My message was voluminous, because I've been trying to get this to  
work for several days, and had no luck getting docs that explained  
the setup used by MacPorts. While I was waiting for this reply I  
downloaded the MySQL for OSX from MySQL.com and got it running in  
about 20 minutes, and within a brief time after that I had imported  
all my data.

It uses a fairly simple hierarchy:


MacPorts appears to use several directories, which probably all need  
to have the ownership/permissions set correctly :


I am sure there is a great reason for the over-complicated hierarchy  
which I do not see at this point, but the standard install where all  
the mySQL stuff goes in one dir seems a lot easier to deal with, even  
for browsing purposes. Although as a work-around I could create a  
dummy directory with aliases to all these other directories in order  
to simplify the process of becoming familiar with the distributed  

Setting permissions for the installations at /usr/local/mysql was  
fairly simple and only involved two sets of permissions, one for the  
main directory, and a different one for the data dir, and like I said  
previously I got that version up and running in about 20 minutes, vs  
several days that I've been trying to get the MacPorts MySQL working.  
I am not trying to be ungrateful, I am just not sure why this  
implementation is so over-complicated ?

/usr/local/mysql/data   --> data file, which translates to -->  /opt/ 

I didn't find any documentation on this type of setup. All the docs I  
found refer to the /usr/local/mysql self contained type of installation.

  I was not able to locate any documentation on what the MacPorts  
implementation required, such as my.cnf, and where any of this stuff  
is supposed to live.

I ask again, Is there any documentation ?

Also the log showed this :


070624 18:11:24  mysqld started
070624 18:11:24 [ERROR] /opt/local/libexec/mysqld: unknown option '-S'

070624 18:11:24  mysqld ended

070624 18:40:58  mysqld started
070624 18:40:58 [ERROR] /opt/local/libexec/mysqld: unknown option '-S'

070624 18:40:58  mysqld ended

You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl

Also, has anybody documented how they got this implementation working ?

Are there any step by step docs for this implementation ?

  Any ideas ?
