Program installation requirements

Requirements for program installation in the Oracle Linux operating system

• A disk image for installation is available on the official Oracle site.
• Make sure that Python version 3.6 or later is installed in the operating system.
• Make sure that the SELinux module is NOT enabled in the operating system. KUMA and the KUMA installer cannot run at the same time while SELinux is enabled.
• Make sure that the pip3 package management system is installed in the operating system.
• Make sure that the following packages are installed in the operating system:
  • netaddr
  • firewalld

  These packages can be installed using the following commands:

  • pip3 install netaddr
  • yum install firewalld

Requirements for program installation in the Astra Linux Special Edition operating system

• Make sure that Python version 3.6 or later is installed in the operating system.
• Make sure that the pip3 package management system is installed in the operating system.
• Make sure that the following packages are installed in the operating system:
  • python3-apt
  • curl
  • libcurl4

  These packages can be installed by running the apt install python3-apt curl libcurl4 command.

• Make sure that the following dependent packages are installed in the operating system:
  • netaddr
  • python3-cffi-backend

  These packages can be installed using the following commands:

  • apt install python3-cffi-backend
  • pip3 install netaddr

  If you are planning to query Oracle databases from KUMA, you must install the libaio1 package.

• You must use the sudo pdpl-user -i 63 <user name> command to assign the required permissions to the user who will be running the program installation.

General installation requirements

• The server where the installer is run cannot have the name localhost or localhost.<domain>. The installer can be run from any folder.
• Before deploying the program, make sure that the servers where you intend to install the components meet the hardware and software requirements.
• KUMA components are addressed using the fully qualified domain name (FQDN) of the host. Before you install the program, you must ensure that the command hostnamectl status returns the true name of the host FQDN in the Static hostname field.
• It is recommended to use Network Time Protocol (NTP) to synchronize time between servers with KUMA services.
• Ext4 is the recommended file system for ClickHouse cluster servers.
