Huge 0.000001 and 0.000002 files and so on, in mysql data folder
These are your binary logs.
For some reason, your config file lists:

log-bin = 0


Did you mean by that to disable binary logs? Well, instead, you've simply named them as "0". Which is why you get all these files: 0.000001, 0.00002 etc.

If you want binary logging, better name them properly:

log-bin = mysql-bin


(this will make files named mysql-bin.000001, mysql-bin.000002 etc)

If you don't want binary logging, just comment the line:

#log-bin = mysql-bin


Typically, binary logs are desired: they are essential if you want to set up replication, or do logical point-in-time recovery.

If you do decide to disable them, and are convinced you do not need them, then you can also purge them:

mysql&gt; PURGE MASTER LOGS TO '0.000025';


will delete all logs up to and excluding given log file.
