Cannot follow external database(MySQL) of openfire server quide

1. I have MySQL database which I created on university's server
2. I try to develop android application that can send msg from mobile through XMPP protocol to keep data at my database server(from 1.)
3. At this time, I already downloaded openfire 3.7.0.dmg(MAC OS X) then try to setup server on my laptop

My problem is I cannot follow Database Installation Guide the error occurred: Does not have mysqladmin command at my Terminal. So, I cannot create table for openfire. Should I need to install MySQL on my laptop ?

Moreover, I pretty much confuse with [YOUR_HOST] of this statement :

jdbc:mysql://[YOUR_HOST]/[DATABASE_NAME]

I don't know what is it? should be localhost or anything?

Anyone can help me ? Thank you so much

You need to have MySQL installed on one computer you have access to. If you want to install it on your Mac, you can either download it directly from mysql.com, or you could install it using a package manager like Homebrew.

Next, make sure your MySQL install can listen for connections over TCP; there's a troubleshooting guide for that.

Next, use the name of the machine your MySQL server is running on in place of [YOUR_HOST]. If it's running on the same machine as OpenFire, you can use localhost.
