Create Self-Signed Root Level Certificate on Ubuntu

  • 772

I have found tutorials in the past for creating self-signed certificates. Now for my personal website (on a virtual server), I want to use a self-signed SSL certificate for logging into my WordPress admin panel. The problem is that I am running multisite; so each site has a different hostname (domain.com, site2.domain.com, site3.domain.com) for the admin panel. Can I create a self-signed certificate that can protect all of the subdomains as well as the root? How do I do that?

Yes, Apache and OpenSSL. The instructions I found are at: https://help.ubuntu.com/10.04/serverguide/C/certificates-and-security.html

ubuntu certificate ssl-certificate

    You should be able to replace domain.com with *.domain.com when generating the CSR.

    Details for using openssl with apache found here

    After you run openssl req -new -key server.key -out server.csr. It will prompt you for a "Common Name" use *.domain.com (where domain.com is your domain name).

    More details may be required like are you using apache? And are you using openssl to generate the cert?
