Apache2 on Slackware: VirtualHost config - connection refused on port 8080

  • 772

I am trying to configure virtual hosts on a Slackware server and have run into a glitch.

When I browse to localhost or 127.0.0.1 I get:

Forbidden

You don't have permission to access / on this server.

I need to finish configuring the WebApp at 8080. When I browse to localhost:8080 or 127.0.0.1:8080 I get:

Unable to connect

          Firefox can't establish a connection to the server at 127.0.0.1:8080.

Some context: I need to duplicate the following instructions for Debian/Ubuntu on Slackware and need a hand --- so here's the Debian version:

5. sudo ln -s /etc/koha/koha-httpd.conf /etc/apache2/sites-available/koha
6. sudo a2enmod rewrite deflate
7. sudo a2ensite koha && /etc/init.d/apache2 reload

So far: My httpd.conf ( LoadModule stuff and comments left out )

This is a CGI app I should mention. I added the apps apache configurations to /etc/httpd/extra/httpd-vhosts.conf ( here with comments deleted ):

Have I missed a fundamental basic here? I should mention that the modules deflate, rewrite and perl are installed and in the LoadModule instructions.

Thanks!

UPDATE - with a concern/question

First -- Thank you quanta for your help thus far. I suspected a permissions issue and added this to my httpd.conf directory stanza.

<Directory "/srv/httpd/cgi-bin">
    AllowOverride None
    Options None
    Order allow,deny
    Allow from all
</Directory>

Changed deny from all to "allow from all". So now it works and I thank you again, however, have I just committed major security faux paux?

    Forbidden

    You don't have permission to access / on this server.

    Take a look at Apache error log, it will tell you more details.

    Both. The public side is at 80, the admin/intranet side is at 8080.

    For the testing purpose, add 2 hostnames into the /etc/hosts:

    127.0.0.1 public.example.com
127.0.0.1 private.example.com

    Change the Listen from:

    Listen 127.0.0.1:80

    to

    Listen 80
Listen 8080

    Restart Apache and make sure that Apache is listening on both port with:

    netstat -nlp | grep httpd

    Remove the line NameVirtualHost *:80

    In <VirtualHost *:80>, change ServerName to public.example.com and in <VirtualHost *:8080>, change ServerName to private.example.com.

    Restart Apache, and browse to the http://public.example.com and http://private.example.com:8080 to see what happens.
