apache2配置中的ServerName和ServerAlias有什么区别?

问题描述

我正在配置apache2服务器，我想知道ServerName和ServerAlias之间有什么区别.

I am configurating my apache2 server and I wonder whats the difference between ServerName and ServerAlias.

ServerName是否像google.de一样总是不带www的名称而ServerAlias是www.google.de

Is the ServerName always a name without www as like google.deand the ServerAlias is www.google.de

即使是这样，我也听不懂:)对不起.

Even if it's like this, I don't get it :) sorry.

推荐答案

来自文档:

ServerAlias:将请求与名称虚拟主机匹配时使用的主机的备用名称

ServerAlias:Alternate names for a host used when matching requests to name-virtual hosts

大多数人只是使用ServerName设置网站的主要"地址(例如，"mywebsite.com")，并使用ServerAlias添加要绑定到该网站的其他地址(例如，"www.mywebsite" .com').

Most people simply use ServerName to set the 'main' address of the website (eg. 'mywebsite.com') and ServerAlias to add additional addresses the website will be bound to (eg. 'www.mywebsite.com').

但是，两者之间存在细微的差异:

Yet, there are subtle differences between the two:

• ServerName也可以接受端口号，而ServerAlias不能.
• ServerAlias可以接受通配符(例如* .mywebsite.com)，而ServerName则不能.

• ServerName can accept port numbers as well, while ServerAlias cannot.
• ServerAlias can accept wildcards (eg. *.mywebsite.com), while ServerName cannot.
