Creating multiple instances of IBM HTTP Server on Windows operating systems

On Windows operating systems, you can create multiple instances of IBM® HTTP Server by manually creating additional service names.

Before you begin

About this task

When you install IBM HTTP Server, you create one IBM HTTP Server as a Windows service with a default name. If you need to run with more than one IBM HTTP Server instance, you can manually create additional service names.

Procedure

Install a new service name.
Use the httpd.exe program, which is located in the bin directory of the IBM HTTP Server installation. The command syntax for installing a new service name is:
```
httpd -k install -n <new_service_name> -f 
   <path_to_new_configuration_file> 
```
This command allows you to associate a unique configuration file with each service name.
Specify different IP addresses or ports in the Listen directives of each configuration file and specify different log file names.
Optional: Change settings of the new service using the Windows Services control panel.
The new service name will have Log On value that is set to Local System Account and will have Startup Type value set to Automatic. You can change these default settings using the Windows Services control panel. It might be necessary to change the Log On setting of the new service name to match the Log On of the main installation in order to ensure that file permissions will allow the new service name to run.
Disable the Fast Response Cache Accelerator (FRCA).
When running multiple instances of IBM HTTP Server, you must disable the FRCA (AFPA directives) in all configuration files.

What to do next

After creating a new service name, you can add it to the WebSphere® Administration Server administrative console by creating a new Web server definition and specifying the new service name and the path to the new configuration file.

The syntax for uninstalling an existing service name is:

httpd -k uninstall -n <service_name>
