Skyhopper on Ubuntu Environment

Hey Guys, I guess you want to checkout and install SkyHopper on your local PC or on an EC2 server with Ubuntu which is a Debian based Linux OS. The purpose of this is to checkout SkyHopper to another linux based OS as currenlty, we only support Amazon Linux for the installation instruction.

Now, here are some tips and instruction when installing the service into Ubuntu Version 14.04 LTS Client or server.

First is to remove old ruby version and upgrade it to version 2.2.4. Please careful not to over-upgrade it a more higher version as it will have dependency problems in the future. As of now we would only use Ruby version 2.2.4

sudo apt-get remove ruby

The next step is to install some dependencies for Ruby.

sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev libffi-dev

Next we’re going to be installing Ruby using rbenv. Take note that there are other ways to install ruby that have their own benefits, most people prefer using rbenv these days, but if you’re familiar with rvm you can install using that method as you please. But for now I will just use rbenv.

Installing with rbenv is a simple two step process. First you install rbenv, and then ruby-build:

git clone git:// .rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL

git clone git:// ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL

rbenv install 2.2.4
rbenv global 2.2.4
ruby -v


Install bundler using gem to get out from dependency hell, and ensures that the gems you need are present.

gem install bundler

Install nodejs and npm for frontend dependencies

sudo apt-get install nodejs nodejs-legacy npm 

Install bower using npm

sudo npm install bower --global

Install necessary development libraries needed 

sudo apt-get install libreadline-gplv2-dev libncurses5-dev zlib-devel ncurses-devel libssl-dev libmysqlclient-dev

Install MySQL Server

To install MySQL, run the following command from a terminal prompt:

sudo apt-get install mysql-server

During the installation process you will be prompted to enter a password for the MySQL root user.

Once the installation is complete, the MySQL server should be started automatically. You can run the following command from a terminal prompt to check whether the MySQL server is running:

sudo netstat -tap | grep mysql

When you run this command, you should see the following line or something similar:

tcp        0      0 localhost:mysql         *:*                LISTEN      2556/mysqld

If the server is not running correctly, you can type the following command to start it:

sudo service mysql restart

Then we need to Install Redis


To install redis, please follow the instruction written here:

Install nginx for websockets, traffic hosting and handling to be used in SkyHopper System.

sudo apt-get install nginx

You will probably be prompted for your user’s password. Enter it to confirm that you wish to complete the installation. The appropriate software will be downloaded to your server and then automatically installed.

We can make sure that our web server will restart automatically when the server is rebooted by typing:

sudo update-rc.d nginx defaults

Then we need to remove the default variable of nginx to replace it with SkyHopper 

sudo rm /etc/nginx/sites-available/default

Then copy the reverse proxy to setup nginx. You might need to change some variables written as it needs to correspond to your skyhopper setup, for example the directory of your skyhopper files are located.

$ sudo tee /etc/nginx/conf.d/skyhopper.conf <<EOF >/dev/null
server {
        listen 80;
        server_name skyhopper.local; #Setup Environment

        ### Production only runs here ###
        location ~ ^/(assets|fonts) {
          root /home/ec2-user/skyhopper/public; # The location of skyhopper cloned directory
        ### Only when running production environment ###

        location / {
            proxy_set_header    X-Real-IP   \$remote_addr;
            proxy_set_header    Host    \$http_host;

        location /ws {
            proxy_http_version 1.1;
            proxy_set_header    Upgrade \$http_upgrade;
            proxy_set_header    Connection "upgrade";
            proxy_set_header    Host    \$http_host;

Downloading/Cloning SkyHopper from GitHub

$ cd ~ #the directory where you want to install SkyHopper
$ git clone

Up to this point it can be executed by Chef.

Creating MySQL user

$ mysql -uroot


mysql> CREATE USER 'skyhopper_dev'@'localhost' IDENTIFIED BY 'your_dev_password';
mysql> GRANT CREATE, SHOW DATABASES ON *.* TO 'skyhopper_dev'@'localhost';
mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, LOCK TABLES ON `SkyHopperDevelopment`.* TO 'skyhopper_dev'@'localhost';
mysql> exit


mysql> SET storage_engine=INNODB;
mysql> CREATE USER 'skyhopper_prod'@'localhost' IDENTIFIED BY 'your_prod_password';
mysql> CREATE DATABASE IF NOT EXISTS `SkyHopperProduction` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;
mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, LOCK TABLES ON `SkyHopperProduction`.* TO 'skyhopper_prod'@'localhost';
mysql> exit

SkyHopper Setup
