Please note that Amazon Linux now uses Amazon Linux 2, which is the latest version. To install Composer on Amazon Linux 2, follow these steps:

1. Connect to your Amazon Linux 2 instance via SSH.
2. Update the package manager's package list by running the following command: sudo yum update
3. Install the required dependencies by running the following commands: sudo amazon-linux-extras install php7.4 sudo yum install php-cli php-zip unzip
4. Download and install Composer by running the following commands: php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" php composer-setup.php php -r "unlink('composer-setup.php');"
5. Move the Composer executable to a directory in your system's PATH by running the following command: sudo mv composer.phar /usr/local/bin/composer
6. Verify that Composer is installed correctly by running the following command: composer --version

You should now have Composer installed and available for use on your Amazon Linux 2 instance.
