Nginx+php-fpm: sometimes another virtual host opens, how to fix it?

Question

PHP

There is a bunch of php-fpm + nginx on centos 7.
There are several virtual hosts.
Each host with its own pool

pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 2
pm.max_spare_servers = 3

The following problem occurs:
Opening one domain may open a page from another virtual host.
Who is to blame for this behavior, nginx or php-fpm and how to fix it?

Answer 1

Most likely it is in the nginx host settings, document_root points to the folder with the site root.

Answer 2

The culprit is definitely nginx, or rather your configs.

Answer 3

Good afternoon!
And by chance, the site that should not open, but is opened by default is not? It happened to me when the site in NGINX was set to ipisheng by default (in addition to the site name, ipisheng was specified in the name service)

Answer 4

Despite the opinions of local analysts, php-fpm was to blame .
Namely, the joint use of chroot and optimizer (in my case, zend-opcache).
