FastCGI error

[jazomand]

When I changed phpmyadmin's port on a fresh install, I get this error on nginx: nginx:[emerg] open() "/etc/nginx/fastcgi.conf" failed (2: No such file or directory)

In order to fix this, I had to create the file: opt/ajenticp/ajenti/etc/nginx/fastcgi.conf
And writed this line in it:
include /etc/nginx/fastcgi_params;
