当我已经有根域的SSL证书时，如何添加在dnsimple上为子域购买的SSL证书？

Question

In Heroku Settings, the SSL is showing for www.example.com but there is no where for me to add an SSL certificate for subdomain.example.com.

In DNSimple instructions it says to install the certificate at the command prompt:

$ heroku certs:add subdomain_example_com.pem subdomain_example_com.key

This results in:

Resolving trust chain... done
 ▸    Potentially Destructive Action
 ▸    This command will change the certificate of endpoint *********-17151 from ⬢ afternoon-********-5203.

$ heroku certs

***********-17151  www.example.com, example.com  2018-01-29

How do I install this SSL certificate for the subdomai without messing with the existing SSL certificate for www.example.com?

您在Heroku上只能拥有一个SSL证书，因此，如果您想要的子域比www多，则需要通配符SSL证书。
