配置文件的目录；

Step #4: Configuration files

1. Default configuration directory: /etc/nginx/ nginx的目录
2. Default SSL and vhost config directory: /etc/nginx/conf.d/   SSL协议 和 虚拟机
3. Default log file directory: /var/log/nginx/ 日志目录
4. Default document root directory: /usr/share/nginx/html 默认的首页
5. Default configuration file: /etc/nginx/nginx.conf nginx的配置文件
6. Default server access log file: /var/log/nginx/access.log  nginx的访问日志
7. Default server access log file: /var/log/nginx/error.log nginx的错误日志

To edit the nginx configuration file, enter:
# vi /etc/nginx/nginx.conf根据你的系统的cpu数量设置 worker_processes  数量
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:

配置监听地址和端口号

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
