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
