Nginx-Linux Firewall

In the previous blog, after setting the corresponding listening port in the nginx configuration file, the access to nginx may be normal on the server where nginx is located, and access to other servers may fail, this is probably because the configured port is not open for external access. The specific solution is as follows:

Modify iptables (for example, open port 2011)

Add the following statement to/etc/sysconfig/iptables:

-A RH-Firewall-1-INPUT-M state -- state new-m tcp-p tcp -- dport 2011-J accept

Restart iptables: Service iptables restart.

Solve the problem!
