This article briefly outlines the basic steps necessary to install and run Memgraph on Ubuntu.
Newer versions of Memgraph are currently not backward compatible with older versions. That is why you won't be able to load storage snapshots between different versions.
Before you proceed with the installation guide make sure that you have:
- The latest Memgraph Ubuntu Package which can be downloaded from the Memgraph download hub.
Memgraph packages are available for:
- Ubuntu 18.04
- Ubuntu 20.04
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:
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.
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
To shut down the Memgraph server, issue the following command:
sudo systemctl stop memgraph
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

To learn how to query the database, take a look at the
querying guide or Memgraph
Playground for interactive tutorials.
Visit the Building applications page if you need to connect to the database programmatically.
