Permanently setting auto_increment_offset in MySQL

Question

I ran the command as root:

set @@auto_increment_offset = 2;

But the effect cannot be seen from other connections. Why not? It is global.

Answer 1

To set it globally you should add prefix 'GLOBAL' or '@@global.'. For example -

SET @@GLOBAL.auto_increment_offset = 2;

The '@@' is the same as 'SESSION' or '@@session.', it sets session variable.

Using System Variables.
