Create MySQL dump on EC2 instance and download it
We’re going to create a MySQL dump on an EC2 instance, compress and download this file to our local (Mac) machine.
First of all let’s connect to the instance using a ssh
command:
ssh -i "/path/to/your/*.pem" <EC2_USERNAME>@<PUBLIC_DNS_NAME>
where
/path/to/your/*.pem
is the location where the PEM key is stored.EC2_USERNAME
is the username you log in with. If you used Amazon Linux 2 or the Amazon Linux AMI, the user name is ec2-user.PUBLIC_DNS_NAME
is the IP or DNS alias of the instance.
Then use the mysqldump
utility to export a dump file from the database:
mysqldump -h <AMAZONAWS_RDS_HOST> -u <USER_NAME> -p <DB_NAME> > <BACKUP_NAME>.sql
This file can be compressed
gzip -f <BACKUP_NAME>.sql
Note! -f
option forcefully compresses a file named <BACKUP_NAME>.sql
even if there already exists a file named as <BACKUP_NAME>.sql.gz
.
Use scp
to download the backup file from the EC2 instance to your local machine:
scp -i "/path/to/your/*.pem" <EC2_USERNAME>@<PUBLIC_DNS_NAME>:/path/to/your/backup ~/Downloads/
Note! scp
means “secure copy”, which can copy files between computers on a network.
If needed the backup file can be removed on the EC2 instance:
rm <BACKUP_NAME>.sql.gz
