Hello everybody !
I’m new to Ghost (i find it’s a very good CMS) and Linux. He’s hosted at example.com, and i wanna install a Matomo instance at stats.example.com and use the https certificate of Ghost (i don’t know if it’s a good thing in terms of security, tell me). How to do this ? Is it possible ?
Thanks for the help !
Hey @geekcat 
The SSL certificate is not generated by Ghost, rather it’s generated with acme.sh. Ghost just asks acme.sh to create the certificate.
The certificate that’s created by Ghost will only be valid for example.com, so you will have to generate a new certificate for stats.example.com. The installation is located in /etc/letsencrypt
thanks a lot ! didn’t know about that, pretty new about Nginx 
No problem! Just to be clear, acme.sh is a LetsEncrypt client, which integrates with nginx, but is not specific to nginx
