3 Using Fcgiwrap

Fcgiwrap is a CGI wrapper that can be used for shared hosting environments because it allows each vhost to use its own cgi-bin directory.

As there's no fcgiwrap package for OpenSUSE, we must build it ourselves. First we install some prerequisites:

zypper remove patterns-openSUSE-minimal_base

zypper install git patch automake glibc-devel gcc flex compat-readline4 db-devel wget gcc-c++ make vim libtool FastCGI-devel

Create the following symlinks:

ln -s /usr/include/fastcgi/fastcgi.h /usr/local/include/
ln -s /usr/include/fastcgi/fcgi_config.h /usr/local/include/
ln -s /usr/include/fastcgi/fcgi_stdio.h /usr/local/include/
ln -s /usr/include/fastcgi/fcgiapp.h /usr/local/include/
ln -s /usr/include/fastcgi/fcgimisc.h /usr/local/include/
ln -s /usr/include/fastcgi/fcgio.h /usr/local/include/
ln -s /usr/include/fastcgi/fcgios.h /usr/local/include/

Now we can build fcgiwrap as follows:

cd /usr/local/src/
git clone git://
cd fcgiwrap
autoreconf -i
make install

This installs fcgiwrap to /usr/local/sbin/fcgiwrap.

Next we install the spawn-fcgi package which allows us to run fcgiwrap as a daemon:

zypper install spawn-fcgi

We can now start fcgiwrap as follows:

spawn-fcgi -u nginx -g nginx -s /var/run/fcgiwrap.socket -S -M 0700 -F 1 -P /var/run/ -- /usr/local/sbin/fcgiwrap

You should now find the fcgiwrap socket in/var/run/fcgiwrap.socket, owned by the user and group nginx.

If you don't want to start fcgiwrap manually each time you boot your system, open /etc/init.d/boot.local...

vi /etc/init.d/boot.local

... and add the spawn-fcgi command at the end of the file - this will automatically start fcgiwrap at the end of the boot process:

/usr/bin/spawn-fcgi -u nginx -g nginx -s /var/run/fcgiwrap.socket -S -M 0700 -F 1 -P /var/run/ -- /usr/local/sbin/fcgiwrap

Now open your vhost configuration file...

vi /etc/nginx/nginx.conf

... and add a location /cgi-bin {} section to the server {} container:

server {
   location /cgi-bin/ {
     # Disable gzip (it makes scripts feel slower since they have to complete
     # before getting gzipped)
     gzip off;
     # Set the root to /usr/lib (inside this location this means that we are
     # giving access to the files under /usr/lib/cgi-bin)
     root  /srv/www/;
     # Fastcgi socket
     fastcgi_pass  unix:/var/run/fcgiwrap.socket;
     # Fastcgi parameters, include the standard ones
     include /etc/nginx/fastcgi_params;
     # Adjust non standard parameters (SCRIPT_FILENAME)
     fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;

Reload nginx:

/etc/init.d/nginx reload

Next we create our cgi-bin directory - /srv/www/ because we defined root /srv/www/; in the location /cgi-bin {} container:

mkdir /srv/www/

Now we place our CGI scripts in it and make them executable. For testing purposes I will create a small Hello World Perl script (instead of hello_world.cgi you can also use the extension .pl ->

vi /srv/www/

#!/usr/bin/perl -w
     # Tell perl to send a html header.
     # So your browser gets the output
     # rather then <stdout>(command line
     # on the server.)
print "Content-type: text/html\n\n";
     # print your basic html tags.
     # and the content of them.
print "<html><head><title>Hello World!! </title></head>\n";
print "<body><h1>Hello world</h1></body></html>\n";

chmod 755 /srv/www/

Open a browser and test the script:

If all goes well, you should get the following output:
