How do I install PECL 7 modules on Elastic Beanstalk environments using the PHP 8.1 with Amazon Linux 2 platform branch?

Short description

To install PECL 7 modules, you must create a configuration file (.ebextension) that includes commands to:

• Install dependencies
• Install the PECL module
• Create or modify configuration files

Resolution

Complete the following steps:

1. Set up the .ebextensions directory in the root of the source bundle of your application. For example:

   |-- .ebextensions
   |        |-- redis/memcached.config
   |        |-- other .config files
   |-- other application files

   For more information, see Advanced environment customization with configuration files (.ebextensions) and Extending Elastic Beanstalk Linux platforms.
   Note: All configuration files are stored in the .ebextensions folder. The Elastic Beanstalk environment uses only files that end with the .config extension.

2. In the .ebextensions directory, create a configuration file that includes the following commands for your module.

   For Redis modules

   commands:
     01_install_redis:
       command: /usr/bin/yes 'no' | /usr/bin/pecl install redis
       test: '! /usr/bin/pecl info redis'
     02_remove_extension:
       command: /bin/sed -i -e '/extension="redis.so"/d' /etc/php.ini
     03_create_conf:
       command: /bin/echo 'extension="redis.so"' > /etc/php.d/41-redis.ini

   The Redis configuration file does the following:
   Installs the Redis module and tests for installation success (01_install_redis).
   Removes the Redis extension from the /etc/php.ini file (02_remove_extension).
   Creates a configuration file with the name 41-redis.ini at /etc/php.d/ (03_create_conf).

   For Memcached modules

   packages:
     yum:
       libmemcached-devel: []
   commands:
     01_install_memcached:
       command: /usr/bin/yes 'no'| /usr/bin/pecl install memcached
       test: '! /usr/bin/pecl info memcached'
     02_remove_extension:
       command: /bin/sed -i -e '/extension="memcached.so"/d' /etc/php.ini
     03_create_conf:
       command: /bin/echo 'extension="memcached.so"' > /etc/php.d/41-memcached.ini

   The Memcached configuration file does the following:
   Installs the Memcached module and tests for installation success (01_install_memcached).
   Removes the Redis extension from the /etc/php.ini file (02_remove_extension).
   Creates a configuration file called 41-memcached.ini at /etc/php.d/ (03_create_conf).

   Note: Always test a new .ebextension before adding to a production environment.
