編寫shell腳本

#!/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

再給shell執行權限

執行crontab -e

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

重啟crontab
