Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

RVM and Ruby

apt-get -yqq install libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion pkg-config curl build-essential git

su - vagrant -c "sudo bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)"
adduser vagrant rvm
source /etc/profile.d/rvm.sh
su - vagrant -c "rvm pkg install libyaml"
su - vagrant -c "rvm install 2.0.0-turbo"

su - vagrant -c "rvm use 2.0.0-turbo --default"

Postgres

Configure so that the vagrant user doesn't need to provide username and password.

apt-get -yqq install postgresql postgresql-contrib-9.3 libpq-dev postgresql-server-dev-9.3

psql -c "ALTER USER vagrant WITH PASSWORD 'password';"
psql -c "create database discourse_development owner vagrant encoding 'UTF8' TEMPLATE template0;"

psql -c "create database discourse_test owner vagrant encoding 'UTF8' TEMPLATE template0;"
