ArangoDB - System Requirements

In this chapter, we will discuss the system requirements for ArangoDB.

The system requirements for ArangoDB are as follows −

A VPS Server with Ubuntu Installation

RAM: 1 GB; CPU : 2.2 GHz

For all the commands in this tutorial, we have used an instance of Ubuntu 16.04 (xenial) of RAM 1GB with one cpu having a processing power 2.2 GHz. And all the arangosh commands in this tutorial were tested for the ArangoDB version 3.1.27.

How to Install ArangoDB?

In this section, we will see how to install ArangoDB. ArangoDB comes pre-built for many operating systems and distributions. For more details, please refer to the ArangoDB documentation. As already mentioned, for this tutorial we will use Ubuntu 16.04x64.

The first step is to download the pubpc key for its repositories −

# wget https://www.arangodb.com/repositories/arangodb31/
xUbuntu_16.04/Release.key

Output

The important point is that you should see the Release.key saved at the end of the output.

Let us install the saved key using the following pne of code −

# sudo apt-key add Release.key

Output

OK

Run the following commands to add the apt repository and update the index −

# sudo apt-add-repository  deb
https://www.arangodb.com/repositories/arangodb31/xUbuntu_16.04/ / 
# sudo apt-get update

As a final step, we can install ArangoDB −

# sudo apt-get install arangodb3

Output
