[CentOS] Troubleshooting php-fpm with apache on Centos 7
Hello,
I am running httpd-2.4.6-45.el7.centos.x86_64 with
php-fpm-7.0.22-1.el7.remi.x86_64 (on CentOS 7).
My main problem: On this httpd server I have several vhosts running, but
apparently I am facing intermittent problems with php-fpm communication
on only one of them.
Most of the sites are WordPress or Joomla Applications (running with
mysql). Everything seems right: low load, all websites are operating
fine, except this one, but only intermittently.
The secondary problem is that I can't seem to be able to log php errors.
When the problem starts, the users receive "503 Service Unavailable"
pages for many hours/days, and in the error log I see only such errors:

The problem is NOT resolved by restarting apache and/or php-fpm.
The config of the vhost is as follows:
<VirtualHost *:80>
DocumentRoot "/var/webs/wwwgreekgeo/www"
ServerName www.greekgeo.noa.gr
ServerAdmin webmaster at noa.gr
DirectoryIndex index.php index.html index.htm

</VirtualHost>
As you can see, I have made efforts to enable php debugging, but I still
can't see any php logging, in any php log:
/var/log/php-fpm/error.log
/var/log/php-fpm/www-error.log
The file: /var/webs/wwwgreekgeo/log/php_error_log remains empty
I've also followed these directions to enable Wordpress php logging:
https://codex.wordpress.org/WP_DEBUG but I didn't get any php logging
either.
Please advise: How can I enable full php logging and troubleshoot php on
this vhost?
Also: What would you advise, if possible, on the particular problem (php
processing hanging on this vhost only without any obvious reason)?
I've googled and tried many things for several hours, but I can't find a
solution.
Thanks in advance,
Nick
