Installing Ruby 1.9.2 & Rails 3 on Ubuntu with a single command

07 Mar

I wrote a script that installs Ruby 1.9.2 with RubyGems, Rails 3 and sqlite on Ubuntu with a single command. This script makes it very easy to get started developing Rails applications on Ubuntu. Its also an easy way for non-ruby developers to run popular Rails applications.

This is a script I originally wrote, a while ago for Ruby 1.8.7 and Rails 2, I recently realized that most of the traffic coming to my blog were people looking to setup Rails on Ubuntu. So I decided to update the script for Rails 3 and Ruby 1.9.2. So please enjoy.

I remember about 2 years ago, when I got kicked out of a shared hosting account because I was using too much CPU time, I was forced to move my high traffic web service to EC2. I was still new to Linux, it was my first time deploying a Rails app in production, and I was going to go live with thousands of users instantly. It was a nightmarish weekend. That’s why I write scripts like this, to help new users from Windows and OS X get comfortable with the Linux world.  Although Ubuntu 10 is much easier than 8.10, and Ruby 1.9.2 is a big improvement, Rails 3 with bundler is also a big relief, this is a script I wish I had 2 years ago while deploying my first Rails app.

Assumptions Made by the script

The script assumes you don’t have an older version of Ruby like (1.8.7) installed on the system. If you already have an older version of Ruby installed, use RVM instead of this script. To check if you have an older version of Ruby installed type

ruby -v

Installing and setting up Rails with a single command

Step 1: Install Git if you don’t already have it

 sudo apt-get install git-core

Step 2: Download the script from Github

 git clone git://github.com/obi-a/speedtrain.git

Step 3: Change to the speedtrain directory (the script is called speedtrain)

 cd speedtrain

Step 4. Make the script executable

 chmod +x speedtrain

Step 5. Run the script

 ./speedtrain

This will install Ruby 1.9.2,RubyGems, Rails 3 and Sqlite. It will create a folder in your $HOME directory for your Apps called rails_apps. It will also create a sample Rails App called testapp.

To run the sample Rails app. Type…

 cd $HOME/rails_apps/testapp
 rails server

To view the app, open a browser and type http://localhost:3000/

To create a new Rails app. Type..

 cd $HOME/rails_apps
 rails new myapp

Who should use this script

  • Rubists from MS Windows and OS X getting into Ruby/Rails/Linux
  • Non-Rubists that need to run Rails apps on Ubuntu
  • Newcomers to the Ruby/Linux World
  • Rubists that only need Ruby 1.9.2

Checking Up On Your Linux Server from a Webpage

21 Aug

I was playing with CGI. I wrote a simple cgi web app that allows you to see what is going on with your Linux server from a web page. This is just a simple app for educational purposes. Its not Nagios by any means:)

Linux Commands
Fun linux commands used by the app to get server information.

hostname
This will display the hostname of your system on the terminal

uptime
Displays how long the system has been running and the number of users currently logged in.

w
Lists all the users logged into the system, what programs they are running, when they logged in and how active or idle they have been.

free -m
Displays the amount of free memory on the system.

df -h
Displays information about the hard drive, displays the size, used and available space.

ps aux
ps command displays the processes running on the system. The fun thing about the ps command is that you can format the results and choose which parameters to include in the results. You can also sort the results using –sort. An interesting variation of the ps command is

ps -eo start,pid,user,args --sort user
This will display all the processes running on the system, arranged by Time STARTED, PID , USER of that process and COMMAND they are running/location of the executable all ordered by Process USER. More details about the ps command here.

pstree
Displays a tree diagram of all processes running on the system. It shows both the parent and their child (spawn) processes, so it gives you a good idea of what is going on in the system.

System Files
Some system files contain important information about the server. The information from these files are displayed on the terminal using the cat command.

cat /etc/issue
Displays the System’s Linux Distro and the version number.

cat /proc/version
Displays the systems kernel version and build information.

cat /proc/cpuinfo
Displays the system’s CPU information

Displaying Results of a Shell Script on a Webpage
We do this using CGI. CGI is an interface for executing scripts, receiving and processing requests from clients on a web server. Most popular web servers like Apache and lighthttpd support CGI. CGI scripts can be written in any language. To get the webserver to execute a cgi script simply put that script in the cgi-bin directory.
Debian/Ubuntu has its cgi-bin directory at /usr/lib/cgi-bin and CentOS/Fedora/RedHat has its cgi-bin directory at /var/www/cgi-bin. You must have Apache,lighthttpd or a web server that supports CGI running on the system.

Nixcraft already wrote an excellent tutorial on displaying results from shell scripts on a webpage, read it first to see how to do it. Click here for the tutorial. The app I wrote extends the cgi script in that tutorial. I added menu options and more features to it.

SysInfo: The Server Check Up CGI Web App
The APP consists of 4 CGI scripts.

index.cgi – Displays the basic information about about the system.

cpu-info.cgi -Displays the systems CPU details (vendor,model,speed,core etc).

ps.cgi -Displays the Processes running on the system by TIME STARTED, PROCESS ID, USER,COMMAND.

pstree.cgi -Displays the running processes in a tree diagram showing the parent and their child processes.

All the scripts assume they are running from the directory cgi-bin/sysinfo/. To test the App manually, create a folder in your cgi-bin directory called sysinfo.

For Ubuntu/Debian use:
mkdir /usr/lib/cgi-bin/sysinfo

For CentOS/Fedora:
mkdir /var/www/cgi-bin/sysinfo

Now create the scripts with your favorite text editor and save them in the cgi-bin/sysinfo/ folder. You can copy and paste the source code of all the scripts from here:http://whisperservers.com/sysinfo/. you only need to create index.cgi,cpu-info.cgi,ps.cgi and pstree.cgi.

Next step is to make all the scripts executable:
sudo chmod +x index.cgi cpu-info.cgi ps.cgi pstree.cgi

Now you are done, to view the App, open your web browser and type on the address bar http://your-ip/cgi-bin/sysinfo/index.cgi or http://localhost/cgi-bin/sysinfo/index.cgi

To make the app easy to install and test, I wrote a script that will install it for you, so you dont have to do any of the steps described above, you simply run the installer script and open your web browser to use the app.

Using the installer script to Install the App;
Step 1. Download the installer script with

wget http://whisperservers.com/sysinfo/install-sysinfo

Step 2. Make the installer script executable

chmod +x install-sysinfo

step 3. Run the installer

./install-sysinfo

Step 4. Now test the app, open your web browser and type on the address bar http://your-ip/cgi-bin/sysinfo/index.cgi or http://localhost/cgi-bin/sysinfo/index.cgi

The source code for the installer script, install-sysinfo;

Installing Rails + Apache + Passenger on Ubuntu 10.04 with Speedtrain

08 Aug

[Update 3/7/2011] Check the updated version of the speedtrain script for Ruby 1.9.2 and Rails 3 here: http://obi-akubue.org/?p=922 and https://github.com/obi-a/speedtrain. This version doesn’t install Apache, Passenger yet.

I have written a new version of the Speedtrain script. This version now includes an option to install Rails with Apache and Phusion Passenger ready for production. By default the script will install Ruby, Rubygems, Rails, Sqlite and a Sample app. But by using the advanced option, the script will also install apache and phusion passenger with directions to deploy the Sample app on passenger.

Usage:
Step 1. Download the script

wget http://whisperservers.com/speedtrain

Step 2. Make the script executable

chmod +x speedtrain

Step 3. Option 1
For a basic rails setup for development, which install Rails (Ruby,Rubygems) and Sqlite. simply run the script

./speedtrain

Option 2. For a production type Rails setup, which install Rails (Ruby,Rubygems), Sqlite, Apache and Phusion Passenger run the script with a -p switch.

./speedtrain -p

After the installation the script will create a folder in your $HOME directory called rails_apps. This is the folder where you can create and store your rails apps. The folder is at $HOME/rails_apps. The script will also create a sample Rails app at $HOME/rails_apps/test_app. You can run the sample app by typing

cd $HOME/rails_apps/testapp
ruby script/server

Then open your browser and type http://localhost:3000/

If you used the option to install Apache and Passenger, you will be guided interactively through the Apache + Passenger installation. After the installation, follow the simple steps displayed on the screen to deploy Rails apps on passenger. Very easy steps:)

This script is ready to run on most Ubuntu 10.04 installations. Works great and easy on ubuntu as host OS on a machine. Using virtual box Apache gets some permission issues but should be easy to fix if one digs deeper. It works perfectly on Amazon EC2 Ubuntu 10.04 instances.

To install Rails with Passenger on an EC2 instance with this script you can use this Ubuntu AMI image# ami-2d4aa444 or choose one from here

Using these AMIs the username is literally “ubuntu” as in
ssh -i yourkeyname.pem ubuntu@ec2-123-45-67-89.compute-1.amazonaws.com. I found this in the comments after some digging.

Have fun.

Installing Ruby on Rails on Ubuntu 10.04 with speedtrain

31 Jul

[Update 3/7/2011] Check the updated version of the speedtrain script for Ruby 1.9.2 and Rails 3 here:http://obi-akubue.org/?p=922 and https://github.com/obi-a/speedtrain.

I wrote a small user friendly script that installs Ruby on Rails on Ubuntu 10.04. This script installs Ruby,Rubygems, Rails and sqlite. It also creates a sample Rails App.

Usage:

To install Ruby on Rails on Ubuntu 10.04 with this script, using command line.

Step 1: Download the script.

wget http://whisperservers.com/speedtrain

The script is called speedtrain.

Step 2. Make the script executable

chmod +x speedtrain

Step 3. Run the script

./speedtrain

The script will install Ruby,RubyGems, Rails and sqlite. It will then create a folder in your $HOME directory (~/rails_app/) called rails_apps. This is the folder where you store the rails apps you create. The script will also create a sample Rails App. The sample app is located at ~/rails_app/testapp.

To run the sample Rails app. Type…
cd ~/rails_apps/testapp
ruby script/server

Open the browser and type http://localhost:3000/
