A simple Ruby script that runs independent instances of the web server in Linux environment.

Multiple HTTP demo with Ruby

A simple Ruby script that runs independent instances of the web server in Linux environment. Servers are listening on ports 5001 and above.

Setup

To run this on your system make sure you have Ruby language support with ruby -v command. If not, add Ruby to your system with your favorite package manager. In this example I'm using Ubuntu.

$ sudo apt install ruby
# OR
$ sudo snap install ruby --classic

We will also need Git and Curl, so if you don't have them, install them as well.

$ sudo apt install git curl

Cloning a repository

$ git clone https://github.com/loopold/multiple-httpd.git
$ cd multiple-httpd

Launch

Here is exaple for start 5 instances. The parameter in square brackets defines the number of instances that we want to run:

$ rake start_http_servers[5]

You can see the list of available tasks with rake --tasks

Attention to ZSH

I have noticed in ZSH problem with launching script. In ZSH we have to add noglob prefix or create an alias to rake command: noglob rake in .zshrc

Verify

Servers are listening on ports 5001 and above. You can verify it with curl command in terminal.

$ curl http://localhost:500\[1-5\]

Close

At this stage we can end processes with SIGTERM signal for all Ruby instances:

$ killall ruby
