Installing SEAL Elastic Stack¶

Overview¶

The installation consists of a server and a client part which you have to install separately.

Server:

The server part includes Elasticsearch and Kibana. You have to install it on the
- Management server.
Client:

The client part contains Filebeat. Depending on your system you have to install it on the following servers:
- PLOSSYS Output Engine server
- PLOSSYS 4 server
- SEAL Operator server
- PLOSSYS Distribution Engine/DPF server

Automatic Configuration¶

SEAL Elastic Stack 8.x provides an automatic configuration, see original documentation, automatic configuration which includes the following security settings:

Minimal Security, see original documentation, Minimal Security
Basic Security, see original documentation, Basic Security.

These include the following actions:

Generating Self-signed Certificates

The automatic configuration
- creates self-signed certificates for Elasticsearch,
- adds their names in the elasticsearch.yml configuration file, and
- stores the certificates in the newly created certs subdirectory.
For details on Certificate files, see Self-signed Certificates.
Activating the Minimal Security

The Minimal Security of Elastic Stack will be activated.

A password for the elastic superuser of Elasticsearch will be generated automatically.

Caution - only on the command line

The password is created by the install.sh or install.ps1 installation script during the installation of SEAL Elastic Stack and printed on the command line.

Make sure, you remember it and keep it safe.

For details on resetting the elastic superuser password, see Resetting Passwords.
Creating and using an enrollment token to configure Kibana

The automatic configuration creates and uses an enrollment token for configuring Kibana. For this, the kibana.yml configuration file is enhanced accordingly.

Management Server¶

Hint - disc Space

Make sure that you have enough disk space available on the installation device. If the amount of free space is less than about 10 % of the device's total capacity, Elasticsearch will lock the created indices and Kibana will not start properly.
