Description of problem:
SELinux is preventing php-fpm from 'map' accesses on the file /home/mikhail/www/ex1/index.php.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that php-fpm should be allowed map access on the index.php file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'php-fpm' --raw | audit2allow -M my-phpfpm
# semodule -X 300 -i my-phpfpm.pp
