Classic OSM Build
From OSM Public Wiki
Install the classic build from binaries
Although the Classic Build of OSM does not bring significant new features as compared to Release THREE (it has been tagged as R3.1), it can still be installed from OSM Relelease FOUR installer.
To install the latest OSM classic build from source, requirements are the following:
- 8 CPUs, 16 GB RAM, 100GB disk and a single interface with Internet access
- Ubuntu16.04 (64-bit variant required) as base image (http://releases.ubuntu.com/16.04/), configured to run LXD containers. If you don't have LXD configured, you can follow the instructions here (LXD configuration).
Once you have prepared the host with the previous requirements, all you need to do is:
wget https://osm-download.etsi.org/ftp/osm-4.0-four/install_osm.sh chmod +x install_osm.sh ./install_osm.sh --soui
Other considerations regarding LXD install and connectivity may apply as in Release THREE (provided that the --soui flag is added).
