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. [[!toc]] ## apache 2 * Make sure the cgi module is loaded. (Ie, `a2enmod cgi`). Note that the cgid module will not work. * Edit /etc/apache2/apache2.conf (or /etc/apache2/mods-available/mime.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`. * If your wiki is in `~/public_html` and does not appear when you enter the URL given by the installer, check that you have the userdir mod enabled (there should be simlinks to userdir.load and userdir.conf in /etc/apache2/modes-enabled). If not, run `a2enmod userdir` and reload apache2. * 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, you need to use a FastCGI wrapper. The wrapper must be started somehow just like any other FastCGI program. You can use launchd on OSX. In Linux, you will need the spawn-fcgi and fcgiwrap packages and start them with: spawn-fcgi -s /tmp/fcgi.socket -n -- /usr/sbin/fcgiwrap This needs to be ran as your user. It can be added to `inittab` or made into a startup script in `init.d`. You may also need to make this file writable by the webserver, if that's running as a different user, e.g.: chmod a+w /tmp/fcgi.socket Then you need an nginx config plugged in that wrapper. Here's an example virtual host configuration: server { #listen 80; ## listen for ipv4; this line is default and implied #listen [::]:80 default_server ipv6only=on; ## listen for ipv6 root /home/anarcat/public_html/wiki.reseaulibre.ca/; index index.html index.htm; # Make site accessible from http://localhost/ server_name wiki.reseaulibre.ca; location / { try_files $uri $uri/ /index.html; } location /ikiwiki.cgi { fastcgi_pass unix:/tmp/fcgi.socket; fastcgi_index ikiwiki.cgi; fastcgi_param SCRIPT_FILENAME /home/anarcat/public_html/ikiwiki.cgi; fastcgi_param DOCUMENT_ROOT /home/anarcat/public_html/wiki.reseaulibre.ca; include /etc/nginx/fastcgi_params; } } Also, note that the `/tmp/fcgi.socket` file needs to be writable by the webserver. I am also unsure as to the security of this setup, as I am using this only on my dev server. Needless to say that [[real fastcgi support|todo/fastcgi_or_modperl_installation_instructions]] would be great. ;) --[[anarcat]] ## boa Edit /etc/boa/boa.conf and make sure the following line is not commented: AddType application/x-httpd-cgi cgi
