Adds a server to the cluster
couchbase-cli server-add [--cluster <url>] [--username <username>]
[--password <password>] [--server-add <servers>] [--group-name <name>]
[--server-add-username <username>] [--server-add-password <password>]
[--services <services>] [--index-storage-setting <mode>]
The server-add subcommand is used to add one or more servers to a cluster. Before adding a server it is important to decide which services the server will be running and whether or not the server should be a part of a specific group. Keep in mind that if the index service is being added on one of the servers and the cluster is not currently running the index service that you also need to set the index storage mode. This can be done with the --index-storage-setting option.
- --server-add <servers>
-
A comma separated list of servers to add to the cluster. The each server in the list should be identified by a hostname or IP address. If a scheme is not provided it will use
https:// - --server-add-username <username>
-
Adding a server to the cluster can only be done by a user with the appropriate credentials. This flag specifies the username for a user who has the ability to modify the cluster topology on the server being added.
- --server-add-password <password>
-
Adding a server to the cluster can only be done by a user with the appropriate credentials. This flag specifies the password for a user who has the ability to modify the cluster topology on the server being added.
- --group-name <name>
-
The name of the group to add the server to. If this option is not specified then the server is added to the default group.
- --services <services>
-
A comma separated list of services that this server should be running. Accepted services are "data", "index", "query", "fts", "eventing", "analytics" and "backup".
- --index-storage-setting <mode>
-
Specifies the index storage mode. This parameter must be set if the servers being added contain the index service and this is the first time the index service is being added in this cluster. You may specify "default" for disk based indexes or
memoptfor memory optimized indexes.
If we want to add a server at 192.168.1.6:8091 with the index, data and query service on it then we would run the command below.
$ couchbase-cli server-add -c 192.168.1.5:8091 --username Administrator \ --password password --server-add http://192.168.1.6:8091 \ --server-add-username Administrator --server-add-password password --services data,index,query
Note that in the example above we set the username and password of the server being added to the same value as the username and password of the servers already in the cluster. This is done if the server being added has not already been initialized. If the server being added has been initialized then you will need to specify an appropriate username and password for the server being added.
Now lets add two server to the East group with data, index,and full-text services. In this example we will also assume that the index is being added for the first time so we need to specify the index storage mode. If we want to index storage mode to be memory optimized then we would run the following command.
$ couchbase-cli server-add -c 192.168.1.5:8091 --username Administrator \ --password password --server-readd http://192.168.1.6:8091,http://192.168.1.7:8091 \ --server-username Administrator --server-password password --services data,fts --group-name --index-storage-setting memopt
