Etherpad

Présentation d'installation d'un serveur EtherPad sur debian 9.
Dans cette présentation, nous allons configurer un site https://pad.sleto.net.

Nous utiliserons les variables DBNAME, DBUSER et DBPASSWD respectivement pour le nom, l'utilisateur et le mot de passe de base de données.

Dépendances

Utilise un Serveur web sécurisé (Nginx / Let's Encrypt).
Nécessite également les outils :

sudo apt-get install -y postgresql postgresql-contrib supervisor git

Vous devrez également ajouter le domaine pad.sleto.net dans le Serveur DNS (bind9)

Base de données

Nous allons créé une base de donnée PostgreSQL:

sudo -u postgres psql -c "CREATE USER $DBUSER;"
sudo -u postgres psql -c "ALTER USER $DBUSER PASSWORD '$DBPASSWD';"
sudo -u postgres psql -c "CREATE DATABASE $DBNAME OWNER $DBUSER;"

Pré-configuration

Création d'un utilisateur etherpad:

adduser --system --home /opt/etherpad --shell /bin/bash --disabled-password --quiet etherpad
install -d -m 755 -o $DBUSER /opt/etherpad

Installation

Ecrire le fichier /tmp/settings.json (attention de bien remplacer $DBNAME, $DBUSER et $DBPASSWD):

    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;

    location / {
        proxy_pass http://localhost:9001;

        proxy_redirect off;
        proxy_set_header        Upgrade           $http_upgrade;
        proxy_set_header        Connection        "upgrade";
