Re: Rotate regular log file only
Hi Olaf, We use our mysqldump script to rotate the binlogs; it's much safer as it allows MySQL to do the log rotate natively (if you use logrotate, MySQL will complain that either the log doesn't exist when it expects it to, or your slaves will bail out because they didn't know the log was changed. It happened to us recently when we moved the log directory and didn't update the log index.) At 2am our backup system runs the mysqldump script with the extra parameter --flush-logs. This causes MySQL to rotate the log it's using, and as you found out, all slaves respond to the change without an issue. Andy Olaf Stein wrote: Thanks all...

Re: Rotate regular log file only
Nope, we use the expire_logs_days parameter in MySQL's my.cnf (set to expire_logs_days=7 - removes log files that are 7 days old.) mysqldump's flush-logs does indeed begin a new log - that's the idea of it: # ls -l /srv/mysql rw-rw 1 mysql localservice 213 2008-10-16 00:56 sql-m2-bin.17 -rw-rw 1 mysql localservice 213 2008-10-17 00:56 sql-m2-bin.18 -rw-rw 1 mysql localservice 213 2008-10-18 00:56 sql-m2-bin.19 -rw-rw 1 mysql localservice 213 2008-10-19 00:56 sql-m2-bin.20 -rw-rw 1 mysql localservice 213 2008-10-20 00:56 sql-m2-bin.21 -rw-rw 1 mysql localservice 213 2008-10-21 00:56 sql-m2-bin.22 -rw-rw 1 mysql localservice 213 2008-10-22 00:56 sql-m2-bin.23 -rw-rw 1 mysql localservice 213 2008-10-23 00:56 sql-m2-bin.24 -rw-rw 1 mysql localservice 98 2008-10-23 00:56 sql-m2-bin.25 # /usr/local/mysql/bin/mysqldump --single-transaction --flush-logs --master-data=2 --all-databases --user=xxx --password=xxx /tmp/backup_2008-10-23.sql # ls -l /srv/mysql -rw-rw 1 mysql localservice 213 2008-10-17 00:56 sql-m2-bin.18 -rw-rw 1 mysql localservice 213 2008-10-18 00:56 sql-m2-bin.19 -rw-rw 1 mysql localservice 213 2008-10-19 00:56 sql-m2-bin.20 -rw-rw 1 mysql localservice 213 2008-10-20 00:56 sql-m2-bin.21 -rw-rw 1 mysql localservice 213 2008-10-21 00:56 sql-m2-bin.22 -rw-rw 1 mysql localservice 213 2008-10-22 00:56 sql-m2-bin.23 -rw-rw 1 mysql localservice 213 2008-10-23 00:56 sql-m2-bin.24 -rw-rw 1 mysql localservice 213 2008-10-23 19:37 sql-m2-bin.25 -rw-rw 1 mysql localservice 98 2008-10-23 19:37 sql-m2-bin.26 Notice the last write time of sql-m2-bin.25 and the new file sql-m2-bin.26.
