Zato installation on RHEL


  • 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:
    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 -
  • Install helper programs:
yum update -y
