1.7.0

Install Access Gateway on Ubuntu (Bare Metal)

NOTE: Debian-based AGW deployments are no longer supported as of v1.6. If you want to install to Debian, refer to v1.5 of the documentation.

Prerequisites

To set up a Magma Access Gateway, you will need a machine that satisfies the following requirements:

  • AGW_HOST: 64bit-X86 machine, baremetal strongly recommended (not virtualized). You will need two ethernet ports. We use enp1s0 and enp2s0 in this guide.

    • enp1s0: Will carry any traffic that is not S1. So data plane traffic (SGi) control plane traffic (Orc8r HTTP2), management (ssh)
    • enp2s0: S1 interface.

    *Note interface names might have different names on your hardware so just replace enp1s0 and enp2s0 with your current interfaces name in this guideline.

    *Note that the agw_install_ubuntu.sh script will rename the enp1s0 interface to eth0.

    *Note if you don't want all internet traffic to go through enp1s0 to separate control plane (Orc8r Http2 traffic) from user plane, you may want to add another interface and configure proper routing.

Deployment

1. Create boot USB stick and install Ubuntu on your AGW host

  • Download the Ubuntu Server 20.04 LTS .iso image from the Ubuntu website
  • Create bootable usb using etcher tutorial here
  • Boot your AGW host from USB (Press F11 to select boot sequence, :warning: This might be different for your machine). If you see 2 options to boot from USB, select the non-UEFI option.
  • Install and configure you access gateway according to your network defaults.
    • Make sure to enable ssh server and utilities (untick every other)
  • Connect your SGi interface to the internet and select this port during the installation process to get an IP using DHCP.

2. Deploy magma on the AGW_HOST

Run AGW installation

To install on server with DHCP configured SGi interface.

su
wget https://raw.githubusercontent.com/magma/magma/v1.6/lte/gateway/deploy/agw_install_ubuntu.sh
bash agw_install_ubuntu.sh

To Install on server with statically allocated SGi interface. Fow example: SGi has 1.1.1.1/24 IP and upstream router IP is 1.1.1.200

su
wget https://raw.githubusercontent.com/magma/magma/v1.6/lte/gateway/deploy/agw_install_ubuntu.sh
bash agw_install_ubuntu.sh 1.1.1.1/24 1.1.1.200

The script will run a pre-check script that will prompt you what will change on your machine. If you're okay with those changes reply yes and magma will be installed. If no is replied It will stop the installation.

  - Check if Ubuntu is installed
  Ubuntu is installed
  - Check for magma user
  magma user is not Installed
  - Check if both interfaces are named eth0 and eth1
  Interfaces will be renamed to eth0 and eth1
  eth0 will be set to dhcp and eth1 10.0.2.1
  Do you accept those modifications and want to proceed with magma installation?(y/n)
  Please answer yes or no.

The machine will reboot but It's not finished yet, the script is still running in the background. You can follow the output there

journalctl -fu agw_installation

When you see "AGW installation is done." It means that your AGW installation is done, you can make sure magma is running by executing:

service magma@* status

Post Install Check

Make sure you have control_proxy.yml file in directory /var/opt/magma/configs/ before running post install script.

bash /root/agw_post_install_ubuntu.sh
