GitLab 6 sur scientific linux 6.3 (globalement EL6)

Gitlab est une application de gestion de dépôts git sous licence MIT.

Elle permet d'héberger sur votre propre serveur des dépôts git avec l'interface web offrant tout le nécessaire pour vos projets : navigation dans le code source, suivi des demandes de bugs et d'évolutions (« issues »), wiki, gestion des droits d'accès par équipe, commentaires, notifications, etc.

On le décris souvent (à tort) comme un fork "open-source" de GitHub.

Je vais vous présenter 2 façons de l' installer, la première avec Bitnami (installation "1 clic" ) et la seconde sera un script d'installation.

Installation Gitlab 6.0 avec Bitnami :

Bitnami permet l'installation de Gitlab (et d'autres..) "en 1 clic" tout en nous proposant de configurer le répertoire de destination et quelques configurations de base.

Bitnami va "packager" tout l'ensemble de l'installation dans un répertoire (outils, programmes tel qu'apache, ruby...) évitant ainsi une interaction néfaste sur d'autres programmes installés sur la machine.

La page de téléchargement de Gitlab se trouve ici :

http://bitnami.com/stack/gitlab/installer

Une fois le téléchargement effectué :

chmod +x ./bitnami-gitlab-6.0.0-0-linux-x64-installer.run

puis :

./bitnami-gitlab-6.0.0-0-linux-x64-installer.run --mode text

L'installation se poursuit :

L'installation est terminée, pour d'autres réglages (LDAP, SMTP) aller à la fin du tuto.

Installation Gitlab 6.0 avec script :

Si vous préférez une installation de type script en voilà une :

(testé sur machine "propre")

   
#!/bin/bash
# Installer for GitLab on RHEL 6 (Red Hat Enterprise Linux and CentOS)
#

##Export proxy settings


# Define the public hostname
export GL_HOSTNAME=$HOSTNAME

# Install from this GitLab branch
export GL_GIT_BRANCH="6-0-stable"

## Install epel-release
yum -y install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

# Exit on error

die()
{
  # $1 - the exit code
  # $2 $... - the message string

  retcode=$1
  shift
  printf >&2 "%s\n" "$@"
  exit $retcode
}

echo "### Check OS (we check if the kernel release contains el6)"
uname -r | grep "el6" || die 1 "Not RHEL or CentOS 6 (el6)"

passe rarement, donc modifier le fichier à la main :-)

Configuration LDAP :

Afin de configurer l'authentification LDAP, modifier le fichier gitlab.yml.

cd /opt/gitlab-6.0.0-0/apps/gitlab/htdocs/config/
nano gitlab.yml

Configuration SMTP :

Afin de recevoir des notifications (mails) lors de changements sur un repository, de création d'"issue", de commits.., il convient de configurer gitlab afin qu'il puisse utiliser le serveur SMTP interne. Configuration de gitlab.yml :

nano /opt/gitlab-6.0.0/apps/gitlab/htdocs/config/gitlab.yml

puis :

nano /opt/gitlab-6.0.0/apps/gitlab/htdocs/config/environements/production.rb
