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！

还有一个原因就是因为文件名大小写问题导致的
