How to change the apache httpd port for serving files

wish helps you The difference is mostly historical at this point, but still enforced by Linux and most Unix implementations that I can think of. Unix/Linux considers any port number < 1024 to be "privileged" and requires root privs to bind to them. Any user should be able to bind to ports higher than 1024. If your software package is of a certain vintage it expects to be started as root, bound to a port, and optionally it will then change effective UID to a non-privileged user. Apache HTTPD falls into this category. Software packages created later on (ie Apache Tomcat) typically went the route of doing everything with a non-privileged user and binding to a higher port number by default.
Some firewall admins can, I'm sure, go into detail about how port < 1024 will sometimes get special treatment in firewall configurations in some cases.

will be helpful for those in need I am trying to integrate wordpress into my site which is running on Nodejs server with Apache Httpd port forwarding enabled to forward all the request from 80 port to Nodejs port 9000. I have installed wordpress into Apache httpd /www/blog folder. , This worked for me. Might be of some help for others.

    <VirtualHost *:80>
         RewriteEngine on
         RewriteCond %{HTTP_HOST} ^blog\.example\.com
         RewriteRule ^(.*)$ http://www\.example\.com/blog/$1 [L]

         ProxyPreserveHost On
         ProxyPass /blog !
         ProxyPass / http://localhost:9000/
         ProxyPassReverse / http://localhost:9000/
         ServerName example.com
    </VirtualHost>

I think the issue was by ths following , Ended up just using nginx. Was much easier to setup and get functioning as a reverse proxy.

To fix the issue you can do I would like to have my Apache httpd launch as non-route user (httpd) and still listen on port 80/443. This server will be running on a Linux host. , You can use iptables for port redirecting:

# iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
