In case you're interested in the history and to answer your prior questions: yes, I started two unique instances with Bitnami hosting and all your tutorials and tools described therein work as advertised. Only issue was my impatience, waiting for things to propagate
Maybe I'd save you time if you showed me the way to look up the Apache command structure. For instance, the Let's Encrypt instructions show how to renew for a single domain only.
This is still under the original topic of upgrading an obsolete stack, by launching new instances
I looked up Let's Encrypt certificate renewal and I have two questions:
All your documentation shows that the Let's Encrypt certificate lasts for 90 days, but my certificate has somehow lasted longer than that. I thought that mine had a 1 year life. In any case, that seems to have happened because I am only just now seeing the expiration notice. Your tutorial shows how to set up auto-renewal, which I can do later, but is there a way to set up the certificate for a year instead of 90 days (which to me is ridiculous) ?
What is the command syntax to set up 2 to 4 domains instead of just one ? Repeat the command for each domain or add multiple domains separated by commas ? (or what ??)
i.e. your Community response here, edited for entering 2 to 4 domain renewals at once:
Step 5: Renew The Let’s Encrypt Certificate
Let’s Encrypt certificates are only valid for 90 days. To renew the certificate before it expires, run the following commands from the server console as the bitnami user. Remember to replace the DOMAIN placeholder with your actual domain name, and the EMAIL-ADDRESS placeholder with your email address.
sudo /opt/bitnami/ctlscript.sh stop
sudo /opt/bitnami/letsencrypt/lego --tls --email="EMAIL-ADDRESS" --domains="DOMAIN" --path="/opt/bitnami/letsencrypt" renew --days 90
sudo /opt/bitnami/ctlscript.sh start
