13.7.5.34 SHOW SLAVE HOSTS Syntax

SHOW SLAVE HOSTS

Displays a list of replication slaves currently registered with the master.

SHOW SLAVE HOSTS should be executed on a server that acts as a replication master. The statement displays information about servers that are or have been connected as replication slaves, with each row of the result corresponding to one slave server, as shown here:

mysql> SHOW SLAVE HOSTS;
+------------+-----------+------+-----------+
| Server_id  | Host      | Port | Master_id |
+------------+-----------+------+-----------+
|  192168010 | iconnect2 | 3306 | 192168011 |
| 1921680101 | athena    | 3306 | 192168011 |
+------------+-----------+------+-----------+
  • Server_id: The unique server ID of the slave server, as configured in the slave server's option file, or on the command line with --server-id=value.

  • Host: The host name of the slave server as specified on the slave with the --report-host option. This can differ from the machine name as configured in the operating system.

  • User: The slave server user name as, specified on the slave with the --report-user option. Statement output includes this column only if the master server is started with the --show-slave-auth-info option.

  • Password: The slave server password as, specified on the slave with the --report-password option. Statement output includes this column only if the master server is started with the --show-slave-auth-info option.

  • Port: The port on the master to which the slave server is listening, as specified on the slave with the --report-port option.

    In MySQL 5.5.23 and later, a zero in this column means that the slave port (--report-port) was not set. Prior to MySQL 5.5.23, 3306 was used as the default in such cases (Bug #13333431).

  • Master_id: The unique server ID of the master server that the slave server is replicating from. This is the server ID of the server on which SHOW SLAVE HOSTS is executed, so this same value is listed for each row in the result.
