set time esxi تنظیم ساعت سرورها-ESXI- تنظیم دستی

set time esxi تنظیم ساعت سرورها-ESXI

ssh روی esx فعال کرده

و دستور زیر را در محیط cli بزنید

تنظیم دستی همون دکمه رادیویی هست که زمان داخل کادر را نشان می دهد و اگر ntp فعال نباشد ماشین به صورت دیفالت زمان را از این کادر می گیرد

UTC نیست

سرویس PTP غیر فعال باشد مهم نیست

برای فعال سازی سرویس NTP

اگر ساعت قبلش به صورت دستی هم تنظیم کردی این دستورات بزنی دیگر نیاز به ریبوت سرور هم نیست

esxcli system ntp set –server=192.16.20.1

esxcli system ntp set –enabled=yes
ntpq -p
chkconfig ntpd
esxcli network firewall ruleset rule list | grep ntp
esxcli system stats installtime get

hardware یعنی زمان تنظیم دستی و این مهم هست
M mounth
esxcli hardware clock set -d 12 -H 04 -m 57 -M 12 -y 2024 -s 45
esxcli system time set -d 12 -H 04 -m 57 -M 12 -y 2024 -s 45

esxcli hardware clock get
esxcli system time get

_______________________________

Time Synchronization is disabled by default but if you like to enable it, configure like follows. For ESXi time settings, it’s impossible to change timezone setting on ESXi, timezone is set to UTC. So time stamps of files or log recordes are stored with UTC time. Therefore, you need to see time stamps on the system with remembering they are UTC time.
[1]	Configure Time Synchronization Settings.
