记得测试之前要关闭防火墙并禁止开机启动！！！！

[root@centos6 local]# iptables -F

1.安装好LNMP之后，使用浏览器访问服务器IP可以看到Nginx的欢迎页，证明安装成功。

2.这个欢迎页原文件在/nginx/html/目录下，这个目录下的文件可以直接被访问。

[root@centos6 nginx]# cd html

[root@centos6 html]# ls

50x.html  index.html

[root@centos6 html]# cat index.html |less

Welcome to nginx!

If you see this page, the nginx web server is successfully installed and

working. Further configuration is required.

3.要想解析php文件，需要编辑Nginx配置文件

[root@centos6 nginx]# vim /usr/local/nginx/conf/nginx.conf

4.去掉php配置前面的注释符#，并更改网站根目录

……

# proxy the PHP scripts to Apache listening on 127.0.0.1:80

       #

       #location ~ \.php$ {

       #    proxy_pass   http://127.0.0.1;

       #}

       # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

       #

       location ~ \.php$ {

           root           html;

           fastcgi_pass   127.0.0.1:9000;

           fastcgi_index  index.php;

           fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;

           include        fastcgi_params;

       }

……

4.重新加载nginx配置文件：

[root@centos6 html]# nginx -s reload

5.在网站根目录/usr/local/nginx/html/下添加一个info.php文件：

[root@centos6 html]# vim info.php

phpinfo();

?>

6.使用浏览器看到已经可以解析PHP

7.使用curl测试，默认访问的是index.html

[root@centos6 html]# curl localhost

8.使用curl测试info.php

[root@centos6 html]# curl localhost/info.php
