The article walks you through installing ArangoDB on Debian 11 in a few easy steps and getting it running within minutes. It starts by updating your system, importing the official GPG key, adding the stable repository, and then installing both the server and client packages before enabling the daemon to start at boot. Once the service is verified as active you can launch the web UI on localhost 8529, set an administrator password, and run a quick sanity check that creates a test collection, inserts a document, and confirms the count. For production environments it recommends optional hardening steps such as binding only to 127.0.0.1 and enabling TLS with custom certificates so the database stays secure.

Install ArangoDB on Debian 11 in Minutes

If you’re running a fresh Debian 11 machine and want a multi‑model database that can handle documents, graphs, and key/value pairs, ArangoDB is the right choice. This guide gets you past the “how do I even start?” stage straight to the web UI where you’ll be creating collections like a pro.

1: Make sure your system is up‑to‑date

sudo apt update && sudo apt upgrade -y

Why bother? Debian’s security patches are a moving target; an outdated kernel or libstdc++ can bite you later when ArangoDB pulls in newer libraries. Updating first keeps the install smoother.

2: Import the ArangoDB GPG key

curl -fsSL https://download.arangodb.com/arangodb3/DEBIAN/GPG-KEY-ARANGODB | sudo gpg --dearmor -o /usr/share/keyrings/arango.gpg

The key tells apt that the packages come from a trustworthy source. Without it, you’ll get “NO_PUBKEY” errors and be forced to skip the repository.

3: Add the official Debian repository

echo "deb [signed-by=/usr/share/keyrings/arango.gpg] https://download.arangodb.com/arangodb3/DEBIAN/ stable main" | sudo tee /etc/apt/sources.list.d/arango.list > /dev/null

I’ve seen this happen after a bad driver update: the package list gets corrupted, and apt can’t resolve the repo URL. Adding it back fixes that.

4: Install ArangoDB

sudo apt update
sudo apt install arangodb3-server arangodb3-client

The arangodb3-server package pulls in everything you need to run the daemon, while arangodb3-client gives you the command‑line tools. If you only care about the UI, this is still the minimal set.

5: Start and enable the service

sudo systemctl start arangod
sudo systemctl enable arangod

Enabling makes sure ArangoDB starts automatically after a reboot—no more manual arangod launches. Starting it now verifies that dependencies like Java are in place.

6: Check the service status

sudo systemctl status arangod | grep Active

If you see “active (running)”, congratulations! If not, the log (/var/log/arangodb3/server.log) is your best friend. A common hiccup is missing libssl on older Debian releases; installing libssl1.1 fixes it.

7: Open the web UI

Navigate to < http://localhost:8529> in your browser. The first time you hit it, you’ll be prompted to set an administrator password—do that now and remember it.

8: Quick sanity check with a query

arangosh -c "db._create('test'); db.test.insert({foo:'bar'}); db.test.count();"

If the command returns 1, you’re good to go. If it complains about “database not found”, double‑check that the service is running.

9: Optional – Tighten security for production

• Disable HTTP on all interfaces: edit /etc/arangodb3/arangod.conf and set bind-address = 127.0.0.1.
• Enable TLS by generating a certificate and pointing tls.key-file / tls.cert-file.

I once ran into a client that kept crashing because the server was listening on all NICs, letting traffic flood in. Locking it down saved me a lot of headaches.

That’s everything you need to get ArangoDB up and running on Debian 11. Now go create some collections, write queries, or just marvel at how easy it was.
