-====== Web Server Configuration ======
-===== Packages =====
-To install Apache and PHP on Ubuntu:
-<code bash>
-sudo apt-get install apache2
-sudo apt-get install php5 libapache2-mod-php5
-</code>
-===== Apache =====
-To start/stop/restart the service:
-<code bash>
-sudo /etc/init.d/apache2 start
-sudo /etc/init.d/apache2 stop
-sudo /etc/init.d/apache2 restart
-</code>
-===== Security =====
-==== Directory Listing ====
-The default settings allow listing of the directory content. To prevent this, modify ''/etc/apache2/sites-available/default'' from:
-<file>
-	<Directory /var/www/>
-		Options Indexes FollowSymLinks MultiViews
-		AllowOverride None
-		Order allow,deny
-		allow from all
-	</Directory>
-</file>
-to:
-<file>
-	<Directory /var/www/>
-		Options -Indexes FollowSymLinks MultiViews
-		AllowOverride None
-		Order allow,deny
-		allow from all
-	</Directory>
-</file>
-**i.e., add '-' to 'Indexes'**
-===== PHP =====
-==== Info ====
-To find out the ''uid'' and ''gid'', execute the following script:
-<code php>
-<?php
-if(function_exists('posix_geteuid')){
-    // use posix to get current uid and gid
-    $uid   = posix_geteuid();
-    $usr   = posix_getpwuid($uid);
-    $user  = $usr['name'];
-    $gid   = posix_getegid();
-    $grp   = posix_getgrgid($gid);
-    $group = $grp['name'];
-}else{
-    // try to create a file and read it's ids
-    $tmp = tempnam ('/tmp', 'check');
-    $uid = fileowner($tmp);
-    $gid = filegroup($tmp);
-    // try to run ls on it
-    $out = `ls -l $tmp`;
-    $lst = explode(' ',$out);
-    $user  = $lst[2];
-    $group = $lst[3];
-    unlink($tmp);
-}
-echo "Your PHP process seems to run with the UID $uid ($user) and the GID $gid ($group)\n"; ?>
-</code>
-Under a standard installation, both the ''uid'' and the ''gid'' are ''www-data''
-==== Problems and Solutions====
-If the browser asks to download the php files (instead of parsing them), comment all lines from <IfModule mod_userdir.c> to the next </IfModule> in ''/etc/apache2/mods-available/php5.conf'' and restart apache2.
-===== Dokuwiki Installation =====
-==== Permissions ====
-Make the permissions more restrictive for security reasons. Assuming the wiki is installed in ''/var/www/wiki''
-<code bash>
-# change the ownership
-sudo chown -R root:www-data /var/www/wiki
-# make data, conf, and lib writable by group
-sudo chmod -R g+w /var/www/wiki/data /var/www/wiki/conf /var/www/wiki/lib
-# restrict access by other
-sudo chmod -R o-rwx /var/www/wiki
