Replication and Binary Logging Options and Variables
The user name of the account that the slave thread uses for authentication when it connects to
the master. This account must have the
file takes precedence if it can be read. If the master user name is not set, the name
master.info
is assumed.

Dynamic Variable
The basename for the relay log. The default basename is host_name-relay-bin. The server
writes the file in the data directory unless the basename is given with a leading absolute path name
to specify a different directory. The server creates relay log files in sequence by adding a numeric
suffix to the basename.
Due to the manner in which MySQL parses server options, if you specify this option, you must supply
a value; the default basename is used only if the option is not actually specified. If you use the
[1455] option without specifying a value, unexpected behavior is likely to result; this
relay-log
behavior depends on the other options used, the order in which they are specified, and whether
they are specified on the command line or in an option file. For more information about how MySQL
handles server options, see
If you specify this option, the value specified is also used as the basename for the relay log index file.
You can override this behavior by specifying a different relay log index file basename using the
relay-log-index
You may find the

• Creating relay logs whose names are independent of host names.
• If you need to put the relay logs in some area other than the data directory because your relay logs
tend to be very large and you do not want to decrease
• To increase speed by using load-balancing between disks.
