To install Flup (http://www.saddi.com/software/flup/) First,
This is a library of Python processing FastCGI.

FACTCGI uses the C/S model to run a process independently. Web server (Apache, httpd,..) when a request needs to be processed Communicate directly with the factcgi process.

The Web server can be connected to FastCGI server in two ways:
1. Unix domain sockets (or Win32 "Named pipes")
2. TCP socket
Typically, TCP sockets are simpler because permissions issues are better configured.

How to start the FACTCGI server:
To the project directory, execute:
./manage.py runfcgi [Options]
If you want to see Help:
./manage.py runfcgi Help

In the options, you need to specify a socket or combination of host and port, so that when you start Web server, you can connect to the FACTCGI server by using this information.

Example

In a TCP port, run a server in a thread:
./manage.py runfcgi method=threaded host=127.0.0.1 port=3033

Run a preforked server on the Unix domain socket:
./manage.py runfcgi method=prefork Socket=/home/user/mysite.sock pidfile=django.pid

Do not execute as a background process (for debugging purposes):
./manage.py runfcgi Daemonize=false Socket=/tmp/mysite.sock

How to stop the FastCGI process in the background:
1. If the Pidfile attribute is specified, you can do this: Kill ' cat $PIDFILE '. Where $PIDFILE is the pidfile option you specified.

To restart the background factcgi process on Unix, execute the following shell script:

#!/bin/bash

# Replace these three settings.
Projdir= "/home/user/myproject"
pidfile= "$PROJDIR/mysite.pid"
socket= "$PROJDIR/mysite.sock"

CD $PROJDIR
If [-f $PIDFILE]; Then
Kill ' cat--$PIDFILE '
Rm-f--$PIDFILE
Fi

Exec/usr/bin/env-\
Pythonpath= ". /python: "\
./manage.py runfcgi socket= $SOCKET pidfile= $PIDFILE


Apache settings:
1. Need to install the mod_fastcgi
2. Edit httpd.conf:
(1) Use fastcgiexternalserver to point to the location of the FastCGI server
The socket can also be specified with the host + port. Example:

# Connect to FastCGI via a socket/named pipe.
Fastcgiexternalserver/home/user/public_html/mysite.fcgi-socket/home/user/mysite.sock

# Connect to FastCGI via a TCP host/port.
Fastcgiexternalserver/home/user/public_html/mysite.fcgi-host 127.0.0.1:3033

Regardless of the above situation,/home/user/public_html/mysite.fcgi This file does not need to exist. Its role indicates that the WEB server as a URL indicates which requests need to be FastCGI to be processed.

(2) Use Mod_rewrite to assign URLs that need to be processed to FastCGI.

Example:
<virtualhost 12.34.56.78>
ServerName example.com
Documentroot/home/user/public_html
Alias/media/home/user/python/django/contrib/admin/media
Rewriteengine on
Rewriterule ^/(media.*) $/$1 [qsa,l]
Rewritecond%{request_filename}!-f
Rewriterule ^/(. *) $/mysite.fcgi/$1 [qsa,l]
</VirtualHost>

The rewritten URL indicated here is the one in the fastcgiexternalserver above.
The above configuration will not start with/media/, or a request to a nonexistent file, to FastCGI.

LIGHTTPD Configuration

LIGHTTPD Natural support for FastCGI.
First make sure that your mod_fastcgi is in the module list, and after Mod_rewrite and Mod_access, before Mod_accesslog.
In order to serve admin media, you may also need to mod_alias.
In the LIGHTTPD configuration file, add the following paragraph:

Server.document-root = "/home/user/public_html"
Fastcgi.server = (
    "/mysite.fcgi" = (
        "Main" = (
             # Use Host/port instead of socket for TCP fastcgi
         ;    # "Host" = "127.0.0.1",
             # "Port" = 3033,
            "socket" = "/ Home/user/mysite.sock ",
           " check-local "= > "Disable",
       )
   ),
)
Alias.url = (
    "/media/" = "/home/user/django/contrib/admin/media/",
)

Url.rewrite-once = (
"^ (/media.*) $" = "$",
"^/favicon\.ico$" = "/media/favicon.ico",
"^ (/.*) $" = "/mysite.fcgi$1",
)

You can also run multiple Django on a lighttp server. Just specify a separate FastCGI host for each application.

How to run Django/apache on a shared web hosting:

Edit. Htaccess:
AddHandler Fastcgi-script. fcgi
Rewriteengine on
Rewritecond%{request_filename}!-f
Rewriterule ^ (. *) $ mysite.fcgi/$1 [qsa,l]

Then write a mysite.fcgi executable script:

#!/usr/bin/python
Import sys, OS

# ADD a custom Python path.
Sys.path.insert (0, "/home/user/python")

# Switch to the directory of your project. (Optional.)
# Os.chdir ("/home/user/myproject")

# Set the django_settings_module environment variable.
os.environ[' django_settings_module '] = "myproject.settings"

From django.core.servers.fastcgi import runfastcgi
runfastcgi (method= "threaded", daemonize= "false")

After updating the code, you can instruct Apache to restart the Django program by re-uploading the mysite.fcgi file.
If you have Shell permissions, you can change the timestamp directly with the Touch command:
Touch mysite.fcgi
