PHP FPM and HTTP configuration

UNIX for Advanced & Expert Users

I have to configure PHP to work together with HTTPD.
I have compared configuration of files from other servers already configured with PHP and HTTPD.
This is the output when I grep the fpm service (on the working server) :

[root@www2b aigini]# ps -ef | grep fpm
root      3561     1  0 Jan16 ?        00:08:28 php-fpm: master process (/etc/opt/rh/rh-php71/php-fpm.conf)

root     12201 12075  0 16:53 pts/0    00:00:00 grep --color=auto fpm
[root@www2b aigini]#

In my server, when I grep fpm, I get this :

[root@login.int.myassist.my php-fpm.d]#ps -ef | grep fpm
root      6690     1  0 16:32 ?        00:00:00 php-fpm: master process (/etc/opt/rh/rh-php71/php-fpm.conf)

[root@login.int.myassist.my php-fpm.d]#

These are all the php related packages I installed in the server :

How and what do I have to configure in my server to make the output as the working server?

as far as I can see your new box is ready to serve PHP from within the HTTPd server -- provided

You have php-fpm package installed for your server -- which is a YES from your list of php packages.

just place a file in /var/www/html/ like feeka.php and try browsing it?
use this code

echo "<?php echo phpinfo(); ?>" > /var/www/html/feeka.php

then try browsing the page in your browser with http://IP_OF_YOUR_MACHINE/feeka.php

or do a curl
curl http://IP_OF_YOUR_MACHINE/feeka.php

this should given your an output which will set your direction for next steps.

The number of php-fpm process should differ from server to server and from second to second, since it is load & configuration dependent.
ps and counting will not get you far.

Compare configuration files /etc/opt/rh/rh-php71/php-fpm.conf from both boxes using diff or similar utility.
Check for min/max parameters and pm=<value> especially.

Read about php-fpm to understand the values and behavior.

Hope that helps

Yes, thk you all for your replies.
As long as you got httpd running, and you start php-fpm, you will be able to see the list of pools matching the number of httpd processes.
However, of course you have to configure files like php-fpm.conf, www.conf, and create a symlink between /usr/local/httpd and /opt/rh/httpd24/root/etc/httpd.
We also create phpfpm.conf in this symlink to complete the php configuration.
