Installing UMS on Red Hat Enterprise Linux (RHEL) 8

You want to install the UMS on the 64-bit version of Red Hat Enterprise Linux (RHEL) 8. 

The installation of the UMS on RHEL 8 can be done on a plain RHEL 8 system (Server with a GUI).

Before installing the UMS (or UMS HA, see (12.10.100-en) HA Installation), the following steps have to be done:

  1. As root, update the local package database and reboot the server.
    # yum -y update

    The UMS installation will load additional modules if they have not yet been installed: qt5-qtbase

  2. Set the TERM variable as follows, especially if a GUI is installed on the server.

    # export TERM=xterm

  3. Make the /root directory writable.
    By default, the /root directory has no write flag set. As the default installation of UMS HA creates the network configuration archive in this directory, this directory must get the write flag for the root user.

    # sudo chmod u+w /root

  4. Configure the firewall.
    RHEL 8 comes with an activated firewall. For the UMS and UMS HA to work properly, the following ports have to be opened in the active profile (see also (12.10.100-en) IGEL UMS Communication Ports):

    # 8443/tcp 9080/tcp 30001/tcp 30002 tcp 61616/tcp 61616/udp 1528/tcp 6155/udp

    To open these ports, the following commands must be executed:

    # sudo firewall-cmd --zone=public --add-port=8443/tcp --permanent
    # sudo firewall-cmd --zone=public --add-port=9080/tcp --permanent
    # sudo firewall-cmd --zone=public --add-port=30001/tcp --permanent
    # sudo firewall-cmd --zone=public --add-port=30002/tcp --permanent
    # sudo firewall-cmd --zone=public --add-port=61616/tcp --permanent
    # sudo firewall-cmd --zone=public --add-port=61616/udp --permanent
    # sudo firewall-cmd --zone=public --add-port=1528/tcp --permanent
    # sudo firewall-cmd --zone=public --add-port=6155/udp --permanent

  5. Proceed with the UMS installation as described in (12.10.100-en) IGEL UMS Installation under Linux.
