Hi All, Welcome to series 2, here are explaining about the ruby and Postgres installation to our GCP Server. If you know about that in linux 16.04 version, you can skip this tutorial. this is entirely based on the ubuntu 16.04 LTS machine and not much . I read the digital ocean, GoRails etc to publish this article and use the tehniques explained by them also.

Install Ruby

Install RVM

connect gpg keys

   sudo apt-get install gnupg2 -y
  gpg2 --keyserver hkp://keys.gnupg.net --recv-keys D39DC0E3

Install RVM

Now, the below command installs the latest version of the rvm and does all the depandancies.

cat rvm.sh | bash -s stable

Now, install the lates version of Ruby, using the below command

RVM use

Installing RVM to /home/username/.rvm/

Adding rvm PATH line to /home/username/.profile /home/username/.mkshrc /homeusername/.bashrc /home/username/.zshrc.

Adding rvm loading line to /home/username/.profile /home/username/.bash_profile /home/username/.zlogin.

Installation of RVM in /home/username/.rvm/ is almost complete:

  • To start using RVM you need to run source /home/username/.rvm/scripts/rvm in all your open shell windows, in rare cases you need to reopen all shell windows.
