2. Dowload ruby source code 1. Visit official website of ruby and find the latest ruby version. The current version is 1.9.3-p362. 2. Run wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p362.tar.gz

   1. cd ruby-1.9.3-p362
   2. Configure. Run ./configure --prefix=/opt/ruby/1.9.3-p362 --enable-pthread --enable-shared. This will install ruby in /opt/ruby/1.9.3-p362
   3. Make. Just run make in the ruby source code directory
   4. Install ruby. Run sudo make install 3. Add links to your bin directory

     sudo ln -s /opt/ruby/1.9.3-p362/ruby /usr/local/bin/ruby
     sudo ln -s /opt/ruby/1.9.3-p362/rake /usr/local/bin/rake
     sudo ln -s /opt/ruby/1.9.3-p362/irb /usr/local/bin/irb
     sudo ln -s /opt/ruby/1.9.3-p362/gem /usr/local/bin/gem
   

4. Install "bundle" gem
  1. Run `sudo gem install bundle`
  2. Add "bundle" to bin directory, `sudo ln -s /opt/ruby/1.9.3-p362/bundle /usr/local/bin/bundle`

Install the Project

1. Get the codes, and put them into /srv directory, for example I put them into /srv/sftp_monitor_spark/. The structure of the project is under below.

```
  |--config
  |  |--config.yml
  |  |--user.yml
  |--lib
  |  |--x_log.rb
  |--public
  |  |--CSS and JS here
  |--views
  |  |--schedules
  |  |--layout.erb
  |  |--logs.erb
  |  |--new.erb
  |  |--sections.erb
  |--aplication.rb
  |--config.ru
  |--config.yml
  |--Gemfile
  |--README.md
```

2. Edit the basic settings 1. Copy the example file to your own file

     cp config/config.example.yml config/config.yml
     cp config/user.example.yml config/user.yml
   

2. Edit the lines #2~5 in config/config.yml to set where are your files. Attention, the `ini`, `schedule` and `lock_file` should be put into the same diretory as scripts.
3. Edit config/user.yml to set HTTP authentication name and password of your own.

3. Install the necessary ruby gems. In the project directory, run bundle install

Test the Project

1. Run ruby application.rb -e production in project directory. This will start the program on your localhost with port 4567 as default * Here are some other options for this command ruby application.rb [-h] [-x] [-e ENVIRONMENT] [-p PORT] [-o HOST] [-s HANDLER] * More detailed description for the options: ruby application --help
2. Visit http://localhost:4567 in your browser

Deploy in Production Model with Nginx

1. Make sure your port is available. For example, if you plan to use Port 3000, you can run sudo netstat -ltnp | grep ':3000' to see whether Port 3000 is being used by other process.
2. Install Nigix with Passenger. During the installation, select the default configurations.

```
  sudo gem install passenger
  sudo /opt/ruby/1.9.3-p362/bin/passenger-install-nginx-module
```

3. Add Nginx to service and start up auto run list

```
  wget https://raw.github.com/gist/1548664/53f6d7ccb9dfc82a50c95e9f6e2e60dc59e4c2fb/nginx
  sudo cp nginx /etc/init.d/
  sudo chmod +x /etc/init.d/nginx
  sudo update-rc.d nginx defaults
```

4. Configure Nginx 1. Edit the Nginx configuration file (/opt/nginx/conf/nginx.conf)

     server {
     listen       3000;
     server_name  localhost;
   
     location / {
     root /srv/sftp_monitor_spark/public;
     passenger_enabled on;
     }
   

2. Restart Nginx

  Run `sudo service nginx restart`
