Virtual hosts

Let's say you want to host domains first.com and second.com.

Create folders for their files:

Leimi

#!/usr/bin/env node
var fs = require('fs');
var path = require('path');
var sass = require('node-sass');
var ENV = process.env.SASS_ENV || 'development';

var file = 'variables.scss';

//if in dev, directly pass file to sass
if (ENV === "development") {

pvencill

var ldap = require('ldapjs');
var ssha = require('node-ssha256');


var BASE = 'ou=Users,dc=example,dc=org';
// default port for ldaps
var URL = 'ldaps://ldap.example.org/:636';


// user and pass are for existing user with rights to add a user

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
