Nginx. LOG:

The Nginx configuration file is as follows:

Also, there is no problem in executing a single PHP file, and Phpinfo can see that the added extension is already installed

Do not install packages with one click.
PHP Installation 5.4 or later
fastcgi use Ip:port. Do not use Unix:sock

Script_name uses $document_root configuration, for example:

fastcgi_params SCRIPT_NAME $document_root$fastcgi_script_name;
