Zato installation on RHEL

Requirements

• RHEL and compatible, v. 8.x
• Root access
• Make sure you have Python 3.8 - RHEL 8.x by default ship with Python 3.6. Ensure that output from the python3 command is Python 3.8. For instance:

  python3
  Python 3.8.8 (default, Aug 11 2021, 06:52:42)
  [GCC 8.5.0 20210514 (Red Hat 8.5.0-3)] on linux
  

• If you have Python 3.6, to change it to 3.8, run these commands as root:

  yum install python38 python38-devel -y
  alternatives --set python3 /usr/bin/python3.8
  

Installation steps

• Log in as root:

su -

yum update -y
