As long as the "domain" remains the same the same cert should work.
Once that changes you will need a new cert.



 I will be creating multiple test sites.  Each with a unique domain such as mytestsite.local and anothertestsite.local, each having it's own virtual host and docroot.

How do I create a unique cert for each domain?



There is a number of questions that are asked during the cert creation.

Country Name (2 letter code) [GB]:
State or Province Name (full name) [Berkshire]:
Locality Name (eg, city) [Newbury]:
Organization Name (eg, company) [My Company Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, your name or your server's hostname) []:
Email Address []:
An optional company name []:

I assume what makes each cert unique is the answer to "Common Name (eg, your name or your server's hostname)".  I enter the domain name not the FQDN or hostname of the server.

Or maybe each cert is unique and by associating it with the domain and adding the excretion to the browser is all that is needed?????

I am rather new to creating self signed certs and the above is an assumption.

Any guidance is much appreciated.

Hi,

I've configured a VM using VirtualBox and it is running CentOS 6.6.

To create the self signed cert I followed 3 steps:

1) mkdir /etc/httpd/ssl

2) cd /etc/httpd/ssl

3) openssl req -x509 -nodes -days 4000 -newkey rsa:2048 -keyout
/etc/httpd/ssl/name-of-my-test-site.key -out
/etc/httpd/ssl/name-of-my-test-site.crt

I've tested the cert and it works.

Now I want to add more test sites to my VM.

I've done some research and am not finding any information about
how to configure the self signed cert(s) for multiple sites.  From
reading the docs it appears that I create one cert for the box and
it will be used by all the sites on my box (test/dev VM).  Is this
true or do I need to create a cert specific for each virtual host? 
If I need to create a cert for each virtual host, how do I do so?

Thank you so much for all your help!!

A mouse trap, placed on top of your alarm clock, will prevent you from
rolling over and going back to sleep after you hit the snooze button.
