MySQL 5.7 Reference Manual Including MySQL NDB Cluster 7.5 and NDB Cluster 7.6
On Windows, symbolic links can be used for database directories. This enables you to put a database directory at a different location (for example, on a different disk) by setting up a symbolic link to it. Use of database symlinks on Windows is similar to their use on Unix, although the procedure for setting up the link differs.
Suppose that you want to place the database directory for a
database named mydb
at
D:\data\mydb
. To do this, create a
symbolic link in the MySQL data directory that points to
D:\data\mydb
. However, before creating
the symbolic link, make sure that the
D:\data\mydb
directory exists by creating
it if necessary. If you already have a database directory
named mydb
in the data directory, move it
to D:\data
. Otherwise, the symbolic link
is ineffective. To avoid problems, make sure that the server
is not running when you move the database directory.
On Windows, you can create a symlink using the mklink command. This command requires administrative privileges.
Change location into the data directory:
C:\> cd \path\to\datadir
In the data directory, create a symlink named
mydb
that points to the location of
the database directory:
C:\> mklink /d mydb D:\data\mydb
After this, all tables created in the database
mydb
are created in
D:\data\mydb
.
