如果更改操作系统，如何更新arangodb

Question

I installed arangodb on Ubuntu 14.04 LTS, after that, I upgrade my ubuntu to 15.10 and soon will upgrade it to 16.04 LTS, what should I do to my arangodb? Should I re-install based on my Ubuntu version, or there is some workaround to do?

Thank you, Elmer

Since ArangoDB offers all releases across recent Ubuntu versions, (we need gcc 4.9 at least to build the releases) you should be able to update/upgrade ArangoDB at a different pace than your OS. Means:

• Follow the ArangoDB Blog where we anounce releases including the changes and bugfixes.
• keep up with the latest released ArangoDB for your Ubuntu release
• Once a new Ubuntu is released, update the OS, and install the ArangoDB package for your new OS which should in term be the same release as you had before.

You should be able to achieve this by simply properly configuring your apt sources.list; You first download and add the Signature key to your packaging system:

wget https://www.arangodb.com/repositories/arangodb2/xUbuntu_14.10/Release.key
apt-key add - < Release.key

Use apt-get to install arangodb:

echo 'deb https://www.arangodb.com/repositories/arangodb2/xUbuntu_14.10/ /' |\
    sudo tee /etc/apt/sources.list.d/arangodb.list
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install arangodb=2.8.7

Once you do the upgrade to 15.10, you edit /etc/apt/sources.list.d/arangodb.list and change the ubuntu release to 15.10, and run

sudo apt-get update
sudo apt-get install arangodb=2.8.7

to get the package for the new OS release.
