Apache2

Enabling/Disabling Mods

• sudo a2enmod mod
• sudo a2dismod mod

SSL

• a2enmod ssl (this just does: ln -s /etc/apache2/mods-available/ssl* /etc/apache2/mods-enabled)
• a2enmod rewrite
• a2enmod suexec
• a2enmod include
• Edit ports.conf and add Listen 443
• Edit sites-available/default and change the lines to look as follows:

NameVirtualHost *:80
<VirtualHost *:80>
...

• Copy sites-available/default to sites-available/ssl and change the above lines to look like:

NameVirtualHost *:443
<VirtualHost *:443>
        SSLEngine On

        #   Server Certificate:
        #   Point SSLCertificateFile at a PEM encoded certificate.  If
        #   the certificate is encrypted, then you will be prompted for a
        #   pass phrase.  Note that a kill -HUP will prompt again.  Keep
        #   in mind that if you have both an RSA and a DSA certificate you
        #   can configure both in parallel (to also allow the use of DSA
        #   ciphers, etc.)
        SSLCertificateFile /etc/apache2/ssl/bretts_org.crt

        #   Server Private Key:
        #   If the key is not combined with the certificate, use this
        #   directive to point at the key file.  Keep in mind that if
        #   you've both a RSA and a DSA private key you can configure
        #   both in parallel (to also allow the use of DSA ciphers, etc.)
        SSLCertificateKeyFile /etc/apache2/ssl/server.pem
...

• ln -s /etc/apache2/sites-available/ssl /etc/apache2/sites-enabled/001-ssl

• /etc/init.d/apache2 force-reload

Problems

Empty /var/log/apache2/rewrite.log

Ensure that these config entries appear once (and only once) within the VirtualHost you wish to debug:

RewriteEngine On
RewriteLog /var/log/apache2/rewrite.log
# Possible values 0 (no rewrite logging) -> 9 (loads of rewrite logging)
RewriteLogLevel 9
