Configuring the Linux operating system for AE Services Software-only installation

About this task

Use the following steps to run Linux operating system configuration before AE Services Software-only installation.

Before you begin

Use root to run the installation steps as follows:

Procedure

  1. In the /etc/sysconfig/network-scripts/ifcfg-ensXXX or /etc/sysconfig/network-scripts/ifcfg-eth0, make sure the ONBOOT file is set to Yes.
  2. Use GRUB Changes to rename network interface to eth0, if the interface is not currently set to eth0.
    1. Type vi /etc/default/grub
    2. Look for the line GRUB_CMDLINE_LINUX and add the following and click Save:
      net.ifnames=0 biosdevname=0
    3. Type grub2-mkconfig -o /boot/grub2/grub.cfg
    4. If you have not specified names for the interface files during the installation, rename as /etc/sysconfig/network-scripts/ifcfg-*
      • mv /etc/sysconfig/network-scripts/ifcfg-ens, then /etc/sysconfig/network-scripts/ifcfg-eth0.

      • Open /etc/sysconfig/network-scripts/ifcfg-eth0 and rename.

      • Update DEVICE and NAME value from esn* to eth0

  3. Disable the firewall by entering the command systemctl disable firewalld
    warningWarning

    The following is a very slow process, and affects system performance when logging is enabled.

  4. Disable journaling for systemd.
    1. systemctl disable systemd-journald.service
    2. systemctl disable systemd-journald.socket
  5. Make sure you see this line SELINUX=disabled in the /etc/selinux/config file.
  6. Edit /etc/hosts and add an entry for your server, for example ipAddress fqdn hostname.
  7. Edit /etc/resolve and nameserver and search entries.
  8. Run hostname <hostname>
  9. Run shutdown -r now
