Change path for binary logs and scheduling

Question

I want to change the default name of binary log and path. I saw the documentation where it discusses about base_name. However, I just need to confirm how to use it correctly. I want binary logs to be stored on another partition and also want to schedule binary logging to run at regular intervals in a day.

I am using MySQL 5.5.

Answer 1

You should be able to set the binary logs to a new partition by providing the absolute path:

log-bin=/my/other/dir/mysql-bin

You might need to copy the old binary logs to the new directory and update the .index file with the new path information (Do this only when mysql is not running).

Why would you only want to binary log during certain intervals of the day? Doing this could really mess with your ability to restore at any given time.

Answer 2

Step 1: Check current log-bin path and naming format

mysql> show variables like '%log_bin%';

Step 2: Change the log-bin path in my.cnf file as below log_bin = new_path/naming_format

Step 3: Shutdown your mysql server.

Step 4: Move your bin log files from previous location to new location.

Step 5: Star you mysql server.

Step 6 : Check again that, bin-log moved in new location using below command

mysql> show variables like '%log_bin%';

Above I made change log-bin location from "/u01/mysql/mysql/data/" to "/u02/mysql/mysql_binlog/"
