COM_REGISTER_SLAVE

This command is sent by the slave server in order to start MariaDB replication and should be sent before requesting binlog events with COM_BINLOG_DUMP.

The payload is:

Note:

• Slave hostname, slave user, slave password and slave port are usually not set.
  Some slave replication parameters can be used for such settings (report_host, report_port etc).
• Replication rank is not set.
• Master server id is not set as well.

Example of COM_REGISTER_SLAVE

The slave server is configured with:

• server-id=10101
• report-host=slave_n_1
• report-port=23241

 1b 00 00 00 15 75 27 00    00 09 73 6c 61 76 65 5f    .....u'...slave_
 6e 5f 31 00 00 c9 5a 00    00 00 00 00 00 00 00       n_1...Z.......

We can see from the example:

• server_id [4] = 75 27 00 00 => 10101
• hostname_len [1] = 09
• hostname[n] = slave_n_1 (9 bytes)
• username len [1] = 0 (not set)
• password len [1] = 0 (not set)
• slave port [2] = c9 5a => 23241
• rank [4] = 0
• master server id = 0
