Installation de loggerhead & co sur une debian
=============================================================

Variables
-------------
::

    bzr=/var/bzr
    repos=$bzr/repos

Apache
--------
- Groupe Apache::

    groupadd bzr
    for i in sra mpa www-data; do
        gpasswd -a $i  bzr
    done

Repositories container creation
--------------------------------
::

    mkdir $bzr
    cd $bzr
    mkdir env repos python
    chown root:bzr env repos python
    chmod 755 env repoos python
    ln -sf /var/bzr/repos/ /bzr

Idea
-------
::

    Repos/              rwxr-x---     root:bzr
        tri1/           rwxr-x---     tri1:bzr
        tri2/           rwxr-x---     tri2:bzr

Fix repo rights
------------------
::

    cd $bzr/repos
    for trigramme in *;do
        chown -Rf $trigramme:bzr $trigramme
        chmod -Rf 750 $trigramme
    done

Add a developper repo
------------------------
Rely on ldap auth. for users creation::

    mkdir $bzr/repos/$trigramme
    gpasswd -a $trigramme bzr
    chown -Rf $trigramme:bzr $trigramme
    chmod -Rf 750 $trigramme

Install root repo
------------------------------------
Got a python bootstrapper and letz rule::

    apt-get install build-essential m4 libtool pkg-config autoconf m4 gettext bzip2
    cd $bzr
    wget http://hg.minitage.org/hg/minitage/shell/raw-file/tip/PyBootstrapper.sh
    bash ./PyBootstrapper.sh python
    python/bin/virtualenv --no-site-packages env
    source env/bin/activate
    # bootstrap, puis install en dev pour bzr-svn
    mkdir bzr.repos
    cd bzr.repos
    easy_install paramiko
    easy_install Pyrex
    easy_install bzr
    bzr branch lp:loggerhead
    cd $bzr/bzr.repos/loggerhead && easy_install .
    easy_install http://www.owlfish.com/software/simpleTAL/downloads/SimpleTAL-4.1.tar.gz
    easy_install Paste


Add a cron job to reset rights
--------------------------------
log as root::

    crontab -e #and add
    * */15 * * * /var/bzr/bin/fix_rights.sh

Add a basic init script to start loggerhead
---------------------------------------------
::

    #!/bin/sh
    #
    # Loggerhead start/stop script.


    host="bzr.makina-nantes.net"
    port="8443"
    prefix="/var/bzr"
    repos="$prefix/repos"
    log_folder="$prefix/var/log"
    start_cmd="$prefix/env/bin/serve-branches --port $port --host $host $repos --log-folder=$log_folder"
    pid_file="$prefix/var/run/loggerhead.pid"
    user="www-data"
    py="$prefix/env/bin/python"
    server_name="Loggerhead"

    start() {
            echo "Starting $server_name server"
            start-stop-daemon --start  -c $user  --quiet --background\
            -p $pid_file -m  --exec "$py"  --  $start_cmd
    }

    stop() {
            echo  "Stopping $server_name  server"
            start-stop-daemon --stop --user $user  \
            -p $pid_file
    }


    case "$1" in
      'start')
            start
            ;;
      'stop')
            stop
            ;;
      'restart')
            stop
            start
            ;;
      *)
            echo "usage: $0 start|stop|restart"
            exit 1
            ;;
    esac
    #vim:set ft=bash:

Add apache vhost
-----------------
Add modrewrite and proxy::

    a2enmod rewrite proxy proxy_http
    apt-get install libapache2-mod-proxy-html
    a2enmod    proxy_html
    /etc/init.d/apache2 force-reload

Add the vhost::

    # /etc/apache2/sites-available/100-bzr
    <VirtualHost *>
