Install PHP Composer via Jelastic SSH Gateway

The instruction below enables to install PHP Composer - a popular dependency management tool - via Jelastic SSH Gateway. It involves a few adjustments that allow to execute Composer from any working directory on a server without having to write out its full path.

Note: In order to run the Composer installation by means of  Jelastic SSH Gateway, you need to:

Once you’ve established SSH connection to your Apache PHP or NGINX PHP server (Apache 2.4 in our example), you can easily integrate Composer into your project. So, let’s see how to download and run this tool.

Tip: You can also execute the Composer installation through Jelastic dashboard UI.

Install Composer

The steps below show how to install Composer and perform its configuration, that will enable us to execute it from any working directory throughout a server. 

1. Run the Composer installer from inside your server working directory to download the appropriate composer.phar archive:

curl -sS https://getcomposer.org/installer | php

curl get composer

2. Rename the composer.phar file to just “composer” and move it to the private bin directory with the below commands:

mkdir ~/bin
mv ~/composer.phar ~/bin/composer

composer commands

3. Now, let’s add Composer to the server PATH variable in order to be able to further execute it from any server directory. In such a way, you won’t have to write out the full path (i.e. /var/www/bin/composer) for calling this dependencies manager when necessary.

For that, run one of the following commands depending on used application server:
  • for Apache PHP:
    export PATH=$PATH:/var/www/bin
    echo 'export PATH=$PATH:/var/www/bin' >> ~/.bashrc

    composer path apache

  • for NGINX PHP:
    export PATH=$PATH:/var/lib/nginx/bin
    echo 'export PATH=$PATH:/var/lib/nginx/bin' >> ~/.bashrc

    composer path nginx

That's it! Composer is added to your PATH variable now.

4. Everything is already set up! You can run the following command in order to ensure that PHP Composer works as intended:

composer about

composer about

Great! Now you can freely use Composer on your Apache or NGINX server and manage dependencies within your PHP projects.
