我想设置phppgadmin，postgresql已经完成-通过以下this article完成
但我有nginx，
到目前为止，我做了以下配置：

ln -s /usr/share/phppgadmin /var/www

和
/etc/nginx/sites-available/phppgadmin：

server{
    listen 85;
    server_name     pgadmin.mypage.com;
    root            /var/www/phppgadmin;
    index index.html index.html index.php;

    access_log      /var/log/phppgadmin/access.log;
    error_log       /var/log/phppgadmin/error.log;

    location / {
            allow   my_page_IP;
            deny    all;
    }
    location ~ /\.ht {
            deny all;
    }

    location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /var/www/phppgadmin$fastcgi_script_name;
            include /etc/nginx/fastcgi_params;
    }
 }

和

ln -s /etc/nginx/sites-available/phppgadmin /etc/nginx/sites-enabled/

和

service nginx restart

但我得到的是：

403 Forbidden

错误日志显示：

2015/03/21 18:06:14 [error] 16916#0: *1 access forbidden by rule, client: 188.194.97.247, server: pgadmin.mypage.com, request: "GET / HTTP/1.1", host: "my_page_IP:85"

何月道：

chmod -R 775 phppgadmin/ 
chown -R www-data:www-data phppgadmin/

但还是一样的403消息，我做错了什么？
