# Opencaching replication monitor bash script
|
|
#
|
|
# This script writes every 10 seconds the current timestamp to
|
|
# table sys_repl_timestamp. This enables the cron-module
|
|
# repliaction_monitor to check if the mysql replication slave(s) is up to
|
|
# date and online.
|
|
#
|
|
# You should place this bash script outside the PHP configured
|
|
# open_basedir restriction and place a cronjob entry that
|
|
# executes every 5 minutes or place it in rc.3 or rc.5
|
|
# (run this script on the master database server, not on any slave!)
|
|
#
|
|
# If you setup a cronjob call it with parameter "-q" to prevent
|
|
# output of running-message.
