You Should Know:
Here are some practical commands and code snippets related to AWS Aurora and database management that you can use to deepen your understanding:
1. Connecting to Amazon Aurora MySQL:
mysql -h <cluster-endpoint> -u <username> -p
2. Creating a Read Replica in Aurora:
CREATE DATABASE replica_db AS REPLICA OF 'source_db';
3. Monitoring Aurora Performance:
aws cloudwatch get-metric-statistics --namespace AWS/RDS --metric-name CPUUtilization \ --dimensions Name=DBInstanceIdentifier,Value=<your-db-instance> \ --start-time 2023-10-01T00:00:00Z --end-time 2023-10-02T00:00:00Z \ --period 3600 --statistics Average
4. Backing Up an Aurora Database:
aws rds create-db-snapshot --db-instance-identifier <your-db-instance> \ --db-snapshot-identifier <snapshot-name>
5. Restoring an Aurora Database from a Snapshot:
aws rds restore-db-instance-from-db-snapshot --db-instance-identifier <new-db-instance> \ --db-snapshot-identifier <snapshot-name>
6. Enabling High Availability in Aurora:
aws rds modify-db-cluster --db-cluster-identifier <your-cluster> \ --enable-http-endpoint --apply-immediately
7. Checking Aurora Cluster Status:
aws rds describe-db-clusters --db-cluster-identifier <your-cluster>
8. Scaling Aurora Read Replicas:
aws rds create-db-instance-read-replica --db-instance-identifier <replica-name> \ --source-db-instance-identifier <source-db-instance>
