mysql数据定期备份删除

Posted 2020-10-11 layfork

编写shell脚本

#!/bin/bash
#
# This is a ShellScript For Auto DB Backup and Delete old Backup
#
backupdir=/webserver/mysqlbackup
time=` date +%Y%m%d%H `
/webserver/software/mysql/bin/mysqldump -u user -ppassword  ybjc | gzip > $backupdir/name$time.sql.gz

#delete
find $backupdir -name "name_*.sql.gz" -type f -mtime +5 -exec rm {} \; > /dev/null 2>&1

 

再给shell执行权限

 

执行crontab -e

 15 11 * * * cd /home/loganalysis/ && ./dealexcel.sh >> /home/loganalysis/error.log 2>&1

 

重启crontab
