对外开放网络端口

背景

想搭建一个内部Npm,在本机的Mac和Ubuntu上,直接搭建完毕,然后监听端口即可

但是在红帽中

 cat /proc/version
Linux version 2.6.32-431.el6.x86_64 ([email protected]) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) ) #1 SMP Fri Nov 22 03:15:09 UTC 2013

本地能curl到,但是外网访问不到

端口开放限制

1. 添加4873可访问端口: /sbin/iptables -I INPUT -p tcp --dport 4873 -j ACCEPT
2. 保存路由表: /etc/rc.d/init.d/iptables save

3. 查看路由表情况

   /etc/init.d/iptables status
   表格：filter
   Chain INPUT (policy ACCEPT)
   num  target     prot opt source               destination
   1    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           tcp dpt:4873
   2    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0           state RELATED,ESTABLISHED
   3    ACCEPT     icmp --  0.0.0.0/0            0.0.0.0/0
   4    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0
   5    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:22
   6    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:80
   7    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:443
   8    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:3306
   9    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:6379
   10   REJECT     all  --  0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited
   
   Chain FORWARD (policy ACCEPT)
   num  target     prot opt source               destination
   1    REJECT     all  --  0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited
   
   Chain OUTPUT (policy ACCEPT)
   num  target     prot opt source               destination
