自动打包mysql下binlog日志

Posted 2020-08-19

一、需求

线上一台机器做了rsync,从5台mysql机器拉取binlog日志到本地，之前是手动打包，现在写了个脚本，放到crontab定期执行打包，并删除打包后的的文件。

二、脚本如下

#!/bin/sh
# usage: 
# nohup sh /tmp/backup_binlog_tar.sh > nohup.out  2>/dev/null  &


dir_backup_tar="/data0/backup_log-bin_tar"_`date +%Y-%m-%d--%H-%M-%S`
echo $dir_backup_tar
mkdir -p $dir_backup_tar

#!/bin/sh
# usage: 
# nohup sh /tmp/backup_binlog_tar.sh > nohup.out  2>/dev/null  &


dir_backup_tar="/data0/backup_log-bin_tar"_`date +%Y-%m-%d--%H-%M-%S`
echo $dir_backup_tar
mkdir -p $dir_backup_tar


dir_binlog_140="/data0/backup_log-bin/140/log-bin"
dir_binlog_141="/data0/backup_log-bin/141/log-bin"
dir_binlog_145="/data0/backup_log-bin/145/log-bin"
dir_binlog_146="/data0/backup_log-bin/146/log-bin"
dir_binlog_182="/data0/backup_log-bin/182/log-bin"


instance_seq=140
dir_binlog=$dir_binlog_140
if [ ! -d $dir_binlog ]; then
        echo "$dir_binlog is not exit and skip!" 
fi
for instance in `ls $dir_binlog`
do
        cd $dir_binlog
        tar -zcf $dir_backup_tar/"$instance_seq""_""$instance"".tar.gz" $instance
        if [ $? -eq 0 ];then
                echo "delete $dir_binlog/$instance/* ..."
                rm -rf $dir_binlog/$instance/*

done
