Where is the MySQL 5.7 my.cnf file located?

Question

In Ubuntu, I had a my.cnf file from MySQL 5.6 in /etc/my.cnf. But I can not find the same MySQL 5.7 file. How can I find this?

I found the whole search / (root). But I could not find him anywhere. Any clues?

I am trying to set the value of max_connections.
