What is the difference between shared hosting and VPS?
It is the same difference as between a dedicated server and usual shared hosting.

With a VPS, you receive all the power of dedicated hosting with the ability to have your own set of services and customizable disk space. With shared hosting, you have limited administrative access and can’t customize software configurations, while with a VPS you can perform any actions from your control panel and don’t need to contact technical support with every single request.

How to install Composer on shared servers

How to install Composer on shared servers

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 will never install anything globally. Thus, it is a dependency manager.

To install Composer:

1. SSH access should be enabled for your hosting account with us. Follow the steps provided in this article to switch SSH access on.

2. To access your account via SSH, download and install one of the available SSH clients. You can find the list of free SSH clients here. In case you are using a Unix-based OS (Linux or OSX), you can easily run the Terminal application and connect to the server using the command:

ssh username@servername -pPORT

ssh – command for logging into the remote server
username – your cPanel username
servername– name of the server where your hosting account is located (you can find it using this tutorial)
PORT – connection port – 21098 for a Shared Hosting servers, 22 – for a VPS/Dedicated server 

3. Open your SSH client, put your domain name or the IP address of the server into the Host Name field, enter 21098 or 22 into the Port field, choose SSH as your connection type and press the Open button:
