This challenge has been raised before, and there's no easy answer that I know of.
What you can do is use a DEFINE statement to set the server root directory in a configuration variable, and then reference that throughout the file in directives that need a path. That way you only need to define the path in one place near the top of the configuration, e.g.
| Code: | Define SRVROOT D:/Tools/Apache24
ServerRoot "${SRVROOT}"
DocumentRoot "${SRVROOT}/htdocs"
etc |
Additionally, if you want the server root to be defined outside the configuration file, you can pass an OS environment variable to Apache startup (say APACHE_ROOT) using a -D option, which can then be used to define the SRVROOT e.g.
| Code: | # Define SRVROOT if APACHE_ROOT defined.
#
<IfDefine APACHE_ROOT>
Define SRVROOT ${APACHE_ROOT}
</IfDefine>
# Define SRVROOT if APACHE_ROOT not defined.
#
<IfDefine !APACHE_ROOT>
Define SRVROOT "D:/Tools/Apache24"
</IfDefine>
ServerRoot "${SRVROOT}"
DocumentRoot "${SRVROOT}/htdocs" |
See post https://www.apachelounge.com/viewtopic.php?t=8611 for more details, including how this technique can be used to pass a location path variable to an Apache Windows service. |

Hi,
In httpd.conf, I use :
| Code: | Define VERSION_APACHE 2.4.52
Define INSTALL_DIR E:/wamp64
Define APACHE_DIR ${INSTALL_DIR}/bin/apache/apache${VERSION_APACHE}
Define SRVROOT ${INSTALL_DIR}/bin/apache/apache${VERSION_APACHE}
...
<IfModule fcgid_module>
Define PHPROOT ${INSTALL_DIR}/bin/php/php
...
</IfModule> |
The variables VERSION_APACHE and INSTALL_DIR are automatically filled in when installing an Apache version.
And, for the fcgid mode, in the VirtualHost definitions, I use :
| Code: | <IfModule fcgid_module>
Define FCGIPHPVERSION "7.0.33"
FcgidInitialEnv PHPRC ${PHPROOT}${FCGIPHPVERSION}
<Files ~ "\.php$">
Options +Indexes +Includes +FollowSymLinks +MultiViews +ExecCGI
AddHandler fcgid-script .php
FcgidWrapper "${PHPROOT}${FCGIPHPVERSION}/php-cgi.exe" .php
</Files>
</IfModule>
