Changing Tomcat web server settings

To configure security for DSE Search, change the IP address for client connections to DSE Search using the HTTP and Solr Admin interfaces in the Tomcat web server.xml file.

Where is the cassandra.yaml file?

The location of the cassandra.yaml file depends on the type of installation:

Installation Type Location

Installation Type	Location
Package installations + Installer-Services installations	`/etc/dse/cassandra/cassandra.yaml`
Tarball installations + Installer-No Services installations	`<installation_location>/resources/cassandra/conf/cassandra.yaml`

Package installations + Installer-Services installations

/etc/dse/cassandra/cassandra.yaml

Tarball installations + Installer-No Services installations

<installation_location>/resources/cassandra/conf/cassandra.yaml

Where is the Tomcat server.xml file?

The location of the Tomcat server.xml file depends on the type of installation:

Installation Type Location

Installation Type	Location
Package installations + Installer-Services installations	`/etc/dse/tomcat/conf/server.xml`
Tarball installations + Installer-No Services installations	`<installation_location>/resources/tomcat/conf/server.xml`

Package installations + Installer-Services installations

/etc/dse/tomcat/conf/server.xml

Tarball installations + Installer-No Services installations

<installation_location>/resources/tomcat/conf/server.xml

Procedure

Make configuration changes in the Tomcat server.xml file:

Change the IP address for client connections to DSE Search.

The default IP address that the HTTP and Solr Admin interface uses to access DSE Search is defined with rpc_address in the cassandra.yaml file.

The default rpc_address value localhost enables Tomcat to only listen on the localhost.
To enable Tomcat to listen on all configured interfaces, set rpc_address to 0.0.0.0. To change the IP address for client connections to DSE Search using the HTTP and Solr Admin interfaces, change the client connection in the following ways rpc_address in the cassandra.yaml file or create a Tomcat connector.

Create a Tomcat connector:

In the <Service name="Solr"> section of the server.xml file:

<Connector
    port="PORT"
    protocol="HTTP/1.1"
    address="IP_ADDRESS"
    connectionTimeout="20000"
    redirectPort="8443"
/>

Change the rpc_address

Change rpc_address in the cassandra.yaml file. The rpc_address is read on startup only.

Where is the cassandra.yaml file?

The location of the cassandra.yaml file depends on the type of installation:

Installation Type Location

Installation Type	Location
Package installations + Installer-Services installations	`/etc/dse/cassandra/cassandra.yaml`
Tarball installations + Installer-No Services installations	`<installation_location>/resources/cassandra/conf/cassandra.yaml`

Package installations + Installer-Services installations

/etc/dse/cassandra/cassandra.yaml

Tarball installations + Installer-No Services installations

<installation_location>/resources/cassandra/conf/cassandra.yaml

For advanced users only: In the Tomcat server.xml file, specify a client connection port other than the default port 8983. However, when specifying a non-default connection port, the automatic SSL connection configuration performed by DataStax Enterprise is not done. You must provide the valid connector configuration, including keystore path and password. See the DataStax Support article Configuring the DSE Solr HTTP/HTTPS port.
After making changes, restart the node.
