Mac OS X
Mac OS X has introduced yet another way of automatically starting services on a Unix system. It specifically has three different startup directories:
/System/Library/StartupItems
/Library/StartupItems
$HOME/Library/StartupItems
The /System/Library/StartupItems directory is for operating system services, and the $HOME/ Library/StartupItems is for user-owned services. MySQL should start up from /Library/StartupItems, the directory for general services that should be started at system boot time.
The StartupItems directories expect each service to have its own directory, so your first step for MySQL is to create the directory /Library/StartupItems/MySQL. It actually does not matter what you call this directory. Whatever you call it, in it you will place two files:
A Unix script to start MySQL
A startup parameters file called StartupParameters.plist
The Unix script is a simple script that calls the safe_mysqld command to start MySQL. It should have the same name as the directory in which you placed it (in this case, MySQL). It should look something like this:
#!/bin/sh . /etc/rc.common if [ "${MYSQLSERVER:=-NO-}" = "-YES cd /usr/local/mysql bin/mysqld_safe --user=mysql & fi
The check on the value of $MYSQLSERVER
enables you
to turn off MySQL in your Mac OS X
hostconfig
file without having to delete the
MySQL directory from your
StartupItems. To enable MySQL, you need to add
the following line to
/etc/hostconfig:
MYSQLSERVER=-YES-
Similarly, you can stop MySQL from starting ...
