# Resource script for haproxy daemon
|

#
|
||||
# Description: Manages haproxy daemon as an OCF resource in
|
||||
# an High Availability setup.
|

#
|
||||
# HAProxy OCF script's Author: Russki
|

|

#
|
||||
#
|
||||
# usage: $0 {start|stop|status|monitor|validate-all|meta-data}
|
||||
#
|
||||
# The "start" arg starts haproxy.
|
||||
#
|
||||
# The "stop" arg stops it.
|
||||
#
|
||||
# OCF parameters:
|
||||
# OCF_RESKEY_binpath
|
||||
# OCF_RESKEY_conffile
|
||||
# OCF_RESKEY_extraconf
|
||||
#
|
||||
# Note:This RA requires that the haproxy config files has a "pidfile"
|
||||
# entry so that it is able to act on the correct process
