How to install a valid cert for apache on ubuntu gutsy from cacert.org

1. Create the server key (in this example RSA 1024 bit):

     openssl genrsa -out host.key 1024

2. Make a certificate out of it (it won’t be signed yet):

     openssl req -new -key host.key -out host.csr

3. Create your CA certificate (will be valid for a year):

     openssl req -new -x509 -days 365 -key host.key -out host.crt

Copy info from host.crt and plug it into website of cacert. It will create text you will put in a .csr file

Create the .csr file in the /etc/apache2/ssl area, in this case I called it my host name m1box.csr.

cp host.key m1box.key

Enable the SSL module

sudo a2enmod ssl

Listen to port 443

echo "Listen 443" | sudo tee -a /etc/apache2/ports.conf

Create and enable the SSL site

sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/ssl

Modify it so it looks something like this

NameVirtualHost *:443
<virtualhost *:443>
        ServerAdmin webmaster@localhost

        SSLEngine On
        SSLCertificateFile /etc/apache2/ssl/m1box.csr

	SSLCertificateKeyFile /etc/apache2/ssl/m1box.key

…and enable it

sudo a2ensite ssl

don’t forget to modify /etc/apache2/sites-available/default

NameVirtualHost *:80 <virtualhost *:80>
