I recently started delving into building a Zope3 + MySQL application on Ubuntu Dapper. Here are the steps I had to do:

I've elided starting and stopping the Zope3 process, the false starts, and dead ends.

        Install the zope3-sandbox package, which gets all dependencies for Zope3, and sets up a sandbox instance at /var/lib/zope3/instance/sandbox/

        Add my Ubuntu login user to the 'zope' group (makes editing easier).
        Make sure the sandbox and all subfolders are writable by group:
                sudo chmod -R g+w /var/lib/zope3/instance/sandbox/

        install mysql-server package

        install mysql-client package

        install mysqladmin package

        Install setuptools with ez_setup.py, as described here:
                http://peak.telecommunity.com/DevCenter/EasyInstall#installation-instructions

        Install SQLObject by running:
                sudo easy_install 'sqlobject'
                (this is because the Dapper package of SQLObject conflicts with SQLOS)

        Install SQLOS (Zope3 SQLObject Support) by running:
                sudo easy_install 'sqlos'

        Download a tarball of SQLOS:
        http://cheeseshop.python.org/pypi/sqlos/

        From the tarball, extract the four files
        in /sqlos-0.2.1/includes/ to /var/lib/zope3/instance/sandbox/etc/package-includes/

After that, I had to do some fiddling to get the sample app included with SQLOS working with MySQL:

        Go to /var/lib/zope3/instance/sandbox/lib/python/ and do a subversion checkout of the MySQLdbDA trunk:
                svn co svn://svn.zope.org/repos/main/mysqldbda/trunk mysqldbda

        Create a file named 'mysqldbda-configure.zcml'
        inside /var/lib/zope3/instance/sandbox/etc/package-includes/
        with the following contents:
                <include package='mysqldbda' />

Edit /usr/lib/python2.4/site-packages/sqlos-0.2.1-py2.4.egg/sqlos/ftesting.zcml to use the 'mysql' DB adapter predefined in the file instead of the 'sqlite' one.

        Added a testdb to MySQL, and a testuser (with a password of testuser) with full privileges on that DB:
                mysqladmin --user=root -p create testdb

                mysql> grant select, insert, update, create, alter,
                delete, drop ON testdb.* to testuser@localhost
                identified by 'testuser';

        Create the required sample_person table:
                CREATE TABLE `sample_person` (
                  `fullname` varchar(50) NOT NULL default '',
                  `username` varchar(20) NOT NULL default '',
                  `password` varchar(20) NOT NULL default '',
                  `id` int(11) NOT NULL auto_increment,
                  PRIMARY KEY (`id`)
                ) ENGINE=MyISAM DEFAULT CHARSET=latin1

                Create the required dog and sample_isolated_person tables: (details elided)

After accomplishing all of that, Zope now has a new 'SQLObject MultiContainer' available that you can add through the web, and to which you can then add simple 'Person' objects that are persistent in the table. Adding a second container shows the same person objects as exist
in the first. Deleting a person deletes the record. Deleting the containers does not.

After deleting all the added containers, deleting the
sqlos.ftesting-configure.zcml file from /var/lib/zope3/instance/sandbox/etc/package-includes disables the sample app objects from being addable in Zope.

The following enhancements are requested:

1) Add a package to Ubuntu for MySQLdbDA, so a subversion source checkout is not necessary (Debian bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=345831)

2) Updating SQLObject under Dapper to 0.7 in order to support SQLOS. (Edgy has the newer version)

3) Add a package to Ubuntu for SQLOS for gluing Zope3 and MySQL together via SQLObject.
