Question

I want to run on Digital Ocean noSQL database, especially, eXist-db. Which droplet should I start with?

I need to run noSQL database, especially, eXist-db so called High-performance native XML database engine available at http://exist-db.org/exist/apps/homepage/index.html on Digital Ocean. I have two questions:

  1. Which droplet should I start with?
  2. What is a monthly price of it?
  3. Is there any instructions on how to install and run noSQL?

Hi there,

I am one of the eXist-db core developers. At the moment there is no official eXist-db Droplet for Digital Ocean.

You likely have 4 main options -

  1. Take a Linux droplet, such as Ubuntu, and install eXist-db and its dependencies as per the eXist-db documentation. I think that is already discussed above.

  2. Take the Docker droplet - https://marketplace.digitalocean.com/apps/docker and then deploy an eXist-db Docker container from https://hub.docker.com/r/existdb/existdb

  3. Use the Digital Ocean Kubernetes solution and deploy an eXist-db Docker container.

  4. Build your own eXist-db droplet for Digital Ocean. This mainly involves step (1) and then repackaging it.

If there is enough interest, we might consider providing an official eXist-db Droplet for Digital Ocean.

Hello,

According to the official eXist-DB documentation, the minimum system requirements are:

  • At least Java version 8 (since eXist-db 3.0)
  • About 200Mb of disk space for the installation
  • At least 512Mb memory to run

This means that you could start with the smallest Droplet at $5 per month and then upgrade if you ever need to.

Regarding the installation, first you would have to install Java, you can follow the steps on how to do that here:

https://www.digitalocean.com/community/tutorials/how-to-install-java-with-apt-on-ubuntu-18-04

After that I would suggest following the steps from the official eXist-db documentation :

  • Download the installer by following the download link on the eXist-db homepage page. We recommend that you download the latest stable release. The installer is a single file called eXist-db-setup-[version].jar (for instance eXist-db-setup-3.6.1.jar).

  • Upload the installer to your droplet

  • Then launch the installer:

java -jar eXist-db-setup-[version].jar
  • You would get an installation command-line interface that you could go through to finish the setup. At the end you should get something like
[ Console installation done ]

Then if you’ve selected the default installation directory you could start the service up with the following:

/usr/local/eXist-db/bin/startup.sh -u admin -p password

Then by default the application would start on port 8080 and port 8443, so if you visit your droplet’s IP followed by the 8080 port you should see the application.

Hope that this helps! Regards, Bobby
