Https with letsencrypt and nginx
December 15, 2015
Letsencrypt have arrived, and it is a major leap in information security.
We all know we should set up https with valid certificates. Traditionally this has however not been without annoying

Letsencrypt changes this by providing a free certificate authority with an api and good tooling for automation.
This post will show how to install letsencrypt on fedora (22 and 23) and RHEL 7 (including centos 7).
EPEL is extra packages for Enterprise Linux (eg. rhel). They are created by the Fedora project and a reasonably stable.
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
For RHEL and Centos
yum install letsencrypt
dnf install letsencrypt
