问题描述
我使用centOS服务器.我想配置 apache 以侦听端口 8079.我在 httpd.conf 中添加了 LISTEN 8079 指令.
我在 iptables 中打开了 8079 端口并重新启动了 iptables.我什至停止了 iptables 服务.
I use centOS server. I want to configure apache to listen on port 8079.I added LISTEN 8079 directive in httpd.conf.
I opened port 8079 in iptables and restarted iptables. I even stopped iptables service.
"netstat -nal | grep 8079" shows "tcp 0 0 :::8079 :::* LISTEN"
如果我尝试从那台机器访问 http://localhost:8079 或 http://myserver.com:8079，我可以访问该页面.但是从任何其他机器上，我无法通过 80 以外的任何端口访问该站点.在端口 80 上，它可以工作.在端口 8079 上没有.
If I try to access http://localhost:8079 or http://myserver.com:8079 from that machine, I can access that page. BUT from any other machine I am not able to access the site on any port other than 80. On port 80, it works. On port 8079 it does not.
我还需要配置什么?
推荐答案
这是一个防火墙问题.有一个硬件防火墙阻止了对几乎所有端口的访问.(关闭软件防火墙/SELinux bla bla没有效果)
It was a firewall issue. There was a hardware firewall that was blocking access to almost all ports. (Turning off software firewall / SELinux bla bla had no effect)
然后我扫描了开放的端口并使用了开放的端口.
Then I scanned the open ports and used the port that was open.
如果您遇到同样的问题，请运行以下命令
If you are facing the same problem, Run the following command
sudo nmap -T Aggressive -A -v 127.0.0.1 -p 1-65000
它将扫描您系统上的所有开放端口.任何开放的端口都可以从外部访问.
It will scan for all the open ports on your system. Any port that is open can be accessed from outside.
