Configure httpd to listen multiple ports

By default, httpd in Red Hat Enterprise Linux 5 listens on http port 80.
But you can configure it to listen to other ports too.

Solution :

In the configuration file /etc/httpd/conf/httpd.conf, the “Listen” directive tells the server to accept incoming requests on the specified port. Multiple “Listen” directives may be used to specify a number of ports to listen to.

Modify the configuration file /etc/httpd/conf/httpd.conf to add multiple “Listen” directives.
=======================
# Vi etc/httpd/conf/httpd.conf

Example:
Listen 80
Listen 88
Listen 98
========================
Port numbers 80, 88 and 98, in this example, are the ports that httpd would listen to. To make this change effective, restart the httpd service:

# service httpd restart

ou can verify that httpd is listening on all three ports with the command netstat:
========================
# netstat -anp | grep httpd
tcp 0 0 :::80 :::* LISTEN 5278/httpd
tcp 0 0 :::88 :::* LISTEN 5278/httpd
tcp 0 0 :::98 :::* LISTEN 5278/httpd
========================
If your output is similar to the above, the httpd web server is configured to listen on the specified ports. If your browser can not connect to these ports, check the firewall settings on the server or intermediate servers between the client and the httpd server.
