I am trying to install on RHLE 4 using: python 2.6.5 pysqlite 2.5.6 sqlite3 3.3.13 Trac 0.12.1

I created a project,when I use browser to access the project,it displayd:

TimeoutError: Unable to get database connection within 0 seconds.
TracError(u'The user daemon requires read _and_ write permissions to the database file /var/www/trac/test/db/trac.db and the directory it is located in.',)

How can I to deal it?

This is an InstallationIssue. I would start by following the advice on the last line (although I'm not sure what the "user daemon" is, there's no such thing in Trac core).
