apache - 如何调试apache虚拟主机配置？

Question

我的 apache 虚拟主机配置再次出现问题。 (使用默认配置而不是我的特定配置)。

问题不在于配置错误，而在于如何解决它。

有人有好的建议可以快速解决此类问题吗？

默认的conf文件是这个:

NameVirtualHost *
<VirtualHost *>
        ServerAdmin webmaster@localhost

        DocumentRoot /var/www/
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
        </Directory>

        ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
        <Directory "/usr/lib/cgi-bin">
                AllowOverride None
                Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
                Order allow,deny
                Allow from all
        </Directory>

        ErrorLog /var/log/apache2/error.log

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn

        CustomLog /var/log/apache2/access.log combined
        ServerSignature On

    Alias /doc/ "/usr/share/doc/"
    <Directory "/usr/share/doc/">
        Options Indexes MultiViews FollowSymLinks
        AllowOverride None
        Order deny,allow
        Deny from all
        Allow from 127.0.0.0/255.0.0.0 ::1/128
    </Directory>

</VirtualHost>

不适用的虚拟主机配置是这个:

<VirtualHost *:*>

ProxyPreserveHost On
ProxyPass / http://ip.ip.ip.ip:8088/
ProxyPassReverse / http://ip.ip.ip.ip:8088/
ServerName wiki.mydomain.com

</VirtualHost>
