Operating system

  1. ADS supports only x86_64 architecture and the following operating systems:

    • Centos 7.6.1810;

    • RHEL 7.6;

    • AltLinux sp 8.4 — available only for the Enterprise version;

    • Astra Linux 1.7 "Орел" SE with Axiom JDK — available only for the Enterprise version;

    • RedOS 7.3.2 — available only for the Enterprise version.

  2. You need to prepare all dependent repositories together with the chosen operating system.

  3. All machines in the cluster must have access to the official repositories (or create a local mirror):

  4. In the case of online installation, you must provide access to the repositories listed on the Configuration tab in the ADS cluster menu in the ADCM UI. The Configuration tab is described in Configure a cluster.

  5. In the case of offline installation, you must provide access to the host where the Enterprise Tools cluster is deployed. Installing an Enterprise Tools cluster is described in the section Install Enterprise Tools cluster.

Preinstalled software

  1. NTP must be preconfigured on servers.

  2. Access must be given to the root user or another user with sudo rights.

Installation features

  1. The installation process modifies files that should not be controlled by the configuration management system (if available):

    • system file /etc/hosts;

    • system file /etc/selinux/config;

    • system file /etc/sysctl.conf.

  2. The installation process creates files in /usr/lib/systemd/system/ that should not be controlled by the configuration management system (if available).

  3. Services installed on a cluster should not be controlled by the configuration management system (if available).

SELinux

SELinux must be turned off. The full guide about this operation you can find in Install ADCM.

Firewall

Firewall must be stopped. The full guide about this operation you can find in Install ADCM.

Supported browsers for NiFi

  1. The work of the NiFi service is supported by browsers:

    • Chrome

    • FireFox

    • Edge

    • Safari

  2. UI is supported in the current stable release of that browser and the preceding one. For instance, if the current stable release is 45.X then the officially supported versions will be 45.X and 44.X.

  3. For Safari, which releases major versions much less frequently, supported versions will be the two latest releases.

  4. The supported browser versions are driven by the capabilities the UI employs and the dependencies it uses. UI features are developed and tested against the supported browsers.
