These Instructions are for an ubuntu installation with nginx as the server. This method enables a user to get (free) certificates from an opensource provider and requires the website name to be publicly accessible. These instructions may not be applicable in other environments. Follow all applicable certificate policies when installing. |
Before obtaining the certificates ensure that there are two DNS A record for the website name (i.e. demonodepublicdns).

Automatic certificate renewal uses a cronjob to run the update command twice a day.
1. Ensure the following command returns successfully. It will not make any changes. It will be used in the cronjob to update the certificate if it is in need of renewal.

2. Create a bash script to run when a certificate is updated, updating the certificates recorded in the OpenHIM system.
In Progress |
3. Create a bash script which will be run by a cronjob.
#!/bin/bash ## navigate to directory with ./certbot-auto cd /path/to/certbot-auto ## check if the certificate is expiring soon and renew it if needed sudo ./certbot-auto --config /etc/letsencrypt/configs/ls.datim4u.org.conf certonly --renew-hook "/etc/certbot_renewal/update_OpenHIM.sh" -n # -n ensures a noninteractive session # --renew-hook command only fires if a certificate is renewed exit 0 |
4. Create a cronjob to run twice a day, once at 1:00 AM and once at 1:00 PM.
