System configuration

Basic information

A set of servers or virtual machines is used separately for each component.

Step 1: Configure host names

Configure host names:

sudo hostnamectl set-hostname server1.your_domain --static
sudo hostnamectl set-hostname server2.your_domain --static
sudo hostnamectl set-hostname server3.your_domain --static

Step 2: Configure time synchronization

  1. If your DHCP server doesn’t provide time synchronization information, add IP addresses of NTP servers you want to synchronize the system with. For example:

sudo echo 'NTP=0.pool.ntp.org server 1.pool.ntp.org 2.pool.ntp.org 3.pool.ntp.org' >> /etc/systemd/timesyncd.conf

  1. Restart the timesyncd service:

sudo systemctl restart systemd-timesyncd

  1. To view the current time synchronization status, run the following command:

sudo timedatectl status

  1. You can view detailed information about time synchronization status by running the following command:

sudo timedatectl timesync-status
