Export Database Using SSH

Introduction to SSH Database Export

Exporting a database using SSH is a reliable method for handling large databases or when encountering issues with phpMyAdmin. This tutorial will guide you through the process using the mysqldump command.

Prerequisites for Exporting a Database

Before starting, ensure you have SSH access to your hosting environment and know your database username and password. Changing the database password is possible if you have forgotten it.

Using the mysqldump Command

To export your database via SSH, the mysqldump command is used. This command requires the database username and database name as arguments, and you will be prompted to enter the password during the process.

Specifying the Export File

With the mysqldump command, use the -u flag to specify the database username. Direct the output to a file by using the greater than sign (>) followed by your file name, typically file.sql.

Understanding Export Time

The time it takes to export a database using SSH can vary. Factors include the database's size and the server's performance. Patience may be necessary for larger databases.

Starting the Export Process

Begin the export by entering the mysqldump command followed by the necessary flags and arguments. You will be prompted for the database password to initiate the export to the specified file.

Frequently Asked Questions
