Graylog 2 – Debian 8
This guide describes the fastest way to install Graylog on Debian Linux 9 (Stretch). 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!
If you’re starting from a minimal server setup, you will need to install these additional packages:
The version of MongoDB included in Debian Jessie is recent enough to be used with Graylog 2.3.x and higher:

The last step is to enable Graylog during the operating system’s startup:
Multiple Server Setup
If you plan to have multiple server taking care of different roles in your cluster like we have in this big production setup you need to modify only a few settings. This is covered in our Multi-node Setup guide. The default file location guide will give you the file you need to modify in your setup.
