Lets Encrypt Scripts

Public Git URL: https://git.sosdg.org/brielle/lets-encrypt-scripts

By: Brielle Bruns bruns@2mbit.com

These are various scripts to make LetsEncrypt easier to use.

Files

Main Scripts

gen-cert.sh - Main script to make it easy to generate LE certs for domain(s)

gen-unifi-cert.sh - Script to add LE cert to a Unifi controller

Support Files

DSTROOTCAX3.txt - Root CA cert for use with the gen-unifi-cert.sh script (now optional and unneeded as the cert is embedded)

apache-le-alias.conf - Use with apache for LE well-known alias config

apache-le-proxy.conf - Use with apache for LE well-known proxy config

How To Use

gen-cert.sh

  1. Do initial cert generation (if using webroot, see script contents for more methods of authentication):

     gen-cert.sh -e email@address.com -d somedomain.com -d otherdomain.com -r /var/www/letsencrypt-root/

  2. Copy cron/renew-ssl-weekly.sh to /etc/cron.weekly, edit as appropriate

  3. Run:

     chmod 750 /etc/cron.weekly/renew-ssl-weekly.sh

  4. Script will now run weekly and renew the certificate if necessary ( < 30 days remain). Don't forget to add any necessary file copies/symlinks/service restarts as needed once the scripts are updated.

gen-unifi-cert.sh

  1. Do initial cert generation:

     gen-unifi-cert.sh -e email@address.com -d unifi.somedomain.com -d unifi.someotherdomain.com

  2. Put in /etc/cron.weekly/renew-unifi-ssl if everything works okay:

     /path/to/script/gen-unifi-cert.sh -r -d unifi.somedomain.com -d unifi.someotherdomain.com

  3. Script will now run weekly and renew the certificate if necessary ( < 30 days remain) and restart unifi only if cert has been renewed.
