Lab 015: Linux TimeZones Setting

Requirements

During the daily standup, it was pointed out that the timezone across Nautilus Application Servers in Stratos Datacenter doesn't match with that of the local datacenter's timezone, which is Pacific/Saipan.

Correct the mismatch.

Note

This lab focuses on Linux Timezones configuration and management.

Prerequisites

• SSH access to the target server with root or sudo privileges.
• Required utilities and packages available.

Steps

Login to the App server 1 and switch to root. For the server credentials, check out the Project Nautilus documentation.

sshpass -p  '*****' ssh -o StrictHostKeyChecking=no tony@172.16.238.10
sudo su -
*****  

[root@stapp01 ~]# timedatectl  
               Local time: Wed 2023-07-26 17:56:55 UTC
           Universal time: Wed 2023-07-26 17:56:55 UTC
                 RTC time: n/a
                Time zone: Etc/UTC (UTC, +0000)
System clock synchronized: yes
              NTP service: n/a
          RTC in local TZ: no

Search for the timezone.

[root@stapp01 ~]# timedatectl list-timezones | grep -i pacific | grep -i saipan
Pacific/Saipan

Fix the timezone.

[root@stapp01 ~]# timedatectl set-timezone Pacific/Saipan
[root@stapp01 ~]# timedatectl 
               Local time: Thu 2023-07-27 03:59:17 ChST
           Universal time: Wed 2023-07-26 17:59:17 UTC
                 RTC time: n/a
                Time zone: Pacific/Saipan (ChST, +1000)
System clock synchronized: yes
              NTP service: n/a
          RTC in local TZ: no

Repeat same steps on App server 2 and 3.
