Upgrade the portal

Edge for Private Cloud v4.18.05

This procedure describes how to upgrade an existing Apigee Developer Services portal (or simply, the portal) on-premise installation.

Determining the correct update procedure

The procedure that you use to update the portal is based on your current installation:

Determining your current installation type

If you are unsure about your current installation type, use the following command to determine it:

  • ls /opt

    If you are using Nginx/Postgres, you will see the following directories: /opt/apigee and /opt/nginx.

    If you are using Apache/MySQL or Apache/MariaDB, then these directories should not be present.

  • /opt/apigee/apigee-service/bin/apigee-all status

    If you are using Nginx/Postgres, you will see the following output:

    + apigee-service
    apigee-drupal-devportal status
    OK: apigee-drupal-devportal is up and running
    + apigee-service apigee-lb status
    apigee-service: apigee-lb: OK
    + apigee-service apigee-postgresql status
    apigee-service: apigee-postgresql: OK
  • apachectl -S

    If you are using Apache/MySQL or Apache/MariaDB, then this command should return the web root directory of the portal, in the form:

    *:80
    192.168.56.102 (/etc/httpd/conf/vhosts/devportal.conf:1)

Default installation directory

The upgrade process assumes that the portal was installed at:

  • 4.17.05 and later: /opt/apigee/apigee-drupal/wwwroot
  • Prior to 4.17.05: /opt/apigee/apigee-drupal (Nginx) or /var/www/html (Apache)

If you did not install the portal in the default directory, modify the paths in the procedure below to use your installation directory.

Supported upgrade versions

This upgrade procedure is supported for the following versions of the portal:

  • OPDK-17-01.x
  • OPDK-17-05.x
  • OPDK-17-09.x
  • OPDK-18-01.x

To determine your portal version, open the following URL in a browser:

http://yourportal.com/buildInfo

Before you update

For existing installations, if you have modified any code in Drupal core or in any non-custom modules, your modifications will be overwritten. This includes, among other things, any changes you may have made to .htaccess. You should assume that anything outside the /sites directory is owned by Drupal. An exception to this rule is robots.txt; if this file exists in the web root, it will be preserved for you.

Before proceeding with the installation, make a backup of your entire Drupal web root directory. After performing the installation steps described below, you can restore your customizations from the backup.

Upgrading a portal using RPMs

To update the portal RPM on a node:

  1. Change to the Drupal directory, /opt/apigee/apigee-drupal by default:
    cd /opt/apigee/apigee-drupal
  2. Backup your Drupal database instance. The pg_dump command creates a copy of the database:
    pg_dump --dbname=devportal --host=host_IP_address --username=drupaladmin
      --password --format=c > /tmp/portal.dmp

    where:

    • devportal is the database name as specified by the PG_NAME property in the portal installation configuration file.
    • host_IP_address is the IP address of the portal node.
    • drupaladmin is the Postgres username used by the portal to access the database as specified by the DRUPAL_PG_USER property in the portal installation configuration file.
    • You are prompted for the Postgres user password as defined by the DRUPAL_PG_PASS property in the portal installation configuration file.

    If you later have to restore from the backup, use the command:

    pg_restore --clean --dbname=devportal --host=localhost  --username=apigee < /tmp/portal.dmp
  3. Make a backup of your entire Drupal web root directory. The default install location is /opt/apigee/apigee-drupal, but you might have changed it.

    If you are unsure of the location of this directory, use the drush status command or the Configuration > Media > File entry in the Drupal menu to determine the location of the public file system and private file system path (for the next step).

  4. Make a backup of the files in /opt/apigee/data/apigee-drupal-devportal/private.
  5. Set Drupal to maintenance mode:
    1. Select Configuration in the Drupal menu.
    2. On the Configuration page, select Maintenance mode under Development.
    3. Select the Put site into maintenance mode box.
    4. Enter a message users see during maintenance.
    5. Select Save configuration.
  6. Disable SELinux as described in Install the Edge apigee-setup utility.
  7. Change to the /opt directory:
    cd /opt
  8. For an upgrade on a server with an Internet connection:
    1. Download the Edge 4.18.05 bootstrap_4.18.05.sh file to /tmp/bootstrap_4.18.05.sh:
      curl https://software.apigee.com/bootstrap_4.18.05.sh -o /tmp/bootstrap_4.18.05.sh
    2. Install the Edge 4.18.05 apigee-service utility and dependencies:
      sudo bash /tmp/bootstrap_4.18.05.sh apigeeuser=uName apigeepassword=pWord

      Where uName and pWord are the username and password you received from Apigee. If you omit pWord, you will be prompted to enter it.

      By default, the installer checks to see that you have Java 1.8 installed. You can use the "C" option to continue without installing Java.

  9. For an upgrade on a server with no Internet connection:
    1. Create a local 4.18.05 repo as described in Create a local Apigee repository.
    2. To install apigee-service from a .tar file:
      1. On the node with the local repo, use the following command to package the local repo into a single .tar file named /opt/apigee/data/apigee-mirror/apigee-4.18.05.tar.gz:
        /opt/apigee/apigee-service/bin/apigee-service apigee-mirror package
      2. Copy the .tar file to the node where you want to update Edge. For example, copy it to the /tmp directory on the new node.
      3. On the new node, untar the file to the /tmp directory:
        tar -xzf apigee-4.18.05.tar.gz

        This command creates a new directory, named repos, in the directory containing the .tar file. For example /tmp/repos.

      4. Install the Edge apigee-service utility and dependencies from /tmp/repos:
        sudo bash /tmp/repos/bootstrap_4.18.05.sh apigeeprotocol="file://" apigeerepobasepath=/tmp/repos

        Notice that you include the path to the repos directory in this command.

    3. To install apigee-service using the Nginx webserver:
      1. Configure the Nginx web server as described in "Install from the repo using the Nginx webserver" at Install the Edge apigee-setup utility.
      2. On the remote node, download the Edge bootstrap_4.18.05.sh file to /tmp/bootstrap_4.18.05.sh:
        /usr/bin/curl http://uName:pWord@remoteRepo:3939/bootstrap_4.18.05.sh
          -o /tmp/bootstrap_4.18.05.sh

        Where uName and pWord are the username and password you set above for the repo, and remoteRepo is the IP address or DNS name of the repo node.

      3. On the remote node, install the Edge apigee-service utility and dependencies:
        sudo bash /tmp/bootstrap_4.18.05.sh apigeerepohost=remoteRepo:3939
          apigeeuser=uName apigeepassword=pWord apigeeprotocol=http://

        Where uName and pWord are the repo username and password.

  10. Use apigee-service to update the apigee-setup utility:
    /opt/apigee/apigee-service/bin/apigee-service apigee-setup update
  11. Run the update utility on your Postgre node:
    /opt/apigee/apigee-setup/bin/update.sh -c ps -f configFile

    Where configFile is the configuration file that you used to install the Postgres database. The only requirement on the config file is that the configuration file must be accessible or readable by the "apigee" user.

  12. Update the Postgres database:
    /opt/apigee/apigee-service/bin/apigee-service apigee-postgresql db_upgrade
  13. Run the update utility on your node to update the portal:
    /opt/apigee/apigee-setup/bin/update.sh -c dp -f configFile

    Where configFile is the configuration file that you used to install the portal. The only requirement on the config file is that the configuration file must be accessible or readable by the "apigee" user.

  14. Run Drupal's update.php script by opening the following URL in a browser window:
    http://portal_IP_DNS:8079/update.php
  15. Disable Drupal to maintenance mode:
    1. Select Configuration in the Drupal menu.
    2. On the Configuration page, select Maintenance mode under Development.
    3. Deselect the Put site into maintenance mode box.
    4. Select Save configuration.

Note that the root directory after the update is:

/opt/apigee/apigee-drupal/wwwroot

The upgrade is now complete.
