At this stage, a minimal Redhat installation must be running and ready for specifig configuration

Edit configuration files to complete system setup

Hostname

Set the hostname in the files or use hostnamectl:

/etc/hostname

Example:

rhel-host.skoor.local

Hostfile - should contain at least the own hostname, domain and IP address:

/etc/hosts

Example:

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.1.0.84   rhel-host.skoor.local rhel-host

DNS configuration

/etc/resolv.conf

Example:

domain skoor.local
search skoor.local skoor.com
nameserver 10.1.0.22

NTP - Network Time Protocol - define reachable ntp server(s)

NTP is important, especially when SKOOR systems are configured with external collectors. Make sure that it is activated on all involved servers

From Red Hat version 7 onwards, chrony may be used instead of ntpd. Please refer to the chrony documentation to configure it

Configuration for ntpd:

/etc/ntp.conf

Example:

server 10.1.0.1

Enable ntp at startup and start it (Red Hat 7):

# systemctl enable ntpd 
# systemctl start ntpd
