#
? 9 -------这里选9 中国

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

#
? 1 这里选1 北京
The following information has been given: China Beijing Time Therefore TZ
='Asia/Shanghai' will be used. Local time is now: Wed Aug 21 15:46:45 CST 2019. Universal Time is now: Wed Aug 21 07:46:45 UTC 2019. Is the above information OK? 1) Yes 2) No

#
? 1 这里选1 yes确认保存
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 [root@master conf]# date Wed Aug 21 00:47:06 PDT 2019 改到这里此时时区还是PDT,需要修改profile文件 [root@master conf]# vim /etc/profile # time TZ='Asia/Shanghai' export TZ [root@master conf]# source /etc/profile

此时时区已经变为CST

[root@master conf]# date
Wed Aug 21 15:47:46 CST 2019

 

方法2:

修改Linux系统时间EDT改为CST

今天发现一台服务器时间比北京时间慢 12 个小时,使用 date 命令后发现是:

2019年 06月 04日 星期二 21:50:33 EDT

EDT 时间即美国东部时间。这里要改为北京时间即可:

mv /etc/localtime /etc/localtime.bak
ln -s /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime

然后再次 date 查看日期:

2019年 06月 05日 星期三 11:10:58 CST

时间就变成北京时间了.
