How to configure NGINX with LetsEncrypt using the simp_le client.
this includes the nginx configs, as well as the auto renewal steps. I took a bunch of these steps from this blog, and adapted it to how I like.
simp_le issues three return codes depending on the status of the request.
- 0 if certificate data was created or updated;
- 1 if renewal not necessary;
- 2 in case of errors.
