我的 Linux 机器无法通过 IP 地址访问，仅如
http://127.0.0.1:8080/projectname
或 localhost 在浏览器上工作，但是
http://10.1.5.5:8080/projectname
不是（这里 10.1.5.5 是我通过ifconfig在终端中输入找到的 IP 地址）。
我使用的是 Fedora 16。

答案1
您的盒子有多个接口。每个接口可以有多个IP 地址。 （其中，lo 上有 127.0.0.1，eth0 上有 10.1.5.5，或类似的东西。 - 请参阅ip addr获取详细信息。）
现在，您已经在那个盒子上运行了某种 Web 服务器。要让其他人可以访问它，它必须绑定到某些接口或 IP 地址。
在 Web 服务器的配置文件中的某个位置，您应该找到一个“监听”或“绑定”选项，指定服务器绑定的地址。
目前它似乎只绑定到127.0.0.1，即只能通过环回接口从您自己的盒子访问它。 （netstat -tpln详情请参阅。）
如果您想让它可以从任何地方进行更改，通常可以将其绑定到“*”或“0.0.0.0”。 - 查看您的配置文档。
