不自动清理relay log 用作业的方式清理

清理时调用 mha_node 工具 purge_relay_logs

cat purge_relay_log.sh 


#!/bin/bash

user=root

passwd=123456

port=3306

log_dir='/data/masterha/log'

work_dir='/data'

purge='/usr/local/bin/purge_relay_logs'


if [ ! -d $log_dir ]

then

   mkdir $log_dir -p

fi


$purge --user=$user --password=$passwd --disable_relay_log_purge --port=$port --workdir=$work_dir >> $log_dir/purge_relay_logs.log 2>&1
