DocumentRoot接受一个参数，即文档树错误的根目录

Question

好的，我在我的电脑xubuntu上有这个linux操作系统，外部IP不能通过内部或外部网络工作，也不能在我的pc上工作。只是说404找不到。我能做什么?

这是000-default.conf，我还尝试了/var/www/html：

Servername 
ServerAdmin webmaster@localhost
DocumentRoot "/var/www"            # try quoting
DirectoryIndex index.html               # just in case
ErrorLog /var/log/apache2/error.log        # fully specified
CustomLog /var/log/apache2/acces.log      # fully specified
             # quoted
    AllowOverride All
    Require all granted                 # required in Apache 2.4

这是error.log：

在systemctl状态apache2，我得到

你还需要什么信息？我必须指出，在/var/www/目录中有一个index.html！

Answer 1

上面共享的配置似乎是来自更大的conf的一个片段，或者是整个conf中包含的一个文件。如果您在“默认”vhost的某个地方有另一个conf，则不使用指定的"ServerName“或"ServerAlias”就无法浏览该vhost。

我怀疑您定义的vhost不是apache用来处理请求的vhost。

默认情况下，除非定义_default_ vhost，否则Apache将使用第一个被读取为默认的vhost配置。考虑到这一点，这就是为什么我总是用唯一的日志文件创建vhost的100%原因。它使这些事情更易于调试。

例如：

  DocumentRoot /blah/blah
  DirectoryIndex index.html
  ErrorLog ${APACHE_LOG_DIR}/default.error.log
  LogLevel warn
  CustomLog ${APACHE_LOG_DIR}/default.access.log combined

和/或

  DocumentRoot /blah/blah
  ServerName blah.blah.blah
  DirectoryIndex index.html
  ErrorLog ${APACHE_LOG_DIR}/blah.blah.blah.error.log
  LogLevel warn
  CustomLog ${APACHE_LOG_DIR}/blah.blah.blah.access.log combined
