Your first Rails app!
Click the big Sign Up button Enter your email address. (Use the same email address for heroku, git, github, and ssh.)
Heroku will send you an activation email. Open it and click on the activation link. It will take you to the Heroku site. Enter and confirm your password. Hit Save.
Heroku can be a free service, but you will eventually have to add a credit card (I think after 5 apps), although it is still free unless you use add-ons or increase the preformance. The value Heroku provides is worth hundreds of dollars, feel lucky that this exists and all you have to do it provide a number and not actually pay anything.
click the download link, and install.
Type this in the terminal: heroku version
Expected result: 3.0.0 or higher
An SSH key uniquely identifies you (and your computer) when your computer is communicating with other computers. Think of an SSH key as a fancy password
ssh-keygen -C [email protected] -t rsa
Hit enter to accept blank passphrase, then hit enter again
After key generation is complete, you'll have output that looks like this.
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/student/.ssh/id_rsa):
Created directory '/Users/student/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/student/.ssh/id_rsa.
Your public key has been saved in /Users/student/.ssh/id_rsa.pub.
The key fingerprint is:
88:54:ab:77:fe:5c:c3:7s:14:37:28:8c:1d:ef:2a:8d [email protected]
Your brand-new public key is now stored at ~/.ssh/id_rsa.pub
If you look inside ~/.ssh/, you will notice two files with the same name: id_rsa and id_rsa.pub.
id_rsa.pub is your public key and can be shared freely.
id_rsa is your private key and must be kept secret.
If someone else gets your private key and your passphrase, then they can pretend to be you and log on to your Heroku or Github accounts and cause mischief!
