# This is the main Apache HTTP server configuration file. It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.2> for detailed information.
# In particular, see
# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>
# for a discussion of each configuration directive.
#
# 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.
#
# 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 "log/foo_log"
# with ServerRoot set to "/usr" will be interpreted by the
# server as "/usr/log/foo_log".
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path. If you point
# ServerRoot at a non-local disk, be sure to point the LockFile directive
# at a local disk. If you wish to share the same ServerRoot for multiple
# httpd daemons, you will need to change at least LockFile and PidFile.

# Listen: Allows you to bind Apache to specific IP addresses and/or

#
# Please see the documentation at
# <URL:http://httpd.apache.org/docs/2.2/vhosts/>

答案1
如果出现 404，则表示请求已通过名称解析并到达 apache。因此，您需要查看文档根目录并查看是否有 index.php。查看 apache 的 error.log 可能会为您提供更多提示。
答案2
首先要检查的是您的配置是否包含该文件：
/private/etc/apache2/extra/httpd-vhosts.conf
但你在回答中提到了这一点：
/etc/apache2/extra/httpd-vhosts.conf
确保两者通过目录的符号链接是同义词，或者配置文件本身是符号链接。不包含该文件不仅会排除您的 vhost 配置，还会排除 NameVirtualHost 指令本身。
此外，连接最终会到达哪里。您说您遇到了 404，那么它出现在哪个 apache 日志文件中？/private/var/log/apache2/dummy-host2.example.com-access_log？如果没有，请为您的 vhost 定义一个，看看它是否存在。如果存在，则您没有 vhost 配置问题，但缺少显示内容、DirectoryIndex 配置不正确或类似问题。
