Open5GS – CP

Getting MongoDB

Import the public key used by the package management system.

sudo apt update
sudo apt install wget gnupg -y
wget -qO - https://www.mongodb.org/static/pgp/server-6.0.asc | sudo apt-key add -

Create the list file /etc/apt/sources.list.d/mongodb-org-6.0.list for your version of Ubuntu.

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/6.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-6.0.list

Install the MongoDB packages.

sudo apt update 
sudo apt install -y mongodb-org
sudo systemctl start mongod
sudo systemctl enable mongod

Building the WebUI of Open5GS

The WebUI allows you to interactively edit subscriber data. While it is not essential to use this, it makes things easier when you are just starting out on your Open5GS adventure. (A command line tool is available for advanced users).

Node.js is required to install the WebUI of Open5GS

Debian and Ubuntu based Linux distributions can install Node.js as follows:

sudo apt install curl -y
curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
sudo apt install nodejs

You can now install WebUI of Open5GS.

curl -fsSL https://open5gs.org/open5gs/assets/webui/install | sudo -E bash -
