如何诊断在 Fedora 上访问 Apache 站点的问题？
我删除了 /var/log 中的所有内容，然后重新启动了 rsyslog 和 httpd。然后cat /var/log/messages显示：

我的 /etc/httpd/sites-enabled/mydomain.conf 中仅启用了一个站点：
<VirtualHost *:80>
ServerName www.mydomain.com
ServerAlias mydomain.com *.mydomain.com
DocumentRoot /usr/local/mydomain
RewriteEngine On
AllowEncodedSlashes On
Alias /media/ /usr/local/mydomain/media
<Directory /usr/local/mydomain>
Options FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
</VirtualHost>
运行netstat -tulpn显示httpd已绑定到80端口。
在我的 /etc/hosts 中我有：
192.168.1.2 www.mydomain.com
这是服务器的域。
我还在服务器上禁用了 iptables service iptables stop。
我有一个用于测试的示例文件cat /usr/local/mydomain/media/test.txt：：
hello world
但是当我访问http://www.mydomain.com/media/test.txt我收到“Firefox 无法与 www.mydomain.com 的服务器建立连接”的提示，好像服务器根本没有运行。
我在 /var/log/messages 或 /var/log/httpd/error.log 中没有看到任何错误消息。我做错了什么？
答案1
您必须提供多一点的信息 - 确保端口可访问，您是否能够显示默认的 apache“它有效”页面，您还可以尝试从其他框的命令行连接到端口 80 上的此框，看看您是否可以连接。
