Apache Warn NameVirtualHost *:80 Has No VirtualHosts Error When Start

When start Apache web server or restart the HTTPD service on web host, the following warning message may appears on console or error log, even though Apache HTTP service can still startup and running fine without error.

[warn] NameVirtualHost *:80 has no VirtualHosts

where * can be asterisk itself (*), hostname or IP address.

Luckily the message is just a warning message and does not affect the functionality of web server, and hence the websites hosted on the server can still be served properly. The possible cause for this problem’s symptom is incorrect use of NameVirtualHost.

When the server, dedicated or virtual private server web host, has only one IP address, websites are hosted by Apache via name based virtual hosting. In this case, there should be only one NameVirtualHost been defined. For example,

NameVirtualHost *:80
<VirtualHost *:80>
servername host
serverPath /public_html/
DocumentRoot /public_html/
</VirtualHost>

The name of one or more virtual hosts (websites’ domain name) is defined by “servername” directive. So if you have more than one websites hosted on a single IP address, you will have one NameVirtualHost declaration and many VirtualHost sections to configure those domains.

Beside, try at best to use IPs or * for the NameVirtualHost and <VirtualHost> directives. In some cases, where the website is assigned a dedicated IP address where only one virtual host is declared, the NameVirtualHost can even be dropped.

For more example on how VirtualHost supposed to be setup, visit Apache 2.2 documentation or Apache 1.3 documentation (more common version of Apache used currently as most control panel such as cPanel comes with this, although it’s going to be upgraded in cPanel 11).

    debian lenny – just make sure there is ONLY one instance of
    NameVirtualHost *:80

    and you have receivers for it (ie virtual host entries)

    the definitive place to put NameVirtualHost is in ports.conf

    the message appear because ports.conf not configure.

    If you configure VirtualHost with ip ex.

    Then you must configure at ports.conf with same setting.
    ports.conf
    NameVirtualHost xxx.xxx.xxx.xxx:80
    Listen 80

    I also have same problem. But after I change this setting, that message dissapear.

    Good lUck

    Thanks.

    It was a great help. You would believe how many different opinions there are on which is the right syntax for VirtualHost in Apache.

    Thanks again.

    This warning will also be emitted if there are multiple NameVirtualHost entries.

    In the basic install of Apache 2 on Debian 5 (Lenny) I see the NameVirtualHost in:

    /etc/apache2/sites-enabled/000-default

    and

    /etc/apache2/ports.conf

    So at least this out-of-the-box install will emit this warning every time ‘/etc/init.d/apache2 reload’ is called to check the configuration files.

    If the warning bothers you, just comment out the entry in ports.conf and don’t add new ones; say, from an example site template pasted into a new configuration file.
