  • gem install passenger
  • passenger-install-apache2-module

i followed the steps that the installer told me and go. just needed to apt-get some apache dev packages and was ready to run.

cant tell you how happy i am.

now the rails fun can start.

first step: download ruby. execute the usual ./configure && make && make install triplet. worked fine. then download ruby gems. but when i tried to run anything with gem i got:


/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- zlib (LoadError)
from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'

from /usr/local/lib/ruby/site_ruby/1.8/rubygems/gem_runner.rb:58:in `run'
from /usr/local/bin/gem:21

after googleing and trying some stuff i solved it this way:

  • edit ruby-1.9.1-p0/ext/Setup
  • uncomment the line zlib
  • make && make install again

next step. successfully let gem install rails. but then ruby script/server stopped with:


=> Booting WEBrick
=> Rails 2.3.4 application starting on http://0.0.0.0:3000
/usr/local/lib/ruby/gems/1.9.1/gems/rails-2.3.4/lib/initializer.rb:271:in `rescue in require_frameworks': no such file to load -- openssl (RuntimeError)

from script/server:3:in `require'

'

after a another round i found this site with help:

  • apt-get install openssl libssl-dev
  • apt-get install ruby1.9-dev
  • cd ruby-1.9.1-p129/ext/openssl
  • ruby extconf.rb
  • make && make install

that worked. nice. so now i am waiting for the next fail

so because my webserver is a debian system the installations first steps where easy:

apt-get install trac

after that trac is installed in /usr/share/trac. to create your trac-environment you have to call the admin console program from trac:

trac-admin /var/www/trac initenv

where /var/www/trac is the place where your website will go and initenv is the command to tell trac-admin to initialise a new environment. next i setup apache to serve the new site. there are a bunch of possibilities to let apache server trac: cgi, fastcgi, mod_python etc. i tried cgi and fastcgi first but the mod_python version worked at last. so i need to install mod_phyton:

apt-get install libapache-mod-python

ok got some tips for the site config out of the net. here is my virtualhost-config part:

# Trac Configuration
<VirtualHost *>
ServerName wop.dotob.de
DocumentRoot /var/www/trac/
<Location / >
SetHandler mod_python
PythonHandler trac.web.modpython_frontend
PythonInterpreter main_interpreter
PythonOption TracEnv /var/www/trac/
PythonOption TracUriRoot /
AuthType Basic
AuthName “trac”
# Use the SVN password file.
AuthUserFile /var/svn/.dav_svn.passwd
Require valid-user
</Location>
</VirtualHost>

sorry i assumed you have set your subversion on the same server an it is already up but i wont tell how this is done here. thats said: the /var/svn/.dav_svn.passwd is my subversion authentication file. i use the svn authentication for trac too.

well now trac is up and running. you can use trac-admin, which is a great commandline tool with tab-completion and all to config stuff like when you create a ticket which level of severity are displayed or what the name of your milestones is. what i suggest also is to set some of the user permissions so you can change more stuff via the webinterface.

another thing i wanted is to let trac look into subversion commits an retrieve some information from my commit messages. so assume i have a ticket #5 and i check some fix for that. now i can write “fix #5 introduce new style in xaml” in the commit message and trac will close the ticket #5 with the svn version mentioned and the commit message attached. so how is this done:

subversion uses hook files to let users run scripts. so you go to your subversion repository (assume /var/svn/src) into the directory hooks. rename the post-commit.tmpl to post-commit. than that file is executed by subversion. now you need to insert the code from trac:

REPOS="$1"
REV="$2"
LOG=`svnlook log -r $REV $REPOS`
AUTHOR=`svnlook author -r $REV $REPOS`
TRAC_ENV='/var/www/woptrac'
/usr/bin/python /usr/share/doc/trac/contrib/trac-post-commit-hook -p "$TRAC_ENV" -r "$REV" -m "$LOG" -u "$AUTHOR"

i found some tutorials where the LOG part was missing but i couldnt get it to work without it. another thing that cost me a lot of time: when you write the commit it didnt work for me to write: “Fixes: #5″. i think the : between the command Fiexs and the #5 was not considered by the scripts regex.

i am curious about using trac. will tell how it behaves.
