Why is NGINX is ignoring my query strings?

Question

I recently switched from APACHE to NGINX. However, somewhere along the way NGINX started ignoring my query strings. For example, I use pagination like so:

http://example.com/index.php?page=5

This simply loads example.com as if the query string wasn't there.

Here's the configuration (edited as suggested by Nelson):

/etc/nginx/nginx.conf:

user www-data;
worker_processes 4;
pid /var/run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;
}

http {

    ##
    # Basic Settings
    ##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    ##
    # Logging Settings
    ##

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

    ##
    # Gzip Settings
    ##

    gzip on;
    gzip_disable "msie6";

    # gzip_vary on;

    # gzip_vary on;
    # gzip_proxied any;
    # gzip_comp_level 6;
    # gzip_buffers 16 8k;
    # gzip_http_version 1.1;
    # gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

        # Pass PHP scripts to PHP-FPM
        location ~ \.php {
                include /etc/nginx/fastcgi_params;
                fastcgi_pass 127.0.0.1:9000;
        }

        client_max_body_size 8M;
}

Answer 1

I was having the same problem. I changed the location section in my nginx virtual host file as below and it works fine for me.

location / {
   # try_files $uri $uri/ /index.php;
   try_files $uri $uri/ /index.php$is_args$args;
}

Answer 2

Just use this as Location :

location ~ \.php {
    include /etc/nginx/fastcgi_params;
    fastcgi_pass 127.0.0.1:9000;
}

To be more specific your following two lines are removing the query string:

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
