notes If you did not do a binary install, Apache will in some situation complain about the missing
registry key. This warning can be ignored if the server was otherwise able to find its configuration
file.
The value of this key is the ServerRoot directory which consist the conf subdirectory. When
Apache starts it reads the httpd.conf file from that directory. If this file contains a ServerRoot
directive which contains a different directory from the one obtained from the registry key above,
Apache will forget the registry key and use the directory from the configuration file. If you
copy the Apache directory or configuration files to a new location it is vital that you update the
ServerRoot directive in the httpd.conf file to reflect the new location.

Task Describe the various ways of specifying configuration file on the command
line.

running apache as a service

Apache can be run as a service on Windows NT. There is some highly experimental support for
related behavior on Windows 9x.You can install Apache as a service automatically during the
installation. If you chose to install for all users, the installation will make an Apache service for
you. If you specify to install for yourself only, you can manually register Apache as a service after
the installation. You have to be a member of the Administrators group for the service installation
to succeed.
To be able to manage an Apache service with the monitor, you have to first install the service
(either automatically via the installation or manually).
You can install Apache as a Windows NT service as follows from the command prompt at the
Apache bin subdirectory:

httpd -k install
If you need to specify the name of the service you wish to install, use the following command. You
have to do this if you have several different service installations of Apache on your computer.

httpd -k install -n “MyServiceName”
If you need to have specially named configuration files for different services, you must use this:

httpd -k install -n “MyServiceName” -f “c:\files\my.conf”
If you use the first command without any special parameters except -k install, the service will be
called Apache2 and the configuration will be understood to be conf\httpd.conf.
Removing an Apache service is easy. Just use:

httpd -k uninstall
The specific Apache service to be uninstalled can be specified by using:

httpd -k uninstall -n “MyServiceName”
Normal starting, restarting and shutting down of an Apache service is generally done via the
Apache Service Monitor, by using commands like NET START Apache2 and NET STOP Apache2
or via normal Windows service management. Before starting Apache as a service by any means,
you should test the service’s configuration file by using:
httpd -n “MyServiceName” -t
