4.6.8.4 Specifying the mysqlbinlog Server ID
When invoked with the --read-from-remote-server
option, mysqlbinlog connects to a MySQL
server, specifies a server ID to identify itself, and requests
binary log files from the server. You can use
mysqlbinlog to request log files from a
server in several ways:
Specify an explicitly named set of files: For each file, mysqlbinlog connects and issues a
Binlog dumpcommand. The server sends the file and disconnects. There is one connection per file.Specify the beginning file and
--to-last-log: mysqlbinlog connects and issues aBinlog dumpcommand for all files. The server sends all files and disconnects.Specify the beginning file and
--stop-never(which implies--to-last-log): mysqlbinlog connects and issues aBinlog dumpcommand for all files. The server sends all files, but does not disconnect after sending the last one.
With
--read-from-remote-server
only, mysqlbinlog connects using a server ID
of 0, which tells the server to disconnect after sending the
last requested log file.
With
--read-from-remote-server
and --stop-never,
mysqlbinlog connects using a nonzero server
ID, so the server does not disconnect after sending the last log
file. The server ID is 1 by default, but this can be changed
with --connection-server-id.
Thus, for the first two ways of requesting files, the server
disconnects because mysqlbinlog specifies a
server ID of 0. It does not disconnect if
--stop-never is given
because mysqlbinlog specifies a nonzero
server ID.
