# Install CGI::Fast, on Debian/Ubuntu it's in libcgi-fast-perl.
# You don't have to set/change cgiurl_graph, just use the same value in the lighttpd config (the munin fastcgi script doesn't care). The default value is "/cgi-bin/munin-cgi-graph".
# Set "graph_strategy cgi" in munin.conf
# spawn the munin-fastcgi-graph FastCGI application (See [[spawn-fcgi:Basic_Ideas|recommended way to supervise it]]):
<pre>
/usr/bin/spawn-fcgi -n -s /var/run/lighttpd2/munin-fastcgi-graph.sock -u munin -U www-data -- /usr/lib/cgi-bin/munin-fastcgi-graph
</pre>
# setup your munin vhost for lighttpd2
<pre>
if req.path =^ "/cgi-bin/" {
core.wsgi ( "/cgi-bin/munin-cgi-graph", { ${ fastcgi "unix:/var/run/lighttpd2/munin-fastcgi-graph.sock"; } );
} else {
docroot "/var/cache/munin/www"; # or whatever your htmldir is
index ( "index.html" );
expire "modification 5 minutes";
}
</pre>
You need some basics for this if you don't already have them:
<pre>
setup {
module_load ( "mod_expire", "mod_fastcgi", "mod_lua" );
lua.plugin "core.lua";
}
</pre>
# example munin.conf snippet
<pre>
htmldir /var/cache/munin/www
graph_strategy cgi
cgiurl_graph /cgi-bin/munin-cgi-graph
</pre>
