Server Update🔗

Before you install Modelon Impact, it is highly recommended that you update your server with all the latest patches. The installer will not do this for you in case you might want to be in control of the patch level of your server.

If you'd like to update your server, run these commands:

$ sudo apt-get update
$ sudo apt-get upgrade

Download Modelon Impact🔗

You will find all released versions on of Modelon Impact on our Github page. Download the desired version to your home directory on Linux. Then, unpack the archive file (replacing RELEASE with the actual file name) to /var/impact.

$ sudo mkdir /var/impact
$ sudo tar zxfv RELEASE.tar.gz -C /var/impact

Install Modelon Impact🔗

Installing Modelon Impact as 'root' or a Regular User?🔗

These instructions assume that you are installing Modelon Impact as regular user with sudo rights or the root user.

We recommend that you run /var/impact/modelonimpact.sh as your regular user and without sudo in front of it. The script will ask for your password for the tasks that require elevated access rights.

The script modelonimpact.sh will not let you run certain functions as a regular user without sudo rights.

Operating System Environment🔗

The script modelonimpact.sh will prepare the operating system environment for Modelon Impact.

$ /var/impact/modelonimpact.sh

The admin script will install all the required software and configure your environment so you can run Modelon Impact. If anything is missing, the script will resolve it for you.

The first time you run the script, you will be asked to install the required software packages. If you get the following message, write “YES” to have them installed for you.

The following software prerequisites are needed to use this script and install Modelon Impact:

 * curl
 * net-tools
 * bind9-dnsutils
 * bsdmainutils
 * Docker and Docker Compose
 * jq

Write YES to install the software now, or press ENTER to exit: YES

After the required software has been installed, you should logout and login to the shell, as several environment variables will have been changed.

Run the script again, to check the remaining prerequisites:

$ /var/impact/modelonimpact.sh

This time, it will make sure all permissions are correct, then exit to make sure your shell environment is correct:

$ /var/impact/modelonimpact.sh
 __  __           _      _               ___                            _   
|  \/  | ___   __| | ___| | ___  _ __   |_ _|_ __ ___  _ __   __ _  ___| |_ 
| |\/| |/ _ \ / _` |/ _ \ |/ _ \| '_ \   | || '_ ` _ \| '_ \ / _` |/ __| __|

                                                      |_|
               Accurate Simulations. Better Decisions.

Please enter the password for "impactuser" to run with elevated access rights, if asked for it.

Some required permissions are missing, we will have to correct this first.

Adding user impactuser to group docker

To pick up this new group membership, you will have to, either
 - if you are on Ubuntu Desktop: reboot the server.
 - if you are on Ubuntu Server: log out and in again

Please rerun this command when you're back.

Alternatively, you can run the command 'su -l impactuser' to get a shell with the correct environment.

The script creates the group docker and adds your user to the group. The directories under /etc/impact will be created and made accessible to the docker group.
