Gitolite

SETUP: Create git user & install gitolite

sudo apt-get install openssh-server 

sudo adduser \
  --system \
  --shell /bin/sh \
  --gecos 'git version control' \
  --group \
  --disabled-password \
  --home /home/git \
  git

# Add your user to git group
sudo usermod -a -G git `eval whoami` 

# copy your pub key to git home
sudo cp ~/.ssh/id_rsa.pub /home/git/rails.pub

# clone gitolite
sudo -u git -H git clone git://github.com/gitlabhq/gitolite /home/git/gitolite

# install gitolite
sudo -u git -H /home/git/gitolite/src/gl-system-install

# Setup (Dont forget to set umask as 0007!!)
sudo -u git -H sh -c "PATH=/home/git/bin:$PATH; gl-setup ~/rails.pub"

sudo chmod -R g+rwX /home/git/repositories/
sudo chown -R git:git /home/git/repositories/

CHECK: Logout & login again to apply git group to your user

# clone admin repo to add localhost to known_hosts
# & be sure your user has access to gitolite
git clone git@localhost:gitolite-admin.git /tmp/gitolite-admin 

# if succeed  you can remote it
rm -rf /tmp/gitolite-admin 

IMPORTANT: Be sure you've set repository umask to 0007 in /home/git/.gitolite.rc
