Connect to MySQL
For Multi-Tier Solutions without Amazon RDS, you can connect to the database from the same computer where it is installed with the mysql client tool.
$ mysql -u root -p
For Multi-Tier Solutions with Amazon RDS, use the command below instead. Replace the HOSTNAME placeholder with the actual hostname for the Amazon RDS instance (more information).
$ mysql -u root -h HOSTNAME -p
You will be prompted to enter the root user password. This is the same password entered during the server deployment process.
