Getting Started with Database¶
E2E’s Database is a service that makes it easier to set up, operate, and scale a relational database in the cloud. MyAccount Portal provides you a web-based interface for accessing and managing all your Database resources.
How to Create a Database Cluster in Myaccount Portal¶
This section will show you how to create a database cluster from the Myaccount portal. The tutorial that is mentioned below are the basic steps of getting started with the Relational Database cluster in Myaccount Portal
Login into MyAccount Portal¶
Please Login to Myaccount Portal using your credentials set up at the time of creating and activating the E2E Networks ‘My Account’.
On the top right section of the manage database dashboard, You need to click on the “Create Database” Button which will prompt you to the cluster page where you will be selecting the configuration and entering the details of your database
Database Configuration and Setting¶
After creating the database, You need to select the required configuration and setting for your database which are mentioned below.
- 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.
- Host Details
- 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 Server version: 5.5.5-10.0.17-MariaDB-log MariaDB Server Copyright (c) 2000, 2015, Oracle and/or its affiliates. All rights reserved.

Managing Your Database Node¶
In this section, you can find instructions and details to Manage and Maintain your database.
To manage, Click on Action and Select Manage option for your database Node
Database and Connectivity Details¶
In the database page,at the top section, You can find the details of your database configurations.
To check the connectivity details of your database,Click on connectivity details.
Here you can have two options for your database connectivity.
Use Different Read/Write Port:¶
This option will have different read and write port (3306 and 3307) binded for your database connection
Use Same Read/Write Port:¶
This option will have same port binded for both read and write operation for your database connection
To check the host information, Click on Information tab below to get the host details like IP’s and port details.
Allowed Host This setting control the access of Allowed host that can be able to connect your Database node. If No trusted host selected. Anyone can connect using credentials.
Slave configuration for your database cluster allows you to easily maintain having multiple copies of data by copying it from your master database to a slave database. This can be helpful for many reasons including facilitating a backup for the data,a way to analyze it without using the main database, or simply as a means to scale out.
To create a new read-only node to your cluster, Click on Add New slave button. Once the slave node is configured, you can connect your cluster and verify it using below command.
User and Database Details¶
In this section, You will be able to check User credentials and Software details of your database.
Stopping your Database¶
If you are using your DB Node for temporary testing or for any other daily development activity and want to test out your database by stopping it which will close all the connections in your database. You can perform this action by clicking on Action and selecting stop button.
Resume your Database¶
You can resume your database which was stopped earlier by clicking on Resume button in the Action menu. Resuming your database will retain the same IP and credentials for your database and there will not be any changes at configuration level.
Restart your Database¶
If you are testing out your DB nodes, restarting your database to reset connections or for any troubleshooting purpose, You can restart your database by clicking on Restart button on action menu.
Delete your Database¶
To delete your database, click on delete option. Please note that once you have deleted your database you will not be able to recover your database.
Take Manual Snapshot of Database¶
E2E’s Database creates a snapshot of your database node, backing up the entire DB node and not just individual databases. To create a snapshot of your database, Click on Action and select Manual Snapshot option. A pop up menu will appear prompting you to enter the snapshot name. Enter the snapshot name and click on create snapshot.
The amount of time it takes to create a snapshot varies with the size your databases
Restore Snapshot of Database¶
To restore the database snapshot,click on Action and select Restore Snapshot option.The amount of time it takes to restore a snapshot varies with the size your databases. As soon as the restore is complete your database will be in running state.
After you launch your database node, you can view the monitoring graphs for your node on the Monitoring tab. Each graph is based on one of the different metrics. This information is collected from your node and processes raw data into readable graphs. Monitoring is an important part of maintaining the reliability, availability, and performance of your database
Slow Log queries¶
The slow query log feature in MySQL allows you to log all queries that take longer than a given threshold of execution time. The queries in the slow query log are good candidates to start optimizing and eliminating the bottlenecks.
To configure slow log queries, Click on configure view and select the appropriate time duration to log the queries that will be displayed on the dashboard.
You can set up new alerts by defining trigger parameters as per your use case for your database. The alerting system works by sending automatic response notifications to your defined email list.
