1 It's common to name the [[cgi]] "ikiwiki.cgi", and put it somewhere
2 like `~/public_html/ikiwiki.cgi`, or `/var/www/wiki/ikiwiki.cgi`.
4 If you do that, you may find that when trying to edit a page in your wiki,
5 you see the raw contents of the ikiwiki.cgi program. Or get a permission
8 This is because web servers are generally not configured to run cgi scripts
9 unless they're in `/usr/lib/cgi-bin/`. While you can put ikiwiki.cgi in
10 there if you like, it's better to configure your web server to
11 run `.cgi` programs from anywhere.
13 These instructions are for Debian systems, but the basic
14 configuration changes should work anywhere.
18 * Edit /etc/apache2/apache2.conf and add a line like this:
20 AddHandler cgi-script .cgi
22 * Find the "Options" line for the directory where you've put the
23 ikiwiki.cgi, and add "ExecCGI" to the list of options. For example, if
24 ikiwiki.cgi is in /var/www/, edit `/etc/apache2/sites-enabled/000-default`
25 and add it to the "Options" line in the "Directory /var/www/" stanza.
26 Or, if you've put it in a `~/public_html`, edit
27 `/etc/apache2/mods-available/userdir.conf`.
29 * You may also want to enable the [[plugins/404]] plugin.
30 To make apache use it, the apache config file will need a further
31 modification to make it use ikiwiki's CGI as the apache 404 handler.
32 Something like this, with the path adjusted to where you've put the CGI:
34 ErrorDocument 404 /cgi-bin/ikiwiki.cgi
38 Here is how to enable cgi on [lighttpd](http://www.lighttpd.net/) and
39 configure it in order to execute ikiwiki.cgi wherever it is located.
41 * Activate cgi by linking `/etc/lighttpd/conf-available/10-cgi.conf` into `/etc/lighttpd/conf-enabled` ([doc](http://trac.lighttpd.net/trac/wiki/Docs%3AModCGI)).
43 * Create `/etc/lighttpd/conf-available/90-ikiwiki-cgi.conf` and add a line like this:
45 cgi.assign = ( "ikiwiki.cgi" => "", )
47 * Activate ikiwiki-cgi by linking `/etc/lighttpd/conf-available/90-ikiwiki-cgi.conf` into `/etc/lighttpd/conf-enabled`.
49 * Restart lighttpd server with something like `/etc/init.d/lighttpd restart`.
51 Note that the first part enables cgi server wide but depending on default
52 configuration, it may be not enough. The second part creates a specific
53 rule that allow `ikiwiki.cgi` to be executed.
55 **Warning:** I only use this lighttpd configuration on my development
56 server (offline). I am not sure of how secure this approach is.
