[Monil]

When i start Apache after created a virtual host file and enabled it and restart the HTTPD service on web host, the following warning message appears [warn] NameVirtualHost *:80 has no VirtualHosts there is very thing fine with Apache HTTP service so what is this NameVirtualHost *:80 has no VirtualHosts .how to make it work ?
thank you .

this message is error warning message and it have no relation to function of web server so Apache HTTP service looks fine and hence the websites on the server can work. i am not sure but this is may be due to wrong use of NameVirtualHost.

Maybe you're making the modifications to the config file try at best to use IPs or * for the NameVirtualHost and VirtualHost . In some cases, with dedicated IP address only one virtual host is declared, the NameVirtualHost can be dropped. You can use a *, and as such it will be active for every IP on your system.

To fix this problem, look out declaration in /etc/apache2/ports.conf:

grep NameVirtualHost /etc/apache2/ports.conf
#NameVirtualHost *:80

also try this add a ServerName directive, as follows:

<virtualhost *:80>
ServerName hostname
ServerAdmin webmaster@localhost
