Update Apigee Edge 4.18.05 to 4.51.00

This section describes how to perform the following upgrade:

  • From 4.18.05 to 4.51.00

Who can perform the update

The user running the update should be the same as the user who originally installed Edge, or a user running as root.

After you install the Edge RPMs, any user can configure them.

Which components must you update

You must update all Edge components. Edge does not support a setup that contains components from multiple versions.

Automatic propagation of property settings

If you have set any properties by editing .properties files in /opt/apigee/customer/application then these values are retained by the update.

Update prerequisites

Take care of following prerequisites before upgrading Apigee Edge:

  • Backup all nodes
    Before you update, it is recommended to perform a complete backup of all nodes for safety reasons. Use the procedure for your current version of Edge to perform the backup.

    This allows you to have a backup plan, in case the update to a new version doesn't function properly. For more information on backup, see Backup and restore.

  • Ensure Edge is running
    Ensure that Edge is up and running during update process by using the command: 
    /opt/apigee/apigee-service/bin/apigee-all status

New Edge UI

This section lists considerations regarding the new Edge UI.

Install the Edge UI

After you complete the initial installation, Apigee recommends that you install the Edge UI, which is an enhanced user interface for developers and administrators of Apigee Edge for Private Cloud.

For more information, see Install the new Edge UI.

Update the Edge UI

If you installed the Beta version of Edge UI (formerly known as the New Edge experience or UE) in 4.18.05, you must uninstall it and do a fresh install of the 4.19.01, 4.19.06, or 4.50.00 version of the Edge UI. For more information, see The new Edge UI for Private Cloud.

Handling a failed update

In the case of an update failure, you can try to correct the issue, and then run update.sh again. You can run the update multiple times and it continues the update from where it last left off.

If the failure requires that you roll back the update to your previous version, see Roll back 4.50.00 for more.

Logging update information

By default, the update.sh utility writes log information to:

/opt/apigee/var/log/apigee-setup/update.log

If the user running the update.sh utility does not have access to that directory, it writes the log to the /tmp directory as a file named update_username.log.

If the user does not have access to /tmp, the update.sh utility fails.

Zero-downtime update

A zero-downtime update, or rolling update, lets you update your Edge installation without bringing down Edge.

Zero-downtime update is only possible with a 5-node configuration and larger.

The key to zero-downtime upgrading is to remove each Router, one at a time, from the load balancer. You then update the Router and any other components on the same machine as the Router, and then add the Router back to the load balancer.

  1. Update the machines in the correct order for your installation as described Order of machine update.
  2. When it is time to update the Routers, select any one Router and make it unreachable, as described in Enabling/Disabling Server (Message Processor/Router) Reachability.
  3. Update the selected Router and all other Edge components on the same machine as the Router. All Edge configurations show a Router and Message Processor on the same node.
  4. Make the Router reachable again.
  5. Repeat steps 2 through 4 for the remaining Routers.
  6. Continue the update for any remaining machines in your installation.

Take care of the following before/after update:

  • On combined Router and Message Processor node:
    • Before update – perform the following:
      1. Make the Router unreachable.
      2. Make the Message Processor unreachable.
    • After update - perform the following:
      1. Make the Message Processor reachable.
      2. Make the Router reachable.
  • On single Router node:
    • Before update, make the Router unreachable.
    • After update, make the Router reachable.
  • On single Message Processor node:
    • Before update, make the Message Processor unreachable.
    • After update, make the Message Processor reachable.

Using a silent configuration file

You must pass a silent configuration file to the update command. The silent configuration file should be the same one you used to install Edge 4.18.05.

Update to 4.50.00 on a node with an external internet connection

Use the following procedure to update the Edge components on a node:

  1. If present, disable any CRON jobs configured to perform a repair operation on Cassandra until after the update completes.
  2. Log in to your node as root to install the Edge RPMs.
  3. Install yum-utils and yum-plugin-priorities: 
    sudo yum install yum-utils
sudo yum install yum-plugin-priorities
  4. Disable SELinux as described in Install the Edge apigee-setup utility.
  5. If you are installing on Oracle 7.x, run the following command: 
    sudo yum-config-manager --enable ol7_optional_latest
  6. If you are installing on AWS, run the following yum-configure-manager commands: 
    yum update rh-amazon-rhui-client.noarch
sudo yum-config-manager --enable rhui-REGION-rhel-server-extras rhui-REGION-rhel-server-optional
  7. Download the Edge 4.50.00 bootstrap_4.50.00.sh file to /tmp/bootstrap_4.50.00.sh: 
    curl https://software.apigee.com/bootstrap_4.50.00.sh -o /tmp/bootstrap_4.50.00.sh
  8. Install the Edge 4.50.00 apigee-service utility and dependencies: 
    sudo bash /tmp/bootstrap_4.50.00.sh apigeeuser=uName apigeepassword=pWord

    Where uName: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. If you do not, it installs it for you. Use the JAVA_FIX option to specify how to handle Java installation. JAVA_FIX takes the following values:

    • I: Install OpenJDK 1.8 (default).
    • C: Continue without installing Java.
    • Q: Quit. For this option, you must install Java yourself.
  9. Use apigee-service to update the apigee-setup utility: 
    /opt/apigee/apigee-service/bin/apigee-service apigee-setup update
  10. Update the apigee-validate utility on the Management Server, as the following example shows: 
    /opt/apigee/apigee-service/bin/apigee-service apigee-validate update
  11. Update the apigee-provision utility on the Management Server, as the following example shows: 
    /opt/apigee/apigee-service/bin/apigee-service apigee-provision update
  12. Run the update utility on your nodes in the order described in Order of machine update: 
    /opt/apigee/apigee-setup/bin/update.sh -c component -f configFile

    Where component is the Edge component to update. Possible values include:

    • "cs": Cassandra
    • "edge": All Edge components except Edge UI: Management Server, Message Processor, Router, QPID Server, Postgres Server
    • "ldap": OpenLDAP
    • "ps": postgresql
    • "qpid": qpidd
    • "sso": Apigee SSO (if you installed SSO)
    • "ui": Edge UI
    • "zk": Zookeeper

    And configFile is the same configuration file that you used to define your Edge components during the 4.18.05 installation.

    You can run update.sh against all components by setting component to "all", but only if you have an Edge all-in-one (aio) installation profile. For example:

    /opt/apigee/apigee-setup/bin/update.sh -c all -f ./sa_silent_config
  13. Restart the Edge UI component on all nodes running it, if you haven't done so already: 
    /opt/apigee/apigee-service/bin/apigee-service edge-ui restart
  14. Test the update by running the apigee-validate utility on the Management Server, as described in Test the install.

If you later decide to roll back the update, use the procedure described in Roll back 4.50.00.

Update to 4.50.00 from a local repo

If your Edge nodes are behind a firewall, or in some other way are prohibited from accessing the Apigee repository over the Internet, then you can perform the update from a local repository, or mirror, of the Apigee repo.

After you create a local Edge repository, you have two options for updating Edge from the local repo:

  • Create a .tar file of the repo, copy the .tar file to a node, and then update Edge from the .tar file.
  • Install a webserver on the node with the local repo so that other nodes can access it. Apigee provides the NGINX webserver for you to use, or you can use your own webserver.

To update from a local 4.50.00 repo:

  1. Create a local 4.50.00 repo as described in "Create a local Apigee repository" at Install the Edge apigee-setup utility.
  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-4.50.00.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-4.50.00.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_4.50.00.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_4.50.00.sh file to /tmp/bootstrap_4.50.00.sh: 
      /usr/bin/curl http://uName:pWord@remoteRepo:3939/bootstrap_4.50.00.sh -o /tmp/bootstrap_4.50.00.sh

      Where uName:pWord are the username and password you set previously 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-setup utility and dependencies: 
      sudo bash /tmp/bootstrap_4.50.00.sh apigeerepohost=remoteRepo:3939 apigeeuser=uName apigeepassword=pWord apigeeprotocol=http://

      Where uName:pWord are the repo username and password.

  4. Use apigee-service to update the apigee-setup utility, as the following example shows: 
    /opt/apigee/apigee-service/bin/apigee-service apigee-setup update
  5. Update the apigee-validate utility on the Management Server, as the following example shows: 
    /opt/apigee/apigee-service/bin/apigee-service apigee-validate update
  6. Update the apigee-provision utility on the Management Server, as the following example shows: 
    /opt/apigee/apigee-service/bin/apigee-service apigee-provision update
  7. Run the update utility on your nodes in the order described in Order of machine update: 
    /opt/apigee/apigee-setup/bin/update.sh -c component -f configFile

    Where:

    • component is the Edge component to update. You typically update the following components:
      • "cs": Cassandra
      • "edge": All Edge components except Edge UI. The "edge" component includes the Management Server, Message Processor, Router, QPID Server, and Edge Postgres Server.
      • "ldap": OpenLDAP
      • "ps": postgresql
      • "qpid": qpidd
      • "sso": Apigee SSO (if you installed SSO)
      • "ui": Edge UI
      • "zk": Zookeeper
    • configFile is the same configuration file that you used to define your Edge components during the 4.18.05 installation.

    You can run update.sh against all components by setting component to "all", but only if you have an Edge all-in-one (AIO) installation profile. For example:

    /opt/apigee/apigee-setup/bin/update.sh -c all -f /tmp/sa_silent_config
  8. Restart the Edge UI component on all nodes running it, if you haven't done so already: 
    /opt/apigee/apigee-service/bin/apigee-service edge-ui restart
  9. Test the update by running the apigee-validate utility on the Management Server, as described in Test the install.

If you later decide to roll back the update, use the procedure described in Roll back 4.50.00.

Order of machine update

The order that you update the machines in an Edge installation is important:

  • You must update all Cassandra and ZooKeeper nodes before you update any other nodes.
  • For any machine with multiple Edge components (Management Server, Message Processor, Router, QPID Server but not Postgres Server), use the -c edge option to update them all at the same time.
  • If a step specifies that it should be performed on multiple machines, perform it in the specified machine order.
  • There is no separate step to update Monetization. It is updated when you specify the -c edge option.
