1,安装ntpdate，同步标准时间
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，进行时间同步报错：时间程序正在使用

# 报不认识的服务 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 l
# 采用杀进程的办法来关闭程序 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
# 再次进行时间同步
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 # 发现时区不对
3，修改时区

4，保存时区文件，使他生效
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:~#
5，保存到系统底层
