# Copyright Abandoned 1996 TCX DataKonsult AB & Monty Program KB & Detron HB
# This file is public domain and comes with NO WARRANTY of any kind
# Mysql daemon start/stop script. Multi-instance enhancements by Tim Bunce.
# Usually this is put in /etc/init.d (at least on machines SYSV R4
# based systems) and linked to
# /etc/rc3.d/S99mysql.svr1
# and /etc/rc0.d/S01mysql.svr1
# When this is done the mysql server will be started when the machine is
# started and shut down when the systems goes down. The '.svr1' suffix can
# be used to identify one of a number of servers. Multiple symlinks can be
# created, one per instance. The 'svrN' suffix can then be used to
# prefix configuration variables in a seperate section of /etc/my.cnf.
# See example below.
#
# A typical multi-instance /etc/my.cnf file would look like:
# [mysqld]
# basedir=...
# key_buffer_size=16M
# max_allowed_packet=1M
# [mysql_multi_server]
# svr1-datadir=/foo1/bar
# svr2-datadir=/foo2/bar
#
# and then the /foo1/bar/my.cnf and /foo2/bar/my.cnf files
# would contain all the *instance specific* configurations.
#
# This script can also be run manually in which case the server instance
# is identified by an extra argument, for example:
# /etc/init.d/mysql stop svr3
#
PATH=/sbin:/usr/sbin:/bin:/usr/bin
export PATH
mode=$1 # start or stop
svr=$2 # eg 'svr1' (optional)
if [ "$2" = "" ]
then name=`basename $0`
