設定 Nginx 伺服器支援 PHP

小弟根據這篇文章: http://blog.gtwang.org/iot/raspberry-pi-nginx-rtmp-server-live-streaming/ 完成 Nginx 伺服器的架設和串流視訊影像，
然後我又參考了另一篇文章 http://tonyhack.familyds.net/wordpress/?p=4173
，想要設定 Nginx 支援 php ，
但不知為何，每次我用瀏覽器連結到 index.php 或其他附檔名為 php 的檔案，都會出現以下畫面:



我的 nginx.conf 的內容是:

#user nobody;
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 b0241030.dlinkddns.com;

#charset koi8-r;

#access_log logs/host.access.log main;

location / {
root /var/www;
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$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
# NOTE: You should have “cgi.fix_pathinfo = 0;” in php.ini

# With php5-cgi alone:
# fastcgi_pass 127.0.0.1:9000;
# With php5-fpm:
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}


# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;

# location / {
# root html;
# index index.html index.htm;
# }
#}


# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;

# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;

# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;

# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;

# location / {
# root html;
# index index.html index.htm;
# }
#}

}

rtmp {
server {
listen 1935;
ping 30s;
notify_method get;
application rtmp {
live on;
}
}
}

不知是哪個環節出了錯，還請大家指點指點，小弟感激不盡 ! ! !


我的 error.log 的內容是:

，但我看不太懂，麻煩各位指點指點 !!!
