directive 'catch_workers_output = yes' don't work as I want

Question

I have CentOS 7 with apache 2.4.35 with pmp event and php-fpm

all works fine but all php errors are go to one big file for all my virtual hosts.

I read all docs about it and find that

catch_workers_output = yes

might be help me. I think that this directive send all php errors to apache log file but there is no luck.

I don't really know what I should now.

here is my php.conf

<Proxy "unix:/var/run/php-fpm/default.sock|fcgi://php-fpm">
 # we must declare a parameter in here (doesn't matter which) or it'll not register the proxy ahead of time
 ProxySet disablereuse=off
</Proxy>
# Redirect to the proxy
<FilesMatch \.php$>
    SetHandler proxy:fcgi://php-fpm
</FilesMatch>

#
# Allow php to handle Multiviews
#
AddType text/html .php
#
# Add index.php to the list of files that will be served as directory
# indexes.
#
DirectoryIndex index.php

ProxyErrorOverride on

p.s. I think that individual pool per site will solve the problem but I think that it get really more memory, because every pool need to create empty slots to start serving...

Answer 1

I found that if I comment out this line in file /etc/php-fpm.d/www.conf

php_admin_value[error_log] = /var/log/php-fpm/www-error.log

like here:

;php_admin_value[error_log] = /var/log/php-fpm/www-error.log

all php errors go to the apache log files (individual per site)

There is no need to touch catch_workers_output . Leave it commented out!

;catch_workers_output = no
