Web Server:

See Below for instructions on splitting the web component over two boxes.  Document contains instructions for both IIS and Apache.

Background

This document describes how to install the web component in 2 pieces: The admin/client console pages behind the firewall and the device access pages in the DMZ.

Before installing the web component, be sure IIS or Apache is installed on both the machine behind the firewall and the one in the DMZ. Also be sure the NotifyLink SQL component is installed.

After NotifyLink is installed, you must install the current NotifyLink patch in both locations. Instructions for doing so are included in this article.

Follow the installation instructions below for the web server you are using. These steps assume NotifyLink is installed in the default location of C:\Program Files\NotifyLink Enterprise Server.

If it is installed in another location, change the path appropriately when following the steps.

SSL

If using SSL, a certificate is needed for the machine in the DMZ.

Apply Current NotifyLink Patch in Both Locations

When applying NotifyLink patches, both servers will need updated. 

1. Before running the patch installer, note the value of the PatchVersion.WebVersion field if it exists.

2. Run the patch installer on one of the servers. 

3. When that is completed, set the PatchVersion.WebVersion to the value noted previously, or set it to zero (0) if the PatchVersion table did not exist.

4. Run the patch installer on the other server.
