自动备份mysql脚本,备份mysql脚本

创建备份文件存放的目录

mkdir /usr/local/dbbak

脚本:vi /usr/local/mysqlback.sh

# /bin/bash

DB_NAME="dsideal_db"

DB_USER="root"

DB_PASS="123456"

BACK_DIR="/usr/local/dbbak"

DATE="$DB_NAME-`date +'%Y-%m-%d=%H:%M:%S'`"

LogFile="$BACK_DIR"/dbbakup.log #日志记录保存的目录

BackNewFile=$DATE.sql

mysqldump --opt --force -u$DB_USER -p$DB_PASS $DB_NAME > $BACK_DIR/$DATE.sql

echo -----------------------"$(date +"%y-%m-%d %H:%M:%S")"----------------------- >> $LogFile

echo createFile:"$BackNewFile" >> $LogFile

find "/usr/local/dbbak/" -mtime +7 -type f -name "*.sql" -print > deleted.txt

echo -e "delete files:n" >> $LogFile

#循环删除匹配到的文件

cat deleted.txt | while read LINE

do

rm -rf $LINE

echo $LINE>> $LogFile

done

echo "---------------------------------------------------------------" >> $LogFile

给sh脚本增加权限

chmod 777 /usr/local/mysqlback.sh

利用crontab，每天凌晨3点定时执行

crontab -e

0 03 * * * /usr/local/mysqlback.sh > /dev/null 2>&1

【备注】简单的备份

mysqldump --databases test --flush-logs> /usr/local/backup-`date +%F-%H-%M`.sql
