LNMP environment problem--nginx do not parse PHP file

PHP, Nginx are all installed, configured for a long time is not right. It's just a good whole.

Nginx.conf began to be

server {listen 8080;
        server_name localhost;
        #charset Koi8-r;
        Access_log Logs/host.access.log Main;
        root/users/yangshuo/work/index.php;
            Location/{root HTML;
        Index index.html index.htm index.php;
        } error_page 404/404.html; 
        Error_page 403/error/403.html;
        # REDIRECT Server error pages to the static page/50x.html # Error_page 502 503 504/50x.html;
        Location =/50x.html {root html; } location ~. *\.
            (Eot|otf|ttf|woff) $ {root html;
        Add_header Access-control-allow-origin *;    # 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 $document _root$fastcgi_script_name;
        Include Fastcgi_params;
        # Deny access to. htaccess files, if Apache ' s document Root # concurs with Nginx ' s one #
        Location ~/\.ht {deny all;
 }
        }

later changed to

server {listen 8080;
        server_name localhost;
        root/users/yangshuo/work/index.php;
        Index index.php index.html;

        #charset Koi8-r;

        #access_log Logs/host.access.log Main;
        Location/{try_files $uri $uri//index.php $args;

        } #error_page 404/404.html;
        # REDIRECT Server error pages to the static page/50x.html # Error_page 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$ {
            root/users/yangshuo/work/index.php;
            Fastcgi_pass 127.0.0.1:9000;
            Fastcgi_index index.php; Fastcgi_paraM Script_filename $document _root$fastcgi_script_name;
        Include Fastcgi_params;
        # Deny access to. htaccess files, if Apache ' s document Root # concurs with Nginx ' s one #
        #location ~/\.ht {# deny all;
 #}
    }

Restart and then visit it.

Add index.
