ok guys its strange i have tried it many time time but this time my procedure worked:
I tried following:
From 'switch program' i switched to Apache for web and Apache 2.4
cache turned off
then i tried following commands:
sh /script/upcp
then everything start working
one thing i didn't i understand why varnish cache is running when i have turned it off.
