Taking Configuration Snapshots in JBoss EAP

When making changes to a JBoss EAP server configuration, it's often worthwhile to ensure copies of these configurations exist, both to revert to a snapshot should a change fail or simply to save a successful configuration for use on other servers. To do this, we can work with JBoss EAP's native snapshot feature to take, manage, and remove configuration snapshots.

  1. Challenge

    Deploy a Standalone Server Based on the Provided Snapshot

    1. Stop the current JBoss EAP server:

      sudo systemctl stop jboss-eap-rhel

    2. Move into the JBoss EAP home directory:

       cd /opt/jboss-eap

    3. Start a standalone server using the 20191121-201850161standalone.xml snapshot:

       sudo ./bin/standalone.sh --server-config=standalone_xml_history/snapshot/20191121-201850161standalone.xml

    4. Check that you can access the management console at PUBLICIP:9990.

    5. Shut down the server with CTRL+C.

  2. Challenge

    Take a Snapshot of the Current Deployment

    Before replacing the configuration file, we want to take a snapshot of the current configuration located at /opt/jboss-eap/standalone/configuration/standalone.xml just in case something fails.

    Note: This is the configuration used by our service and the one used in the /opt/jboss/bin/standalone.sh script, unless we override it as we did in the previous task.

    1. Restart the JBoss service:

      sudo systemctl start jboss-eap-rhel

    2. Open the JBoss CLI:

      sudo ./bin/jboss-cli.sh

    3. Connect to the server:

      connect

    4. Take a snapshot of the current configuration:

      :take-snapshot

    5. Exit the CLI:

      exit

  3. Challenge

    Replace the Standalone Configuration

    1. We know the 20191121-201850161standalone.xml configuration is the one we wish to use. Since we know our jboss-eap-rhel service relies on /opt/jboss-eap/standalone/configuration/standalone.xml, we can just copy our snapshot there:

      sudo cp standalone/configuration/standalone_xml_history/snapshot/20191121-201850161standalone.xml standalone/configuration/standalone.xml

    2. Restart the service:

      sudo systemctl restart jboss-eap-rhel

    3. Confirm you can access the management console.

  4. Challenge

    Delete the Old Snapshot

    1. Access the JBoss CLI:

      sudo ./bin/jboss-cli.sh

    2. Connect to the server:

      connect

    3. List the available snapshots:

      :list-snapshots

    4. Remove the backup snapshot of the failing configuration:

      :delete-snapshot(name=20191122-133032735standalone.xml)

    5. Exit the CLI:

      exit
