Jekyll is one of the popular static site generators. To work with Jekyll, you need to have all the required dependencies.

$ sudo apt-get update
$ sudo apt-get install ruby-full build-essential zlib1g-dev

Setup gems installation directory for your user account to avoid installing Ruby Gems as the root user. You will found this informed on Jekyll's website. So add environment variables to ~/.bashrc file to configure installation path.

$ echo '# Install Ruby Gems to ~/gems' >> ~/.bashrc
$ echo 'export GEM_HOME="$HOME/gems"' >> ~/.bashrc
$ echo 'export PATH="$HOME/gems/bin:$PATH"' >> ~/.bashrc
$ source ~/.bashrc

Now install Jekyll by running this

$ gem install jekyll bundler

To create your own blog and test it, run the following

$ jekyll new myblog
$ cd myblog
$ bundle exec jekyll serve

Your site will be running on http://localhost:4000.

Congratulations you've successfully run your own site.
