Create DataBase & User setting for your application:

When setting up a clustered database environment, it is important to create a database and user that your application can use to connect to the database servers. This allows you to easily manage and secure access to your databases, while also ensuring that your application can connect to the database seamlessly.

To create a database and user, you need to log in to your hosting provider or database vendor’s client area and navigate to the cluster dashboard. From there, you can create a new database and assign a user to it with specific permissions. You can also specify the load balancer IP address that your application will use to connect to the database servers.

HostinRaja Percono Cluster

You just need to click on Add New Database & User. Then fill up the form shown in the above image by providing the database name, username & password.

So after successfully creating your database, you have to use your public_ip:6033 to connect your database from your application. Those details you will get from. Example image shown below.

HostinRaja Percono Cluster

To change your password, navigate to the user management section of your cluster dashboard and select the user for whom you want to change the password. From there, you can enter a new password and save the changes.

Once you create a database, you can upload your sql file into the master db server using FTP and import your database into your database. Then the database will get update automatically into your slave db servers. So you should always use your master db server for write action.

Setup DataBase Backup:

When setting up a backup plan, you will need to choose the backup interval and the number of backup files to retain. The backup interval determines how frequently backups will be taken, while the number of backup files to retain determines how many backup files will be kept at any given time.

Once you have set up your backup plan and configured the backup interval and number of backup files to retain, the next step is to create a backup script and set it up as a cron job on your master database server. This backup script will run at the specified interval and store the backup files in the designated path on the master server, such as (/backup.db_name/choosen_time_interval/). Example shown in below image.
