Running Multiple Servers
There are two ways you can have multiple web servers running on your system:
•
Use virtual servers
•
Install multiple instances of the server
Virtual Servers
Virtual servers allow you, with a single installed server, to offer companies or
individuals domain names, IP addresses, and some server administration
capabilities. For the users, it is almost as if they have their own web server, though
you provide the hardware and basic web server maintenance.
The settings for virtual servers are stored in the
server_root/server_id/
virtual servers, but if you would like to learn more about this file, see the Netscape
Enterprise Server NSAPI Programmer's Guide.
For more information about virtual servers, see Chapter 13, "Using Virtual
Servers."
Installing Multiple Instances of the Server
In past releases of Enterprise Server, virtual servers did not have unique
configuration information. The only way to have servers with separate
configuration information was to create a new server instance. However, with
Enterprise Server 6.0, virtual servers have separate configuration information, so
multiple server instances are no longer required. They are still supported, but
virtual servers are the preferred way to have multiple servers.
If you choose to install multiple server instances, you can use the Administration
Server to:
•
Install multiple copies of the server on Windows NT as separate instances, each
with a different IP address.
•
Configure a set of servers that all use the same IP address, but different port
numbers.
If your system is configured to listen to multiple IP addresses enter one of the IP
addresses that your system is hosting for each server you install.
