1,安裝ntpdate，同步標準時間app

root@hk-confluence:~# apt-get install ntpdate
Reading package lists... Done
Building dependency tree       
Reading state information... Done
ntpdate is already the newest version.
The following packages were automatically installed and are no longer required:
  linux-image-4.4.0-142-generic linux-image-4.4.0-143-generic
  linux-image-extra-4.4.0-142-generic linux-modules-4.4.0-143-generic
  linux-modules-extra-4.4.0-143-generic linux-modules-extra-4.4.0-144-generic

2，進行時間同步報錯：時間程序正在使用socket

root@hk-confluence:~# ntpdate pool.ntp.org
30 May 02:05:42 ntpdate[3388]: the NTP socket is in use, exiting

# 報不認識的服務
root@hk-confluence:~# service ntpd stop
ntpd: unrecognized service
root@hk-confluence:~# systemctl ntpd stop
systemctl: command not found
root@hk-confluence:~# cat /etc/issue
Ubuntu 14.04.5 LTS \n \l

# 採用殺進程的辦法來關閉程序
root@hk-confluence:~# ps -ef |grep ntp
ntp       2590     1  0 May23 ?        00:00:35 /usr/sbin/ntpd -p /var/run/ntpd.pid -g -c /var/lib/ntp/ntp.conf.dhcp -u 106:111
root      3457  3332  0 02:07 pts/0    00:00:00 grep --color=auto ntp
root@hk-confluence:~# kill -9 2590

# 再次進行時間同步
root@hk-confluence:~# which ntpd
/usr/sbin/ntpd
root@hk-confluence:~# /usr/sbin/ntpdate ntp.api.bz
30 May 02:08:27 ntpdate[3489]: adjust time server 17.253.84.125 offset -0.000032 sec
root@hk-confluence:~# date
Thu May 30 02:08:29 UTC 2019
# 發現時區不對

3，修改時區ide

#? 9
Please select one of the following time zone regions.
1) Beijing Time
2) Xinjiang Time
#? 1

The following information has been given:

    China
    Beijing Time

Therefore TZ='Asia/Shanghai' will be used.
Local time is now:    Thu May 30 10:09:37 CST 2019.
Universal Time is now:    Thu May 30 02:09:37 UTC 2019.
Is the above information OK?
1) Yes
2) No
#? yes
Please enter a number in range.
#? 1

You can make this change permanent for yourself by appending the line
    TZ='Asia/Shanghai'; export TZ
to the file '.profile' in your home directory; then log out and log in again.

Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
Asia/Shanghai

4，保存時區文件，使他生效ui

root@hk-confluence:~# date
Thu May 30 02:09:47 UTC 2019
root@hk-confluence:~# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
root@hk-confluence:~# date
Thu May 30 10:12:03 CST 2019
root@hk-confluence:~#
