centos: nginx + thin webserver, incoming connections not allowed

  • 772

I setup a fresh CentOS 5 install, compile nginx from scratch and am using thin as the rails server.

If I visit the ip adress on the LAN: (for example) 1.2.3.4 I get the website not found error.

However, I can ssh into the machine. If I use links to visit the ip address, I get the landing page.

Any suggestions?

Thanks

EDIT

I ran system-config-securitylevel and then was able to change the security settings to allow incoming connections.

centos nginx

  1. Your firewall is probably blocking it. To open access for port 80 to all traffic, run (as root):

    iptables -A RH-Firewall-1-INPUT -p tcp --dport 80 -j ACCEPT

    To only open traffic for your LAN (or any arbitrary block of IP addresses), add a -s argument with the IP block in CIDR notation. For instance, to open Port 80 for 192.168.0.0-192.168.255.255:

    iptables -A RH-Firewall-1-INPUT -s 192.168.0.0/24 -p tcp --dport 80 -j ACCEPT

    To make that change persist across reboots, add all of the arguments (e.g. everything except iptables) to /etc/sysconfig/iptables, just before the line that begins -A RH-Firewall-1-INPUT -j REJECT.
