 # Installation
 
-## Installation des dépendances
+Un tutoriel pour installer le projet est disponible [sur le wiki](https://gitlab.federez.net/federez/re2o/wikis/User%20Documentation/Quick%20Start).
 
-L'installation comporte 3 partie : le serveur web où se trouve le depot re2o
-ainsi que toutes ses dépendances, le serveur bdd (mysql ou pgsql) et le 
-serveur ldap. Ces 3 serveurs peuvent en réalité être la même machine, ou séparés
-(recommandé en production).
-Le serveur web sera nommé serveur A, le serveur bdd serveur B et le serveur ldap
-serveur C.
-
-### Prérequis sur le serveur A
-
-Voici la liste des dépendances à installer sur le serveur principal (A).
-
-### Avec apt :
-
-#### Sous debian 9
-
-Paquets obligatoires:
- * python3-django (1.10, stretch)
- * python3-dateutil (stretch)
- * texlive-latex-base (stretch)
- * texlive-fonts-recommended (strech)
- * python3-djangorestframework (stretch)
- * python3-django-reversion (stretch)
- * python3-pip (stretch)
-
-Paquet recommandés:
- * python3-django-extensions (stretch)
-
-
-### Autres dépendances : 
-
-Paquets préalables à installer avec apt : 
- * libsasl2-dev (stable)
- * libldap2-dev (stable)
- * libssl-dev (stable)
-
-Avec pip3 (pip3 install):
- * django-bootstrap3
- * django-ldapdb
- * django-macaddress
-
-Moteur de db conseillé (mysql), postgresql fonctionne également.
-Pour mysql, il faut installer : 
- * python3-mysqldb
- * mysql-client
-
-### Prérequis sur le serveur B
-
-Sur le serveur B, installer mysql ou postgresql, dans la version stretch.
- * mysql-server (stretch) ou postgresql (stretch)
-
-### Prérequis sur le serveur C
-Sur le serveur C (ldap), avec apt :
- * slapd (stretch)
-
-### Installation sur le serveur principal A
-
-Cloner le dépot re2o à partir du gitlab, par exemple dans /var/www/re2o.
-Ensuite, il faut créer le fichier settings_local.py dans le sous dossier re2o, 
-un settings_local.example.py est présent. Les options sont commentées, et des 
-options par défaut existent.
-
-En particulier, il est nécessaire de générer un login/mdp admin pour le ldap et 
-un login/mdp pour l'utilisateur sql (cf ci-dessous), à mettre dans 
-settings_local.py
-
-### Installation du serveur mysql/postgresql sur B
-
-Sur le serveur mysql ou postgresl, il est nécessaire de créer une base de 
-donnée re2o, ainsi qu'un user re2o et un mot de passe associé. 
-Ne pas oublier de faire écouter le serveur mysql ou postgresql avec les acl 
-nécessaire pour que A puisse l'utiliser.
-
-#### Mysql
-Voici les étapes à éxecuter pour mysql :
- * CREATE DATABASE re2o collate='utf8_general_ci';
- * CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';
- * GRANT ALL PRIVILEGES ON re2o.* TO 'newuser'@'localhost';
- * FLUSH PRIVILEGES;
-
-#### Postgresql
- * CREATE DATABASE re2o ENCODING 'UTF8' LC_COLLATE='fr_FR.UTF-8' 
-LC_CTYPE='fr_FR.UTF-8';
- * CREATE USER newuser with password 'password';
- * ALTER DATABASE re2o owner to newuser;
-
-Si les serveurs A et B ne sont pas la même machine, il est nécessaire de 
-remplacer localhost par l'ip avec laquelle A contacte B dans les commandes 
-du dessus.
-Une fois ces commandes effectuées, ne pas oublier de vérifier que newuser et 
-password sont présents dans settings_local.py
-
-### Installation du serveur ldap sur le serveur C
-
-Ceci se fait en plusieurs étapes : 
- * générer un login/mdp administrateur (par example mkpasswd sous debian)
- * Copier depuis re2o/install_utils (dans le dépot re2o) les fichiers db.ldiff 
-et schema.ldiff (normalement sur le serveur A) sur le serveur C 
-(par ex dans /tmp)
- * Hasher le mot de passe généré en utilisant la commande slappasswd 
-(installée par slapd)
- * Remplacer toutes les sections FILL_IN par le hash dans schema.ldiff et 
-db.ldiff
- * Remplacer dans schema.ldiff et db.ldiff 'dc=example,dc=org' par le 
-suffixe de l'organisation
- * Arréter slapd
- * Supprimer les données existantes : '''rm -rf /etc/ldap/slapd.d/*''' et 
-'''rm -rf /var/lib/ldap/*'''
- * Injecter le nouveau schéma : 
-'''slapadd -n 0 -l schema.ldiff -F /etc/ldap/slapd.d/''' et 
-'''slapadd -n 1 -l db.ldiff'''
- * Réparer les permissions (chown -R openldap:openldap /etc/ldap/slapd.d et
-chown -R openldap:openldap /var/lib/ldap) puis relancer slapd
-
-Pour visualiser et éditer le ldap, l'utilisation de shelldap est fortement
-recommandée, en utilisant en binddn et basedn tous deux égaux à 'cn=config' et
-binddpw le mot de passe admin.
-
-Rajouter (exemple de chemin de fichier avec un certif LE):
-`olcTLSCertificateKeyFile: /etc/letsencrypt/live/HOSTNAME/privkey.pem
-olcTLSCACertificateFile: /etc/letsencrypt/live/HOSTNAME/chain.pem
-olcTLSCertificateFile: /etc/letsencrypt/live/HOSTNAME/cert.pem `
-
-Mettre à jour la partie ldap du `settings_local.py` (mettre 'TLS' à True
-si besoin, user cn=config,dc=example,dc=org et mot de passe
-ldap choisi précédemment).
-
-## Configuration initiale
-
-Normalement à cette étape, le ldap et la bdd sql sont configurées correctement.
-
-Il faut alors lancer dans le dépot re2o '''python3 manage.py migrate''' qui
-va structurer initialement la base de données.
-Les migrations sont normalement comitées au fur et à mesure, néanmoins cette
-étape peut crasher, merci de reporter les bugs.
-
-## Démarer le site web
-
-Il faut utiliser un moteur pour servir le site web. Nginx ou apache2 sont 
-recommandés.
-Pour apache2 :
- * apt install apache2
- * apt install libapache2-mod-wsgi-py3 (pour le module wsgi)
-
-Un example de site apache2 se trouve dans install_utils ( re2o.conf)
-re2o/wsgi.py permet de fonctionner avec apache2 en production
-
-## Configuration avancée
-
-Une fois démaré, le site web devrait être accessible. 
-Pour créer un premier user, faire '''python3 manage.py createsuperuser''' 
-qui va alors créer un user admin.
-Il est conseillé de créer un user portant le nom de
-l'association/organisation, qui possedera l'ensemble des machines, à indiquer
-dans le menu reglages sur l'interface.
-
