I wonder what is the differences between mysql-client and mysql-client-core? Also there are mysql-server and mysql-server-core.

Now I'm using mysql-client-5.5 and mysql-client-core-5.5 on Ubuntu12.04 LTS.

I entered following commands, and retrieved the results.

As you can see it, mysql-client package includes the client binaries and the additional tools innotop and mysqlreport, but mysql-client-core only includes the core client files as /usr/bin/mysql, /usr/bin/mysqlcheck.

And about mysql-server.

This is an empty package that depends on the current "best" version of mysql-server (currently mysql-server-5.5), as determined by the MySQL maintainers.(mysql-server)

This package includes the server binaries but doesn't contain all the infrastructure needed to setup system databases.(mysql-server-core)

mysql-client-core - containts core client binaries for mysql database support while
mysql-client - depends on mysql-client-core and contains other extended features and utilities (for ex perl support)
