Apache web server install on Gentoo

Emerge steps

use flags : add at least apache2 and php in your make.conf

install

    emerge -av apache
    emerge -av php

Configuration

Edit the file named /etc/apache2/httpd.conf and add a ServerName. The value localhost will do if you just want to do some test on your machine.
```
    ServerName localhost
```
include PHP module in your Apache configuration, by editing /etc/conf.d/apache2
```
    APACHE2_OPTS="-D PHP5 ..."
```
Start the service on your machine
```
    /etc/init.d/apache2 start
```

Note that apache will fail silently in case you haven't set an alias between localhost and the name of your machine. To see this, check if httpd is running. If not, see the log file in /var/log/:

  gesundheit apache2 # cat /var/log/apache2/error_log 
  [Sun Jun 07 14:04:24 2009] [alert] (EAI 2)Name or service not known: mod_unique_id: unable to find IPv4 address of "gesundheit"
  Configuration Failed

This can be fixed (ref) setting the alias in /etc/hosts

  gesundheit apache2 # cat /etc/hosts 
  ...
  # IPv4 and IPv6 localhost aliases
  127.0.0.1     localhost       gesundheit
  ::1           localhost       gesundheit
  ...

Now you can check everything's working fine by visiting http://localhost in your browser.
as a quick start you can already make some HTML pages available on your web server, by adding a Directory section to your /etc/apache2/httpd.conf file:
```
<Directory /var/www/localhost/htdocs>
Options Indexes Includes FollowSymLinks
order allow,deny
allow from all
</Directory>
```
