In this tutorial, we will show you how to install and configuration of PHP Composer on your CentOS 7 server. For those of you who didn’t know, PHP Composer is a powerful dependency management tool that has become an essential part of modern PHP development. It allows developers to easily manage and install third-party libraries and packages, making it simpler to build complex applications.
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. I will show you the step-by-step installation of PHP Composer on the CentOS 7 server.
Prerequisites
- A server running one of the following operating systems: CentOS 7.
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- SSH access to the server (or just open Terminal if you’re on a desktop).
- A
non-root sudo user
or access to theroot user
. We recommend acting as anon-root sudo user
, however, as you can harm your system if you’re not careful when acting as the root.
Install PHP Composer on CentOS 7
Step 1. It’s always a good practice to keep your system up-to-date. Run the following command to update all installed packages:
yum -y update
This command will fetch the latest package updates from the CentOS repositories and install them on your system.
Step 2. Installing Required Dependencies.
Composer requires several dependencies to function properly. Install them using the following command:
sudo yum install php-cli php-mbstring git curl unzip
Next, check if PHP 7 is installed, run the following command in your terminal:
php -v
If the output shows a version lower than 7, you’ll need to install PHP 7. You can do this by running:
sudo yum install epel-release sudo yum install php php-cli php-common php-devel php-mbstring php-pdo php-gd php-mysqlnd
Step 3. Installing Composer on CentOS 7.
Download and install Composer by executing the following command:
curl -sS https://getcomposer.org/installer | php
Sample result:
[root@idroot ~]# curl -sS https://getcomposer.org/installer | php #!/usr/bin/env php Some settings on your machine may cause stability issues with Composer. If you encounter issues, try to change the following: Your PHP (5.3.3) is quite old, upgrading to PHP 5.3.4 or higher is recommended. Composer works with 5.3.2+ for most people, but there might be edge case issues. Downloading... Composer successfully installed to: /root/composer.phar Use it: php composer.phar
Once the process completes, you can make the ‘composer.phar
’ file executable by running the following command:
chmod +x composer.phar
Now use the following commands to make composer available globally for all users in your system, which can be used for all PHP applications on that system:
mv composer.phar /usr/local/bin/composer
You can also check the version of the composer by running the command:
composer -V
The output of the command should be similar to this:
Composer version 1.0-dev (7a9eb02190d334513e99a479510f87eed18cf958) 2015-9-08 10:46:33
