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 16.04×64.
The first step is to download the public key for its repositories −
# wget https://www.arangodb.com/repositories/arangodb31/ xUbuntu_16.04/Release.key
Output
--2017-09-03 12:13:24-- https://www.arangodb.com/repositories/arangodb31/xUbuntu_16.04/Release.key Resolving (www.arangodb.com)... 104.25.1 64.21, 104.25.165.21, 2400:cb00:2048:1::6819:a415, ... Connecting to (www.arangodb.com)|104.25. 164.21|:443... connected. HTTP request sent, awaiting response... 200 OK Length: 3924 (3.8K) [application/pgpkeys] Saving to: ‘Release.key’ Release.key 100%[===================>] 3.83K - .-KB/s in 0.001s 2017-09-03 12:13:25 (2.61 MB/s) - ‘Release.key’ saved [39 24/3924]
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 line 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

Done The following package was automatically installed and is no longer required: grub-pc-bin Use ''sudo apt autoremove'' to remove it. The following NEW packages will be installed: arangodb3 0 upgraded, 1 newly installed, 0 to remove and 17 not upgraded. Need to get 55.6 MB of archives. After this operation, 343 MB of additional disk space will be used.
Press Enter. Now the process of installing ArangoDB will start −
