Apache 在不同平台和版本上的默认文件布局

https://wiki.apache.org/httpd/DistrosDefaultLayout

This guide lists the default installation layouts for Apache HTTPD on various operating systems and distributions.

While examples in the main Apache HTTP Server documentation assume that you are using the standard file layout distributed from apache.org, many third-party distributors change the layout to conform to local policies. This can make it difficult to follow the examples and to find various important files. Using the information below, you can find where things live on your local install, and compare it to the standard Apache httpd paths.

Debian, Ubuntu (Apache httpd 2.x):

 

ServerRoot              ::      /etc/apache2
DocumentRoot            ::      /var/www
Apache Config Files     ::      /etc/apache2/apache2.conf
                        ::      /etc/apache2/ports.conf
Default VHost Config    ::      /etc/apache2/sites-available/default, /etc/apache2/sites-enabled/000-default
Module Locations        ::      /etc/apache2/mods-available, /etc/apache2/mods-enabled
ErrorLog                ::      /var/log/apache2/error.log
AccessLog               ::      /var/log/apache2/access.log
cgi-bin                 ::      /usr/lib/cgi-bin
binaries (apachectl)    ::      /usr/sbin
start/stop              ::      /etc/init.d/apache2 (start|stop|restart|reload|force-reload|start-htcacheclean|stop-htcacheclean)

 

Notes:

1. The Debian/Ubuntu layout is fully documented in /usr/share/doc/apache2/README.Debian

2. Debian/Ubuntu use symlinks to configure vhosts and load modules. Configuration files are created in their respective sites-available and mods-available directories. To activate vhosts and modules, symlinks are created in the respective sites-enabled and mods-enabled directories to the config files in either sites-available and mods-available. Debian provides scripts to handle this process called 'a2ensite' and 'a2enmod' which activates vhosts and modules.

3. The default vhost is defined in /etc/apache2/sites-available/default, and overrides the DocumentRoot set in the server context.
