  3. Default log file directory: /var/log/nginx/
  4. Default document root directory: /usr/share/nginx/html
  5. Default configuration file: /etc/nginx/nginx.conf
  6. Default server access log file: /var/log/nginx/access.log
  7. Default server access log file: /var/log/nginx/error.log

To edit the nginx configuration file, enter:
# vi /etc/nginx/nginx.conf
Set or update worker_processes as follows (this must be set to CPU(s) in your system. Use the lscpu | grep '^CPU(s)' command to list the number of CPUs in the server)

worker_processes 2;Turn on gzip support:

gzip on;Save and close the file. Edit the file /etc/nginx/conf.d/default.conf, enter:
# vi /etc/nginx/conf.d/default.conf
Set IP address and TCP port number:

listen 202.54.1.1.1:80;Set server name:

server_name www.cyberciti.biz;Save and close the file. Start the server:
# service nginx start
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
