Let's Encrypt Wildcard SSL Certificate support on RHEL 7 OS for installation

Is the wildcard SSL support RHEL 7 and above.

Thank You!

Wildcards are absolutely supported under RHEL 7. Like all wildcard certificates, they require the use of DNS validation. I’d recommend using acme.sh, both since it isn’t a tangled mess of dependencies the way certbot is, and because it has much better support for DNS providers’ APIs.

Thank You! for prompt response and Info

Please share me the Wildcard SSL certificate installation document for RHEL7

Installation is going to be entirely up to you. “RHEL7”, as such, doesn’t use certificates at all; rather, many services that you can choose to run on it (e.g., Apache, Nginx, Postfix, Asterisk, MariaDB, etc.) do. The instructions for installing a certificate in any of those services will be different–each will have its own configuration options, each will expect its certs to be in a different location, and each will require a different command or sequence of commands to tell the service to read a new cert.

To get the cert in the first place, consult the docs for acme.sh at the link I gave you above. You’ll need to use DNS validation; the acme.sh documentation covers how to do that in some detail.

Hi @nithinknk

there is no such document.

Start with

then read something about challenge types:

Next step: Select a client and use it. Then it’s client specific.

I have successfully installed Wildcard SSL on my RHEL.

Could you please help me…How to check the Wildcard SSL auto renewal is enabled or not and where i need to check.

Thank You!

How did you install it?

I followed below link

You did not get a wildcard cert following those instructions.

By using following command i have created wildcard SSL

'./certbot-auto certonly --manual --preferred-challenges dns --server https://acme-v02.api.letsencrypt.org/directory --manual-public-ip-logging-ok -d '*.domainname.inf -d domainname.inf"

So you have to do that every 60 - 85 days. Read
