On my Raspberry Pi 3+ I followed the instructions to install and configure apache, and now I can view:

  1. Default apache configuration on localhost, and
  2. GCI webpage on gci.example.com

Configuration Files

gci.conf

pi@raspberrypi:~ $ cat /etc/apache2/sites-available/gci.conf
<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        ServerName gci.example.com

        ServerAdmin  [email protected]
        ServerAlias  www.gci.example.com
        DocumentRoot /var/www/gci/public_html/

        <Directory /var/www/gci/public_html/>
                Options Indexes FollowSymLinks
                AllowOverride all
                Require all granted
        </Directory>

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

hosts

pi@raspberrypi:~ $ cat /etc/hosts
127.0.0.1       localhost
::1             localhost ip6-localhost ip6-loopback
ff02::1         ip6-allnodes
ff02::2         ip6-allrouters

127.0.1.1       raspberrypi
127.0.0.1       www.gci.example.com

Access both localhost and gci.example.com

I have connected to my Pi using SSH using PuTTY, and I have added the tunneling as below: enter image description here

Now, when I go to localhost I can see the default apache page which is configured, but I am not able to find the gci webpage.

I've tried to use a different port, but it was not working. I am new to apache, so might have done something wrong?

I want to access multiple websites configured under /var/www/ of my Pi from my Windows machine using PuTTY, or other tools (if required).

These links link-1, link-2 suggested using DNS settings, but I don't understand how to do that.

  • Why are you tunneling through port 80. Why not SSH to default port 22? And why SSH to localhost?

  • Using SSH on Port 22, but tunneling apache port 80 (I thought that was the default one).

  • Just to be clear... do you want to access the directories and files under /var/www/ or do you want to tunnel the HTTP requests from web-browser on one machine to a web-server on another machine via SSH?

  • Then do not use localhost in the tunnel destination... use the IP of the other machine instead.
