It's common to name the [[cgi]] "ikiwiki.cgi", and put it somewhere
|
|
like `~/public_html/ikiwiki.cgi`, or `/var/www/wiki/ikiwiki.cgi`.
|
|
|
|
If you do that, you may find that when trying to edit a page in your wiki,
|
|
you see the raw contents of the ikiwiki.cgi program. Or get a permission
|
|
denied problem.
|
|
|
|
This is because web servers are generally not configured to run cgi scripts
|
|
unless they're in `/usr/lib/cgi-bin/`. While you can put ikiwiki.cgi in
|
|
there if you like, it's better to configure your web server to
|
|
run `.cgi` programs from anywhere.
|
|
|
|
These instructions are for Debian systems, but the basic
|
|
configuration changes should work anywhere.
|
|
|
|
## apache 2
|
|
|
|
* Edit /etc/apache2/apache2.conf and add a line like this:
|
|
|
|
AddHandler cgi-script .cgi
|
|
|
|
* Find the "Options" line for the directory where you've put the
|
|
ikiwiki.cgi, and add "ExecCGI" to the list of options. For example, if
|
|
ikiwiki.cgi is in /var/www/, edit `/etc/apache2/sites-enabled/000-default`
|
|
and add it to the "Options" line in the "Directory /var/www/" stanza.
|
|
Or, if you've put it in a `~/public_html`, edit
|
|
`/etc/apache2/mods-available/userdir.conf`.
|
|
|
|
* You may also want to enable the [[plugins/404]] plugin.
|
|
To make apache use it, the apache config file will need a further
|
|
modification to make it use ikiwiki's CGI as the apache 404 handler.
|
|
Something like this, with the path adjusted to where you've put the CGI:
|
|
|
|
ErrorDocument 404 /cgi-bin/ikiwiki.cgi
|
|
|
|
## lighttpd
|
|
|
|
Here is how to enable cgi on [lighttpd](http://www.lighttpd.net/) and
|
|
configure it in order to execute ikiwiki.cgi wherever it is located.
|
|
|
|
* 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)).
|
|
|
|
* Create `/etc/lighttpd/conf-available/90-ikiwiki-cgi.conf` and add a line like this:
|
|
|
|
cgi.assign = ( "ikiwiki.cgi" => "", )
|
|
|
|
* Activate ikiwiki-cgi by linking `/etc/lighttpd/conf-available/90-ikiwiki-cgi.conf` into `/etc/lighttpd/conf-enabled`.
|
|
|
|
* Restart lighttpd server with something like `/etc/init.d/lighttpd restart`.
|
|
|
|
Note that the first part enables cgi server wide but depending on default
|
|
configuration, it may be not enough. The second part creates a specific
|
|
rule that allow `ikiwiki.cgi` to be executed.
|
|
|
|
**Warning:** I only use this lighttpd configuration on my development
|
|
server (offline). I am not sure of how secure this approach is.
|
|
If you have any thought about it, feel free to let me know.

## nginx
|
|
|
|
* To run CGI under nginx, just use a FastCGI wrapper like [this one](http://technotes.1000lines.net/?p=23). The wrapper must be started somehow just like any other FastCGI program. I use launchd on OSX.

## boa
|
|
|
|
Edit /etc/boa/boa.conf and make sure the following line is not commented:
|
|
|
|
AddType application/x-httpd-cgi cgi
|
