[Bug] - Service Unavailable on docker image

[adelkedjour]

Describe the bug not able to run Apache server with PHP 8.2 using docker image

To Reproduce Steps to reproduce the behavior: Create a docker container using the amazonlinux:2023:

FROM amazonlinux:2023

RUN dnf update -y && dnf upgrade -y && \
    dnf install -y nc gcc-c++ ncurses make gcc make mod_ssl openssh openssl which nano libzip libzip-devel dos2unix \
    httpd php8.2 php-pear php8.2-{devel,common,fpm,mbstring,gd,mysqlnd,bcmath,xml,intl,zip,sodium}

WORKDIR /var/www/html

# Expose the HTTP and HTTPS ports
EXPOSE 80
EXPOSE 443

CMD ["httpd", "-D", "FOREGROUND"]    

Expected behavior I should be able to access to the phpinfo.php that I created, also if I try to switch from php-fpm to php I can't because the apache php_module is not getting installed and it doesn't found at all.

Screenshots

Desktop (please complete the following information):

• OS: Fedora 38
• Browser [firefox, brave, vivaldi]
• Version [e.g. 22]

Additional context Add any other context about the problem here.

@adelkedjour is your container running? Using your Dockerfile it fails to start:

AH00526: Syntax error on line 101 of /etc/httpd/conf.d/ssl.conf:
SSLCertificateFile: file '/etc/pki/tls/certs/localhost.crt' does not exist or is empty

SSLCertificateFile: file '/etc/pki/tls/certs/localhost.crt' does not exist or is empty

I removed some code lines in the dockerfile I shared here. In the original one I do generate the certificate, and the container is up and running.

@adelkedjour If you expect to reach your container via localhost:port from host it won't work unless you specifically publish it at runtime. 0.0.0.0 means any address but 127.0.0.1

[adelkedjour]

@zcobol I have no problem reaching my container via localhost:port from my host machine. As I mentioned, my issue is with php scripts are not working. As you see in the screenshot, html files are working fine and can reach them via localhost:port but php throw the 503 Service Unavailable issue. The apache syntax config is OK, digging more I found that the current default apache use php-fpm and if I try to switch to mod_php all the php scripts return the source code in the browser instead this due the apache php_module missing. I believe this library is completely missing from the docker image or amazon linux 2023 packages repo.

@adelkedjour you need php-fpm service running also.

@adelkedjour you need php-fpm service running also.

That's the problem, it doesn't want to start for example if I run php-fpm -F I got:

[root@a2156192f9c8 ~]# php-fpm -F                        
[14-Mar-2024 19:37:58] ERROR: unable to bind listening socket for address '/run/php-fpm/www.sock': No such file or directory (2)
[14-Mar-2024 19:37:58] ERROR: FPM initialization failed

This my dockerfile:

FROM amazonlinux:2023

RUN dnf update -y && dnf upgrade -y && \
    dnf install -y nc gcc-c++ ncurses make gcc make mod_ssl openssh openssl which nano libzip libzip-devel dos2unix \
    httpd php8.2 php-pear php8.2-{devel,common,fpm,mbstring,gd,mysqlnd,bcmath,xml,intl,zip,sodium}

# Generate SSL certificate
RUN openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/pki/tls/private/localhost.key -out /etc/pki/tls/certs/localhost.crt -subj "/C=GB/ST=London/L=London/O=localhost/OU=localhost/CN=localhost"

WORKDIR /var/www/html

# Expose the HTTP and HTTPS ports
EXPOSE 80
EXPOSE 443

CMD ["httpd", "-D", "FOREGROUND"] 
CMD ["php-fpm", "-F"] 

PS: I tried the docker httpd image worked fine, also the php:8.2-fpm image worked fine and even noticed some difference comparing to amazonlinux:2023 so I am not sure why is not working in AL2023? Any idea why mod_php is not found I can't switch into it as the package doesn't exists at all in the packages repository.

Please could you try it yourself and let me know if you will be able to run it without any issues?

I tried also to create a container without any custom configuration, just I SSH into it and installed httpd and php didn't work tbh!

docker run -it amazonlinux:2023 /bin/bash

[Update]:

@elsaco @zcobol I fixed the issue by creating the /run/php-fpm/ folder manually that's why I was getting this error:

ERROR: unable to bind listening socket for address '/run/php-fpm/www.sock': No such file or directory (2)

Checking if the folder /run/php-fpm/ exists:

[root@8bca94ae883b ~]# ls -al /run/
