Step 3: Configuration files

• Default configuration directory: /etc/nginx/
  
• Default SSL and vhost config directory: /etc/nginx/conf.d/
  
• Default log file directory: /var/log/nginx/
  
• Default document root directory: /usr/share/nginx/html
  
• Default configuration file: /etc/nginx/nginx.conf
  
• Default server access log file: /var/log/nginx/access.log
  
• 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       80;
　　

　　Set server name:
　　

　　
server_name  www.test.com;
　　

　　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
