```sql
apt-get install mysql-server

create database db;
create table db.test(a Int);

CREATE USER 'myuser'@'%' IDENTIFIED BY 'mypass';
GRANT ALL ON *.* TO 'myuser'@'%';
FLUSH PRIVILEGES;
```

mysql client shows different error messages in case the wrong password/user VS host:port
```
# mysql -h 127.0.0.1 -u myuser --password=mypass1
ERROR 1045 (28000): Access denied for user 'myuser'@'localhost' (using password: YES)

mysql -h 127.0.0.1 --port 9999 -u myuser --password=mypass
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1:9999' (111)
```

clickhouse shows the same error message

```
