Setup an EC2 instance with Ubuntu (14.04)
Open port 8080

Install Jenkins
wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -
sudo sh -c 'echo deb http://pkg.jenkins-ci.org/debian binary/ > /etc/apt/sources.list.d/jenkins.list'
sudo apt-get update
sudo apt-get install jenkins
http://<host>:8080 -> you should see Jenkns running.

Setup nginx on port 80

sudo aptitude -y install nginx
cd /etc/nginx/sites-available
sudo rm default ../sites-enabled/default

Copy & save into /etc/nginx/sites-available/jenkins:

# Configuration for nginx
upstream app_server {
    server 127.0.0.1:8080 fail_timeout=0;
}

server {
    listen 80;
    listen [::]:80 default ipv6only=on;
    server_name ci.yourcompany.com;

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;

        if (!-f $request_filename) {
            proxy_pass http://app_server;
            break;
        }
    }
}
# End nginx configuration

sudo ln -s /etc/nginx/sites-available/jenkins /etc/nginx/sites-enabled/
sudo service nginx restart

Open port 80 in the security group and close 8080.
