不幸的是，我似乎无法在线获取一个简单的 Apache VHost。我以前只有一个绑定到所有：的 VHost <VirtualHost *:80>，但出于安全考虑，这不再合适。我需要一个 VHost 用于本地主机请求（即我的开发服务器），另一个用于通过我的域名传入的请求。
这是我的新 VHost：
NameVirtualHost domain1.com
<VirtualHost domain1.com:80>
DocumentRoot /var/www
ServerName domain1.com
</VirtualHost>
<VirtualHost domain2.com:80>
DocumentRoot /var/www
ServerName domain2.com
</VirtualHost>
重新启动服务器后，我在日志中看到以下错误：
[Wed Feb 16 11:26:36 2011] [error] [client ####.###.###.###] File does not exist: /htdocs
[Wed Feb 16 11:26:36 2011] [error] [client ####.###.###.###] File does not exist: /htdocs
我究竟做错了什么？

根据下面给出的答案，我修改了我的配置。以下是我的配置文件：
/etc/apache2/ports.conf：
Listen 80
<IfModule mod_ssl.c>
# If you add NameVirtualHost *:443 here, you will also have to change
# the VirtualHost statement in /etc/apache2/sites-available/default-ssl
# to <VirtualHost *:443>
# Server Name Indication for SSL named virtual hosts is currently not
# supported by MSIE on Windows XP.
Listen 443
</IfModule>
<IfModule mod_gnutls.c>
Listen 443
</IfModule>
以下是我实际定义的站点：

只是为了好玩，我的主要文件是：
/etc/apache2/apache2.conf：
#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.2/ for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# The configuration directives are grouped into three basic sections:
# 1. Directives that control the operation of the Apache server process as a
# whole (the 'global environment').
# 2. Directives that define the parameters of the 'main' or 'default' server,
# which responds to requests that aren't handled by a virtual host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow Web requests to be sent to
# different IP addresses or hostnames and have them handled by the
# same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log"
# with ServerRoot set to "" will be interpreted by the
# server as "//var/log/apache2/foo.log".
#
### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs-2.1/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.

我还需要做什么来修复它？我应该告诉 apache 在 127.0.0.1:80 上监听吗，还是它还没有在那里监听？
答案1
如上所述，您应该稍微改变一下配置才能NameVirtualHost正确使用该指令。
此外，为了使基于名称的虚拟主机正常工作，您需要在默认配置中定义一个 ServerName。
编辑文件以匹配以下内容：
/etc/apache2/ports.conf
Listen 80
NameVirtualHost THE_PUBLIC_OR_LAN_IP_OF_THE_SERVER:80
NameVirtualHost 127.0.0.1:80
<IfModule mod_ssl.c>
# If you add NameVirtualHost *:443 here, you will also have to change
# the VirtualHost statement in /etc/apache2/sites-available/default-ssl
# to <VirtualHost *:443>
# Server Name Indication for SSL named virtual hosts is currently not
# supported by MSIE on Windows XP.
Listen 443 </IfModule>
<IfModule mod_gnutls.c>
Listen 443 </IfModule>
/etc/apache2/sites-enabled/001-rfkrocktk.dyndns.org：
<VirtualHost THE_PUBLIC_OR_LAN_IP_OF_THE_SERVER:80>
DocumentRoot /var/www
ServerName rfkrocktk.dyndns.org
</VirtualHost>
答案2
首先，您需要检查监听器的配置方式（Listen配置指令）。
NameVirtualHost后面应该跟一个类似这样的条目：ip:port或者*:port。在您的情况下：
Listen 127.0.0.1:80
Listen 192.168.10.30:80
NameVirtualHost 127.0.0.1:80
NameVirtualHost 192.168.10.30:80 # Your "external" IP.
<VirtualHost 127.0.0.1:80>
...
</VirtualHost>
<VirtualHost 192.168.10.30:80> # Same signature as NameVirtualHost
...
</VirtualHost>
