Deploying GreenRADIUS on Ubuntu 20

Prerequisites

An Ubuntu 20 server versioned 20.04 or greater
Ensure the network interface is configured with a static IP, netmask, gateway, and DNS
The update package for GreenRADIUS 5.1.6.6 or later

Steps

Log in as a user with sudo access.
Run sudo apt-get update
Run sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
Run curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
Run sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
Run sudo apt-get install docker-ce docker-ce-cli containerd.io
Run sudo curl -L "https://github.com/docker/compose/releases/download/1.28.2/docker-compose-Linux-x86_64" -o /usr/local/bin/docker-compose
Run sudo chmod +x /usr/local/bin/docker-compose
Run sudo apt-get install unzip incron net-tools
Run sudo adduser gradmin
Run sudo adduser gradmin sudo
Run sudo chmod -R 750 /home/gradmin
Run sudo chown -R gradmin:gradmin /home/gradmin
Reboot and log in as the gradmin user.
Run sudo su
Run mkdir ~/temp
Run cd ~/temp
Copy the GreenRADIUS update package to the /home/gradmin/temp directory of the Ubuntu instance.
For the following commands, replace xxxx with the version number of the GreenRADIUS updte package:
Run sudo unzip GreenRADIUS_xxxx_Update.zip
Run sudo tar -xvzf GreenRADIUS_xxxx_Update/images.tgz -C .
Run sudo tar -xvzf GreenRADIUS_xxxx_Update/others.tgz -C .
Run sudo mkdir -p /opt/grs/scripts
Run sudo cp others/vm_incron_scripts/* /opt/grs/scripts/
Run cd /opt/grs/scripts && sudo chown root:root *.sh && sudo chmod 511 freeradius_restart.sh get_host_info.sh incron_script.sh openldap_cmd_template_3.sh openldap_restart.sh openldap_update_ca_certificates.sh rsyslog_restart.sh && cd -
Run sudo bash -c "echo 'gradmin ALL=(root) NOPASSWD:/opt/grs/scripts/get_host_info.sh , /opt/grs/scripts/incron_script.sh , /opt/grs/scripts/rsyslog_restart.sh , /opt/grs/scripts/freeradius_restart.sh , /opt/grs/scripts/openldap_restart.sh , /opt/grs/scripts/openldap_update_ca_certificates.sh , /opt/grs/scripts/openldap_cmd_template_3.sh' > /etc/sudoers.d/grs"
Run sudo mkdir -p /opt/grs/host-comm/request
Run sudo mkdir -p /opt/grs/host-comm/response
Run sudo chown -R gradmin:gradmin /opt/grs/host-comm
Run sudo bash -c "echo 'gradmin' > /etc/incron.allow"
Run sudo bash -c "echo '/opt/grs/host-comm/request IN_CLOSE_WRITE sudo /opt/grs/scripts/incron_script.sh \$#' > /var/spool/incron/gradmin"
Run sudo service incron restart
Run sudo docker load -i images/greenradius_xxxx_init_image
Run sudo docker load -i images/greenradius_xxxx_main_image
Run sudo docker load -i images/greenradius_xxxx_openldap_image
Run sudo docker load -i images/greenradius_xxxx_postgres_image
Run sudo docker load -i images/greenradius_xxxx_rsyslog_image
Run sudo docker load -i images/greenradius_xxxx_freeradius_image
Run sudo docker load -i images/greenradius_xxxx_grs_auth_app_image
Run sudo mkdir -p /home/gradmin/grs-docker-compose
Run sudo cp others/docker-compose.yml /home/gradmin/grs-docker-compose/
Run cd /home/gradmin/grs-docker-compose
Run sudo docker-compose up -d
Once the previous step completes, the web administration console should be visible if you navigate to the server's IP address or hostname in your browser. Keep in mind that GreenRADIUS does not serve HTTP for security reasons; if you are getting Connection Refused errors, make sure the scheme is set to HTTPS.
Run sudo touch /etc/systemd/system/grs-docker-compose-app.service
