Mail Server Setup With Exim, MySQL, Cyrus-Imapd, Horde Webmail On Centos 5.1

I am on page 2 of the setup and in the mysql setup:

I run:

/usr/bin/mysqladmin -u root -h impi password 'password' -p

And receive this error:

/usr/bin/mysqladmin: connect to server at 'impi' failed
error: 'Unknown MySQL server host 'impi' (1)'
Check that mysqld is running on impi and that the port is 3306.
You can check this by doing 'telnet impi 3306'

What gives?

 

Is impi the correct hostname? Is it listed in /etc/hosts?
What's the output of

Code:

netstat -tap | grep mysql

?
