The easiest (although not the fastest) way to move a database between two machines is to run the
following commands on the machine on which the database is located:
shell> mysqladmin -h 'other_hostname' create db_name
shell> mysqldump db_name | mysql -h 'other_hostname' db_name
If you want to copy a database from a remote machine over a slow network, you can use these
commands:
shell> mysqladmin create db_name
shell> mysqldump -h 'other_hostname' --compress db_name | mysql db_name
You can also store the dump in a file, transfer the file to the target machine, and then load the file
into the database there. For example, you can dump a database to a compressed file on the source
machine like this:
shell> mysqldump --quick db_name | gzip > db_name.gz
Transfer the file containing the database contents to the target machine and run these commands
there:
shell> mysqladmin create db_name
shell> gunzip < db_name.gz | mysql db_name
You can also use
