+# AWS RDS Masterclass Commands
+
+## Databases on EC2 Instance - Demo
+### Begin Configuration :
+```bash
+yum -y install mariadb-server wget
+systemctl enable mariadb
+systemctl start mariadb
+yum -y update
+```
+### Set Environmental Variables
+```bash
+DBName=ec2db
+DBPassword=admin123456
+DBRootPassword=admin123456
+DBUser=ec2dbuser
+```
+### Database Setup on EC2 Instance:
+```bash
+echo "CREATE DATABASE ${DBName};" >> /tmp/db.setup
+echo "CREATE USER '${DBUser}' IDENTIFIED BY '${DBPassword}';" >> /tmp/db.setup
+echo "GRANT ALL PRIVILEGES ON *.* TO '${DBUser}'@'%';" >> /tmp/db.setup
+echo "FLUSH PRIVILEGES;" >> /tmp/db.setup
+mysqladmin -u root password "${DBRootPassword}"
+mysql -u root --password="${DBRootPassword}" < /tmp/db.setup
+rm /tmp/db.setup
+```
+### Adding some dummy data to the Database inside EC2 Instance:
+```bash
+USE ec2db;
+CREATE TABLE table1 (id INT, name VARCHAR(45));
+INSERT INTO table1 VALUES(1, 'Virat'), (2, 'Sachin'), (3, 'Dhoni'), (4, 'ABD');
+SELECT * FROM table1;
+```
+### Migration of Database in EC2 Instance to RDS Database:
+```bash
+mysqldump -u root -p ec2db > ec2db.sql
+mysql -h <replace-rds-end-point-here> -P 3306 -u rdsuser -p
+CREATE DATABASE rdsdb;
+mysql -h <replace-rds-end-point-here> -P 3306 -u rdsuser -p rdsdb < ec2db.sql
+USE rdsdb
+SELECT * FROM table1;
+```
