This utility exports MySQL data and table structures.
Typically, you use it to make backups of databases or to copy databases
from one server to another. You can run it on an active server. For
consistency of data between tables, the tables should be locked (see the
--lock-tables option) or the
mysqld daemon should be shutdown.
There are three syntaxes for this utility. The first method shown makes a backup of all databases for the server. The second method backs up specific databases, named in a space-separated list, including all tables in each database. The third method backs up specific tables of a specific database.
Here is an example using the first method, backing up all databases on the server:
mysqldump --host=russell.dyerhouse.com --user=russell --password \ --lock-tables --all-databases > /tmp/workrequests.sql
Because the backup is being run from a remote server (i.e., not
the localhost), the
option is given with a domain name address for the host. An IP address
could be given instead. Making a backup remotely like this will work
only if the host grants the necessary privileges to user
russell with the host from which
mysqldump is running. The example redirects the
results with a greater-than sign to a text file.
To make a backup of a specific database, use the second syntax for this utility. Enter something like the following ...
