Database Configuration and Setting

After creating the database, You need to select the required configuration and setting for your database which are mentioned below.

../_images/dbs3.jpeg
Database Engine - Database has various database engines available. You need to select the required database engine which you prefer, Below are the list of database engine which we currently support
  • Mariadb - 10.4
  • Mysql 5.6
  • Mysql 5.7
  • Mysql 8.0

Cluster Configuration - Node Cluster configuration comprises varying combinations of CPU, memory, storage and gives you the flexibility to choose the appropriate mix of resources for your database.

Cluster Name - You need to Provide the Cluster name which you want for your cluster. This name will be visible on the Database page

Database Setting - We need to update the database name, user and provide a secure password for our database. You will be using these credentials to log in to the database server.

With strong password authentication, your database controls and authenticates user accounts. If a DB engine has strong password management features, they can enhance security.

Once you have entered the required details, click on create a database. Your database might take a few minutes to Launch. The database node will be in a setting up state until its ready to use and when the status will change to running.

Connecting to your database Cluster

After E2E’s database (DBS) provision your nodes, you can use any standard SQL client application to connect to a database on the DB instance. In this example, you connect to a database on a Maria DB instance using the MySQL command-line tool.

To connect to your database node using MySQL command line

Once your database has been provisioned and its running status, You can get the database connectivity information on the dashboard.

  • Usernames
  • Host Details
  • Port
  • SSL Mode

Enter the following command at a command prompt on your local or client desktop to connect to a Mariadb or mysql database.

mysql -h <host> -P 3306 -u <’username’>  -p <’password’>

After you enter the password for the user, you should see output similar to the following.

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 272
