Install Gluu Flex On Red Hat EL#

This is a step-by-step guide for installation and uninstallation of Gluu Flex on Red Hat Enterprise 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 firewall-cmd --permanent --zone=public --add-service=https

    sudo firewall-cmd --reload;
  • Install EPEL and mod-auth-openidc as dependencies 
    sudo yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-$(rpm -E %rhel).noarch.rpm

    sudo yum -y module enable mod_auth_openidc;
  • 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 
    wget https://github.com/GluuFederation/flex/releases/download/nightly/flex-0.0.0-nightly.el8.x86_64.rpm -P /tmp

  • Go to /tmp directory:

    Command
    cd /tmp

  • Verify the cryptographic signature using cosign (primary verification):

    Note

    Install the cosign CLI if not already installed.

    • Download the cosign bundle from the Releases page:

      Command
      wget https://github.com/GluuFederation/flex/releases/download/nightly/flex_0.0.0-nightly.bundle -P /tmp

    • Verify the signature:

      Command
      cosign verify-blob \
  --bundle flex_0.0.0-nightly.bundle \
  --certificate-identity-regexp "https://github.com/GluuFederation/flex" \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com \
  flex-0.0.0-nightly.el9.x86_64.rpm

      Output similar to below confirms the package was signed by the Janssen CI pipeline:

      Output
      Verified OK

  • Optionally, verify integrity using the published checksum file (secondary check):

    Command
       echo 'paste-release-sha256sum flex-0.0.0-nightly.el9.x86_64.rpm' | sed 's/^sha256://' >flex-0.0.0-nightly.el9.x86_64.rpm.sha256sum && sha256sum -c flex-0.0.0-nightly.el9.x86_64.rpm.sha256sum

    Output similar to below should confirm the integrity of the downloaded package.

    Output
    flex-0.0.0-nightly.el9.x86_64.rpm: OK

Install the Release Package#

sudo yum install ./flex-0.0.0-nightly.el8.x86_64.rpm

Run the setup script#

Execute the setup script with command below: 

sudo python3 /opt/jans/jans-setup/flex/flex-linux-setup/flex_setup.py


Install Admin UI [Y/n]: y

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
    Full TUI documentation can be found here

  • Log into Admin-UI using URI below 

    https://FQDN/admin
    After successful installation of the Admin-UI component, we need to upload the required SSA input as a file path. This should be the SSA or file that was acquired as part of prerequisite step.

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. Update the HTTPS cofiguration file https_jans.conf as shown below:

Note

Want to use Let's Encrypt to get a certificate? Follow this guide.

  • Open https_jans.conf 
    sudo vi /etc/httpd/conf.d/https_jans.conf
  • Update SSLCertificateFile and SSLCertificateKeyFile parameters values 
    SSLCertificateFile location_of_fullchain.pem
SSLCertificateKeyFile location_of_privkey.pem
  • Restart httpd service for changes to take effect 
    sudo service httpd restart

Uninstallation#

Removing Flex is a two step process:

If you have not run the setup script, you can skip step 1 and just remove the package.
