# Configuring and Running the OMT Installer

After the installation packages have been downloaded, validated, and uncompressed in the download folder, you are ready to configure and run the OMT Installer. For a complete list of optional parameters, see OMT Installation CLI Commands.

To configure and run the OMT Installer:

1. Log in to one of the local master nodes where you downloaded and extracted the installation files as the root user. (In this document, the selected master node is referred to as the Initial Master Node. You initiate installations from the Initial Master Node.)
   If you choose to install as a `sudo` user, log in to the master node as the non-root user.
2. Run the OMT Installer on the Initial Master Node with the following commands.

   - For a root user:

       cd {​​unzipped-installer-dir}/installers/cdf
       ./install -m <path_to_a_metadata_file> --cdf-home <path_to_installation_directory> --nfs-server <your_nfs_server_FQDN or IP Address> --nfs-folder <itom_volume_folder>

   - For a sudo user:

       cd {​​unzipped-installer-dir}/installers/cdf
       sudo ./install -m <path_to_a_metadata_file> --cdf-home <path_to_installation_directory> --nfs-server <your_nfs_server_FQDN or IP Address> --nfs-folder <itom_volume_folder>

3. You are prompted for a password, which will be used to log in to the OMT installer portal. For example:

       cd /opt/arcsight/download/installers/cdf/arcsight-platform-installer-x.x.x.x
       ./install -m /opt/arcsight/download/arcsight-platform-installer-xxxxx/metadata/arcsight-suite-metadata-x.x.x.x.tar --cdf-home /opt/arcsight/kubernetes
       --nfs-server yourdomain-nfs.yourenterprise.net --nfs-folder /opt/arcsight-nfs/itom-vol --ha-virtual-ip 216.3.128.12 --tmp-folder /opt/tmp

4. You might need to configure some additional parameters, depending on your organization’s OS, network, and storage configurations.

After the OMT Installer is configured and installed, you can use it to deploy one or more capabilities into the cluster.
