5G Standalone Core Network Slicing

Installation

1. Open5GS 5G Core Installation

I) Getting MongoDB

1. Import the public key used by the package management system:

   sudo apt update
   sudo apt install gnupg
   curl -fsSL https://pgp.mongodb.com/server-6.0.asc | sudo gpg -o /usr/share/keyrings/mongodb-server-6.0.gpg --dearmor

2. Add the MongoDB repository:

   echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-6.0.gpg] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/6.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-6.0.list
   sudo apt update

3. Install MongoDB:

   sudo apt install -y mongodb-org

4. Start MongoDB (if /usr/bin/mongod is not running):

   sudo systemctl start mongod

5. Ensure MongoDB starts automatically on system boot:

   sudo systemctl enable mongod

II) Install Open5GS

1. Add the Open5GS repository:

   sudo add-apt-repository ppa:open5gs/latest
   sudo apt update

2. Install Open5GS:

   sudo apt install open5gs

III) Install the WebUI of Open5GS

1. Download and import the NodeSource GPG key:

   sudo apt update
   sudo apt install -y ca-certificates curl gnupg
   sudo mkdir -p /etc/apt/keyrings
   curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg

2. Create the Node.js repository:

   export NODE_MAJOR=20
   echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_$NODE_MAJOR.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list

3. Update and install Node.js:

   sudo apt update
   sudo apt install nodejs -y

4. Install the Open5GS WebUI:

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