我使用的机器操作系统是centOS8。所以这里使用的指令也是centOS8上的指令（不过也没差别）。
1. 首先要确定时区
确定时区需要执行 tzselect 指令
[root@test tmp]# tzselect
Please identify a location so that time zone rules can be set correctly.
Please select a continent, ocean, "coord", or "TZ".
1) Africa
2) Americas
3) Antarctica
4) Asia
5) Atlantic Ocean
6) Australia
7) Europe
8) Indian Ocean
9) Pacific Ocean
10) coord - I want to use geographical coordinates.
11) TZ - I want to specify the time zone using the Posix TZ format.
#? 4
输入完成指令后提示选择大洲。我这里选了4-亚洲。
然后就是选择 国家->市，确认等操作：
Please select a country whose clocks agree with yours.
1) Afghanistan 18) Israel 35) Palestine
2) Armenia 19) Japan 36) Philippines
3) Azerbaijan 20) Jordan 37) Qatar
4) Bahrain 21) Kazakhstan 38) Russia
5) Bangladesh 22) Korea (North) 39) Saudi Arabia
6) Bhutan 23) Korea (South) 40) Singapore
7) Brunei 24) Kuwait 41) Sri Lanka
8) Cambodia 25) Kyrgyzstan 42) Syria
9) China 26) Laos 43) Taiwan
10) Cyprus 27) Lebanon 44) Tajikistan
11) East Timor 28) Macau 45) Thailand
12) Georgia 29) Malaysia 46) Turkmenistan
13) Hong Kong 30) Mongolia 47) United Arab Emirates
14) India 31) Myanmar (Burma) 48) Uzbekistan
15) Indonesia 32) Nepal 49) Vietnam
16) Iran 33) Oman 50) Yemen
17) Iraq 34) Pakistan
#? 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.
Selected time is now: Sat Mar 14 22:18:16 CST 2020.
Universal Time is now: Sat Mar 14 14:18:16 UTC 2020.
Is the above information OK?
1) Yes
2) No
#? 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:

2. 配置时区
执行完成选择后并不会直接生效，还需要我们做些操作。根据提示，需要将下面的内容添加到 profile 文件中：
TZ='Asia/Shanghai'; export TZ
执行vim指令打开profile文件：
vim /etc/profile
在 profile 文件尾部追加上面的配置信息。然后执行source指令使配置生效。
source /etc/profile
执行 date 查看时间：
[root@test tmp]# date
Sat Mar 14 22:34:56 CST 2020
可以看到和当前时间是一致的。说明配置已经生效。
