I don\'t know why I got this error every time I tried to open the page:
2013/04/06 17:52:19 [error] 5040#0: *1 connect() failed (111: Connection refused) whi
For me the problem was my php-fpm service wasn't running. You can check it by running:
service php-fpm status
and start it by running
service php-fpm start
Sometimes php-fpm might have broken instances running, preventing a restart. This command is a clean way to clear them out and restart php-fpm
killall -9 php-fpm; service php-fpm restart
