[lnxa]

server {
    listen       80;
    server_name  www.abc.com;
    #root /data0/www/abc;
    #index index.htm index.html index.php;
    location / {
      root /data0/www/abc;
      index index.htm index.html index.php;
     }
    location /blog/ {
    alias /data0/www/blog/;
    }
    #php fastcgi
    location ~ \.php$ {
        root /data0/www/abc;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        #fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi.conf;
    }

}

http://www.abc.com/blog/index.php error 403

in this case must copy /data0/www/blog to /data0/www/abc? not other idea?
