ps看看ntp的那些东西启动了。

baif

Stop the ntpd then sync the Internet and sync with hwclock. Restart ntpd again.

jordi

Baif:

Tried number of times, didn't work.

HonestQiao:

ps -ef |grep ntpd
ntp      16507     1  0 02:02 ?        00:00:00 ntpd -U ntp -g
root     16541 16464  0 02:03 pts/0    00:00:00 grep ntpd

Tried to downgrade to 4.1. No luck.
