当我没初始配在lnmp的时候,用浏览器打开查看php能否解析网页的时出现File not found 不用惊奇让我我们分析一下

    使用php-fpm解析PHP，"No input file specified"，"File not found"是令nginx新手头疼的常见错误，原因是php-fpm进程找不到SCRIPT_FILENAME配置的要执行的.php文件，php-fpm返回给nginx的默认404错误提示。
    一、错误的路径被发送到php-fpm进程
    出现这类错误，十个有九个是后端fastcgi进程收到错误路径(SCRIPT_FILENAME)，而后端fastcgi收到错误路径的原因大都是配置错误。
    常见的nginx.conf的配置如下：
 user  www www;
worker_processes  1;
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
#pid        logs/nginx.pid;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    #log_format  main  ‘$remote_addr - $remote_user [$time_local] "$request" ‘
    #                  ‘$status $body_bytes_sent "$http_referer" ‘
    #                  ‘"$http_user_agent" "$http_x_forwarded_for"‘;
    #access_log  logs/access.log  main;
    sendfile        on;
    #tcp_nopush     on;
    #keepalive_timeout  0;
    keepalive_timeout  65;
    #gzip  on;
    server {
        listen       80;
        server_name  localhost;
        #charset koi8-r;
        #access_log  logs/host.access.log  main;
        location / {
            root   /usr/local/nginx/html;     #指定索引文件的目录
            index  index.html index.htm index.php;
        }
        #error_page  404              /404.html;
        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
         }
        # 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$ {                   #开启php解析
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
           # fastcgi_param  SCRIPT_FILENAME          script$fastcgi_script_name
          改为：
            fastcgi_param  SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;  #指定路径
            include         fastcgi_params;
        }
        # fastcgi_params;
        # deny access to .htaccess files, if Apache‘s document root
        # concurs with nginx‘s one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }
然后在重启nginx，打开浏览器查看php是否能解析网页！
