Installation steps

To deploy the OpsRamp Gateway using the ISO:

1. Connect to the ESXi server.

2. Select Create New Virtual Machine.

3. Enter the following information for the virtual machine:

   • Configuration: Select Typical.

   • Guest OS family: Select Linux.
   • Guest OS version: Select Ubuntu Linux (64-bit).
   • Storage: Select a destination storage section to store the virtual machine files.
   • Network: Select the number of NICs to connect to the network and select Connect at Power ON.
   • Create a Disk:
     • Enter the disk size and units. The recommended size is 40 GB.
     • Select the datastore type from the list.
   • Ready to Complete: View and verify the configuration summary of the new virtual machine.
     
     

4. Select Edit the virtual machine settings before completion and click Continue.

5. In the New Virtual Machine Properties window, click the Hardware tab and do the following:

   • In the Memory Configuration section, enter the memory size and the corresponding unit. The recommended size is 8 GB.

   • CPUs: Enter the number of CPUs. The recommended cores are 4.

   • New CD/DVD: Select Data Store ISO and browse to the location where you downloaded the gateway ISO file.

   • Verify the remaining hardware details and click Finish.

     The ESXi server displays the new virtual machine. To power on the machine, right-click the machine > Power > Power On.

   • Click Enter to start the installation of the gateway.

   • Log in to the gateway using the default credentials provided in the Activation tab inside the Gateway Collector Profiles section.

Note:

• We recommend you to set a unique hostname once the gateway is provisioned. This best practice ensures that you have a unique host name on the network.

  Update the hostname
  Use the following command to update the hostname:

      sudo opsramp-collector-start setup updatehostname <new hostname>
      

  Run the following command to change the default OpsRamp Gateway password:

      sudo passwd gateway-admin
      

Install Kubernetes

To run the OpsRamp Gateway, you need to install the Kubernetes on the host.

Run the below command:

sudo opsramp-collector-start setup init
