mysqldump Export All Databases

Exporting Databases

Use the mysqldump command with the --all-databases option to export all MySQL databases. For instance, mysqldump -u root -p --all-databases > alldb.sql exports all databases to a file called alldb.sql. Include the --skip-lock-tables option if necessary to avoid table locking during the dump, as in mysqldump -u root -p --all-databases --skip-lock-tables > alldb.sql.

Preventing UTF8 Issues

Exporting all databases at once can cause issues with UTF8 character encoding. Use the --result-file option to prevent such issues, like mysqldump -u root -p --all-databases --result-file=dump.sql.

Verbose Output

To monitor the progress of the export, include the --verbose flag in your command: mysqldump -u root -p --all-databases --verbose > alldb.sql.

Importing Databases

To import all databases from a dump file, use the mysql command: mysql -u root -p < alldb.sql. Note that this will overwrite existing MySQL users. Alternatively, you can use the source command within the mysql shell to restore databases from backup.sql.

Post-Export Action

After executing the export command, you will be prompted to enter the password for the MySQL account being used.

Additional Export Options

Other variations of the export command include using the --opt flag for optimization or specifying a different user, such as mysqldump -u john -p --all-databases > backup.sql.

Exporting Multiple Databases from Different Accounts

The mysqldump command can also handle multiple databases from various accounts into one file. However, it does not separate the databases into individual files. To archive multiple dump files, use the tar command with options such as -czf to compress and specify the output file.

Frequently Asked Questions

How do I export all my MySQL databases using mysqldump?

To export all MySQL databases, use the command: mysqldump -u root -p --all-databases > alldb.sql. You'll be prompted to enter the root password after executing the command.

What is the purpose of the --all-databases flag in mysqldump?

The --all-databases flag tells mysqldump to export all databases at once, creating a full backup of your entire database set.

Can mysqldump be used to create a logical backup for large databases?

Yes, mysqldump can create logical backups of any size database, but it is not the fastest or most scalable solution for backing up large amounts of data. Physical backups are more appropriate for large-scale backup and restore.

Is it possible to schedule regular backups with mysqldump?

Yes, mysqldump is suitable for regular scheduling, allowing you to automate the process of creating backups at set intervals.

Can I use mysqldump to move data to a remote server?

Yes, mysqldump is good for moving data to a remote server, as it creates a file that can be easily imported into another MySQL server instance.

Common Use Cases

  Creating a complete backup of all databases for disaster recovery
• 
  Migrating all databases from one server to another
• 
  Setting up a development environment with production data
• 
  Archiving the entire database system for compliance and auditing
