Video to cover the section 'Configure time service clients' for the RHCSA (Red Hat Certified System Administrator). More information on the required learning: http://bit.ly/rhcsa8 Notes from the video: To show the current date and time: date To use date to print out the current date and time in a particular format you can use the date variable for example: date +%d%m%y-%H%M%S This can be used in a script to produce a new log file name everytime the script is run for example: touch logfile-`date +%d%m%y-%H%M%S`.log Will output a log file with the current date and time. To get the current hardware clock time: hwclock To set the system clock to hardware clock: hwclock -s To set the hardware clock to the system clock: hwclock -w The main command for managing the time is timedatectl, to see the current time and timezone information: timedatectl To manually set the date and time: timedatectl set-time 2020-18-03 timedatectl set-time 10:26:00 To set the timezone: timedatectl set-timezone Australia/Melbourne To list all available timezones: timedatectl list-timezones To get the timedatectl to use the Network Time Protocol (NTP): timedatectl set-ntp yes The NTP deamon is no longer used as of RHEL8 so we need to use chrony. To install the application run: dnf install chronyd Then start and enable the service: systemctl start chronyd systemctl enable chronyd To edit the servers list edit the chrony.conf file and add entries starting with “server then IP address” and restart the chronyd service: vi /etc/chrony.conf systemctl restart chronyd To see which servers chronyd is currently syncing with run: chronyc sources #rhcsa #rhel #linux #redhat
