Installation guide

Download Memgraph Ubuntu Package

Downloaded the latest Memgraph Ubuntu Package from the Memgraph Download Hub (opens in a new tab).

You can also use direct download links to get the latest Memgraph packages.

Install Memgraph

After downloading Memgraph as an Ubuntu package, install it by running the following:

sudo dpkg -i /path-to/memgraph_<version>.deb

Why use sudo?

In order to perform some actions on your operating system like installing new software, you may need superuser privileges (commonly called root).

Troubleshooting

Unable to install the Memgraph package with dpkg

While running the following dpkg command:

dpkg -i /path-to/memgraph_<version>.deb

you may encounter errors that resemble the following:

dpkg: error processing package memgraph (--install): dependency problems -
leaving unconfigured Errors were encountered while processing: memgraph

These errors indicate that you don’t have all of the necessary dependencies installed. To install the missing dependencies and finish the installation, issue the following command:

sudo apt-get install -f

Verify that Memgraph is running

To verify that Memgraph is running, run the following:

sudo journalctl --unit memgraph

If successful, you should receive an output similar to the following:

You are running Memgraph vX.X.X

If the Memgraph database instance is not running, you can start it explicitly:

sudo systemctl start memgraph

If you want the Memgraph database instance to start automatically on each startup, run the following command:

systemctl enable memgraph

You can also check the status of the Memgraph database instance by running:

sudo systemctl status memgraph
