| - | ====== Python FastCGI Application and LiteSpeed ====== | ||
| - | This is a generic FCGI how-to for Python applications. Although we use Jon's fcgi python library for this example, you can use any valid Python FCGI module for your own setup. | ||
| - | |||
| - | Live Demo: http://www.litespeedtech.com/products/webserver/demo/ | ||
| - | |||
| - | ===== Requirements ===== | ||
| - | |||
| - | - LiteSpeed | ||
| - | - Python | ||
| - | - Jon's Python FCGI library: [[http://jonpy.sourceforge.net/|jonpy.sourceforge.net]] | ||
| - | |||
| - | |||
| - | ===== Setup ===== | ||
| - | |||
| - | 1) Create a Virtual Host for this setup. From now on we will refer to this vhost as PythonVhost. | ||
| - | |||
| - | 2) Save the following sample Python FCGI application to a path of your choice. We will call this app "demoapp.py" for tutorial purposes. | ||
| - | |||
| - | <code> | ||
| - | #!/usr/bin/python | ||
| - | import jon.cgi as cgi | ||
| - | import jon.fcgi as fcgi | ||
| - | from cgi import escape | ||
| - | import traceback | ||
| - | |||
| - | class Handler(cgi.Handler): | ||
| - | def process(self, req): | ||
| - | req.set_header("Content-Type", "text/html") | ||
| - | req.write("Hello Python! Hello LiteSpeed!<hr size=1>") | ||
| - | keys = req.environ.keys() | ||
| - | keys.sort() | ||
| - | for k in keys: | ||
| - | req.write(escape(k) + " = " + escape(req.environ[k]) + "<br>") | ||
| - | req.write(traceback.print_exc()) | ||
| - | |||
| - | fcgi.Server({fcgi.FCGI_RESPONDER: Handler}).run() | ||
| - | </code> | ||
| - | |||
| - | 3) Go "PythonVhost -> External Apps" tab and create a new "External Application". | ||
| - | |||
| - | <code> | ||
| - | Name: MyPythonFCGI | ||
| - | Address: uds://tmp/lshttpd/mypythonfcgi.sock | ||
| - | Max Connections: 10 | ||
| - | Initial Request Timeout (secs): 10 | ||
| - | Retry Timeout (secs): 0 | ||
| - | Persistent Connection Yes | ||
| - | Connection Keepalive Timeout: 30 | ||
| - | Response Bufferring: No | ||
| - | Auto Start: Yes | ||
| - | Command: /absolutepathto/demoapp.py <--- path to python fcgi app | ||
| - | Back Log: 50 | ||
| - | Instances: 10 | ||
| - | </code> | ||
| - | |||
| - | 4) Go to "PythonVhost -> Contexts" and create a new "FCGI Context". | ||
| - | |||
| - | <code> | ||
| - | URI: /python/ <--- URI path to bind to python fcgi app we created | ||
| - | Fast CGI App: [VHost Level] MyPythonFCGI <--- select the python extapp we just created | ||
| - | </code> | ||
| - | |||
| - | |||
| - | 5) Restart LiteSpeed, "lswsctrl restart", and access your new Pythyon FCGI application with /python/ url to your vhost. Enjoy! =) | ||
