Activate ssl module

a2enmod ssl

Generate certificates, cf above or in short:

openssl req -config /etc/ssl/openssl.cnf -new -out mydomain.csr
openssl rsa -in privkey.pem -out mydomain.key
openssl x509 -in mydomain.csr -out mydomain.crt -req -signkey mydomain.key -days 3650
openssl x509 -in mydomain.crt -out mydomain.der.crt -outform DER

Install mydomain.crt and mydomain.key in /etc/apache2/ssl/

cp /usr/share/doc/apache2/examples/ssl.conf.gz /etc/apache2/sites-available
gunzip ssl.conf.gz
mv ssl.conf mydomain_ssl
strip it... TODO
SSLCertificateFile /etc/apache2/ssl/mydomain.crt
SSLCertificateKeyFile /etc/apache2/ssl/mydomain.key
<VirtualHost my_ip:443>

/etc/apache2/ports.conf:

Listen <my_ip>:443

ln -s /etc/apache2/sites-available/mydomain_ssl /etc/apache2/sites-enabled

Enable reverse-proxy

a2enmod rewrite                                                                     
a2enmod proxy                                                                       
a2enmod proxy_http

Personally I created a /etc/apache2/proxy-available and proxy-enabled directories with from the :443 VirtualHost an inclusion rule:

Include /etc/apache2/proxy-enabled/

First file to create is to initialize rewrite and proxy, e.g. /etc/apache2/proxy-enabled/000init -> /etc/apache2/proxy-available/init

RewriteEngine On
RewriteLog /var/log/apache2/rewrite.log
<Proxy *>
 Order deny,allow
 Allow from all
</Proxy>

Example of rules:

# Rules for https://foo.yobi.be

# Here this was a service that had to be called with the index.htm explicitely so we redirect the browser
RewriteCond %{HTTP_HOST} ^foo.yobi.be:?[0-9]*$
RewriteCond %{REQUEST_URI} ^/?$
RewriteRule ^/? /index.htm [R]
# Then the real rule:
RewriteCond %{HTTP_HOST} ^foo.yobi.be:?[0-9]*$
RewriteRule ^/(.*) http://twilight.zone/$1 [P]
ProxyPassReverse / http://twilight.zone/

# Rules for https://www.yobi.be/foo

# Here this was a service that had to be called with the index.htm explicitely so we redirect the browser
RewriteCond %{REQUEST_URI} ^/foo/?$
RewriteRule ^/foo/? /foo/index.htm [R]
# Then the real rule:
RewriteCond %{REQUEST_URI} ^/foo.*
RewriteRule ^/foo/(.*) http://twilight.zone/$1 [P]
ProxyPassReverse / http://twilight.zone/

To understand RewriteCond, see the mod_rewrite documentation

Older notes

Activate a module

Find the module name, try

ls /usr/lib/apache/1.3/*.info|sed 's/^[^_]*_\(.*\)\.info/\1/'

apache-modconf apache enable module name

E.g. apache-modconf apache enable libproxy

Setup proxy HTTP1.1 with Apache 2

libapache2-mod-proxy-html
