![]() Next, update your apt sources with sudo apt-get update, and then install the RethinkDB package with sudo apt-get install rethinkdb. To actually install RethinkDB, you'll need to add the RethinkDB Personal Package Archive (PPA) with the command sudo add-apt-repository ppa:rethinkdb/ppa 6. You should be taken to the console for your freshly launched Ubuntu instance. Go ahead and SSH into it with either the root password emailed to you or with your SSH key if you've selected that option. Once your instance is launched, you're taken to a screen containing your server's IP address. ![]() After you've selected all of the options you'd like to use, click the large "Create Droplet" button at the bottom of the screen. If you wish to use an SSH key for authentication (which is highly recommended), select which key you'd like preinstalled on your Droplet. For now, "Ubuntu 13.10 圆4" or "Ubuntu 13.04 圆4" are good choices unless you have another preference. Enter a hostname, choose an instance size 4, select the region closest to you 5 for the lowest latency, and choose an operating system. This is enough to run a 512 MB droplet for two months, or a 1 GB RAM droplet for a single month 2.Īfter registering, log into your account and create a new droplet 3 on the dashboard.

In this tutorial, we'll go over how to properly setup a RethinkDB node and configure iptables to secure access to the database and web administration interface on DigitalOcean specifically, however this tutorial applies to any VPS or Dedicated Server provider. However, this doesn't mean that DigitalOcean is a bad host for your RethinkDB database- especially if you're looking to try out the database or if you're just running a single node (which is fine for many different applications). There are ways around this, such as running a VPN (especially a mesh VPN like tinc) or manually adding each RethinkDB's IP address to your iptables rules, but this is a much more complicated setup than using another host that has proper security groups. Essentially, this would allow any DigitalOcean VPS in the data center to attach itself to your RethinkDB cluster, which is less than ideal.īecause of this, DigitalOcean is not a great host to run a cluster on if you're looking to get up and running quickly. ![]() Unlike Amazon's security groups, which allow you to restrict traffic between specific instances, every DigitalOcean VPS can talk to each other over the private network 1. The one issue is, they currently do not provide any easy way of securing clusters of RethinkDB instances. Essentially, this means that if you have an exposed installation of RethinkDB, anyone can join your database cluster and run arbitrary queries.ĭigitalOcean, a great startup VPS provider, is a cheap means of trying out RethinkDB for yourself. For example, RethinkDB's web administration interface is completely unsecured when exposed to the public Internet, and the clustering port does not have any authentication mechanisms. One major issue still remains with RethinkDB, however- it's relatively difficult to secure properly unless you have security group or virtual network functionality from your hosting provider (a la Amazon Web Services Virtual Private Cloud, security groups, etc.). Though the database is relatively new, it has been funded and is moving quickly to add new features and a Long Term Support release. RethinkDB also features functionality such as map-reduce, sharding, multi-datacenter functionality, and distributed queries. RethinkDB is a distributed document-store database that is focused on easy of administration and clustering.
