--master-data[=#] This causes the binary log position and filename to be appended to the output. If equal to 1, will print it as a CHANGE MASTER command; if equal to 2, that command will be prefixed with a comment symbol. This option will turn --lock-all-tables on, unless --single-transaction is specified too (in which case a global read lock is only taken a short time at the beginning of the dump - don't forget to read about --single-transaction below). In all cases any action on logs will happen at the exact moment of the dump.Option automatically turns --lock-tables off. -F, --flush-logs Flush logs file in server before starting dump. Note that if you dump many databases at once (using the option --databases= or --all-databases), the logs will be flushed for each database dumped. The exception is when using --lock-all-tables or --master-data: in this case the logs will be flushed only once, corresponding to the moment all tables are locked. So if you want your dump and the log flush to happen at the same exact moment you should use --lock-all-tables or --master-data with --flush-logs
· --all--database,-A转储所有数据库中的所有表。与使用---database选项相同,在命令行中命名所有数据库
--flush-logs,-F开始转储前刷新MySQL服务器日志文件。该选项要求RELOAD权限。请注意如果结合--all--database(或-A)选项使用该选项,根据每个转储的数据库刷新日志。例外情况是当使用--lock-all-tables或--master-data的时候:在这种情况下,日志只刷新一次,在所有 表被锁定后刷新。如果你想要同时转储和刷新日志,应使用--flush-logs连同--lock-all-tables或--master-data。
