Upgrading with a hotpatch

You can upgrade GitHub Enterprise Server to the latest patch release using a hotpatch.

You can use hotpatching to upgrade to a newer patch release, but not a feature release. For example, you can upgrade from 2.10.1 to 2.10.5 because they are in the same feature series, but not from 2.10.9 to 2.11.0 because they are in a different feature series.

Hotpatches do not generally require a reboot. If a hotpatch does require a reboot, the GitHub Enterprise Server release notes will indicate the requirement.

Hotpatches require a configuration run, which can cause a brief period of errors or unresponsiveness for some or all services on your GitHub Enterprise Server instance. You are not required to enable maintenance mode during installation of a hotpatch, but doing so will guarantee that users see a maintenance page instead of errors or timeouts. For more information, see "Enabling and scheduling maintenance mode." The hotpatch installation script installs the hotpatch on every node in the cluster and restarts the services in their proper sequence to avoid downtime.

  1. Back up your data with GitHub Enterprise Server Backup Utilities.
  2. From the administrative shell of any node, use the ghe-cluster-hotpatch command to install the latest hotpatch. You can provide a URL for a hotpatch, or manually download the hotpatch and specify a local filename.
    $ ghe-cluster-hotpatch https://HOTPATCH-URL/FILENAME.hpkg

Upgrading with an upgrade package

Use an upgrade package to upgrade a GitHub Enterprise Server cluster to the latest feature release. For example, you can upgrade from 2.11 to 2.13.

Preparing to upgrade

  1. Review Cluster network configuration for the version you are upgrading to, and update your configuration as needed.
  2. Back up your data with GitHub Enterprise Server Backup Utilities.
  3. Schedule a maintenance window for end users of your GitHub Enterprise Server cluster, as it will be unavailable for normal use during the upgrade. Maintenance mode blocks user access and prevents data changes while the cluster upgrade is in progress.
  4. On the GitHub Enterprise Server Download Page, copy the URL for the upgrade .pkg file to the clipboard.
  5. From the administrative shell of any node, use the ghe-cluster-each command combined with curl to download the release package to each node in a single step. Use the URL you copied in the previous step as an argument.
    $ ghe-cluster-each -- "cd /home/admin && curl -L -O  https://PACKAGE-URL.pkg"

  6. Identify the primary MySQL node, which is defined as mysql-master = <hostname> in cluster.conf. This node will be upgraded last.

Upgrading the cluster nodes

  1. Enable maintenance mode according to your scheduled window by connecting to the administrative shell of any cluster node and running ghe-cluster-maintenance -s.
  2. With the exception of the primary MySQL node, connect to the administrative shell of each of the GitHub Enterprise Server nodes. Run the ghe-upgrade command, providing the package file name you downloaded in Step 4 of Preparing to upgrade:
    $ ghe-upgrade PACKAGE-FILENAME.pkg
      > *** verifying upgrade package signature...
      >  497MB 0:00:04 [ 117MB/s] [==========================================>] 100%            
      > gpg: Signature made Fri 19 Feb 2016 02:33:50 PM UTC using RSA key ID 0D65D57A
      > gpg: checking the trustdb
      > gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model
      > gpg: depth: 0  valid:   1  signed:   0  trust: 0-, 0q, 0n, 0m, 0f, 1u
      > gpg: Good signature from "GitHub Enterprise (Upgrade Package Key) > "
  3. The upgrade process will reboot the node once it completes. Verify that you can ping each node after it reboots.
  4. Connect to the administrative shell of the primary MySQL node. Run the ghe-upgrade command, providing the package file name you downloaded in Step 4 of Preparing to upgrade:
    $ ghe-upgrade PACKAGE-FILENAME.pkg
    > *** verifying upgrade package signature...
    >  497MB 0:00:04 [ 117MB/s] [==========================================>] 100%            
    > gpg: Signature made Fri 19 Feb 2016 02:33:50 PM UTC using RSA key ID 0D65D57A
    > gpg: checking the trustdb
    > gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model
    > gpg: depth: 0  valid:   1  signed:   0  trust: 0-, 0q, 0n, 0m, 0f, 1u
    > gpg: Good signature from "GitHub Enterprise (Upgrade Package Key) > "
  5. The upgrade process will reboot the primary MySQL node once it completes. Verify that you can ping each node after it reboots.
  6. Connect to the administrative shell of the primary MySQL node and run the ghe-cluster-config-apply command.
  7. When ghe-cluster-config-apply is complete, check that the services are in a healthy state by running ghe-cluster-status.
  8. Exit maintenance mode from the administrative shell of any node by running ghe-cluster-maintenance -u.
