MySQL™ Cluster Manager 1.3.6 User Manual
start process {[--initial|-i]process_id
| --added}cluster_name
This command starts the MySQL Cluster process having the process
ID process_id
in the cluster named
cluster_name
. The status of the
process to be started, as shown by
show status
--process
, must be added
or
stopped
.
This example demonstrates how to start the process having the
process ID 1
belonging to the cluster
mycluster
:
mcm> start process 1 mycluster;
+------------------------------+
| Command result |
+------------------------------+
| Process started successfully |
+------------------------------+
1 row in set (13.93 sec)
When the --initial
option (short form:
-i
) is used, MySQL Cluster Manager starts a data node process
with the --initial
option, causing
the data node to rebuild its file system.
Invoking this command with the --added
option
rather than with a process ID starts all nodes previously added
to the cluster using add
process
, but not yet started.
You can obtain process IDs for all processes in a given cluster
using show status
--process
or list
processes
. These are the same as the node IDs for
these processes as shown in the output of other
mcm client commands such as
get
or in the output of
ndb_mgm -e "show" (see
ndb_mgm — The NDB Cluster Management Client).
You cannot use this command to start a mysqld
process in a cluster that is stopped or otherwise unavailable;
in MySQL Cluster Manager 1.3.0 and later, trying to do so fails with an error.
(Bug #17073352) This includes a cluster created for import where
the import has not yet been completed (see
Section 4.4.1, “The create cluster
Command”, and
Section 3.5, “Importing MySQL Clusters into MySQL Cluster Manager”).
