Extract and Import Database to Remote Server


This guide will demonstrate how to extract and import database to remote server. 

Prerequisites

This guide allows any user with SSH access to import a database backup to a remote server and assign to a user.

Guide to Extract and Import Database to Remote Server

To extract and import database backup from server containing the backup to a remote server, follow these steps:

  1. Login to the server containing the database backup (in this example, we will use database_wp.sql.gz).
  2. Navigate to the directory containing the backup file. If the file is located at /backups/username/dbs/database_wp.sql.gz then you would enter the /backups/username/dbs directory:
    cd /backups/username/dbs
  3. Now, run the following command to unzip the database and transfer the .sql file to the destination server:
    gunzip -c database_wp.sql.gz | ssh username@server.domain.tld mysql --user=database_wp --password=db_password database_wp

Note: the destination server would need to have the correct user and password already existing.

You can use the following commands to create the user on the destination server:

CREATE USER 'database_wp'@'localhost' IDENTIFIED BY 'db_password';

GRANT ALL PRIVILEGES ON * . * TO 'database_wp'@'localhost';

FLUSH PRIVILEGES;

CREATE DATABASE database_wp;

Conclusion

That's it. You've now exported the database.
