try to add PHP 7.4, but this generated several pages of red errors when I tried to deploy the site so I removed it.
This is a staging site, so it’s not critical, but obviously the production site has the same background setup to I’m terrified it will break too!
In the longer term I plan to upgrade everything but would really like some help trying to get it working in the immediate short-term.
Thanks!
>Solution :
It clearly says that php-fpm7.3 fails to start because ERROR: Another FPM instance seems to already. You probably have php-fpm7.1 already running.
