- # Provides: mysql
- # Required-Start: $local_fs $network $remote_fs
- # Should-Start: ypbind nscd ldap ntpd xntpd
- # Required-Stop: $local_fs $network $remote_fs
- # Default-Start: 2 3 4 5
- # Default-Stop: 0 1 6
- # Short-Description: start and stop Stonedb

- #
- # - Run this script from within the Stonedb installation directory
- # - Create a /etc/my.cnf file with the following information:
- # [mysqld]
- # basedir=<path-to-mysql-installation-directory>
- # - Add the above to any other configuration file (for example ~/.my.ini)
- # and copy my_print_defaults to /usr/bin
- # - Add the path to the mysql-installation-directory to the basedir variable
- # below.
- #
- # If you want to affect other Stonedb variables, you should make your changes
- # in the /etc/my.cnf, ~/.my.cnf or other Stonedb configuration files.
-
- # If you change base dir, you must also change datadir. These may get
- # overwritten by settings in the Stonedb configuration files.
