Trac & Nginx on Ubuntu Feisty
Install trac
apt-get install trac python-mysqldb
Update ClearSilver
https://bugs.launchpad.net/ubuntu/+source/clearsilver/+bug/114930
apt-get install python-dev
wget http://www.clearsilver.net/downloads/clearsilver-0.10.5.tar.gz
tar xvzf clearsilver-0.10.5.tar.gz
cd clearsilver-0.10.5/
./configure –disable-wdb –disable-compression –disable-perl –with-python=$(which python)
make
cd python
cp -i neo_cgi.so /usr/lib/python2.5/site-packages/neo_cgi.so
Trac Environments Directory
You’ll need a directory for Trac’s environments to live that should be writable by the default tracd user:
sudo mkdir /var/lib/trac
sudo chgrp users /var/lib/trac
Create a MySQL DB
Create a new database (trac) and user with full rights to that DB (trac). Make sure the database character set is latin1_bin (UTF8 will cause key length problems; throwing “Specified key was too long; max key length is 1000 bytes” errors during trac setup)
Your connection string will be:
mysql://trac:trac@hostname:port/databasename
Configure Trac
trac-admin /var/lib/trac initenv
Follow the instructions.
Correct locale errors
If you get locale errors:
apt-get install localeconf
localedef -i en_US -c -f UTF-8 en_US.UTF-8

Get Symfony
# pear channel-discover pear.symfony-project.com

$php_dir/symfony/ /usr/share/php/symfony/ main libraries
$data_dir/symfony/ /usr/share/php/data/symfony/ skeleton of symfony applications, default modules and configuration
doc_dir/symfony/ /usr/share/php/docs/symfony/ documentationCreate / configure a new symfony application
# mkdir /var/www/myproject
# cd /var/www/myproject
# symfony init-project myproject
# symfony init-app myapp
# ln -s /etc/nginx/sites-available/wattprint.org /etc/nginx/sites-enabled/wattprint.org
# /etc/init.d/nginx restart
