About DataStax installer

The DataStax installer installs DataStax Enterprise and DataStax Agent. It does not install OpsCenter. If you select Developer Related Tools during installation, DataStax Studio is installed.

The installer sets some but not all cassandra.yaml parameters. It does not set dse.yaml properties. Set the remaining parameters in the following ways:

Manually after installation.
To specify pre-configured cassandra.yaml and dse.yaml files, use the unattended install with either command line or property file.

After accepting the License Agreement, select the type of installation:

Service Setup
- No Services: This installation sets up the server as a standalone process.
- Services and Utilities: This installation sets up the server as a service. It sets up a property (.plist) file to start the service on login.
  - Simple: Installs DataStax Enterprise using the default path names and options:
  - Advanced: Allows you to configure path names and options:
    
    User Setup
    
    Ring Options
    
    Directory Locations
    
    Ports
Set the installation directory.

Set up the node:

Node setup
Default Interface	Network interface for the DataStax Enterprise server.Single node clusters: use 127.0.0.0.
Cluster Name	Name of the cluster. You must use the same cluster name for each node in the cluster.
Seeds	All nodes use the seed node list for finding each other and learning the topology of the ring. Single node clusters: Set to empty. Multiple node clusters: List of seed nodes. (Do not make all nodes seed nodes.) Additional information: Internode communications (gossip) Initializing a single datacenter per workload type Initializing multiple datacenters per workload type
Install developer related tools	Includes the following: Javadocs DataStax Enterprise demos DataStax Studio DSE Graph Loader

If an installation of DataStax Enterprise already exists, the installer displays upgrade information and installs DSE in the previous installation location

Before upgrading an existing cluster, see the DataStax Upgrade Guide.

The important files to review for upgrade are dse.yaml, cassandra.yaml, and for service installs/etc/default/dse.

If dse.in.sh or cassandra.in.sh have been modified, make modifications to the cassandra-env.sh or the dse-env.sh instead. Changing these files is not recommended.

Set the ring options:

Ring options
Enable Virtual Nodes (vnodes)	Enable or disable Virtual nodes.
Number of tokens	Token recommendations for vnodes: Transactional nodes: `128` Analytical nodes (Spark): `128` Search nodes: `8` DSE Graph: `128`. When used with DSE Search: `8`
Listen Address	`cassandra.yaml`: `listen_address`
RPC Address	`cassandra.yaml`: `rpc_address`

Set up the node type:

DSE setup
DSE Analytics	DSE Analytics includes integration with Apache Spark™.
DSE Search	DSE Search includes integration with Apache Solr™.
DSE Graph	DSE Graph is a graph database for managing, analyzing, and searching highly-connected data.
DSE Advanced Replication	DSE Advanced Replication supports configurable distributed data replication from source clusters to destination clusters bi-directionally that can experience sporadic connectivity.

Set up the miscellaneous options:

Misc options
Start services	Yes starts all services when the installation is complete. No, select when additional configuration is needed after installation.
OpsCenter Address	Optional. The server name or IP address for OpsCenter

If performing a Simple installation, go to 16.

The following steps are displayed when Advanced is selected in 4.

Change the default directory locations (Advanced Installations only):

Directory locations
Data Directory	`cassandra.yaml` `data_file_directories`
Commitlog Directory	`cassandra.yaml`: `commitlog_directory`
Saved Caches Directory	`cassandra.yaml`: `saved_caches_directory`
Hints Directory	`cassandra.yaml`: `hints_directory`
Logs Directory	Log data for the database, Spark, and Tomcat. See the default file locations for Installer-Services and package installations or Installer-No Services and tarball installations.

Change the default ports (Advanced Installations only):

Ports

Storage Port

cassandra.yaml: storage_port

SSL Storage Port

cassandra.yaml: ssl_storage_port

RPC Port

cassandra.yaml: rpc_port
In System Configuration, review any warnings about potential issues.
After the installation completes, review the installation logs to verify the installation.

If you have closed the logs, see Services or No-Services installer locations.

DataStax Enterprise is ready for additional configuration.
Optional: Single-node cluster installations only:
1. If DataStax Enterprise is not running, start it from the installation directory:
  $ bin/dse cassandra
  where the installation directory is either:
  - /usr/share/dse
  - the directory where you installed DataStax Enterprise.

Ports
Storage Port	`cassandra.yaml`: `storage_port`
SSL Storage Port	`cassandra.yaml`: `ssl_storage_port`
RPC Port	`cassandra.yaml`: `rpc_port`

For other start options, see Starting DataStax Enterprise as a stand-alone process.

Verify that DataStax Enterprise is running from the installation directory:

$ bin/nodetool status
