Apache Web Server
Installing Apache under Debian
Installing apache2 is as easy as running apt-get install apache2.
APT will automatically select one of the four engines, usually apache2-mpm-prefork or apache2-mpm-worker (apache2-mpm-event and apache2-mpm-itk aren't recommended). The package's description contains an overview of their differences.
Script / Dynamic content
Apache can use any external program and scripting language, through CGI or FastCgi (libapache2-mod-fcgid).
Apache can also embed some scripts interpreters or connect to an application server to generate dynamic content:
PHP : libapache2-mod-php5
Perl : libapache2-mod-perl2
Ruby : libapache2-mod-ruby
Lisp : libapache2-mod-lisp.
Debian has many modules for Apache, which package names are usually prefixed with libapache2-mod
Once installed, modules can be enabled or disabled with the commands a2enmod and a2dismod.
apt-cache search apache | less
- This will list all the Apache related software available in the Debian repositories. There's "apache" along with all its related packages (-doc, -dev, -common, -perl, ...).
- Apache user (www-data)
- Debian's Apache packages come configured to run as user 'www-data'. This is potentially confusing: files to be served by apache should not be owned by 'www-data', as apache should not normally be allowed to modify them (i.e. as long as you're not running a wiki).
- Apache v1.3
Apache.org is officially encouraging users to switch to apache v2.2. DebianLenny and later releases, don't ship Apache v1.x.
(apache 1.3 release notes: "We strongly recommend that users of all earlier versions, including 1.3 family release, upgrade to to the current 2.2 version as soon as possible.")
