How to install two Site of wordpress on the same NAS/Server

I hope it’s a simple question I posted on my website in wordpress on my NAS in the \ wordpress on the same NAS always wanted to publish a second site in the \ wordpress2 so I exported the mysql database of the main site
I replaced all the references in the database to the new location http://dominio/wordpress2 then I imported in mysql with the name database2, I went to the \ wordpress2 and I edited the wp-config.php with the reference to the new database define (‘DB_NAME’, ‘database2’);
But now from the outside by typing http://miodominio/wordpress2 I access the home page but I lost all references to imaggini and if I click on any page of the site gives me the error page you requested was not found.

Where am I wrong?
Thank you for the support that you will give me
