Nginx 502, where to look for the problem?

Question

PHP

Good evening.
Updated PHP from 5.2 to 5.6.7 today.
After that, nginx started to give a 502 error
. The logs are clean, there are no errors.
/var/log/nginx/error.log
/var/log/php-fmp.log
When accessing site.com/test. php , we get 502. Stupidly in the phpinfo file
When accessing site.com/test. html - everything is fine
www.conf

user = www-data
group = www-data
listen = /var/run/php5-fpm.sock ;Файл создается

listen.owner = www-data
listen.group = www-data
listen.mode = 0660

Answer 1

You missed the line that asked to replace www.conf
check it, look for the line ending in .sock or port 9000
