MySQL 8.0 Reference Manual  /  ...  /  Using Symbolic Links

Pre-General Availability Draft: 2017-06-23

8.12.2 Using Symbolic Links

You can move databases or tables from the database directory to other locations and replace them with symbolic links to the new locations. You might want to do this, for example, to move a database to a file system with more free space or increase the speed of your system by spreading your tables to different disks.

For InnoDB tables, use the DATA DIRECTORY clause on the CREATE TABLE statement instead of symbolic links, as explained in Section 15.7.5, “Creating File-Per-Table Tablespaces Outside the Data Directory”. This new feature is a supported, cross-platform technique.

The recommended way to do this is to symlink entire database directories to a different disk. Symlink MyISAM tables only as a last resort.

To determine the location of your data directory, use this statement:

SHOW VARIABLES LIKE 'datadir';
