Revert the full commit

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.

git revert {commit_id}

Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:

Let's Encrypt

Examples of getting certificates from Let's Encrypt working on Apache, NGINX and Node.js servers.

git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt

AWS ELB with Node.js and WebSockets

This assumes that:

You want to accept incoming connections on port 80.
Your Node.js app is listening on port 3000.
You want to be able to connect to your Node.js instance directly as well as via the load balancer.
