How to create a https virtual host?

Hi, let's say I have a site called abc.net. In "/etc/httpd/conf/httpd.conf", the VirtualHost configuration for the site looks like the following...
<VirtualHost 10.10.11.155:80>
ServerName abc.net
ServerAlias www.abc.net
ServerAlias webmail.abc.net
...
...
...
</VirtualHost>

Open in new window

So, abc.net is working fine so far, but now I want to create a https version of the site...

First, I generated an RSA key...
openssl genrsa -des3 -out privkey.pem 2048

Open in new window

Then I created a self-signed test certificate...
openssl req -new -x509 -key privkey.pem -out cacert.pem -days 1095

Open in new window


In httpd.conf, below "Listen *:80", I added "Listen *:443".
Below the "VirtualHost" block above, I added the following...
<VirtualHost 10.10.11.155:443>
ServerName abc.net
ServerAlias www.abc.net
ServerAlias webmail.abc.net
...
...
...
SSLEngine on
SSLCertificateFile /home/cwpi/tmp/certs/privkey.pem
SSLCertificateKeyFile /home/cwpi/tmp/certs/privkey.pem
SSLCACertificateFile /home/cwpi/tmp/certs/cacert.pem
</VirtualHost>

Open in new window

Then I restarted the httpd service. But I still can't access my site at https://www.abc.net. The "http" one still works fine though.
From my steps above, where did I go wrong and what did I miss out? Thanks!

Hi

Did you open port 443 in the firewall?

I think it's already open... From my PC, I can "telnet www.abc.net 443".

Going to the https site now in IE shows a "Certificate error" icon in the address bar.
Viewing the certificate shows that it's valid from 3 Dec 2012 to 3 Dec 2013.
So I think there is already a certificate, just that it's expired.
There is a file called "localhost.crt" at "/etc/pki/tls/certs" and "localhost.key" at "/etc/pki/tls/private".
There are two lines in "/etc/httpd/conf.d/ssl.conf" that look like the following...
SSLCertificateFile /etc/pki/tls/certs/localhost.crt
SSLCertificateKeyFile /etc/pki/tls/private/localhost.key

Open in new window

So I proceeded to do the following...
 - cd /etc/pki/tls/private
 - openssl genrsa -des3 -out localhost.key 1024
 - cd /etc/pki/tls/certs
 - openssl req -new -key ../private/localhost.key -out localhost.csr
 - openssl x509 -req -days 365 -in localhost.csr -signkey ../private/localhost.key -out localhost.crt
 - service httpd graceful

Output is as follows...
[Tue Feb 04 10:45:38 2014] [warn] module ssl_module is already loaded, skipping
httpd: apr_sockaddr_info_get() failed for UNIX-998A-SG
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[Tue Feb 04 10:45:43 2014] [warn] NameVirtualHost 10.10.10.48:80 has no VirtualHosts
[Tue Feb 04 10:45:43 2014] [warn] NameVirtualHost *:80 has no VirtualHosts

Going to the site now shows a "Page cannot be displayed" error message.

So I had to restore the original .key and .crt files and restart the httpd service again, to get the site to work properly again.

Ok, I found a script called "/etc/pki/tls/certs/make-dummy-cert".
So I went to the folder and executed "./make-dummy-cert dummy.crt".
The dummy.crt file contained both a private key and certificate.
So I copied the private key and certificate and paste it in "/etc/pki/tls/private/localhost.key" and "/etc/pki/tls/certs/localhost.crt".
Then I gracefully restarted httpd.
This time the http version is still ok, and the certificate error displayed is slightly different.
It now shows that the validity of the certificate is from 4 Feb 2014 to 4 Feb 2015.
So I guess the new certificate is correctly loaded.
The error now is...
This CA Root certificate is not trusted. To enable trust, install this certificate in the Trusted Root Certification Authorities store.

Edit: Going to the http version, site loads fine. But going to the https version, I see an empty page.

Update:

I've re-inserted the "<VirtualHost 10.10.11.155:443>" block back into httpd.conf, and added in the following in the block...

SSLEngine on
SSLCertificateFile /etc/pki/tls/certs/localhost.crt
SSLCertificateKeyFile /etc/pki/tls/private/localhost.key

Applied the changes, and the https version of the site is now working!

Another thing, I find it to be quite redundant if every site needs to have 2 "VirtualHost" blocks in httpd.conf if I want the site to be accessible from both port 80 and 443. For example, for http access through port 80...
<VirtualHost 10.10.11.155:443>
ServerName abc.net
ServerAlias www.abc.net
ServerAlias webmail.abc.net
...
...
...
</VirtualHost>

Open in new window

And for https access through port 443...
<VirtualHost 10.10.11.155:443>
ServerName abc.net
ServerAlias www.abc.net
ServerAlias webmail.abc.net
...
...
...
SSLEngine on
SSLCertificateFile /etc/pki/tls/certs/abc.crt
SSLCertificateKeyFile /etc/pki/tls/private/abc.key
</VirtualHost>

Open in new window

Is it possible to set the 443 directive within the same virtual host as the port 80? Thanks.

You can use any # of hosts and ports in a single Virtualhost directive.

<VirtualHost addr[:port] [addr[:port]] ...> ... </VirtualHost>

Example

<VirtualHost *:80 *:443>
  ServerName loop.lk

 ....
SSLEngine on
SSLCertificateFile /etc/apache2/ssl/local.crt

</VirtualHost>
