通过AWS命令行从AWS RDS导出MySQL转储

我正在尝试从AWS RDS自动获取MySQL备份。我认为使用AWS命令行是有益的，我可以使用EC2 Red Hat上的crontab来自动触发事件

现在的问题是：我如何连接到RDS，备份MySQL，将它放在EC2上，或者复制到S3，让它每晚运行

我不熟悉AWS命令行。请随时提出建议和代码片段

谢谢

您可以使用mysqldump直接从EC2进行备份

编辑RDS实例的安全组，入站规则：

类型：Mysql/Aurora

协议：TCP

港口范围：3306

来源：自定义EC2安全组ID

示例（来源：定制sg_451caa43）

使用SSH连接到EC2实例：

[MacBook Pro:user]$ssh-i keypair.pem ec2-user@PUBLIC_IP

在EC2实例中安装mysql客户端：

[ec2-user@ip-170-10-20-30]$sudo yum安装mysql

[ec2-user@ip-170-10-20-30]$ mysqldump -h db_test.cdsludsd.us-west-2.rds.amazonaws.com -u admin -p my_database > backup_my_database.sql

尝试mysqldump命令

[ec2-user@ip-170-10-20-30]$mysqldump-h RDS\u ENPOINT-u MASTER\u USER\u DATABASE-p DATABASE\u NAME>backup.sql

[ec2-user@ip-170-10-20-30]$ mysqldump -h db_test.cdsludsd.us-west-2.rds.amazonaws.com -u admin -p my_database > backup_my_database.sql

创建cron作业

[ec2-user@ip-170-10-20-30]$ mysqldump -h db_test.cdsludsd.us-west-2.rds.amazonaws.com -u admin -p my_database > backup_my_database.sql

创建cron作业

• 在EC2实例上创建一个cron.sh文件，并将其放在下面的内容中

  mysqldump-h RDS\u ENPOINT-u MASTER\u USER\u DATABASE-p DATABASE\u NAME>/backup/bkp.$（日期+%Y%m%d）。sql

[ec2-user@ip-170-10-20-30]$ mysqldump -h db_test.cdsludsd.us-west-2.rds.amazonaws.com -u admin -p my_database > backup_my_database.sql

• 创建其他文件move_to_s3.sh并放在内容下方

      #!/bin/bash
      echo "starting upload to s3 ..."
      TODAY=$(date +%Y%m%d);
      month=$(date +"%m");
      year=$(date +"%Y");
      bucket="mybkp"
      file="$year/$month/bkp.$TODAY.tar"
      filepath="/backup/bkp.$TODAY.tar"
      resource="/${bucket}/${file}"
      contentType="application/x-compressed-tar"
      dateValue=`date -R`
      stringToSign="PUT\n\n${contentType}\n${dateValue}\n${resource}"
      s3Key=AKIAI7BE3RKNSsdfsdfASF
      s3Secret=sdfksdfkJsdfgd76sdfkljhdfsdfsdfsdf
      signature=`echo -en ${stringToSign} | openssl sha1 -hmac ${s3Secret} -binary | base64`;
  
      RESPONSE=$(curl -w "%{http_code}" -s -X PUT -T "${filepath}" \
              -H "Host: ${bucket}.s3.amazonaws.com" \
              -H "Date: ${dateValue}" \
              -H "Content-Type: ${contentType}" \
              -H "Authorization: AWS ${s3Key}:${signature}" \
              https://${bucket}.s3.amazonaws.com/${file} -o /dev/null $1);
  
      echo $RESPONSE;
      if [ $RESPONSE -ne 200 ] ; then
          echo "There was an issue in transfering DB dbbackup file to S3. Noticed Error Code: $RESPONSE" | mail -s "Issue on transfer to S3" test@gmail.com;
      else
          rm $filepath;
      fi
      echo "finished upload."`
  

在半小时的距离内将两者都设置在cron中

可能的复制可能的复制这足够快吗？我在一个数据库中有大约100GB的数据，我有大约5个这样的数据库。你认为这需要多长时间？这足够快吗？我在一个数据库中有大约100GB的数据，我有大约5个这样的数据库，你认为这需要多长时间？
