Apache is a powerful web server which serves html/css/cgi/pl out of the box, and can serve other languages/frameworks via extensions.


The [http://httpd.apache.org/ Apache Homepage] says this of Apache:
=== Atualizar a Base de Dados de Pacote ===
'''Sincronize base de dados de pacote local. Isso atualizará sua arvore Portage local com a ultima versão do Funtoo ebuilds.'''
<console>
###i## emerge --sync
</console>


<blockquote>
=== Buscar pacotes ===
The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows NT. The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards.
'''Busca pacotes por nome.'''
</blockquote>
<console>
###i## emerge -s firefox
###i## emerge --search firefox
</console>


== Install ==
'''Busca pacotes pode descrição.'''
=== Configure USE Flags ===
<console>
If you want to enable any of the above use flags, create a file called <tt>/etc/portage/package.use/apache</tt> and add the options that you want to enable to it. For example:
###i## emerge -S web browser
{{file|name=/etc/portage/package.use/apache|desc= |body=
###i## emerge --searchdesc web browser
www-servers/apache ssl threads
</console>
}}


=== Emerge ===
=== Install packages ===
After you have configured the USE flags that you want to build Apache with, emerge it:
'''Instalar pacote.'''
<console>###i## emerge apache</console>
<console>
###i## emerge firefox
</console>


== Configuration ==
'''Instalar múltiplos pacotes.'''
=== System ===
<console>
Many packages have apache2 use flags. These use flags are often required for an application to be supported by Apache. Setting a system wide apache2 use flag is a good idea.
###i## emerge firefox thunderbird
</console>


{{file|name=/etc/portage/make.conf|desc=set system wide apache2 useflag|body=
'''Instalar pacotes. Pedir por confirmação antes de realizar quaisquer alterações. Exibe saída em verbose.'''
USE="...,apache2,..."
<console>
}}
###i## emerge -av firefox
###i## emerge --ask firefox
</console>


=== Package ===
=== Remove packages ===
Apache's configuration files are broken up and located in several spots.
'''Remove package.'''
*<code>/etc/conf.d/apache2</code>
<console>
*<code>/etc/apache2/httpd.conf</code>
###i## emerge -C firefox
*<code>/etc/apache2/modules.d/*</code>
###i## emerge --unmerge firefox
*<code>/etc/apache2/vhosts.d/*</code>
</console>


<code>conf.d</code> controls the init script, adding things to it such as -D SECURITY & -D PHP5 will enable web application fire-walling & the php scripting language.
'''Remove package. Ask for confirmation before performing any changes.'''
<console>
###i## emerge -aC firefox
</console>


<code>httpd.conf</code> controls how the server behaves, at the bottom of the file it has directives to include configuration files ending in .conf in <code>/etc/apache2/modules.d</code> and <code>/etc/apache2/vhosts.d</code>
'''Remove orphaned packages. Ask for confirmation before performing any changes.'''
<console>
###i## emerge -a --depclean
</console>


== Service ==
=== Update packages ===
'''Update all packages.'''
<console>
###i## emerge -uDN @world
</console>


To start apache immediately:
'''Update all packages. Ask for confirmation before performing any changes. Show verbose output.'''
<console>
<console>
###i## rc-service apache2 start
###i## emerge -uavDN @world
</console>
</console>


To start apache upon boot:
'''When upgrading to a new version of perl, it is necessary to also run <code>perl-cleaner</code> afterwards:'''
<console>
<console>
###i## rc-update add apache2
###i## emerge -auvDN @world
###i## perl-cleaner --all
</console>
</console>


== mod_rewrite ==
{{Note|This requirement of running <code>perl-cleaner</code> will eventually go away, once all perl-related ebuilds are updated to EAPI 5. EAPI 5 is a version of the Ebuild specification that supports smart updating of perl-related bits.}}
=== What is <code>mod_rewrite</code>? ===
The [http://httpd.apache.org/docs/current/mod/mod_rewrite.html Apache documentation] describes <code>mod_rewrite</code> as:
 
<blockquote>
The mod_rewrite module uses a rule-based rewriting engine, based on a PCRE regular-expression parser, to rewrite requested URLs on the fly. By default, mod_rewrite maps a URL to a filesystem path. However, it can also be used to redirect one URL to another URL, or to invoke an internal proxy fetch.
</blockquote>
 
=== Setting it up ===
mod_rewrite has a reputation of being difficult to set up.  mod_rewrite requires following symlinks & Order allow,deny (apache 2.2) or Require all granted (apache 2.4) is set.  To test functionality of mod_rewrite we will need to make a few files.
 
{{fancynote|If you want to test this for web applications such as mediawiki adjust the path to <code>/var/www/localhost/htdocs/mediawiki/.htaccess</code>}}
 
{{file|name=/var/www/localhost/htdocs/.htaccess|desc=enable the rewrite engine|body=
RewriteEngine on
RewriteRule ^test.html$ rewrite.html
}}
 
{{file|name=/var/www/localhost/htdocs/test.html|desc=set system wide apache2 useflag|body=
rewrite is not working
}}
 
{{file|name=/var/www/localhost/htdocs/rewrite.html|desc=set system wide apache2 useflag|body=
rewrite is working
}}
 
Then point your browser to http://127.0.0.1/test.html. You should see that the text from rewrite.html has been loaded.

Principiando com o emerge

Emerge é o front-end para o gerenciador de Portage do funtoo. Com o emerge é fácil instalar, atualizar ou remover pacotes.

Atualizar a Base de Dados de Pacote

Sincronize base de dados de pacote local. Isso atualizará sua arvore Portage local com a ultima versão do Funtoo ebuilds. 

root # emerge --sync

Buscar pacotes

Busca pacotes por nome. 

root # emerge -s firefox
root # emerge --search firefox

Busca pacotes pode descrição. 

root # emerge -S web browser
root # emerge --searchdesc web browser

Install packages

Instalar pacote. 

root # emerge firefox

Instalar múltiplos pacotes. 

root # emerge firefox thunderbird

Instalar pacotes. Pedir por confirmação antes de realizar quaisquer alterações. Exibe saída em verbose. 

root # emerge -av firefox
root # emerge --ask firefox

Remove packages

Remove package. 

root # emerge -C firefox
root # emerge --unmerge firefox

Remove package. Ask for confirmation before performing any changes. 

root # emerge -aC firefox

Remove orphaned packages. Ask for confirmation before performing any changes. 

root # emerge -a --depclean

Update packages

Update all packages. 

root # emerge -uDN @world

Update all packages. Ask for confirmation before performing any changes. Show verbose output. 

root # emerge -uavDN @world

When upgrading to a new version of perl, it is necessary to also run perl-cleaner afterwards: 

root # emerge -auvDN @world
root # perl-cleaner --all
   Note

This requirement of running perl-cleaner will eventually go away, once all perl-related ebuilds are updated to EAPI 5. EAPI 5 is a version of the Ebuild specification that supports smart updating of perl-related bits.
