Apache 2 HTTPd Server Files

The following list describes the file structure for Apache Web Server:

The string [version] should be expanded to "MAJOR.MINOR". For example, /usr/apache2/2.2/*.

/etc/apache2/[version]/httpd.conf

Contains server configuration files. A newly-installed server contains a default httpd.conf file. This is the main configuration file.

/etc/apache2/[version]/conf.d

Contains additional server configuration files.

By default, server will load all the .conf files placed under this directory. It also has 2 additional .load configuration files-modules-32.load and modules-64.load which contain LoadModule directives for loading the 32 and 64-bit bundled apache modules respectively. All the .conf files in this directory are included by the following line in httpd.conf:

Include /etc/apache2/2.2/conf.d/*.conf. You can add the additional configuration here.

/etc/apache2/[version]/envvars

Contains the environment settings that the server uses at startup.

When the /usr is mounted as read-only, you will not be able to modify the envvars file present in the following path /usr/apache2/[version]/envvars. To modify the environment settings you need to edit the envvars file present in the following path /etc/apache2/[version]/envvars.

/etc/apache2/[version]/magic

Magic data for mod_mime_magic Apache module as documented in the

/usr/apache2/2.2/manual/mod/mod_mime_magic.html file. Editing this file is not recommended.

/etc/apache2/[version]/mime.types

Default MIME types file. This file sets the default list of mappings from filename extensions to content types, changing this file is not recommended. Use the AddType directive instead.

/etc/apache2/[version]/original/

Contents under this directory are delivered as-is from the apache distribution and these files are not meant to be read by the server.

/etc/apache2/[version]/sample-conf.d

Contains sample .conf files. These are not included in the main configuration file. To use the sample file, copy the file to conf.d directory and modify as per the need.

/var/apache2/[version]/libexec/[isainfo]

Any 64-bit modules which are added using apxs(8) are copied into this directory.
