    4646To setup Trac environment for `mod_fcgid` it is necessary to use 
    47 `FCGIDDefaultInitEnv` directive. It cannot be used in `Directory` or 
     47`DefaultInitEnv` directive. It cannot be used in `Directory` or 
    4848`Location` context, so if you need to support multiple projects, try 
    4949alternative environment setup below. 
    5050 
    5151{{{ 
    52 FCGIDDefaultInitEnv TRAC_ENV /path/to/env/trac/ 
     52DefaultInitEnv TRAC_ENV /path/to/env/trac/ 
    5353}}} 
    5454 
     
    9494After doing this, we will just have to create a new rule managed by the SCGI handler to access Trac. It can be created in a new virtual server, trac.example.net for instance, and will only need two rules. The '''default''' one will use the SCGI handler associated to the previously created information source. 
    9595The second rule will be there to serve the few static files needed to correctly display the Trac interface. Create it as ''Directory rule'' for ''/chrome/common'' and just set it to the ''Static files'' handler and with a ''Document root'' that points to the appropriate files: ''/usr/share/trac/htdocs/''

     97Note:\\ 
     98If the tracd process fails to start up, and cherokee displays a 503 error page, you might be missing the [http://trac.saddi.com/flup python-flup] package.\\ 
     99Python-flup is a dependency which provides trac with SCGI capability. You can install it on debian based systems with: 
     100{{{ 
     101sudo apt-get install python-flup 
     102}}}

    97104== Simple Lighttpd Configuration == 
     
    122129and you may set one of the two in `trac.fcgi` instead of in `lighttpd.conf` 
    123130using `bin-environment` (as in the section above on Apache configuration). 
     131 
     132Note that lighttpd has a bug related to 'SCRIPT_NAME' and 'PATH_INFO' when the uri of fastcgi.server is '/' instead of '/trac' in this example, see #Trac2418. This should be fixed since lighttpd 1.4.23, and you may need to add `"fix-root-scriptname" => "enable"` as parameter of fastcgi.server.

    125134For using two projects with lighttpd add the following to your `lighttpd.conf`: 
     
    275284Note about running lighttpd with reduced permissions: 
    276285 
    277   If nothing else helps and trac.fcgi doesn't start with lighttpd settings __server.username = "www-data"__, __server.groupname = "www-data"__, then in the `bin-environment` section set `PYTHON_EGG_CACHE` to the home directory of `www-data` or some other directory accessible to this account for writing. 
     286  If nothing else helps and trac.fcgi doesn't start with lighttpd settings `server.username = "www-data"`, `server.groupname = "www-data"`, then in the `bin-environment` section set `PYTHON_EGG_CACHE` to the home directory of `www-data` or some other directory accessible to this account for writing.

    284293!LiteSpeed web server is an event-driven asynchronous Apache replacement designed from the ground-up to be secure, scalable, and operate with minimal resources. !LiteSpeed can operate directly from an Apache config file and is targeted for business-critical environments.
