How to Install dependencies from RedHat Software Collections on RHEL 7

On a Red Hat Enterprise Linux (RHEL7) installation, the default PHP version available in the official repository is 5.4. However, API Portal only supports PHP 7.1.X-7.4.X. You can use RedHat Software Collections (RHSCL) to install PHP 7.1.X-7.4.X.

Enable RedHat Software Collections

Before installing Apache HTTP server and PHP you must first enable RHSCL:

sudo subscription-manager repos --enable rhel-server-rhscl-7-rpms
sudo yum clean all

Install Apache HTTP server on RHEL7

1. Install Apache from RHSCL:
   

   sudo yum install httpd24-httpd httpd24-httpd-tools httpd24-mod_ssl

2. Verify the /usr/bin/httpd directory does not exist. If it does, rename it and run:
   

   sudo ln -s <span class="pl-s"><span class="pl-pds">$(</span>which httpd<span class="pl-pds">)</span></span> /usr/bin/httpd

3. Make Apache available in any bash session by default:
   

   <span class="pl-c1">echo</span> <span class="pl-s"><span class="pl-pds">"</span>source scl_source enable httpd24<span class="pl-pds">"</span></span> <span class="pl-k">|</span> sudo tee -a /etc/profile.d/scl-httpd24.sh
   <span class="pl-c1">source</span> /etc/profile.d/scl-httpd24.sh
   sudo ln -s <span class="pl-s"><span class="pl-pds">$(</span>which httpd<span class="pl-pds">)</span></span> /usr/bin/httpd

4. Verify Apache is now available:
   

   httpd -v

5. Enable and start Apache service:
   

   sudo systemctl <span class="pl-c1">enable</span> --now httpd24-httpd

6. Verify that Apache service is active and running:
   

   systemctl status httpd24-httpd

You must install the latest PHP version provided by the RHSCL.

1. Install all required PHP packages:
   

   sudo yum install rh-php73 rh-php73-php rh-php73-php-cli rh-php73-php-common rh-php73-php-gd rh-php73-php-json rh-php73-php-intl rh-php73-php-mbstring rh-php73-php-mysqlnd rh-php73-php-pdo rh-php73-php-xml rh-php73-php-zip

2. Verify the /usr/bin/httpd directory does not exist. If it does, rename it and run:
   

   sudo ln -s <span class="pl-s"><span class="pl-pds">$(</span>which httpd<span class="pl-pds">)</span></span> /usr/bin/httpd

3. Enable PHP in bash:
   

   <span class="pl-c1">echo</span> <span class="pl-s"><span class="pl-pds">"</span>source scl_source enable rh-php73<span class="pl-pds">"</span></span> <span class="pl-k">|</span> sudo tee -a /etc/profile.d/scl-rh-php73.sh
   <span class="pl-c1">source</span> /etc/profile.d/scl-rh-php73.sh
   sudo ln -s <span class="pl-s"><span class="pl-pds">$(</span>which php<span class="pl-pds">)</span></span> /usr/bin/php

   If /usr/bin/php already exists, please rename it and execute again

   sudo ln -s <span class="pl-s"><span class="pl-pds">$(</span>which php<span class="pl-pds">)</span></span> /usr/bin/php

4. Verify that PHP is available:
   

   php -v

5. Verify that php7_module is enabled in Apache:
   

   httpd -M <span class="pl-k">|</span> grep php7

1. Restart Apache and verify it is running:
   

   sudo systemctl restart httpd24-httpd
   systemctl status httpd24-httpd
