Trying to confirm is php7.0-fpm is working with apache on Ubuntu 16.04

php-fpmubuntu-16.04

I configured php7.0-fpm to work with apache on Ubuntu 16.04 but not sure if it is correctly configured and working.

As I understand, after installation and configuration, the output of php info file should display "Server API –> FPM/FastCGI" but it is still showing "Server API –> Apache 2.0 Handler".

This is how I installed and configured php7.0-fpm:

sudo apt-get install libapache2-mod-fastcgi php7.0-fpm

sudo a2enmod actions fastcgi alias

sudo a2enconf php7.0-fpm

sudo service php7.0-fpm restart

sudo systemctl status php7.0-fpm

sudo systemctl restart apache2.service

Below is the output of sudo systemctl status php7.0-fpm:

What am I doing wrong? Would appreciate some help and advice?

Below is the contents of my /etc/apache2/conf-enabled/php7.0-fpm.conf file:

<Directory /usr/lib/cgi-bin>
    Require all granted
</Directory>
<IfModule mod_fastcgi.c>
    AddHandler php7-fcgi .php 
    Action php7-fcgi /php7-fcgi
    Alias /php7-fcgi /usr/lib/cgi-bin/php7-fcgi
    FastCgiExternalServer /usr/lib/cgi-bin/php7-fcgi -socket /var/run/php/php7.0-fpm.sock -pass-header Authorization
</IfModule>

You need to enable the proxy_fcgi module, and disable mod_php7, for the stock php7.0-fpm conf file to be effective.

If you look at /etc/apache2/conf-enabled/php7.0-fpm.conf, you'll see this at the top:

<IfModule !mod_php7.c>
<IfModule proxy_fcgi_module>

I think your max_children is too low

<value name="max_children">3</value>

Also you can try switching from TCP port to unix socket for php-fpm:

php-fpm.conf

<value name="listen_address">/tmp/php.sock</value>

nginx.conf

fastcgi_pass unix:/tmp/php.sock;

Elaborated:

Unix sockets are ~20% faster
You don't use time-wait sockets for each connect

The secret here is that php-cgi is nto a real file, it's a wrong file name use internally in Apache. You could call it as well : false-php-cgi-catcher-which-do-not-exists.

I wrote a complete php-fpm+apache2.2+chroot install guide a few days ago here. You may have a look. But try to get it working without the chroot first. Note that starting with apache 2.3 the best tool for php-fpm will be mod_proxy_fcgi

Here's an extract of the complete install guide. I use php5.external where you want to use php-cgi.

# phpfpm/fastcgi
# Here we catch the 'false' Location used to inexistent php5.external
# and push it to the external FastCgi process via a socket
# note: socket path is relative to FastCgiIpcDir
# which is set in Main configuration /etc/apache2/mods-available/fastcgi.conf
<IfModule mod_fastcgi.c>
    # all .php files will be pushed to a php5-fcgi handler
    AddHandler php5-fcgi .php

    #action module will let us run a cgi script based on handler php5-fcgi
    Action php5-fcgi /fcgi-bin/php5.external

    # and we add an Alias to the fcgi location
    Alias /fcgi-bin/php5.external /php5.external

    # now we catch this cgi script which in fact does not exists on filesystem
    # we catch it on the url (Location)
    <Location /fcgi-bin/php5.external>
        # here we prevent direct access to this Location url,
        # env=REDIRECT_STATUS will let us use this fcgi-bin url
        # only after an internal redirect (by Action upper)
        Order Deny,Allow
        Deny from All
        Allow from env=REDIRECT_STATUS
    </Location>
</IfModule>
FastCgiExternalServer /php5.external -socket myapplication.sock -appConnTimeout 30 -idle-timeout 60
