这是我第一次安装Linux/Apache。我在连接到LAN的机器上安装了CentOS和LAMPP。
关闭了 http 和 mysql（因为我不想与 LLAMPP 冲突）
chkconfig httpd off
chkconfig mysqld off
然后 LAMPP 成功启动
/opt/lampp/lampp start

问题：无法连接 - Firefox 无法与 179.16.51.36 的服务器建立连接。
我需要一些指点，以知道下一步该看哪里。
error_log 文件中没有错误（只有一些警告）
我可以 ping 服务器。

答案1
从机器上运行telnet localhost 80。这样有效吗？如果有效，则表明您的 Web 服务器正在端口 80 上运行，这是应该的。但从您的描述来看，这似乎不起作用。
检查/var/log/messages一下是否打印了任何有用的内容。
这XAMPP 页面有一些进一步的故障排除技巧。不过，我猜你会在 /var/log/messages 中找到一些系统日志消息，它们应该能为你指明正确的方向。
答案2
确保您的 iptables 允许端口 80 上的传入连接。
运行iptables -L -nv并确保您有如下一行：
2383 138K 接受 tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:80
在您的输入表中。
答案3
我看到您正在尝试通过浏览器中的 179.16.51.36 ip 进行连接，并且您正在通过 localhost 检查服务器。您能判断在浏览器中加载 localhost 是否有效吗？如果客户端和服务器是不同的主机。那么您应该检查从客户端到端口 80 上的服务器 ip 的 telnet 是否正常工作？
答案4
在尝试通过网络访问 Apache 之前，您应该验证它是否已正确启动。
netstat -ntlp
在服务器上运行上述程序，它应该列出哪些服务正在运行以及它们“绑定”到哪些端口。
如果没有列出 80，那么您需要排除 apache 启动故障。
apachectl configtest
apachectl start
在初始测试期间暂时关闭服务器的 iptables 防火墙会有所帮助。
/etc/init.d/iptables stop
