Answer 1

Run the following line on terminal (specify your domain and sub domain name correctly)

sudo nano /etc/apache2/sites-available/subdomain.domain.com.conf 

Paste the following code and change as your requirement

<VirtualHost *:80>
        ServerAdmin admin@domain.com
        ServerName subdomain.domain.com
        ServerAlias subdomain.domain.com
        ProxyRequests Off

        #ProxyPass / http://localhost:8080/
        <Location />
                ProxyPreserveHost On
                ProxyPass http://domain.com:8080/
                ProxyPassReverse http://domain.com:8080/
        </Location>
     # Uncomment the line below if your site uses SSL.
     #SSLProxyEngine On
</VirtualHost>

Run the following lines on terminal (specify your domain and sub domain name correctly)

sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2enmod subdomain.domain.com.conf
sudo service apache2 restart

Answer 2

I use proxy for this type of things.

In my example, I have apache 1.3 running on port 80, but I needed svn repository to run on apache 2.2, and I didn't want to type :82 on the end of the domain every time. So I made proxy redirection on apache 1.3 (port 80):

<VirtualHost *:80>
  ServerName svn.mydomain.com
  ServerAlias svn
  ServerAdmin my@email.com

  <IfModule mod_proxy.c>
    ProxyPass / http://svn:82/
  </IfModule>
</VirtualHost>

Answer 3

A more complete answer to this would be to do something like this which allow you to setup a proxy gateway which is what is loosly described above.

ServerName localhost

<Proxy *>
    Order deny,allow
    Allow from localhost
</Proxy>

ProxyRequests           Off
ProxyPreserveHost       On      

ProxyPass               /       http://localhost:10081/
ProxyPassReverse        /       http://localhost:10081/
ProxyPassReverseCookiePath /    http://localhost:10081/

Answer 4

Off the top of my hat:

Listen 82
Listen 83
NameVirtualHost 1.2.3.4 # Use your server's IP here

<VirtualHost www.myexample.com:82>
# Configure www.myexample.com here
</VirtualHost>

<VirtualHost blog.myexample.com:83>
# Configure blog.myexample.com here
</VirtualHost>

I will assume that you have your own reason for wanting the two sites (www and blog) to run on different ports - and in different processes. If this is not what you intended, e.g. you did not want to have two distinct processes, then having different ports may not be what you intended either: use VirtualHost instead, to co-host the two domains within the same apache+php instance on port 80. Otherwise, read on.

Assuming that you have your two apache+php processes listening on localhost:82 and localhost:83 respectively, bring up a third, apache-only process to act as a reverse proxy. Have the reverse proxy apache instance listen for requests coming on port 80 from the internet, with two virtual host definitions. The first virtual host definition, www, would forward requests to localhost:82, whereas the second virtual host definition, blog, would forward requests to locahost:83, e.g.:

NameVirtualHost *:80

# www
<VirtualHost *:80>
  ServerName www.myexample.com
  ProxyPass               /       http://localhost:82/
  ProxyPassReverse        /       http://localhost:82/
</VirtualHost>

# blog
<VirtualHost *:80>
  ServerName blog.myexample.com
  ProxyPass               /       http://localhost:83/
  ProxyPassReverse        /       http://localhost:83/
</VirtualHost>
