Issue
When I list files as a root user:
root@complect-shop:~# ls -lah /www/server/php/73/var/log/
total 5.8M
drw-r----- 2 root www 4.0K Oct 8 10:00 .
drwxr-xr-x 4 root root 4.0K Dec 16 2019 ..
-rw-r----- 1 root www 1.5M Jan 7 12:48 php-fpm.log
-rw-r----- 1 root www 4.3M Jan 6 07:12 slow.log
root@complect-shop:~#
php-fpm.log file has access read an write for root user and read for www group.
Here is the error for user web which is in www group:
╭╴web@complect-shop ~/complect-import-stock-wc
╰╴16:41:03 $ tail /www/server/php/73/var/log/php-fpm.log
tail: cannot open '/www/server/php/73/var/log/php-fpm.log' for reading: Permission denied
Here is a proof user is in the www group:
╭╴web@complect-shop ~/complect-import-stock-wc
╰╴16:45:05 $ groups web
web : web www-data www
Solution
The file php-fpm.log will need write access as it is a log file and so allocate wrirte access to the www group
sudo chmod g+w /www/server/php/73/var/log/php-fpm.log
