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

apache-2.2slackwarevirtualhost

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 )

ServerRoot "/usr"

This is a CGI app I should mention. I added the apps apache configurations to

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

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.

Windows – Content Encoding Error when trying to use GZip on Apache

The first issue is that you have the element with a directory from the file system...

This is from the Apache manual:

When to use <Location>. Use <Location> to apply directives to content that lives outside the filesystem. For content that lives in the filesystem, use <Directory> and <Files>. An exception is <Location />, which is an easy way to apply a configuration to the entire server.

When I setup mod_deflate on Apache I use this setup:

# --------------------------------------------------------
# Deflate Module Configuration
# --------------------------------------------------------
<IfModule deflate_module>
  # Set the location to webservers root
  <Location />
    # Insert the filters
    SetOutputFilter DEFLATE

    # Netscape 4.x has some problems
    BrowserMatch ^Mozilla/4 gzip-only-text/html
    # Netscape 4.06-4.08 have some more problems
    BrowserMatch ^Mozilla/4.0[678] no-gzip
    # MSIE masquerades as Netscape, but it is fine
    BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

    # Make sure proxies don't deliver the wrong content
    Header append Vary User-Agent env=!dont-vary

    # Make sure to never zip binaries (ie6 and chrome has issues with this.)
    SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary
    SetEnvIfNoCase Request_URI \.(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary
    SetEnvIfNoCase Request_URI \.pdf$ no-gzip dont-vary
  </Location>

    # Enable mod_deflate logging by uncommenting these lines
    #DeflateFilterNote Input instream
    #DeflateFilterNote Output outstream
    #DeflateFilterNote Ratio ratio

    #LogFormat '"%r" %{outstream}n/%{instream}n (%{ratio}n%%)' deflate
    #CustomLog logs/deflate_log deflate

Tomcat – Apache2 – mod_expire and mod_rewrite not working in httpd.conf – serving content from tomcat

Probably the ProxyPass / directive you have in your config routes all requests to the Tomcat backend, bypassing all your mod_rewrite directives. You can try to remove the ProxyPass directive and use RewriteRule with the [P] flag after your other rewrites:

mod_rewrite: P|proxy

For the expire headers the situation is worse — in another similar question a solution was not found.

Option +FollowSymLinks would be needed for using mod_rewrite in .htaccess files; in your case it is not required, because you can put everything in the Apache config. Moving rules from config to .htaccess is pointless and can only make things slower. However, there is an important difference between .htaccess and the Apache config — in .htaccess patterns in RewriteRule are matched against relative filesystem paths (which never start with /), while in the VirtualHost context these patterns are matched against the URL path after the hostname, which always starts with /. Therefore at least one of your rules is incorrect:

RewriteRule ^content/(js|css)/([a-z]+)-([0-9]+)\.(js|css)$ /content/$1/$2.$4

should be

RewriteRule ^/content/(js|css)/([a-z]+)-([0-9]+)\.(js|css)$ /content/$1/$2.$4

(note the additional slash in the beginning).
