ocf_heartbeat_mysql-proxy - Manages a MySQL Proxy instance

OCF_HEARTBEAT_MYSQL() OCF_HEARTBEAT_MYSQL()

NAME

ocf_heartbeat_mysql-proxy - Manages a MySQL Proxy instance

SYNOPSIS

mysql-proxy [start | stop | monitor | meta-data | validate-all]

DESCRIPTION

This script manages MySQL Proxy as an OCF resource in a high-availability setup.
The default monitor operation will verify that mysql-proxy is running.
The level 10 monitor operation is left out intentionally for possible future enhancements in conjunction with the admin plugin.
The level 20 monitor operation will perform a SELECT on a given table to verify that the connection to a back-end server is actually working.
Tested with MySQL Proxy 0.8.1 and 0.8.3 on Debian 6.0.
