MySQL – Database size

Published on June 6, 2010 18:29 Tags: .

As I know, there are two ways to calculate the MySQL database size:

First one:

1

du -shc /var/lib/mysql/*

Second one:

1

SELECT table_schema ,SUM( data_length + index_length) / 1024 / 1024 "Data Base Size in MB" FROM information_schema.TABLES GROUP BY table_schema;
