h1. Configuration
How much time do you have to set up lighttpd? 5 minutes? 10 minutes? More?
h2. 5 minutes
Want to run a fast, low-resource server for static content? It's easy:
<pre>
server.document-root = "/var/www/servers/www.example.org/pages/"
server.port = 3000
mimetype.assign = (
".html" => "text/html",
".txt" => "text/plain",
".jpg" => "image/jpeg",
".png" => "image/png"
)
</pre>
lighttpd will listen on TCP port 3000 and bind to all interfaces by default. The few important MIME types are assigned
and the document root (the base directory that is used for all requests) is set. The files in the document root have to be
readable by the user starting the web server.
First, check that your config is ok:
<pre>
$ lighttpd -t -f lighttpd.conf
</pre>
Now start the server for testing:
<pre>
$ lighttpd -D -f lighttpd.conf
</pre>
and point your browser to http://127.0.0.1:3000/
To stop the server again, just press ctrl-c.
h3. A real daemon
Next you should familiarize yourself with some settings necessary for your server's security:
<pre>
server.document-root = "/var/www/servers/www.example.org/pages/"
server.port = 80
server.username = "www"
server.groupname = "www"
mimetype.assign = (
".html" => "text/html",
".txt" => "text/plain",
".jpg" => "image/jpeg",
".png" => "image/png"
)
static-file.exclude-extensions = ( ".fcgi", ".php", ".rb", "~", ".inc" )
index-file.names = ( "index.html" )
</pre>
Now the web server is listening on port 80, the default for HTTP traffic, and will switch to the user <code>www</code> and the group <code>www</code>.
The server has to be started as root to take control of port 80, but it's not necessary or a good idea to continue running as root after port acquisition.
Lastly, we forbid access to the source of some types of files which will be used later for generating dynamic content, and we rewrite
all requests to a directory to the <code>index.html</code> file in that directory.
Assuming you have already created the <code>/etc/init.d/lighttpd</code> service as described in [[TutorialInstallation]], place the config file in <code>/etc/lighttpd/lighttpd.conf</code> and start the server with:
<pre>
# /etc/init.d/lighttpd start
</pre>
To stop it use:
<pre>
# /etc/init.d/lighttpd stop
</pre>
h2. 10 minutes
Conditionals, conditionals, conditionals:
The most important part in Lighty's configuration is the use of conditionals. Using simple comparisons or regular expressions, they control
if a default setting will be overridden or not.
<pre>
server.document-root = "/var/www/servers/www.example.org/pages/"
server.port = 80
server.username = "www"
server.groupname = "www"
mimetype.assign = (
".html" => "text/html",
".txt" => "text/plain",
".jpg" => "image/jpeg",
".png" => "image/png"
)
static-file.exclude-extensions = ( ".fcgi", ".php", ".rb", "~", ".inc" )
index-file.names = ( "index.html" )
$HTTP["host"] == "www2.example.org" {
server.document-root = "/var/www/servers/www2.example.org/pages/"
}
</pre>
Now we have a new virtual server which will use the same settings as the first server, only the document root will be replaced by a new one.
This server will also have a download area which will use the built-in directory listing feature:
<pre>
server.document-root = "/var/www/servers/www.example.org/pages/"
server.port = 80
server.username = "www"
server.groupname = "www"
mimetype.assign = (
".html" => "text/html",
".txt" => "text/plain",
".jpg" => "image/jpeg",
".png" => "image/png"
)
static-file.exclude-extensions = ( ".fcgi", ".php", ".rb", "~", ".inc" )
index-file.names = ( "index.html" )
$HTTP["host"] == "www2.example.org" {
server.document-root = "/var/www/servers/www2.example.org/pages/"
$HTTP["url"] =~ "^/download/" {
dir-listing.activate = "enable"
}
}
</pre>
As you can see, conditionals can be nested: only the <code>download</code> folder and its subfolders have the directory listings
enabled.
There's also <code>else</code> clause for conditionals. Despite the name, it's more similar to <code>else if</code> construct from some programming languages, as it has to be followed by another condition.
Here's an example of conditionals-based vhosts. <code>else</code> is being used to configure behavior that should be present only in "default" vhost.
<pre>
$HTTP["host"] == "example.org" {
# options specific to example.org
expire.url = ( "" => "access plus 25 hours" )
} else $HTTP["host"] == "static.example.org" {
# options specific to static.example.org
expire.url = ( "" => "access plus 2 weeks" )
} else $HTTP["host"] =~ "" {
# options applied to any other vhosts present on this ip
# ie. default options
expire.url = ( "" => "access plus 3 hours" )
}
</pre>
Now that we've covered the basics, you're ready to learn some more advanced topics like "includes":http://blog.lighttpd.net/articles/2005/11/25/simplify-your-configfiles-with-includes and configuring PHP with [[lighttpd:Docs_ModFastCGI|FastCGI]]
h2. After 30 minutes
Now you know the basic setup, include files, and maybe even how to set up PHP or Ruby. But there's so much more to find out.
Most of it is described in examples in the default configuration file that you can find in the <code>doc</code> directory of the tarball or in the repository (source:trunk/doc/lighttpd.conf).
