In this article, we will learn how to install Composer PHP dependency manager CentOS 7.
Composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.
Composer is not a package manager in the same sense as Yum or Apt are. Yes, it deals with "packages” or libraries, but it manages them on a per-project basis, installing them in a directory (e.g. vendor) inside your project. By default it does not install anything globally. Thus, it is a dependency manager. It does however support a "global” project for convenience via the global command.
To install Composer, we need to follow some simple steps.
1. Keep the server up-to-date
# yum -y update
2. Change working directory
# cd /usr/local/src
3. Now, install Composer by using cURL
# curl -sS https://getcomposer.org/installer | php
We have successfully install Composer.
To use Composer globally composer.phar to /usr/local/bin/ using following command.
# mv -f composer.phar /usr/local/bin/composer
Verify the Composer is working using following command:
# composer -V
If you want to run Composer via different PHP version, use PHP bin path with Composer path. As shown below:
# /usr/local/bin/php /usr/local/bin/composer command
All selectors php bin path can be found in /opt/alt
# /opt/alt/php73/usr/bin/php /usr/local/bin/composer command
