VPS Configuration

All of the supported virtual private server types at CirrusGrid (i.e. based on CentOS, Ubuntu, and Windows) share the similar installation flow and the main management options. So, to get your Elastic VPS hosted and configured inside the CirrusGrid PaaS, follow the next instructions on how to:

Elastic VPS Installation #

To set up your VPS inside the CirrusGrid PaaS, follow the next steps.

1. Click the New Environment button at the top pane to access environment topology wizard.

2. Herein, click on the VPS section at the bottom left corner and choose the needed VPS (CentOS 7.2 in our example) from the expandable options list.elastic vps topology wizard

Note: When enabling VPS of any type, you’ll automatically get the Public IP address(es) attached to the corresponding node (one per instance).
Nevertheless, in case of strict necessity, you can contact your hosting provider and request the option of running VPS with the internal IP only (e.g. when a special application infrastructure, which is partially inaccessible from outside, is required).

Specify cloudlet limits for this node, scale it out (if required), select the preferred region (if several of them are available), type the name of the environment and click on Create.

3. In a couple of minutes, your new environment with the chosen virtual server will appear at the dashboard. You’ll also receive an email notification with its administration data (i.e. login/password credentials, attached Public IP and access URL).elastic vps reset password button

Also, you can view the Public IP address directly in the dashboard. If you’ve lost access to your VPS server or want to change the admin credentials for it, click the Reset Password button as it is shown in the image above.

Elastic VPS Scaling #

The flexibility of VPS hosting in CirruGrid PaaS is achieved due to automatic scaling, both vertical and horizontal, that is easily tuned during environment topology creation and configuration.

Automatic vertical scaling is ensured by systems ability to provide the required resources due to load. Herewith, you can choose the scalability limits for your server, which prevents outages during unexpected load spikes and at the optimize hosting costs.

To scale your environment, you need to increase/decrease the maximum number of available resources (cloudlets) by adjusting the cloudlet sliders in the Vertical Scaling per Node section.

CirrusGrid horizontal scaling functionality allows to easily adjust the number of servers in your environment using the appropriate “” and “+” buttons. Herewith, you can select the preferred scaling mode:

  • Stateless – simultaneously creates all new nodes from the base image template
  • Stateful – sequentially copies file system of the master container into the new nodes

Make sure to Apply changes you’ve made.

Elastic VPS Inbuilt Tools #

Most of the basic configurations on your VPS instance can be performed directly via dashboard UI with a set of inbuilt tools, provided by CirrusGrid.

Tip: The configurations on the Windows VPS can be applied via the RDP connection only.

File Manager #

The in-built configuration file manager is designed to manage (create/delete, upload/download, edit) files inside your container, as well as setup mount points and manage exported data.elastic vps file manager

The appropriate tab can be opened by clicking on the Config button next to the necessary VPS node (or the whole layer).

Log Files #

Logs tracking is a useful option for the efficient management of your VPS. Here, data on all aspects of your container(s) lifecycle is gathered, which may come in handy while troubleshooting and debugging your applications and services.elastic vps log files

The appropriate section can be accessed by clicking on the Log button next to the necessary VPS node (or the whole layer).

For the complex configurations, you should connect to VPS server over CirrusGrid SSH Gate (including an option to continue working via the dashboard using Web SSH) or establish a direct SSH connection using Public IP.
