NOTE: It is recommended to install UNMS on a server, with a public IP address and FQDN, which is directly connected to the main gateway of the network. In this setup, UNMS will automatically have a valid certificate, it will report outages in the most precise manner and all of its advanced functions will perform optimally. It is certainly possible to place UNMS server in a different spot in a topology, but there may be some limitations involved.

Installation Instructions

Run the command below on the host to install and start UNMS (it will automatically install Docker if it is not installed already). If a UNMS installation already exists, it will be overwritten, but all data will be kept. It is possible to use the attribute--update if the new installation needs to have the same parameters as the old one.  Registering new devices to UNMS can be done by following the steps in this article: The UNMS Key and the Device Registration Process. If it is necessary to customize the installation process, please read Optional installation steps.

curl -fsSL https://unms.com/v1/install > /tmp/unms_inst.sh && sudo bash /tmp/unms_inst.sh

The installation script will check if ports :80 and :443 are open and if they are not, it will ask which ports should UNMS to use. The same applies to the overcommit memory settings. If the vm.overcommit_memory is not set to '1', the installation script asks for permission to do it. In case those interrupts are unwanted in the installation process it is possible to suppress them with --unattended attribute to let the installation script do all the necessary arrangements by itself.

When the process is complete, UNMS is accessible at http://server_hostname_or_ip/. Please don't use localhost. Use server hostname or its IP address.

NOTE: The installation script needs to use sudo permissions. Those are required to install Docker in case it is not available in the OS already. It is also needed to create the UNMS user, under which the UNMS application runs as well as to set up a cron task that manages the UNMS updates.
