First, the relevant export statement
1, export the database (with drop table structure, the table data):
mysqldump -uroot -p --databases database table name --tables Table 1 name 2> E: db1.sql
--tables Table 2 is an optional field.
2, with the proviso export database table data (with the drop table structure, data table):

For each table, with / * 40000 ALTER TABLE tbl_name DISABLE KEYS * /;! And / * 40000 ALTER TABLE tbl_name ENABLE KEYS * /;! Statement references INSERT statement. This will import more quickly out of the dump file because it is inserted in the indexes are created after all rows. This option is only for MyISAM tables turned on by default.
mysqldump -uroot -p --all-databases
24, - dump-slave binlog This option will be master of the location and file name is appended to the file export data (show slave status).
When set to 1, it will be in CHANGE MASTER command output to the data file; set to 2, will add comments before change. This option will open --lock-all-tables, unless --single-transaction is specified. This option will automatically turn off --lock-tables option. The default value is 0.
Databases -uroot--p---all the mysqldump --dump-Slave. 1 =
the mysqldump --all -uroot--p-Slave---dump Databases = 2
25, - master-data this option binlog location and file name of the current server is added to the output file (show master status).
If it is 1, the output will CHANGE MASTER command; if the former is to add annotations 2, the output command CHANGE MASTER. This option will open --lock-all-tables option, unless --single-transaction also is specified (in this case, a global read lock is acquired for a short time at the beginning of the export; other content refer to the following --single -transaction option). This option automatically turns off --lock-tables option.

Note: If you export multiple databases once (using the option --databases or --all-databases), will refresh the logs one by one database. In addition to using --lock-all-tables or --master-data. In this case, the log will be refreshed once, so the corresponding table is locked at the same time. Therefore, if you plan to export both logs and refresh should use --lock-all-tables or --master-data and --flush-logs.
mysqldump -uroot -p --all-databases --flush- logs
