Adding Nodes to Clusters
- reference
Nodes are added to clusters with the POST /controller/addNode
HTTP method and URI.
Syntax
This request adds a server node to the cluster.
One or more services can be specified to run on the added node.
These are kv
(data), index
(index), n1ql
(query), eventing
(eventing), fts
(search), and cbas
(analytics).
If no services are specified, the Data Service is enabled by default.
The node is added with the /controller/addNode
URI.
The administrative username and password must be specified.
curl -u [admin]:[password] [localhost]:8091/controller/addNode -d hostname=[IPaddress] user=[admin] password=[password] services=[kv|index|n1ql|fts|cbas|eventing]
After adding a node to the cluster, remember to rebalance the cluster. See Rebalancing Nodes for details.
Example
The following example adds a server node, 10.2.2.64, to the cluster at 10.2.2.60:8091, establishing the Data, Query, and Index Services on the new node.
The POST method, controller/addNode
, IP address for the new server, and administrative credentials are provided.
Since the POST method is the default, it is not required in the request.
curl -u Administrator:password \ 10.2.2.60:8091/controller/addNode \ -d 'hostname=10.2.2.64&user=Administrator&password=password&services=kv,n1ql,index'
