3-Node HA CentOS / RHEL Upgrade

The following covers upgrading the Morpheus App nodes in 3 Node HA configurations to v6.0.4.

Warning

As a best practice, always backup your database prior to any upgrade.

Important

The following is only for “3 Node HA” Architecture configurations.

v6.0.4 Upgrade

Warning

Rolling upgrades to v6.0.4 are not supported

Important

It is important to stop the morpheus-ui service on all app nodes prior to upgrade. Failure to do so will resilt in a flood of log errors due to previous message serializaiton conflict. The messages will eventually expire and the logs will clear.

Warning

Morpheus v6.0.4 contains new node and VM node packages that require 3.5GB of storage. It is safe to run sudo rm -Rf /var/opt/morpheus/package-repos/* after v6.0.4 package installation and before reconfigure to clean old node and vm node packages from the package-repo when room is needed.

  1. Starting with Node 3, on All App Nodes, stop the morpheus-ui services via morpheus-ctl stop morpheus-ui. If you receive a timeout, run morpheus-ctl graceful-kill morpheus-ui.

    [root@app-server-3 ~]# morpheus-ctl stop morpheus-ui

    [root@app-server-2 ~]# morpheus-ctl stop morpheus-ui

    [root@app-server-1 ~]# morpheus-ctl stop morpheus-ui

  2. Upgrade the RPM package on Node 1, then run a Reconfigure on Node 1

    [root@app-server-1 ~]# sudo wget https://packageUrl.morpheus-appliance-x.x.x-x.x86_64.rpm
[root@app-server-1 ~]# sudo rpm -Uhv morpheus-appliance-x.x.x-x.x86_64.rpm
[root@app-server-1 ~]# sudo morpheus-ctl reconfigure

    Note

    All services will automatically be stopped and started during the reconfigure process. After the reconfigure has succeeded, tail the ui service to watch ui startup logs with morpheus-ctl tail morpheus-ui.

  3. Once Node 1 upgrade has completed and the ui is available, upgrade the RPM package on Node 2, then run a Reconfigure on Node 2.

    [root@app-server-2 ~]# sudo wget https://packageUrl.morpheus-appliance-x.x.x-x.x86_64.rpm
[root@app-server-2 ~]# sudo rpm -Uhv morpheus-appliance-x.x.x-x.x86_64.rpm
[root@app-server-2 ~]# sudo morpheus-ctl reconfigure

  4. Then upgrade the RPM package on Node 3, then run a Reconfigure on Node 3

    [root@app-server-3 ~]# sudo wget https://packageUrl.morpheus-appliance-x.x.x-x.x86_64.rpm
[root@app-server-3 ~]# sudo rpm -Uhv morpheus-appliance-x.x.x-x.x86_64.rpm
[root@app-server-3 ~]# sudo morpheus-ctl reconfigure

  5. The upgrade is complete and the Morpheus-ui services should be running with clustered Elasticsearch and RabbitMQ services across the 3 nodes.

Important

If reconfigure after a rpm package upgrade stalls or hangs on starting a service (mysql, rabbitmq, elasticsearch …) it is possible the morpheus-runsvdir service did not start or a process it was managing was manually shutdown or killed. To resolve, run systemctl stop morpheus-runsvdir then systemctl start morpheus-runsvdir, then run reconfigure again, morpheus-ctl reconfigure.
