Page navigation not working in NGINX

Hi Friends,
I recently migrated my site from Apache to Nginx and everything seems to be working except page navigation links on homepage ( mysite.com/page/2). When I click them all of them redirect back to homepage. It might be due to an incorrect redirect setting but I am not able to figure it out and posting it here for help. Here’s my nginx.conf –

server {
    listen       80;
    server_name  mysite.com;

    location / {
        root   /home/userid/public_html;
        index  index.php index.html index.htm;
	 try_files $uri $uri/ @rewrites;
    }

     location @rewrites {
		# Can put some of your own rewrite rules in here
		# for example rewrite ^/~(.*)/(.*)/? /users/$1/$2 last;
		# If nothing matches we'll just send it to /index.php
		rewrite ^ /index.php last;
     }

    error_page  404              /index.php;
    location = /404.html {
        root   /home/userid/public_html;
    }

    error_page   500 502 503 504  /index.php;
    location = /50x.html {
        root   /home/userid/public_html;
    }

    location ~ \.php$ {
        root           /home/userid/public_html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

}

Thanks,
Mick
