Managing numerous MySQL databases can be daunting. For secure data protection, creating regular backups is crucial. This comprehensive guide will provide step-by-step instructions on how to effortlessly export and import all MySQL databases simultaneously.
Utilizing the mysqldump utility is the preferred method for exporting multiple databases at once. Using the command line, execute the following command:
mysqldump -u root -p --all-databases > alldb.sql
Specify your database username and password, and store the output in the 'alldb.sql' file. Additional options, such as --opt and --skip-lock-tables, can be specified for performance optimization or to avoid table locking issues.
Once the backup is created, the import process is equally straightforward. Run the following command:
mysql -u root -p < alldb.sql
This command will restore all the databases from the backup file into the MySQL server. Ensure that the username and password are correct, and verify the restoration process by checking the databases and data integrity.
