This article describes how to secure your webpage running on apache2 with https. You create demo-certificates yourself for this. Find out your distribution, then proceed accordingly:

SUSE Linux

This article assumes you know about SSL, https and certificates.

1. set up your Certification authority and create dummy-certificates

/usr/bin/gensslcert

2. get your SSL Configuration from the given template

cd /etc/apache2/vhosts.d
cp vhost-ssl.template vhost-ssl.conf

3. change your SSL Configuration

have apache2 start per default with SSL. To do this, edit /etc/sysconfig/apache2: replace

APACHE_SERVER_FLAGS=""

with

APACHE_SERVER_FLAGS="SSL"

4. restart apache2

/etc/init.d/apache2 restart

5. make sure you have content to show

echo "this is a test" >> /srv/www/htdocs/index.html

6. test your configuration

wget --no-check-certificate --no-proxy https://localhost

Ubuntu Linux

Follow https://help.ubuntu.com/8.04/serverguide/C/httpd.html. If you use name-based virtual hosts, your apache configuration will look like this afterwards:

<VirtualHost *:443>
ServerName foo.org
DocumentRoot /var/www/foo

SSLEngine on
SSLOptions +StrictRequire
SSLCertificateFile /etc/ssl/certs/server.crt
SSLCertificateKeyFile /etc/ssl/private/server.key
</VirtualHost>
