Thanks Photon...

<quote>Try something like:

shell> bin/safe_mysqld -u user_name &

Where user_name is your MySql login name.

To see if mysqld is running type:

Shell> bin/mysqladmin version

You should see something like:

I was having trouble getting the mysql server started and this tip did the trick but i have a question... I have the start mysql option set to yes in rc.config i believe it is, but it doesnt seem to want to stay on... i tried rcmysql start, it would say ;

starting service MySQL
starting mysql-daemon with database from /var/lib/mysql
021103 09:46:32 mysqld ended

anyway, it would statr and stop really fast. i entered bin/safe_mysqld -u user_name & in the console and it started then left the cursor droped down on the next line with no console prompt so i opened another console window typed rcmysql status and it says running, so cool!

What i would like to know is how to make it do that from start up with out having to type bin/safe_mysqld -u user_name & all the time. also is that the proper way to start mysql server or is it just a way to ensure everything should be working fine. If there is a proper way i wouls sur elike to know. Thanks alot!

pmdamysql

PMDAMYSQL(1)						       Performance Co-Pilot						      PMDAMYSQL(1)

NAME

       pmdamysql - MySQL database PMDA

DESCRIPTION

       pmdamysql is a Performance Co-Pilot PMDA which extracts live performance data from a running MySQL database.

INSTALLATION

       pmdamysql uses a configuration file from (in this order):

       o   /etc/pcpdbi.conf

       o   $PCP_PMDAS_DIR/mysql/mysql.conf

       This file can contain overridden values (Perl code) for the settings listed at the start of pmdamysql.pl, namely:

       o   database name (see DBI(3) for details)

       o   database user name

       o   database pass word

       Once this is setup, you can access the names and values for the mysql performance metrics by doing the following as root:

	       # cd $PCP_PMDAS_DIR/mysql
	       # ./Install

       If you want to undo the installation, do the following as root:

	       # cd $PCP_PMDAS_DIR/mysql
	       # ./Remove

       pmdamysql is launched by pmcd(1) and should never be executed directly.	The Install and Remove scripts notify pmcd(1) when the agent is
       installed or removed.

Binary Status values in text
       Some of the status values are in the form of YES/NO or ON/OFF.

       Since these cannot be intepreted by tools like PMIE, they have been duplicated with a _num extension and the values of 1 (YES/ON) or 0
       (NO/OFF).

   Eg:
       o   mysql.slave_status.slave_io_running

       o   mysql.slave_status.slave_io_running_num

FILES

       /etc/pcpdbi.conf
	   configuration file for all PCP database monitors

       $PCP_PMDAS_DIR/mysql/mysql.conf
	   configuration file for pmdamysql

       $PCP_PMDAS_DIR/mysql/Install
	   installation script for the pmdamysql agent

       $PCP_PMDAS_DIR/mysql/Remove
	   undo installation script for the pmdamysql agent

       $PCP_LOG_DIR/pmcd/mysql.log
	   default log file for error messages from pmdamysql
