Run PHP application in Apache server using PHP-FPM - php

Question

We have a php application which was running fine using
Docker Image :
php:7.2-apache-stretch
We now have to make use of the below image for better performance and make the application work as it was before .
php:7.2.17-fpm-stretch
As this image does not have apache in it . I updated the Dockerfile starting from the installation of apache2 and related packages based on various forums .
There is many other steps . I have just added the instructions which I have updated in the Dockerfile.
FROM php:7.2.17-fpm-stretch
RUN apt-get update && apt-get install -y apache2 wget
RUN cd /tmp && wget http://mirrors.kernel.org/ubuntu/pool/multiverse/liba/libapache-mod-fastcgi/libapache2-mod-fastcgi_2.4.7~0910052141-1.2_amd64.deb && dpkg -i libapache2-mod-fastcgi_2.4.7~0910052141-1.2_amd64.deb;apt-get install -f
RUN a2enmod actions proxy_fcgi fastcgi
COPY 000-default.conf /etc/apache2/sites-available/000-default.conf
COPY info.php /var/www/html/info.php
COPY run.sh /app/run.sh
# EXPOSE 9000
RUN chmod 755 /app/run.sh
CMD "/app/run.sh"
The info.php contains <?php phpinfo( ); ?> . In the run.sh script , we start the php-fpm service and apache2 as below
php-fpm -D
/usr/sbin/apachectl -D FOREGROUND
previously I was trying to access the app from the port which was mapped to 9000 ( fpm ) . When I accessed the correct port where apache was running , I was able to view info.php .
The Content in the vhost.conf file.
<FilesMatch \.php$>
SetHandler "proxy:fcgi://localhost:9000"
</FilesMatch>

Answer 1

I got it working making a few modifications.
I used this slightly modified dockerfile:
FROM php:7.2.17-fpm-stretch
RUN apt-get update; apt-get install -y apache2 wget
RUN cd /tmp && wget http://mirrors.kernel.org/ubuntu/pool/multiverse/liba/libapache-mod-fastcgi/libapache2-mod-fastcgi_2.4.7~0910052141-1.2_amd64.deb && dpkg -i libapache2-mod-fastcgi_2.4.7~0910052141-1.2_amd64.deb;apt-get install -f
RUN a2enmod actions proxy_fcgi fastcgi
COPY run.sh /app/run.sh
RUN chmod 755 /app/run.sh
CMD "/app/run.sh"
I also added the following snippet (the same modification you did) to /etc/apache2/sites-available/000-default.conf:
<FilesMatch \.php$>
SetHandler "proxy:fcgi://localhost:9000"
</FilesMatch>
Here is the output I get:
[09-Apr-2019 21:23:06] NOTICE: fpm is running, pid 9
[09-Apr-2019 21:23:06] NOTICE: ready to handle connections
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message
Also, did you try building the dockerfile without the cache? Sometimes, caching can cause issues with package installation (see here for more details). To do a clean build of an image, just use:
docker build --no-cache

I got your new configuration working using this dockerfile:
FROM php:7.2.17-fpm-stretch
RUN apt-get update && apt-get install -y apache2 wget
RUN cd /tmp && wget http://mirrors.kernel.org/ubuntu/pool/multiverse/liba/libapache-mod-fastcgi/libapache2-mod-fastcgi_2.4.7~0910052141-1.2_amd64.deb && dpkg -i libapache2-mod-fastcgi_2.4.7~0910052141-1.2_amd64.deb;apt-get install -f
RUN a2enmod actions proxy_fcgi fastcgi
COPY 000-default.conf /etc/apache2/sites-available/000-default.conf
COPY info.php /var/www/html/info.php
COPY run.sh /app/run.sh
RUN chmod 755 /app/run.sh
EXPOSE 80
CMD "/app/run.sh"
The command I ran was:
docker run -P -d --rm <php-image>
The exposed ports are:
0.0.0.0:32773->80/tcp, 0.0.0.0:32772->9000/tcp
I was able to access info.php using http://localhost:32773/info.php

Answer 3

I was able to access the php page . Everything was working fine . But I was looking in the wrong direction . When I run the container .
docker run -P -d --rm php:test-fpm
The output was
82071c9ff023 php:test-fpm "docker-php-entrypoi…" 2 seconds ago Up 1 second 0.0.0.0:32778->80/tcp, 0.0.0.0:32777->9000/tcp practical_mclean
I was accessing localhost:32777/info.php . But I should I accessed the 32778 where apache is exposed and localhost: 32778/info.php worked !!! .
Is there a way to avoid the port mapping of 9000. ???
