配置linux系統時區---解決ntp同步完時間不許問題

ntp配置完成後時間仍然不許有下面兩種狀況：

ntp服務端配置完ntp服務器後，查看時間和百度的時間不同按照下面解決

ntp客戶端同步完ntp服務器後，查看客戶端的時間和百度不一致，按照下面解決 

 

一、配置ntp服務器，設置時區同步，請參照ntp篇  https://www.cnblogs.com/effortsing/p/10011459.html

上面操做完後時間仍然沒法同步，須要操做下面才能夠

二、設置vmare虛擬機時區：

 

2.1 設置時區爲上海

ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime 設置時區爲上海

 

2.1  而後經過tzselect命令來修改時區

執行tzselect命令 --> 選擇Asia --> 選擇China --> 選擇Beijing — 選擇yes ，
執行完tzselect命令選擇時區後，時區並無更改，將export TZ=Asia/Shanghai   添加到/etc/profile文 件中去，而後退出並從新登錄便可。

sed -i '$a\export TZ=Asia/Shanghai' /etc/profile && source /etc/profile && date

 

下面是執行過程

[root@www ~]# tzselect
Please identify a location so that time zone rules can be set correctly.
Please select a continent or ocean.
1) Africa
2) Americas
3) Antarctica
4) Arctic Ocean
5) Asia
6) Atlantic Ocean
7) Australia
8) Europe
9) Indian Ocean
10) Pacific Ocean
11) none - I want to specify the time zone using the Posix TZ format.
#? 5
Please select a country.
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

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.
Local time is now: Wed Dec 5 13:57:48 CST 2018.
Universal Time is now: Wed Dec 5 05:57:48 UTC 2018.
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:
Asia/Shanghai

 

2.二、配置環境變量

[root@www ~]# sed -i '$a\export TZ=Asia/Shanghai' /etc/profile

[root@www ~]# sed -i '$d' /etc/profile

 

2.三、查看時間已經正常

[root@www ~]# dateWed Dec 5 14:11:49 CST 2018
