vi /etc/nginx/nginx.conf



Verify that everything is working:
# netstat -tulpn | grep :80
# ps aux | grep nginx



Firewall configuration: Open TCP port # 80

Edit the file /etc/sysconfig/iptables, enter:
# vi /etc/sysconfig/iptables

Add the following lines, ensuring that they appear before the final LOG and DROP lines for the INPUT chain to open port 80:

-A INPUT -m state --state NEW -p tcp --dport 80 -j ACCEPT
Save and close the file. Finally, restart the firewall:
# service iptables restart
