Ansible Install MySql 5.7 - Set Root User Password - Stack Overflow
This response explains a nuance for MySQL 5.7 whereby you can't log in as a root user with no password.

To change the password for a root user for the first time you have to do something like this:

- name: Check if '~/.my.cnf' exists
path: ~/.my.cnf
register: my_cnf_check

- name: Update MySQL root password for all root accounts
name: root
host: "{{ item }}"
password: "{{ mysql_root_password }}"
state: present
check_implicit_admin: "{{ 'no' if my_cnf_check.stat.exists == True else 'yes' }}"
- ::1
- localhost
become: "{{ 'no' if my_cnf_check.stat.exists == True else 'yes' }}"
become_method: sudo

- name: Create MySQL '~/.my.cnf' config file and add root credentials into it
template: src=templates/mysql_my.cnf.j2 dest=~/.my.cnf mode=0600
