MySQL: How to clone a database

Here is a way to create a duplicate of one database, with all its tables and their data, under a new name.

  1. Make a dump of your source database:
    mysqldump -uroot -p my_project -r my_project.sql

    Or, if you only want to dump the database's table structure (schema) without any contents:

    mysqldump -uroot -p my_project -r my_project.sql --no-data
  2. Open up a MySQL shell:
    mysql -uroot -p
  3. From the MySQL shell, create a new database and populate it with the dumped data:
    CREATE DATABASE my_project_copy; USE my_project_copy; SOURCE my_project.sql;
  4. Create a user and give it permissions to the new database:
    CREATE USER new_user IDENTIFIED BY 'some_password'; GRANT ALL ON my_project_copy.* TO 'new_user'@'localhost' IDENTIFIED BY 'some_password'; FLUSH PRIVILEGES;
