How To Install Composer on openSUSE

In this tutorial, we will show you how to install Composer on openSUSE. In the realm of PHP development, dependency management is a crucial aspect that can significantly streamline your workflow. One tool that has revolutionized this process is Composer. As a robust and reliable dependency manager for PHP, Composer allows developers to declare the libraries their project depends on, and it takes care of installing and updating them.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Composer on openSUSE.

Prerequisites

• A server running one of the following operating systems: openSUSE.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• You will need access to the terminal to execute commands. openSUSE provides the Terminal application for this purpose. It can be found in your Applications menu.
• You’ll need an active internet connection to download Composer and its dependencies.
• You’ll need administrative (root) access or a user account with sudo privileges.

Install Composer on openSUSE

Step 1. Keeping your system packages up-to-date is a good practice. On openSUSE, you can update your system packages by running the command:

sudo zypper refresh
sudo zypper update

This command updates all the packages on your system to their latest versions. If prompted, enter your password and press Y to confirm the update.

Step 2. Installing Necessary PHP Extensions.

Certain PHP extensions are required for Composer to function correctly. For instance, the openssl and phar extensions are crucial. Install these extensions by running:

sudo zypper install php-openssl php-phar

Step 3. Installing Composer on openSUSE.

Once PHP and the necessary extensions are installed, you can proceed to download Composer. The Composer installer can be downloaded from the official website using the wget command:

wget https://getcomposer.org/composer.phar

After downloading Composer, you need to make the file executable and move it to a directory that is in your system’s PATH. This allows you to run Composer from any location on your system. Use the following commands to achieve this:

chmod +x composer.phar
sudo mv composer.phar /usr/local/bin/composer

Finally, verify the installation by checking the installed version of Composer. You can do this by running the following command:

composer --version

If the installation is successful, this command will display the installed version of Composer.

Congratulations! You have successfully installed Composer. Thanks for using this tutorial for installing Composer on your openSUSE system. For additional or useful information, we recommend you check the official Composer website.
