Enabling SSL for Apache2 on Ubuntu

Edit /etc/apache2/apache2.conf – add:

LoadModule      ssl_module /usr/lib/apache2/modules/mod_ssl.so

Generate SSL certificates:

https://help.ubuntu.com/8.04/serverguide/C/certificates-and-security.html

Add SSL config and 443 port to a new Virtual Host in apache2.conf – for example:

<VirtualHost *:443>
ServerAdmin your_admin@email.com
DocumentRoot /var/www/your_doc_root
SSLEngine on
SSLOptions +StrictRequire
SSLCertificateFile path/to/server.crt
SSLCertificateKeyFile path/to/server.key
ServerName your.server.name
DirectoryIndex index.php
</VirtualHost>

Add a listen port on 443 to /etc/apache2/ports.conf:

NameVirtualHost *:443
