Hoe to increase tempdb size

Hello Team

Please help, I am getting the below error message

Server 'XYZ', Procedure 'sp_configure', Line 232:

Can't allocate space for object '#optlevel01000180025269676' in database

'tempdb' because 'default' segment is full/has no free extents. If you ran out

of space in syslogs, dump the transaction log. Otherwise, use ALTER DATABASE to

increase the size of the segment.

(return status = -7)

How to increase tempdb size.

Thanks
