# Installing the OMT Infrastructure

This process installs the OMT Installer, with which you can install the browser-based OMT Management Portal for deploying and configuring the ArcSight capabilities.

1. Download arcsight-platform-cloud-installer-23.2.x.zip to a secure network location.
2. SSH to your jump host and become `root`.
3. Upload the arcsight-platform-cloud-installer-23.2.x.zip to a directory on the jump host.
4. Unzip the deployer and run the installation. For example:

    unzip cdf-deployer.zip

    ...

    cd cdf-deployer/

    ./install \
    --k8s-provider AZURE \
    --external-access-host installer.arcsight.private.com \
    --loadbalancer-info  "azure-load-balancer-internal=true;LOADBALANCERIP=10.1.1.101"  \
    --nfs-server 10.1.2.4 \
    --nfs-folder /nfs/itom-vol \
    --registry-url srgdemo.azurecr.io \
    --registry-username srgdemo \
    --registry-password GEev87wtAW+FtBGTyADxgr9Fivg6a2gC \
    --registry-orgname your-org-name
    --noinfra \

The following arguments apply to the `install` command:

`--nfs-server` | Your NFS server private IP or NetApp end IP.
`--registry-url` | Login server (from the Access keys tab in your ACR resource)
`--registry-username` | Username (from the Access keys tab in your ACR resource)
`--registry-password` | Password (from the Access keys tab in your ACR resource)
`--registry-orgname` | Organization name. Use the same value as for the`-o` argument you specified during the uploading of your images to the ACR,
`--external-access-host` | DNS domain name configured earlier. For example, `installer.arcsight.private.com.` If you use a different name for `private-dns` zone in the previous step, then change the value of `--external-access-host` to fit your DNS; that is,`installer.<YOUR NAME>` You can verify this value on the Azure portal, in the main resource group, under Private DNS Zone resource.
`--cloud-provider` | Specifies the cloud provider when installing OMT on a cloud server. The allowed value of this parameter is AZURE.
`--loadbalancer-info` | Specifies load balancer information. The argument`azure-load-balancer-internal=true` is always required. The value of LOADBALANCERIP must be the value specified in Assigning an IP Address to Private DNS.
