Installation de Gitlab

• Gitlab évoluant rapidement, il est difficile de maintenir un script d'installation/mise à jour. Il est plus simple pour l'installer de suivre le tutoriel d'installation pas à pas pour Debian.
  • Préalablement, créer une base de données Mysql comme indiqué sur le site de GitLab.
  • L'installation originelle de Gitlab sur Yilgarn a été réalisé en suivant les indications présentes dans le script gitlab.sh (voir ci-dessous)
• Pour basculer le site hébergent Gitlab en HTTPS, suivre les indication concernant l'utilisation de HTTPS.

• Pour voir la version installer : cat /home/git/gitlab/VERSION
• Pour les versions majeures rechercher votre version dans la liste des procédures de mise à jour.
• Pour les mises à jour mineures suivre les indication pour patcher une version.

• Se placer dans le dossier /home/git/gitlab : cd /home/git/gitlab
• Lancer les commandes :
  • sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production
  • sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production

• service gitlab-workhorse restart
• service gitlab-unicorn restart
• service gitlab-sidekiq restart
• service redis-server restart : doit fonctionner pendant l'opération de backup de Gitlab.

• Trouble-Shooting-Guide

• Ne pas modifier le fichier de conf Nginx du site Gitlab pour le support de SSL
  • ajouter cette ligne pour permettre la vérification par Certbot : location ^~ /.well-known { root /home/git/gitlab/public; }
• Lancer Certbot en root : certbot certonly –webroot -w /home/git/gitlab/public -d git.clapas.org
• Ajouter dans le fichier de conf Nginx du site Gitlab le support de SSL & HTTP2
• Et laisser la ligne pour la vérification par Certbot : location ^~ /.well-known { root /home/git/gitlab/public; }

• Si le service gitlab-unicorn ne veut pas démarrer à cause de ses dépendance, vérifier que le service redis-server est bien démarré.
• Si le service redis-server ne veut pas démarrer, vérifier que le dossier /var/run/redis existe bien avec les bons droits.

Vérifier que mysqldump est accessible. Vérifier la présence d'un lien vers la bonne version de Mysql dans /usr/local/bin .

• Si le message suivant survient “Some gems seem to be missing from your vendor/cache directory.”, essayer la commande suivante, pour réinstaller les paquets en local : sudo -u git -H bundle
• Pour remettre à plat Bundle :
  • gem update –system
  • gem update bundler

• Désactiver le cache dans le fichier : /home/git/gitlab/config/environments/production.rb
• Modifier le paramètre suivant : config.cache_classes = false
