Vultr

To launch your Vultr instance, follow the steps below.

Step 1: Launching Your Vultr Instance

Logging into Vultr

โ€‹First, go to the Vultr Main Page. If you donโ€™t already have an Vultr account, register one by clicking on "Sign up". Otherwise, log into your Vultr Account by clicking on "Sign in".

Create a new instance

Once logged in, you'll want to add a new instance. Depending on whether your account is new or not, you may or may not have a Products page.

  • If you already have an instance, click the "+" button to deploy a new server. You can also use this link to go to the deploy page.

  • Otherwise, your Products page will be already link you to the Deploy page.

Choose Instance Type

For POSI Chain, two instance types would fit: Cloud Compute and High Frequency.

Select Server Location and Server Type

Choose now your desired server type. We recommend the latest LTS version of Ubuntu (18.04 as of date of now).

Choose Server Size

POSI Chain recommends one of the two following accordingly to the minimum requirements:

Setting Server Name

You can now set the name of your server, e.g. PangaeaNode Then you should click "Deploy Now".

At this point you should be back on the Products page and your server should be installing. However, the setup isn't completely done, as you need to still create a firewall.

Firewall Setup

As we want to allow other nodes to connect to yours, we have to open the correct ports.

Once you are on the Firewall page, click Add Firewall Group.

Enter a name for the firewall group, e.g. FoundationNode.

Open the following 3 ports to the public ("Anywhere" on inbound).

  • TCP 22 (SSH)

  • TCP 6000

  • TCP 9000

Make sure to check that 3 Group Rules have been set.

  1. Click Linked Instances.

  2. Make sure your new server is selected.

  3. Click the + button.

  4. Click Add Linked Instance.

Your instance should now be added to the firewall group and the number of linked instances should increment by 1.

You can now go back to the Products page and your server is now successfully set up!

Step 2: Connecting via SSH to your Instance
