Install Gluu Flex On Ubuntu Linux#

This is a step-by-step guide for installation and uninstallation of Gluu Flex on Ubuntu Linux

Prerequisites#

  • Ensure that the OS platform is one of the supported versions
  • VM should meet VM system requirements
  • Make sure that if SELinux is installed then it is put into permissive mode
  • If the server firewall is running, make sure you allow https, which is needed for OpenID and FIDO. 
    sudo ufw allow https
  • Please obtain an SSA to trial Flex, after which you are issued a JWT that you can use during installation. SSA should be stored in a text file on an accessible path.

Install the Package#

Download and Verify the Release Package#

  • Download the release package from the GitHub FLEX Releases. Choose the correct command from below based on the OS version. 

    #Ubuntu 22.04
wget https://github.com/GluuFederation/flex/releases/download/vreplace-flex-version/flex_replace-flex-version.ubuntu22.04_amd64.deb -P /tmp

    #Ubuntu 20.04
wget https://github.com/GluuFederation/flex/releases/download/vreplace-flex-version/flex_replace-flex-version.ubuntu20.04_amd64.deb -P /tmp

  • GPG key is used to ensure the authenticity of the downloaded package during the installation process. If the key is not found, the installation step would fail. Use the commands below to download and import the GPG key. 

    wget https://github.com/GluuFederation/flex/files/11814579/automation-flex-public-gpg.zip

    unzip automation-flex-public-gpg.zip;

    sudo gpg --import automation-flex-public-gpg.asc;

  • Verify the integrity of the downloaded package using published sha256sum. Download the sha256sum file for the package. Choose the correct command from below based on the OS version. 

    #Ubuntu 22.04
wget https://github.com/GluuFederation/flex/releases/download/vreplace-flex-version/flex_replace-flex-version.ubuntu22.04_amd64.deb.sha256sum  -P /tmp

    #Ubuntu 20.04
wget https://github.com/GluuFederation/flex/releases/download/vreplace-flex-version/flex_replace-flex-version.ubuntu20.04_amd64.deb.sha256sum  -P /tmp
    Verify package integrity of the package that has been downloaded by checking hash. Run the command below from the directory where the downloaded package and the .sha256sum files are located. Choose the correct command from below based on the OS version. 
    #Ubuntu 22.04
cd /tmp
sha256sum -c flex_replace-flex-version.ubuntu22.04_amd64.deb.sha256sum

    #Ubuntu 20.04
cd /tmp
sha256sum -c flex_replace-flex-version.ubuntu20.04_amd64.deb.sha256sum
    Output similar to below should confirm the integrity of the downloaded package. 
    flex_replace-flex-version.ubuntu<version>_amd64.deb: ok

Install the Release Package#

Choose the correct command from below based on the OS version.

#Ubuntu 22.04
apt install -y /tmp/flex_replace-flex-version.ubuntu22.04_amd64.deb

#Ubuntu 20.04
apt install -y /tmp/flex_replace-flex-version.ubuntu20.04_amd64.deb

Run the setup script#

Execute the setup script with command below: 

sudo python3 /opt/jans/jans-setup/flex/flex-linux-setup/flex_setup.py
If Admin-UI component is being installed, then the script will require SSA input, either as text or as a file path. This should be the SSA or file which was acquired as part of prerequisite step. 
Install Admin UI [Y/n]: y
Please enter path of file containing SSA or paste SSA (q to exit):
Alternatively, for SSA file can be passed as a parameter to the setup script as below. 
sudo python3 /opt/jans/jans-setup/flex/flex-linux-setup/flex_setup.py -admin-ui-ssa [filename]

Verify and Access the Installation#

Verify that installation has been successful and all installed components are accessible using the steps below:

  • Log in to Text User Interface (TUI) 

    /opt/jans/jans-cli/jans_cli_tui.py
    TUI is a text-based configuration tool for Gluu Flex Server.

  • Log into Admin-UI using URI below 

    https://FQDN/admin

When troubleshooting issues with Admin UI access, it's advisable to check the logs, refer to the FAQ, and review service dependencies for potential solutions.

  • Access Casa using URI below 
    https://FQDN/jans-casa

Enabling HTTPS#

To enable communication with Janssen Server over TLS (https) in a production environment, Janssen Server needs details about CA certificate.
