This is the default welcome page used to test the correct
operation of the Apache2 server after installation on Ubuntu systems.
It is based on the equivalent page on Debian, from which the Ubuntu Apache
packaging is derived.
If you can read this page, it means that the Apache HTTP server installed at
this site is working properly. You should replace this file (located at
/var/www/html/index.html) before continuing to operate your HTTP server.
If you are a normal user of this web site and don't know what this page is
about, this probably means that the site is currently unavailable due to
maintenance.
If the problem persists, please contact the site's administrator.
Ubuntu's Apache2 default configuration is different from the
upstream default configuration, and split into several files optimized for
interaction with Ubuntu tools. The configuration system is
fully documented in
/usr/share/doc/apache2/README.Debian.gz. Refer to this for the full
documentation. Documentation for the web server itself can be
found by accessing the manual if the apache2-doc
package was installed on this server.
The configuration layout for an Apache2 web server installation on Ubuntu systems is as follows:
/etc/apache2/
|-- apache2.conf
| `-- ports.conf
|-- mods-enabled
| |-- *.load
| `-- *.conf
|-- conf-enabled
| `-- *.conf
|-- sites-enabled
| `-- *.conf
-
apache2.conf is the main configuration
file. It puts the pieces together by including all remaining configuration
files when starting up the web server.
-
ports.conf is always included from the
main configuration file. It is used to determine the listening ports for
incoming connections, and this file can be customized anytime.
-
Configuration files in the mods-enabled/,
conf-enabled/ and sites-enabled/ directories contain
particular configuration snippets which manage modules, global configuration
fragments, or virtual host configurations, respectively.
-
They are activated by symlinking available
configuration files from their respective
*-available/ counterparts. These should be managed
by using our helpers
a2enmod,
a2dismod,
a2ensite,
a2dissite,
and
a2enconf,
a2disconf
. See their respective man pages for detailed information.
-
The binary is called apache2. Due to the use of
environment variables, in the default configuration, apache2 needs to be
started/stopped with /etc/init.d/apache2 or apache2ctl.
Calling /usr/bin/apache2 directly will not work with the
default configuration.
