#!/bin/bash
    date_time=`date +%Y%m%d%H%M`                #every minute
    database=wallet001              #database name
    user=root                       #database username
    password=123456                    #database password
    backup_path=/backup/mysqldata          #backup path
    
    #backup command
     
    /usr/bin/mysqldump -u${user} -p${password} ${database} > ${backup_path}/${database}_${date_time}.sql
    
    # 这里是仅保留最新7天的数据
    find ${backup_path} -mtime +7 -name "${database}_*.sql" -exec rm -f {} \;

shell脚本写完毕之后把他添加到centos的调度器中定时【或间隔】运行即可

crontab -e

添加一条规则：【这里设置的是间隔3小时备份一次】

0 */3 * * * /backup/database_backup_shell.sh
