从本地networking连接到本地apache2服务器

在机器上XI可以连接到127.0.1.1（我有一个php脚本运行在机器X上，调用phpinfo（），它运行良好）。 networking上的X机器IP是192.168.1.101。 我去机器Y，并在浏览器地址栏键入192.168.1.101期望看到p​​hpinput（）输出。 相反，我得到一个“服务器超时”的错误。

不知何故，必须有一种方法将192.168.1.101连接到apache2服务器。 这是什么？ 假定没有防火墙问题。

列出你的httpd.conf文件，看看Apache正在监听什么。 赔率是它只能听本地主机。

cat /etc/httpd/conf/httpd.conf | grep -i listen

如果是这种情况，请添加一行以允许其监听其IP地址或端口。

另一种可能是您的防火墙阻止与您的Web服务器的通信。 iptables -L将消除（或确认）这个概念。
