how to setup gitorious on ubuntu server 11.10

how to setup gitorious on ubuntu server 11.10:
In this tutorial I will describe how to setup gitorious on Ubuntu 11.10. Gitorious – a Ruby on Rails web application – can be used to conclude git projects in an easy to manage user interface. In the README of the gitorious repository I found the evidence “One of the main challenges in Gitorious is its installation process. It is anything but trivial.” – It appears correct ;) During the installation I got some errors by the sphinx search engine and some ruby gems. You will find the workarounds in this tutorial.



This tutorial is based on the gitorious – UbuntuInstallation tutorial.
In this setup I will use the hostname gitorious.linux-adm.de – change this hostname in your installation.


software installation



Required packages


apt-get install build-essential zlib1g-dev tcl-dev libexpat-dev \
    libcurl4-openssl-dev postfix apache2 mysql-server mysql-client \
    apg geoip-bin libgeoip1 libgeoip-dev sqlite3 libsqlite3-dev \
    imagemagick libpcre3 libpcre3-dev zlib1g zlib1g-dev libyaml-dev \
    libmysqlclient15-dev apache2-dev libonig-dev ruby-dev rubygems \
    libopenssl-ruby phpmyadmin libdbd-mysql-ruby libmysql-ruby \
    libmagick++-dev  zip unzip memcached git-core git-svn git-doc \
    git-cvs irb libxslt1.1 libxslt1-dev


Ruby, sphinxsearch, stompserver


apt-get install libchronic-ruby librmagick-ruby libdaemons-ruby \
ruby-hoe ruby-echoe libyadis-ruby ruby-mime-types libopenid-ruby \
libdifflcs-ruby libjson-ruby librack-ruby libhmac-ruby rake stompserver \
libapache2-mod-passenger rails sphinxsearch sphinxbase-utils


fetch gitorious


git clone git://gitorious.org/gitorious/mainline.git /var/www/gitorious

install missing ruby gems
cd /var/www/gitorious/
gem install bundler
bundle install


git user


Create a git user with the homedir in /var/www/gitorious/ and set the correct ownership. 
adduser --system --home /var/www/gitorious/ --no-create-home --group --shell /bin/bash git
chown git:git -R /var/www/gitorious/

Create a directory for the repositories and a cache directory. Gitorious will add the SSH public keys of the registered users to the authorized_keys file, therefore we have to create a .ssh file and an empty authorized_keys file with the correct permissions.
su - git
git submodule init && \
git submodule update
mkdir -p tmp/pids
mkdir repositories
mkdir tarballs
mkdir .ssh
touch .ssh/authorized_keys
chmod 700 .ssh/
chmod 600 .ssh/authorized_keys

Put gitorious binary on path:
cat >> /var/www/gitorious/.bash_profile <<EOF
export PATH="$PATH:/var/www/gitorious/script/"
EOF


gitorious configuration



prepare configuration files


cd /var/www/gitorious
cp config/database.sample.yml config/database.yml
cp config/gitorious.sample.yml config/gitorious.yml
cp config/broker.yml.example config/broker.yml


create a secret key


Create a secret key for the session cookie. (we need this key later in the next step.
apg -m 32


setup config/gitorious.yml


Setup gitorious in /var/www/gitorious/config/gitorious.yml:


repository_base_path: "/var/www/gitorious/repositories"
cookie_secret: xxx # add a secret key here the command "apg -m 32"
gitorious_client_port should be 80
gitorious_host: gitorious.linux-adm.de # change to your hostname
archive_cache_dir: "/var/www/gitorious/tarballs"
archive_work_dir: "/tmp/tarballs-work"
hide_http_clone_urls: true
is_gitorious_dot_org: false


Create the logroate configuration and the init scripts.
cp /var/www/gitorious/doc/templates/ubuntu/gitorious-logrotate /etc/logrotate.d/

cp /var/www/gitorious/doc/templates/ubuntu/git-ultrasphinx /etc/init.d/
cp /var/www/gitorious/doc/templates/ubuntu/git-daemon /etc/init.d/
cp /var/www/gitorious/doc/templates/ubuntu/git-poller /etc/init.d/

Set in /etc/init.d/git-daemon and in /etc/init.d/git-poller the RUBY_HOME variable to “/usr”



#RUBY_HOME="/opt/ruby-enterprise"

RUBY_HOME="/usr"


Activate the new gitorious init scripts
update-rc.d git-daemon defaults && \
    update-rc.d git-poller defaults && \
    update-rc.d git-ultrasphinx defaults


fix gem spec files


Try to start /etc/init.d/git-ultrasphinx

If you get the following error message you have to fix the spec files:
root@ubuntu03:/var/www/gitorious# /etc/init.d/git-ultrasphinx start

Change the “s.date” in the following spec files:
/var/lib/gems/1.8/specifications/json-1.5.4.gemspec

/var/lib/gems/1.8/specifications/childprocess-0.2.1.gemspec

in:



s.date = %q{2012-08-31}



fix git-ultrasphinx


You have to fix the /var/www/gitorious/config/boot.rb file,

if you get the following error message after starting /etc/init.d/git-ultrasphinx.
