Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
The operating system my web server runs on is (include version):
Red Hat Enterprise Linux v7.x.x
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don't know):
yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):
whm
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): NA
We have a dedicated server. I have several accounts on the box, each domain have their own cert, but I have not installed a cert for the whole server. We just use the IP to use WHM.
Also icecast 2.4.4 is installed with no cert. Every account(domain) use the icecast service to stream audio.
So I have several questions:
A. How to get lets encrypt cert?
B. Do I need a cert for an IP due icecast is running for the whole server or do I need to set a domain for the whole server?
C. How to install it?
D. How can I reconfig my actual icecast installation if the domains hosted on the server have their own?
E. Can I automate the cert installation to minimize downtimes?
