Press CTRL+C to copyadd hosts {--hosts=|-h }host_list site_name host_list: host[, host[, ...]]
This command adds one or more hosts to an existing management
site. Agents using the same port as the management site must be
running on any hosts added using this command. This command
takes two mandatory arguments: a list of hosts (using the
--hosts
option or its
short form
-h
),
and the name of the site to which the hosts are to be added.
The --hosts
takes a
comma-separated list of one or more hosts to be added to the
site.
For example, the following command adds two hosts named
torsk
and kolja
to
management site mysite
:
Press CTRL+C to copymcm> add hosts --hosts=torsk,kolja mysite; +--------------------------+ | Command result | +--------------------------+ | Hosts added successfully | +--------------------------+ 1 row in set (0.48 sec)
None of the hosts added by this command may already be members
of management site site_name
. Do not
attempt to add again a host that is already a member of the
management site using its secondary (or alternate) IP
address—the mcmd process on the host is
already bound to the IP address that was supplied when the host
was first added, and it cannot be bound again to another IP
address.
This command does not support the
--force
option.Do not use
localhost
in the host list, as MySQL Cluster Manager relies on the operating system for host name resolution, andlocalhost
might be resolved differently on different systems. Use proper host names for the host list or, preferably, use the IP addresses for the hosts instead.When IPv6-enabled Windows systems are used as MySQL NDB Cluster hosts under MySQL Cluster Manager, you must reference these hosts using IPv4 addresses. Otherwise, MySQL Cluster Manager will be unable to connect to the agent processes on those hosts. See Section 6.1, “MySQL Cluster Manager Usage and Design Limitations”.
