Elastic Virtual Private Server on Top of CentOS

centos virtual private serverCentOS stands for Community ENTerprise Operating System, that is a completely free and community-driven project, with open source code delivered from RHEL Linux distribution. CentOS offers enterprise-grade stability, enhanced with consistent performance, which are achieved through continuous community contribution. As a result, CentOS represents a reliable, low-maintenance and secure option for running virtual private servers.

CentOS VPS Cloud Hosting

To effortlessly set up your own CentOS Elastic VPS inside the Cloud, log in to your Jelastic account and access environment topology wizard.

install centos vps

The appropriate instance (i.e. CentOS 6.8 or CentOS 7.2) can be found within the expandable options list upon enabling VPS block at the bottom left wizard corner (for the detailed installation guidance, refer to the VPS Configuration page).

Note: By default, VPS node is delivered with the automatically attached Public IP address (one per each instance if the server is scaled).
Jelastic provides a set of inbuilt tools for applying some basic settings to your VPS instance right via dashboard UI. For more complicated configs, you’ll need to access it via SSH - this can be accomplished in one of the following ways:

CentOS VPS Access via SSH Gate

To get the most out of your CentOS virtual machine and apply configurations with the full root permissions, you’ll need to access it using SSH protocol. The easiest way to accomplish this is to establish connection via Jelastic SSH Gate with the help of your terminal.

terminal window

It allows to securely connect to entire Jelastic account and manage all your environments and containers via a single access point.

ssh access remote server

To navigate through the lists, just type the option index number and press Enter.

ssh access centos vps

Once inside the required CentOS VPS container, you can start applying the necessary configurations as a root user.

To access your account via Jelastic SSH Gate, you need to preliminary perform the following steps:

CentOS VPS Access via Public IP

It is also possible to access your VPS container by means of any preferred SSH software via the attached Public IP address. In this case, the same root privileges are granted as whilst working via Jelastic SSH Gate.

Note: You can locate your node Public IP address within email, delivered upon environment creation, or at the dashboard via the Additionally list for the required node.

centos public ip

To establish secure connection to the target container, launch the preferred SSH software (OpenSSH in our example).

Then initiate the connection using your server administration data, i.e. username and IP address, by executing the ssh {username}@{hostname} string (you’ve received this data via email beforehand).

centos vps ssh access

Confirm your identity with the appropriate password and start working with your CentOS virtual machine as a root user.

Tip: To get more details on how to establish connection via Public IP based on the OS that is run on your local machine, refer to the linked guide.

Web-Based CentOS SSH Client

One more way to operate your CentOS virtual private server is to connect to it by means of a special web-based SSH client. It operates yum dependencies manager to skillfully maintain packages within your server and is available right through the Jelastic dashboard.

Note: This tool is available only for CentOS VPS with Public IP address attached.

1. Click on the Open in browser button next to the required CentOS container at the dashboard.

centos ssh console

2. In the opened Console, confirm your identity by inserting the administrator password - it was sent to you via email upon environment setup (use the Copy and Paste buttons at the top panel).

Upon successful authentication, you can start applying the required configurations by means of executing the corresponding yum commands (e.g. yum install, yum remove, yum update, etc).
