How do I change mysql root password?

How to change root mysql password? Easy and clear question, right?

What I tried:

Change root pass in db using:
1. `cd /opt/easyengine/services && docker-compose exec global-db bash -c 'mysql -uroot -p${MYSQL_ROOT_PASSWORD}' `
2. `SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newrootpass');`
3. `flush privileges;`
4. `quit;`
5. `nano /opt/easyengine/services/docker-compose.yml` and change line `MYSQL_ROOT_PASSWORD`
6. manual edit record `global-db` password in `/opt/easyengine/db/ee.sqlite`
7. `ee service restart db`
