save_binary_logs
SAVE_BINARY_LOGS(1p) User Contributed Perl Documentation SAVE_BINARY_LOGS(1p)NAME
save_binary_logs - Concatenating binary or relay logs from the specified file/position to the end of the log. This command is automatically
executed from MHA Manager on failover, and manual execution should not be needed normally.
SYNOPSIS
# Test
$ save_binary_logs --command=test --binlog_dir=/var/lib/mysql --start_file=mysqld-bin.000002
# Saving binary logs
$ save_binary_logs --command=save --binlog_dir=/var/lib/mysql --start_file=mysqld-bin.000002 --start_pos=312
--output_file=/var/tmp/aggregate.binlog
# Saving relay logs
$ save_binary_logs --command=save --start_file=mysqld-relay-bin.000002 --start_pos=312 --relay_log_info=/var/lib/mysql/relay-log.info
--output_file=/var/tmp/aggregate.binlog
save_binary_logs concatenates binary or relay logs from the specified log file/position to the end of the log. This tool is intended to be
invoked from the master failover script(MHA Manager), and manual execution is normally not needed.
DESCRIPTION
Suppose that master is crashed and the latest slave server has received binary logs up to mysqld-bin.000002:312. It is likely that master
has more binary logs. If it is not sent to the slave, slaves will lose all binlogs from mysqld-bin.000002:312. The purpose of the
save_binary_logs is to save binary logs that are not replicated to slaves. If master is reachable through SSH and binary logs are readable,
saving binary logs is possible.
Here is an example:
$ save_binary_logs --command=save --start_file=mysqld-bin.000002 --start_pos=312 --output_file=/var/tmp/aggregate.binlog
Then all binary logs starting from mysqld-bin.000002:312 are concatenated and stored into /var/tmp/aggregate.binlog. If you have binary
logs up to mysqld-bin.000004, the following mysqlbinlog outputs are written.
mysqld-bin.000002:Format Description Event(FDE), plus from 312 to the tail mysqld-bin.000003:from 0 to the tail, excluding FDE
mysqld-bin.000004:from 0 to the tail, excluding FDE
