Tip: To upgrade Apache Cassandra to DDAC, see Upgrading Apache Cassandra to DDAC.
Here are some things to know about DDAC:
- The latest version of DDAC is 5.1.18.
- DDAC is based on Apache Cassandra 3.11 and DataStax Enterprise (DSE) 5.1.
- DDAC runs as a stand-alone process.
Warning: When DDAC is installed, it creates a
cassandra
user in the database. Do not use the cassandra
user in production. Failing to do so is a security risk. - A supported platform. DDAC supports the same platforms as listed in the DSE 5.1 (x86_64) column.
- Configure your operating system to use the latest version of Java 8:
- Recommended. The latest build of a Technology Compatibility Kit (TCK) Certified OpenJDK version 8. For example, OpenJDK 8 (1.8.0_151 minimum).Note: Recommendation changed due to the end of public updates for Oracle JRE/JDK 8. See Oracle Java SE Support Roadmap.
- Supported. Oracle Java SE 8 (JRE or JDK) (1.8.0_151 minimum)
- Recommended. The latest build of a Technology Compatibility Kit (TCK) Certified OpenJDK version 8. For example, OpenJDK 8 (1.8.0_151 minimum).
- RedHat-compatible distributions require EPEL (Extra Packages for Enterprise Linux).
- Python 2.7.xhttps://ameblo.jp/tiatjamanav1983/entry-12639470659.html. For older RHEL distributions, see Installing Python 2.7 on older RHEL-based package installations.

- To download the DDAC binaries, contact DataStax Support.Support will provide an up-to-date link to download DDAC.
- Extract the files:For example:
- Define the data and logging directory locations, use one of the following options:
- Default directory locations - No action is required. When the directory locations are excluded or commented out in the cassandra.yaml, Cassandra uses the default locations:
data_file_directories
: installation_location/data/datacommitlog_directory
: installation_location/data/commitlogsaved_caches_directory
: installation_location/data/saved_cacheshints_directory
: installation_location/data/hintscdc_raw_directory
installation_location/data/cdc_raw
- Recommended directory locations - Most production deployments store data and logs in /var/lib/cassandra. To use the recommended location:
- Create and change owners for the /var/lib/cassandra directory:Tip: Ensure that the account that runs
cassandra
has write access to directory for data and logs. The subdirectories are automatically created. - Go the directory containing the cassandra.yaml file:
- Uncomment the following lines in the cassandra.yaml file:Tip: When using a minimal YAML, add the options as shown above.
- Create and change owners for the /var/lib/cassandra directory:
- Custom location - To define custom data and logging directory locations:
- Create the directories for data and logging directories. For example:Tip: Ensure that the account that runs
cassandra
has write access to directory for data and logs. - Go the directory containing the cassandra.yaml file:
- Edit the following lines in the cassandra.yaml file:
- Create the directories for data and logging directories. For example:
- Default directory locations - No action is required. When the directory locations are excluded or commented out in the cassandra.yaml, Cassandra uses the default locations:
- Optional: Single-node cluster installations only.
- Start Cassandra from the installation directory:
- From the installation directory, verify that Cassandra is running:
