Apache Warn NameVirtualHost *:80 Has No VirtualHosts Error When Start阿帕奇警告namevirtualhost * ： 80没有virtualhosts时发生错误开始

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.当启动Apache Web服务器或重新启动的httpd服务， Web主机，下面的警告消息，可能会出现在控制台或错误日志，即使Apache的HTTP服务仍然可以启动和运行的罚款，没有错误。

[warn] NameVirtualHost *:80 has no VirtualHosts [警告] namevirtualhost * ： 80没有virtualhosts

where * can be asterisk itself (*), hostname or IP address.其中*可以本身的星号（ * ） ，主机名或IP地址。

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.幸运的讯息，只是一个警告讯息，并不会影响功能的Web服务器，因此网站上托管的服务器，仍然是可以妥善的服务。 The possible cause for this problem’s symptom is incorrect use of NameVirtualHost.可能的原因对于这个问题的症状是不正确使用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.当服务器，专用或虚拟专用服务器的虚拟主机，只有一个IP地址，网站代管由Apache通过名称为基础的虚拟主机。 In this case, there should be only one NameVirtualHost been defined.在这种情况下，应该只有一个namevirtualhost已确定了。 For example,举例来说，

NameVirtualHost *:80 namevirtualhost * ： 80
<VirtualHost *:80> <virtualhost *:80>
servername host服务器主机
serverPath /public_html/ serverpath / public_html /
DocumentRoot /public_html/ documentroot / public_html /
</VirtualHost> < /虚拟主机>

The name of one or more virtual hosts (websites’ domain name) is defined by “servername” directive.的名称，一个或多个虚拟主机（网站域名）的定义是“服务器”的指令。 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.因此，如果你有一个以上的网站设于一个单一的IP地址，你将有一个namevirtualhost宣言和许多虚拟主机部分配置这些领域。

Beside, try at best to use IPs or * for the NameVirtualHost and <VirtualHost> directives.旁边，尝试在最好地利用IP或*为namevirtualhost和<virtualhost>指示。 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.在有些情况下，该网站被分配到一个专用的IP地址的地方只有一个虚拟主机是宣布， namevirtualhost ，甚至可以下降。
