How to remove bin logs and turn it off

If your mysql eats enormous amount of space, check if binary logging is on

Check if binlog creating is on

show variables like 'log_bin';

If it is on it will create lots of bin log files on mysql/data folder.

If you have only simple mysql database without master / slaves / replication stuff, you have opportunity to get free space and block creating bin logs in the future.

Purge existing bin logs

PURGE BINARY LOGS TO 'mysql-bin.010';
PURGE BINARY LOGS BEFORE '2019-04-02 22:46:26';

Block creating binlogs

// /etc/mysql/my.cnf
[mysqld]
disable_log_bin

and restart mysql server
