Morpheus Agent Install Troubleshooting

When provisioning an Instance, there are network and configuration requirements to consider in order to successfully install the Morpheus Agent. Typically, when a VM Instance is still in the provisioning phase long after the VM is up, the Instance is unable to reach Morpheus. Depending on the Agent install mode, it could also mean Morpheus is unable to reach the Instance.

The most common reason an Agent install fails is the provisioned Instance cannot reach the Morpheus Appliance via the Appliance URL set in Administration > Settings over port 443. When an Instance is provisioned from Morpheus, it must be able to reach the Morpheus appliance via the Appliance URL or the Agent will not be installed.

In addition to the main Appliance URL in Administration > Settings, additional Appliance URLs can be set per Cloud in the Advanced Options section of the Cloud configuration modal when creating or editing a Cloud. When this field is populated, it will override the main Appliance URL for anything provisioned into that Cloud.

Tip

The Morpheus UI current log, located at /var/log/morpheus/morpheus-ui/current, is very helpful when troubleshooting Agent installations.

Agent Install Methods

Morpheus Agent installation supports multiple install methods.

  • SSH/WinRM
  • VM Tools
  • Cloud-Init & Cloudbase-Init
  • Windows Unattended
  • Manual

For All Agent Install Methods

When an Instance is provisioned and the Agent does not install, verify the following for any Agent install mode:

  • The Morpheus Appliance URL (Administration > Settings) is both reachable and resolvable from the provisioned node
  • The Appliance URL begins with https://, not http://

Note

Be sure to use https:// even when using an IP address for the appliance.

  • Inbound connectivity access to the Morpheus appliance from provisioned VMs and container hosts on port 443 (needed for Agent communication)
  • Private (non-Morpheus provided) VM images and templates must have their credentials stored. These can be entered or edited in the Provisioning > Virtual Images section by clicking the Actions dropdown on an imaged detail page and selecting Edit.

Note

Administrator user is required for Windows Agent install.

  • The Instance does not have an IP address assigned. For scenarios without a DHCP server, static IP information must be entered by selecting the Network Type: Static in the Advanced Options section during provisioning. IP Pools can also be created in the Infrastructure > Networks > IP Pools section and added to Cloud network sections for IPAM
  • DNS is not configured and the node cannot resolve the appliance. If DNS cannot be configured, the IP address of the Morpheus appliance can be used as the main or Cloud appliance

SSH

  • Port 22 is open for Linux images, and SSH is enabled
  • Credentials set on the image if using a custom or synced image. Credentials can be entered on images in the Provisioning > Virtual Images section

WinRM

  • Port 5985 must be open and WinRM enabled for Windows images
  • Credentials have been entered on the image if using a custom or synced image. Credentials can be entered on images in the Provisioning > Virtual Images section

Note

Administrator user is required for Windows Agent install.

VMware Tools (vmtools)

  • VMware Tools is installed on the template(s)
  • Credentials have been entered on the image if using custom or synced image. Credentials can be entered on images in the Provisioning > Virtual Images section
  • Sudo priveleges required for Linux
  • Administrator User required for Windows (SID 500)

Cloud-Init

  • Cloud-Init settings configured in Administration > Provisioning section
  • Cloud-Init installed on Virtual Image
  • Cloud-Init enabled on Virtual Image config

Cloudbase-Init

  • Windows Administrator Password defined in Administration > Provisioning section
  • Cloudbase-Init installed on Virtual Image
  • Cloud-Init enabled on Virtual Image config

Note

Unattend Agent Installation and customizations are recommended over Cloudbase-Init

Windows Unattended

  • Windows Administrator Password defined in Administration > Provisioning section
  • VMware: Force Guest Customizations set to forced on Virtual Image config when using DHCP (Static Assignment will already force Guest Customizations)
  • Nutanix & SCVMM: Virtual Image is sysprepped and shutdown, Sysprep Enabled flagged on Virtual Image config

Manual

  • Agent Install scripts can be downloaded from Morpheus and ran manually on the target host when required via Actions -> Download Agent Script on the managed Resource. Please note the script will be unique per managed Resource.

Restarting the Morpheus Agent

In some situations, it may necessary to restart the Morpheus Agent on the host to re-sync communication from the Agent to the Morpheus appliance.

On the target host, run sudo morpheus-node-ctl restart morphd and the Morpheus agent will restart. morpheus-node-ctl status will also show the agent status.

The Morpheus Windows Agent service can be restarted in Administrative Tools -> Services.

Tip

The Morpheus Remote Console is not dependent on Agent communication and can be used to install or restart the Morpheus agent on an Instance.

Uninstall Morpheus Agent

You can use the following to uninstall the linux agent:

sudo rm /etc/apt/sources.list.d/morpheus.list
sudo morpheus-node-ctl kill
sudo apt-get -y purge morpheus-node
sudo apt-get -y purge morpheus-vm-node
sudo systemctl stop morpheus-node-runsvdir
sudo rm -f /etc/systemd/system/morpheus-node-runsvdir.service
sudo systemctl daemon-reload
sudo rm -rf /var/run/morpheus-node
sudo rm -rf /opt/morpheus-node
sudo rm -rf /etc/morpheus/
sudo rm -rf /var/log/morpheus-node
sudo pkill runsv
sudo pkill runsvdir
sudo pkill morphd
sudo usermod -l morpheus-old morpheus-node

CentOS/RHEL 7 Images

For custom CentOS 7 images we highly recommend setting up Cloud-Init and fixing the network device names. More information for custom CentOS images can be found in the CentOS 7 image guide.
