How to bulk clear the expired Binlog above the 128 Group node DB and free up disk space. Go

If 10 units within the DB, you manually ssh in, clean is enough, but hundreds of units, it is necessary to write a script. Approximate idea: In a DB jump connection above, write a script, access slave, remotely get the copy of the master above the Binlog location, and then remote to purge master above the Binlog.

1, establish slave dbserver list slavelist; A slave line.

2, remotely obtain the Binlog location above slave db and the master hostname of slave (perhaps an IP address)

3, get Binlog location and master hostname, and then ssh remotely clean up the Binlog on master

4, Shell forloop operation Step 2 and step 3.

Included with batch for loop script 2:

For S in ' Cat slavelist '; do sh clean_binlog.sh $s; Done

This is a relatively rough plan, there must be shortcomings, my 128 group is a mm combination, so the operation is possible, the structure of different estimates will be changed, here is also related to purge before the Binlog backup and so on (with a dedicated backup machine and backup script).
