Install Memgraph on Ubuntu

This article briefly outlines the basic steps necessary to install and run Memgraph on Ubuntu.

Prerequisites

Before you proceed with the installation guide make sure that you have:

• Downloaded the latest Memgraph Debian Package which can be found here.

Installation guide

After downloading Memgraph as a Debian 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). 

Potential installation error

You could get errors while installing the package with the above command if you don't have all of Memgraph's dependencies installed. The issues mostly look like the following:

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

To install missing dependencies and finish the installation of the Memgraph package, just issue the following command:

sudo apt-get install -f

The above command will install all missing dependencies and will finish configuring the Memgraph package.

On successful installation, Memgraph should already be running. To confirm it, you can start it explicitly as follows:

sudo systemctl start memgraph

To verify that Memgraph is running, run the following:

sudo journalctl --unit memgraph

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

Apr 08 06:16:23 Going-Merry systemd[1]: Started Memgraph: High performance, in-memory, transactional graph>
Apr 08 06:16:23 Going-Merry memgraph[459969]: You are running Memgraph v1.4.0-community

At this point, Memgraph is ready for you to submit queries.

Configuration

The Memgraph configuration is available in /etc/memgraph/memgraph.conf. If the configuration file is altered, Memgraph needs to be restarted. To learn about all the configuration options, check out the Reference guide.

Stopping Memgraph

To shut down the Memgraph server, issue the following command:

sudo systemctl stop memgraph
