Certbot Not Renewing

Posted by Dr. Burton on March 17, 2018 in Cloud Computing, Technology, WordPress |

First, this post is more for me as a reminder should I have this problem again. But, if it helps you resolve your problem, yea!

Problem (tl;dr version): Certbot didn’t update the ssl certificates on one of my servers, resulting in ugly messages about the websites not being safe.
Long Version: I’m hosting my own sites on Amazon EC2 servers running AMI flavor of Linux. About a year ago I upgraded from standard webpages to ssl to make Google and other search engines happy. Everything was going fine until recently when the site didn’t renew the certificates for SSL from Let’s Encrypt.
While I had followed the Amazon tutorial exactly (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/SSL-on-an-instance.html#letsencrypt) Certbot wasn’t running any longer. After troubleshooting, I found that it was a common problem with the latest versions of certbot. There were a lot of solutions provided by various people, none worked correctly. What did work is:
Solution:
On the github website (https://github.com/certbot/certbot/issues/1680#issuecomment-358728515) I found a solution that worked:
sudo rm -rf /opt/eff.org/*
sudo pip install -U certbot
sudo certbot renew –-debug

I did have to make one change:
sudo ./certbot-auto renew –-debug

Now the solutions is saved should I (or anyone else) need it!
–debug

Getting Started with Deep Learning

Posted by Dr. Burton on May 15, 2017 in Cloud Computing, Deep Learning, Lua |

Why Deep Learning? Several months ago one of my former students, Dr. Julia S. Slige, began posting a series of tutorials on using R for data mining.  Julia even has a book on the topic published by O’Reilly.  Her posts and subsequent research got me to thinking about Deep Learning, a key part of my […]
