Install DataStax Enterprise 6.9 on a single node

Use these instructions to install a single instance of DataStax Enterprise (DSE) on Linux-based platforms using a binary tarball. This single node can introduce you to DSE, which includes DSE Security, DataStax Graph, DSE Analytics, and DSE Search.

This installation is intended only for demonstration purposes. For other installations, see Choose an installation method.

Some things to know about installing DataStax Enterprise

These instructions apply to all versions of DSE 6.9. For specific changes, see the DSE 6.9 release notes.
When installed from the binary tarball, DSE runs as a stand-alone process.
When DSE is installed, it creates a cassandra user in the database and runs as this user. Do not use the cassandra user in production. Using the cassandra user is a security risk. See Adding a superuser login.

Prerequisites

Java 11 is required.

If you don’t have a recent version of Java 11, download and install OpenJDK 11.0.x or Oracle JRE SE 11.

Install DSE 6.9 on a single node

Verify that a required version of Java is installed:

java -version

If OpenJDK, the results should look like:

openjdk version "11.0.x" YYYY-MM-DD
OpenJDK Runtime Environment 18.9 (build 11.0.x+xx)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.x+xx, mixed mode)

If Oracle Java, the results should look like:

java version "11.0.x" YYYY-MM-DD LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.x+xx-LTS)
Java HotSpot(TM) 64-Bit Server VM (build 11.0.x+xx-LTS, mixed mode)

Package management tools do not install Oracle Java.

Install the libaio package. For example:
- RHEL platforms:
  sudo yum install libaio
- Debian platforms:
  sudo apt-get install libaio1
- Ubuntu 24.04 and later platforms:
  sudo apt-get install libaio1t64

Click the DSE tarball link to download the tarball file, for example, dse-VERSION-bin.tar.gz.
Extract the tarball file into the directory where you want to install DSE 6.9.
```
sudo tar -xzvf dse-VERSION-bin.tar.gz -C INSTALLATION_DIRECTORY
```
Replace the following: * VERSION: The version of DSE you installed * INSTALLATION_DIRECTORY: The path to the installation directory
Change to the DSE 6.9 directory:
```
cd INSTALLATION_DIRECTORY/dse-VERSION
```
Replace the following: * INSTALLATION_DIRECTORY: The path to the installation directory * VERSION: The version of DSE you installed

Create the default data and logging directories:

/var/lib/cassandra

/var/log/cassandra

sudo mkdir -p /var/lib/cassandra; sudo chown -R $USER:$GROUP /var/lib/cassandra

sudo mkdir -p /var/log/cassandra; sudo chown -R $USER:$GROUP /var/log/cassandra

Start DSE from the installation directory:
```
bin/dse cassandra
```

Verify that DSE is running from the installation directory:

bin/nodetool status
