Amazon RDS MySQL gives simple methods of bringing information into the DB and trading information from the DB. After we can effectively associate with the MySQL information base we can utilize CLI instruments to run the import and fare orders to get the information from different sources all through the RDS data set. The following are the situations to consider when settling on the way to deal with the import the information into the Amazon RDS - MySQL data set.
From an Existing MySQL data set
A current MySQL DB can be available on reason or in another EC2 example. Diagrammatically what we do is appeared underneath.
Making a reinforcement from On-Premise DB
As an initial step we make a reinforcement of the on-premise information base utilizing the underneath order.
mysqldump -u user -p[user_password] [database_name] > backupfile.sql
A record with name backupfile.sql is made which contains the table design alongside the information to be utilized.
Putting away the reinforcement record in S3.
Transfer the reinforcement record made above to a pre-chosen Amazon S3 can in a similar area where the objective RDS MySQL DB information base is available. You can follow this connect to find out about how to transfer.
Import information from Amazon S3 to RDS-MySQL data set
You can utilize the accompanying Amazon CLI order to import the information from S3 to MySQL DB.
aws rds restore-db-instance-from-s3 \ --allocated-storage 125 \ --db-instance-identifier tddbidentifier \ --db-instance-class db.m4.small \ --engine mysql \ --master-user-name masterawsuser \ --master-user-password masteruserpassword \ --s3-bucket-name tpbucket \ --s3-ingestion-role-arn arn:aws:iam::account-number:role/rolename \ --s3-prefix bucketprefix \ --source-engine mysql \ --source-engine-version 5.6.27
From Another RDS-MySQL Instance
There might be situations when you need information from a current RDS MYSQL DB to be taken into another RDS MYSQL DB. For instance, to cerate a Disaster recuperation DB or make a DB just for business announcing and so on In such situation, we make read reproductions which are a duplicate of their source DB and afterward elevate that read imitation to another DB occasion. They are utilized to keep direct hefty read from the first source DB when we need to duplicate the information.
make a read-reproduction
aws rds create-db-instance-read-replica \ --db-instance-identifier myreadreplica \ --source-db-instance-identifier mydbinstance
Elevate a Read reproduction to DB Instance
Presently as we have the reproduction, we can elevate it to an independent DB case. This will serve our end need of bringing in information from o RDS – Mysql DB to another one. The accompanying order is utilized to finish the advancement of a read imitation to a db occasion.
aws rds create-db-instance-read-replica \ --db-instance-identifier readreplica_name \ --region target_region_name --db-subnet-group-name subnet_name --source-db-instance-identifier arn:aws:rds:region_name:11323467889012:db:mysql_instance1
From Any Database
To import information from some other data set to Amazon RDS – MySQL, we need to utilize the amazon Data Migration Service additionally called Amazon DMS. It utilizes Schema change instrument to interpret the current information base to a the MYSQL stage. The beneath chart clarifies the general cycle. Likewise it chips away at the comparable rule of replication as portrayed in the past area.
Sending out Data from MySQL
Sending out of information from Amazon RDS Mysql DB is a straight advances measure where it deals with a similar replication guideline we have seen previously. The following are the means to complete the fare cycle.
- Start the example of MySQL running outer to Amazon RDS.
- Assign the MySQL DB example to be the replication source.
- Use mysqldump to move the information base from the Amazon RDS example to the occasion outer to Amazon RDS.
The following is the code for the mysqldum order
mysqldump -h RDS instance endpoint \ -u user \ -p password \ --port=3306 \ --single-transaction \ --routines \ --triggers \ --databases database database2 \ --compress \ --compact | mysql \ -h MySQL host \ -u master user \ -p password \ --port 3306
