记得测试之前要关闭防火墙并禁止开机启动！！！！

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
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
body {
width: 35em;
margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif;
}
</style>
</head>
<body>

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
<?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
