A maintenance / info for page for Padre trac

if you create a dir call trac off web root

├── trac
│ ├── index.html
│ ├── logo.png
│ └── trac_logo_mini.png

add enc files

then you can use the a2... command

sudo a2dissite trac.conf && sudo service apache2 reload

sudo a2ensite trac.conf && sudo service apache2 reload

and now we have info page when trac is down.

It is simple and quite clean, but any body want to make it better or
cleaner, be my guest.

I am not sure how the a2dissite would help. The trac is in a
<Location /trac/>
within our VirtualHost

I think you can add some static pages to what
padre/template.padre.perlide.org in SVN
generates as that is what drives the static site. I just tried it. As long as I
have trac enabled you see trac but if I comment it out you see the static pages.

Though hopefully we won't see serious downtime for a while.

Good

now we can start on the next step

let us assume that in /etc/apache2/sites-available/

that there is a file called padre_trac

we need to rename it to trac_mod_python.conf

using a2dissite padre_trac
reload apache

that static pages will kick in

now we can rename it to trac_mod_python.conf

then using
a2ensite trac_mod_python.conf

we will be back on line


Now for the mod_wsgi

we create a file in /etc/apache2/sites-available/

trac_wsgi.conf

install mod_wsgi (apt)

and


trac
├── apache
│   └── trac.wsgi
├── conf
├── db
...

enc trac_wsgi.conf, trac.wsgi

tweak above for local settings

then you can just use a2...

to to unload mod_python and load wsgi configuration

have fun

ps only one more step after this to go :)

sys.stdout = sys.stderr 
import os 

os.environ['PYTHON_EGG_CACHE'] = '/usr/src/trac/eggs'
os.environ['TRAC_ENV_INDEX_TEMPLATE'] = '/usr/src/trac/templates'

import trac.web.main

def application(environ, start_response):
    environ['trac.locale'] = 'en_GB.UTF-8'
    environ['trac.env_path'] = '/usr/src/trac'
    return trac.web.main.dispatch_request(environ, start_response)

WSGIScriptAlias /trac /usr/src/trac/apache/trac.wsgi
