Install the Splunk Data Stream Processor

To install the Splunk Data Stream Processor (DSP), download, extract, and run the installer on each node. You must contact your Splunk representative to access the Splunk Data Stream Processor download page. The Splunk Data Stream Processor is installed from a Gravity package, which builds a Kubernetes cluster that DSP is installed and deployed onto. See the Gravity documentation for more information.

At a glance, the DSP installer does the following things:

Checks that the system is running on a supported OS.
Checks that the system passes pre-installation checks such as meeting the minimum system requirements.
Checks that the system is not already running Docker or other conflicting software.
Checks that the system has the necessary running services and kernel modules.
Installs Docker, Kubernetes, and other software dependencies like SCloud. For more information about SCloud, see Get started with SCloud.
Prepares Kubernetes to run the Splunk Data Stream Processor.
Installs the Splunk Data Stream Processor.
Checks that the Splunk Data Stream Processor is ready for use.

See What's in the installer directory? for information about the files and scripts that the installer tarball contains.

Extract and run the Splunk Data Stream Processor installer

Prerequisites

Prerequisite	Description
Your system meets the minimum hardware and software requirements for DSP.	See Hardware and Software requirements.
The required ports are open.	See Port configuration requirements.
The download link for the Splunk Data Stream Processor.	Contact Splunk Support.
Disable SELinux.	To disable SELinux, run `setenforce 0` on your nodes.
Synchronize your system clocks.	Consult the system documentation for the particular operating system on which you are running the Splunk Data Stream Processor. For most environments, Network Time Protocol (NTP) is the best approach.
You have system administrator (root) permissions.	You need administrator (root) permissions so Kubernetes can leverage system components like iptables and kernel modules. If you do not have root permissions, you can use the `sudo` command.

Steps

Download the Splunk Data Stream Processor installer tarball on each node.
On each node in your cluster, extract the Splunk Data Stream Processor installer from the tarball. In order for the DSP installation to complete, you must have the right number of nodes ready to join to form a cluster. The number of nodes depends on the installation flavor you select in step 4.
```
tar xf <dsp-version>-linux-amd64.tar
```
The DSP installer times out after 5 minutes, so if you don't have these nodes prepared, you need to start the installation process over again.

Do not untar and later run the installer from the /tmp folder.
On one of the nodes that you want to be a master node, navigate to the extracted file.
```
cd <dsp-version>
```

Determine which flavor of DSP you want to install. Each install flavor comes with a different set of profiles that you can assign to your nodes. The number in the install flavor name corresponds to the minimum number of master or control plane nodes that the flavor supports. Installation flavors are fixed at installation-time, therefore, select the flavor that accommodates the largest implementation that you think you'll need.

Flavor	Available number of master nodes	Minimum cluster size	Recommended cluster size	Notes
ha3	3	3	5-14	Recommended for small-sized deployments. With this flavor, there is no node separation between control and data planes, and therefore, the only profiles available for this flavor are master or worker.
hacp5	5	10	15-50	Recommended for medium-sized deployments. When it comes to operating a larger DSP deployment, you should consider how to manage the communication that needs to happen between the components that comprise the deployment. This flavor includes node separation for control and data planes to better manage this communication. See Control plane and data plane node profiles for more information.
hacp9	9	18	50+	Recommended for large-sized deployments. When it comes to operating a larger DSP deployment, you should consider how to manage the communication that needs to happen between the components that comprise the deployment. This flavor includes node separation for control and data planes to better manage this communication. See Control plane and data plane node profiles for more information.

From the extracted file directory, run the DSP install command. You must run this command with the --flavor=<flavor> flag, but the install command supports several optional flags as well. For a list of all available optional flags, see the Install flags section.
```
./install [--optional-flags] --flavor=<flavor>
```
The order of optional flags matter. The --accept-license and the --location flags must be specified first, followed by any other desired flags. For example: ./install --accept-license --location=/opt/splunk/dsp [--other-optional-flags]

After the initial node has connected to the installer, the installer outputs a join command that you need to run on the other nodes in your cluster. Continue to the next section for instructions.

Join nodes to form the cluster and finish the installation

After running the Splunk Data Stream Processor installer, you must join the nodes together to form the cluster. Follow the instructions for your chosen installation flavor.

Install DSP using the ha3 flavor

After initiating the installation process, the installer prints out a command that you must use to join the other nodes to the first master node. The node number corresponds to the minimum number of nodes that must have this role in the cluster. Copy the text after gravity join.
```
Wed Oct  2 23:59:56 UTC Please execute the following join commands on target nodes:
Role    Nodes   Command
----    -----   -------
master  2       gravity join <ip-address-master> --token=<token> --role=master
```
From the working directory of the other nodes that you want to join the cluster, enter one of the following commands.
- To join this node to form the cluster, use this command:
```
./join <ip-address-of-master> --token=<token> --role=master
```
- To join this node to the cluster and change the location where Gravity stores container and state information, use one of the following commands. By default, Gravity uses /var/lib/gravity to store state information and mounts persistent volumes for containers to /var/data. If you do not have enough disk space in /var to support 24 hours of data retention, use this command to override the default path used for storage.
  - If you used --location in the installation step, enter this:
```
./join <ip-address-of-master> --location=<path> --token=<token> --role=master
```
  - If you used --mount=data:/<mount-path>/gravity/pv --state-dir=/<mount-path>/gravity in the installation step, enter this:
```
./join <ip-address-of-master> --mount=data:/<mount-path>/gravity/pv --state-dir=/<mount-path>/gravity --token=<token> --role=master
```

When you have the required three master nodes to form a cluster, the installation continues. The installation process might take up to 45 minutes. Keep this terminal window open. The following shows the output that is displayed when the installation continues.

(Optional) To add additional nodes as workers to your cluster after the installation is complete, enter the following command from the working directory of the node you want to add:
```
./join <ip-address-master> --token=abc –role=worker
```
While you can add additional master nodes with this command beyond the requirements of the flavor you selected, adding master nodes does not improve the high availability guarantees of the cluster, because services are still fixed to the original number of master nodes.

After these steps, Gravity continues with the installation. Once the installation has finished, Gravity outputs the login credentials to access the DSP UI as well as information about what services are now available as shown here:

Configure the Splunk Data Stream Processor UI redirect URL

By default, the Splunk Data Stream Processor uses the IPv4 address of eth0 to derive several properties required by the UI to function properly. In the case that the eth0 network is not directly accessible (for example, it exists inside a private AWS VPC) or is otherwise incorrect, use the configure-ui script to manually define the IP address or host name that can be used to access DSP.

From the master node, enter the following:

DSP_HOST=<ip-address-of-master-node> ./configure-ui

Next, enter the following:
```
./deploy
```
Navigate to the Splunk Data Stream Processor UI to verify your changes.
```
https://<DSP_HOST>:30000/
```
(Optional) DSP exposes four external network ports: 30000 for the DSP UI, 30002 for Authentication and Login, 31000 for the API Services, and 30001 for the Forwarders Service. By default, DSP uses self-signed certificates to connect to these services. To use your own SSL/TLS certificate to connect to these services, see Secure the DSP cluster with SSL/TLS certificates.
On the login page, enter the following:
```
User: dsp-admin
Password: <the dsp-admin password generated from the installer>
```
If you are using the Firefox or Microsoft Edge browsers, you must trust the API certificate separately. Navigate to the host of your DSP instance at port 31000, for example, https://1.2.3.4:31000 and trust the self-signed certificate.

If you are using the Google Chrome browser and encounter a "net::ERR_CERT_INVALID" error with no Proceed Anyway option when you click Advanced, click anywhere on the background then type "thisisunsafe" to trust the certificate.
(Optional) If you need to retrieve the dsp-admin password, enter the following on your master node:
```
./print-login
```

Reference

Control plane and data plane node profiles

For smaller deployments, the ha3 flavor schedules various components of the DSP cluster to a single group of nodes. For clusters that have less traffic, this simpler choice is sufficient.

To scale to medium to large deployments that are capable of ingesting and processing large amounts of data, worker counts and worker resources of pods associated with data ingestion and processing must be increased. When these workers start to consume large amounts of node resources, for example, CPU/RAM/bandwidth resources, it can negatively impact other services that are sharing those resources on the same node. This is commonly known as the "noisy neighbor problem".

In order to alleviate this noisy neighbor problem, DSP provides the hacp5 and hacp9 deployment flavors. These flavors separate DSP services into two planes or groups of nodes:

Control plane: The control plane contains the components that handle the coordination and logistics of the DSP deployment. An example of a control plane service is the service that activates a pipeline when requested by the user.
Data plane: The data plane contains components that handle ingest and processing of data in the DSP deployment. These services see very high traffic and consume lots of resources. While the majority of compute and resource consumption are in the data plane, because DSP has robust data delivery guarantees, the DSP cluster is relatively tolerant of data plane nodes. See data retention policies for more information about the Splunk Data Stream Processor data delivery guarantees.

When you select either the hacp5 or hacp9 installation flavors, you join nodes as either the control plane profile or the data plane profile, resulting in higher performance and reliability of DSP components.

Install flags

The following table lists the flags you can use with the install command and a description of how to use them:

Flag	Description
--accept-license	Automatically accepts the license agreement that is printed upon completion of the installation. The `--accept-license` and `--location` flags must be specified first before any other optional flags. For example: `./install --location=/opt/splunk/dsp --accept-license [--optional-flags] --flavor=ha3`.
--location <path>	Changes the location where Gravity stores containers and state information. The `--location` flag mounts persistent volumes in `data:<path>/data` and stores state information in `<path>/gravity`. This flag is equivalent to using the `--mount=data:<path>/data` and `--state-dir=<path>/gravity` flags. If you use the `--location` flag to change the location where Gravity stores containers and state information, you must use the flag both when installing and joining the nodes. The `--location` and `--accept-license` flags must be specified first before any other optional flags. For example: `./install --location=/opt/splunk/dsp --accept-license [--optional-flags] --flavor=ha3`. By default, Gravity mounts persistent volumes for containers to `/var/data` and stores state information at `/var/lib/gravity`. If you do not have enough disk space in `/var` to support 24 hours of data retention or you want to change from the default location for containers and state for other reasons, use this command to override the default path used for storage. This command will put both the state and persistent volumes in subdirectories under directory `<path>`. To configure separate directories for mounting persistent volumes for containers and storing state, use the `--mount` and `--state-dir` flags instead. If you use `--location` to install DSP on another drive or partition, you must add a symlink from your intended install location to `/var/data`. For example, if you want to use `--location /data`, then add the symlink `ln -s /data /var/data`. See The following pre-flight checks failed: XXGB available space left on /var/data, minimum of 175GB is required in Troubleshooting for more information.
--cluster <cluster_name>	Gives the DSP cluster a name. If you do not specify a cluster name, DSP automatically generates one for you. This is used by the Splunk App for DSP.
--token <token>	A secure token that prevents rogue nodes from joining the cluster. Your token must be at least six characters long.
--service-uid <numeric>	Specifies the Service User ID. For information about how this is used, see Service User in the Gravity documentation. If not specified, a user named `planet` is created with user id `1000`. The `./join` command does not support the `--service-uid` or `--service-gid` flags, but instead, the worker nodes use whatever value is set on the master node with `./install`.
--service-gid <numeric>	Specifies the Service Group ID. For information about how this is used, see Service User in the Gravity documentation. If not specified, a group named `planet` is created. The `./join` command does not support the `--service-uid` or `--service-gid` flags. Instead, the worker nodes use whatever value is set on the master node with `./install`.
--pod-network-cidr <10.244.0.0/16>	The CIDR range Kubernetes allocates node subnets and pod IPs from. Must be a minimum of `/16` so Kubernetes can allocate `/24` to each node. If not specified, defaults to `10.244.0.0/16`.
--service-cidr <10.100.0.0/16>	The CIDR range Kubernetes allocates service IPs from. If not specified, defaults to `10.100.0.0/16`.
--mount=data:<mount-path> --state-dir=<state-path>	Changes the location where Gravity stores containers and state information. Replace `<mount-path>` and `<state-path>` with the paths that you'd like Gravity to use for storage. For example, if you wanted to mount persistent volumes in `<mount-path>/bar/baz` but store state information in `<state-path>/quux`, then run: `./install --mount=data:<mount-path>/bar/baz --state-dir=<state-path>/quux`. Note that `<mount-path>` could be the same as `<state-path>`, and that `--mount` requires a prefix of `data:`. If you use the `--mount` and `--state-dir` flags to change the location where Gravity stores containers and state information, you must use the flags both when installing and when joining the nodes. By default, Gravity mounts persistent volumes for containers to `/var/data` and uses `/var/lib/gravity` to store state information. If you do not have enough disk space in `/var` to support 24 hours of data retention or you want to change from the default location for other reasons, use these commands to override the default path used for containers and state. These flags can be used to mount persistent volumes for containers and store state information in two separate directories. If you want to change the default locations but you want to use the same parent directory for mounting persistent volumes for containers and storing state, use the `--location` flag instead.
