Most of these options are not required for most sites. Typically, all you need is to specify the --prefixoption and any options to enable or disable one or more modules. For example, say you do not want to install the CGI module on your system. You can run the configurescript using the --disable-cgi --disable-cgidoptions to disable CGI support. Similarly, to disable the Server-Side Include (SSI) support you can use the --disable-includeoption.
After you have configured Apache using the configurescript, you can use the config.statusscript instead of configurefor any subsequent configuration needs. By using the config.statusscript, you can reuse your previous configura-tion and add or subtract new opconfigura-tions. For example, say you configured Apache with the following command line:
./configure --prefix=/usr/local/apache --disable-cgi --disable-cgid
and a few days later decided to disable SSI. You can now use:
./config.status --disable-include
When you recompile Apache, the CGI modules will still not be included, because ./config.statusstores the options that you specified using the configurescript earlier.
If you wish to start fresh, use configureevery time.
