In addition, after installing mysql-server through apt-get install today, create a user

grant all privileges on mycms.* to joolma@'%' identified by '123456';flush privileges;

I couldn't connect to the database by running the mysql-h localhost-u joolma-p command. after searching for the database online for half a day, I found that I needed another command.
Grant all privileges on mysql. * to joolma @ 'localhost' identified by '123 ';
Grant permissions on localhost. I remember that in windows, the previous command can be done. in linux, two commands are required.
