Apache2 SSL

This guide will help you setup SSL with apache2. For an introduction to OpenSSL see: https://help.ubuntu.com/community/OpenSSL The following bugs are related to this documentation:

ubuntu	https://launchpad.net/ubuntu/+source/apache2/+bug/77675
debian	http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=398520

Generate the certificate

Since Ubuntu 7.04, certificate creation has been changed: https://bugs.launchpad.net/debian/+source/apache2/+bug/77675/comments/25 Old fashioned way: Create a certificate which are valid for a year.

sudo apache2-ssl-certificate -days 365

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/apache.pem

        DocumentRoot /var/www/
        <directory />
                Options FollowSymLinks
                AllowOverride None
        </directory>

        <directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
                # This directive allows us to have apache2's default start page
                # in /apache2-default/, but still have / go to the right place
                # Commented out for Ubuntu
                #RedirectMatch ^/$ /apache2-default/
        </directory>

        ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
        <directory "/usr/lib/cgi-bin">
                AllowOverride None
                Options ExecCGI -MultiViews +SymLinksIfOwnerMatch
                Order allow,deny
                Allow from all
        </directory>

        ErrorLog /var/log/apache2/error.log

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn

        CustomLog /var/log/apache2/access.log combined
        ServerSignature On

    Alias /doc/ "/usr/share/doc/"
    <directory "/usr/share/doc/">
        Options Indexes MultiViews FollowSymLinks
        AllowOverride None
        Order deny,allow
        Deny from all
        Allow from 127.0.0.0/255.0.0.0 ::1/128
    </directory>

</virtualhost>

...and enable it

sudo a2ensite ssl

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

NameVirtualHost *:80
<virtualhost *:80>

Mod rewrite

It's often desirable to force users to access things like webmail via https. This can be accomplished with mod_rewrite. First you'll have to enable the module

sudo a2enmod rewrite

Then add the following to /etc/apache2/sites-available/default

RewriteEngine   on
RewriteCond     %{SERVER_PORT} ^80$
RewriteRule     ^/webmail(.*)$ https://%{SERVER_NAME}/webmail$1 [L,R]
RewriteLog      "/var/log/apache2/rewrite.log"
RewriteLogLevel 2

Create directory for pidfile; it may be missing

sudo mkdir -p /var/run/apache2
sudo chown -R www-data /var/run/apache2

Don't forget to restart apache

sudo /etc/init.d/apache2 force-reload
