Debian installation

This guide describes the fastest way to install Graylog on Debian Linux 8 (Jessie). All links and packages are present at the time of writing but might need to be updated later on.


This setup should not be done on publicly exposed servers. This guide does not cover security settings!


Not all required dependencies are available in the standard repository, so we need to add Debian Backports to the list of package sources:

$ sudo echo "deb jessie-backports main" > /etc/apt/sources.list.d/backports.list
$ sudo apt-get update

If you’re starting from a minimal server setup, you will need to install these additional packages:

$ sudo apt-get install apt-transport-https openjdk-8-jre-headless uuid-runtime pwgen


The version of MongoDB included in Debian Jessie is recent enough to be used with Graylog 2.0.0 and higher:

$ apt-get install mongodb-server


Graylog 2.0.0 and higher requires Elasticsearch 2.x, so we took the installation instructions from the Elasticsearch installation guide:

$ wget -qO - | sudo apt-key add -
$ echo "deb stable main" | sudo tee -a /etc/apt/sources.list.d/elasticsearch-2.x.list
$ sudo apt-get update && sudo apt-get install elasticsearch

Make sure to modify the Elasticsearch configuration file (/etc/elasticsearch/elasticsearch.yml) and set the cluster name to graylog: graylog

After you have modified the configuration, you can start Elasticsearch:

$ sudo systemctl daemon-reload
$ sudo systemctl enable elasticsearch.service
$ sudo systemctl restart elasticsearch.service


Now install the Graylog repository configuration and Graylog itself with the following commands:

$ wget
$ sudo dpkg -i graylog-2.0-repository_latest.deb
$ sudo apt-get update && sudo apt-get install graylog-server

Follow the instructions in your /etc/graylog/server/server.conf and add password_secret and root_password_sha2. These settings are mandatory and without them, Graylog will not start!

The last step is to enable Graylog during the operating system’s startup:

$ sudo systemctl daemon-reload
$ sudo systemctl enable graylog-server.service
$ sudo systemctl start graylog-server.service


If you’re operating a single-node setup and would like to use HTTPS for the Graylog web interface and the Graylog REST API, it’s possible to use NGINX or Apache as a reverse proxy.


Please file a bug report in the GitHub repository for the operating system packages if you run into any packaging related issues.
