Creating Other Connections

Several operators provide access to other third-party or commercial data sources — Solr, Amazon S3, or Salesforce, to name a few. To use those data sources, the operators need a "connection" to connect to the data source and provide access to the data. For the purposes of providing an example, this section describes creating a connection to a Solr search engine.

Note: To use the Solr operators, you must have a Solr server configured with at least one collection. If you have not configured your Solr environment, see theSolr documentation．

Before you can use the Solr connector, you must:

• download and installtheSolr Connectorextension from theRapidMiner Marketplaceonto RapidMiner Studio. Similar to database connections, the extension and the related operator must be installed on every RapidMiner Studio instance that will use the Solr server connection.

• 安装的扩展on RapidMiner Server.

  Note: Be sure to restart RapidMiner Server after installation and then restart RapidMiner Studio (after the server restart).

• configure a connection to your Solr server. Making the connection requires that you know the connection details of your account.

Creating connections from RapidMiner Studio

You must have admin privileges to modify or create connections on RapidMiner Server from RapdiMiner Studio. You canlog in temporarilyto a user's RapidMiner Studio installation to create a connection for them.

1. If you haven't already done so, from RapidMiner Studio,connect to RapidMiner Serverby adding a new or expanding an existing RapidMiner Server repository.

2. From the连接menu, selectManage Connectionsto open theManage Connectionsdialog box.Log in as admin, if required.

   

3. Click onAdd Connectionin the lower left to open theCreate Connectiondialog.

   

4. In the dialog, provide a name for the new connection on RapidMiner Server and setLocationto your RapidMiner Server repository name. From theConnection typepull-down, selectSolr连接and then clickCreate．

5. TheManage Connectionswindow displays the new Solr connection with configuration fields to the right.

   

   Complete the fields:

   1. Specify the URL for your Solr server, in the formhttp://:/solr．
   2. Solr does not include its own authentication. If you have added an authentication mechanism (for example, HTTP authentication) to your Solr server deployment, click theuses authenticationbox to expose an area where you can add login credentials.
   3. Click theTesticon to test the connection to your Solr server.

6. To grant users access to the connection, click on theEditbutton. For more details, see theinstructions for assigning access rights．

7. ClickSave all changesto save your connection configuration.

Creating connections from RapidMiner Server

As an alternative to the above method, you can create the connection directly in RapidMiner Server.

1. From theAdministrationmenu, select连接．

2. Hover over thebutton to see a list of available connections. SelectSolr连接．

   

3. TheNew Solr Connectionwindow opens. Highlight the textNew Solr Connectionand give the connection a more meaningful name.

4. On thePropertiestab, enter the URL for your Solr server. (Selectuses_authenticationif appropriate.) Test the connection and make any adjustments until the connection is confirmed.

   

5. To grant access to users click on thePermissionstab (see theinstructions for assigning access rights, if necessary). ClickSubmitto save the connection.

You can now run processes with operators that use the Solr connection to your Solr server in RapidMiner Server.
