警告NameVirtualHost *:443没有VirtualHosts

Question

当我重新加载apache时，会出现以下消息：

Reloading web server config: apache2[Tue Dec 30 10:24:04 2014] [warn] NameVirtualHost *:443 has no VirtualHosts

我检查了ports.conf文件，配置如下：

root@li277-183:/etc/apache2# cat ports.conf
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default
# This is also true if you have upgraded from before 2.2.9-3 (i.e. from
# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and
# README.Debian.gz

NameVirtualHost *:80
NameVirtualHost *:443
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>

为什么会出现以下警告，以及如何修复它？

Answer 1

简单地说: Apache正在监听443，但是在这个端口上没有定义VirtualHosts (网站)。(见/etc/apache2/ports.conf)：

NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
    NameVirtualHost *:443
    Listen 443
</IfModule>

<IfModule mod_gnutls.c>
    NameVirtualHost *:443
    Listen 443
</IfModule>

我有两个解决办法：

解决方案1 -启用默认SSL (首选，破坏性较小)在443上定义站点(最简单的方法是运行以下代码)：

ln -s /etc/apache2/sites-available/default-ssl 000-default-ssl

重新启动apache

/etc/init.d/apache2 restart

解决方案2 -从端口443中解除Apache对/etc/apache2/ports.conf的"NameVirtualHost *:443“和"Listen 443”行的注释(例如，从这些行中添加一个#符号，以便新的端口配置文件看起来类似于：)

NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
    # NameVirtualHost *:443
    # Listen 443
</IfModule>

<IfModule mod_gnutls.c>
    # NameVirtualHost *:443
    # Listen 443
</IfModule>
