You may want to take a look at /etc/rc.d/init.d/mysql to see were a lot of things are by default, and how they are set. If you leave "pid_file=" blank, it gets set in this file. The file gets created when mysql starts, and contains the Program ID (PID) of the MySQL server.On Tuesday 15 March 2005 11:21, Derek Jennings wrote:

Hi All
I have created a partition on one of my computer to store critical system data files called /System_Data.
I am trying to configure MySQL so that it will use /System_Data as its default file storage.
I looked for /etc/my.cnf; found I did not have one so I generated one.
My /etc/my.cnf files contains exactly 1 line which is: datadir=/System_Data
When I start MySQL I now receive the following error message:
Found option without preceding group in config file /etc/my.cnf at line 1. Fatail error in default handling. Program aborted.
Would appreciate help in ascertaining what should be added or how current should be modified.

It is failing because having created a /etc/my.cnf file it is expecting to find other parameters defined in there in addition to datadir (pid_file=, basedir=/, bindir=/usr/bin )
You could alternatively edit the datadir path in /etc/rc5.d/S90mysql which is the script that starts mysql
Alternatively if you create a symlink from /var/lib/mysql to /mnt/System_Data/mysql then you would not need to change any configuration and your data would go in the folder you desire.
BTW: In Linux /var is the default directory to hold data so why do you need to define a different one?

Hi All and thanks Derek
I have finally gotten back to the above issue in my attempts to resolve my setup issues.
I have printed the instructions for Using Option Files as kindly pointed out to me by David G Stevenson located at:
http://dev.mysql.com/doc/mysql/en/option-files.html
If I understand Derek correctly my.cnf should look something like
[mysql] datadir=/System_Data basedir=/ bindir=/usr/bin pid_file=
This raises two issues to me.
First what is a 'pid_file=' ?
And where is it located?
Second I do not find pid_file, basedir, or bindir mentioned in the MySQL Reference Manual:: 4.3.2 Using Option Files.
Thus to say the least I am confused.
if someone would mind enlighten me on correct procedure I would appreciate it.
Thank Frank
Looking at this file, it looks like this is where you would set your data directory, and you would put my.cfg in the data directory you set in this file.
