如何更改ubuntu服务器的时区
Linux默认情况下使用UTC格式作为标准时间格式,如果在Linux下运行程序,且在程序中指定了与系统不一样的时区的时候,可能会造成时间错误。在Server版中,需要通过tzconfig来修改时区信息了。使用方式(如将时区设置成Asia/Chongqing):
root@nao:~# 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 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) east China - Beijing, Guangdong, Shanghai, etc. 2) Heilongjiang (except Mohe), Jilin 3) central China - Sichuan, Yunnan, Guangxi, Shaanxi, Guizhou, etc. 4) most of Tibet & Xinjiang 5) west Tibet & Xinjiang #? 1 The following information has been given: China east China - Beijing, Guangdong, Shanghai, etc. Therefore TZ=‘Asia/Shanghai‘ will be used. Local time is now: Wed Jul 23 16:07:25 CST 2014. Universal Time is now: Wed Jul 23 08:07:25 UTC 2014. 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
ok,这里我们已经将时区选成了Asia/Shanghai了,但是我们还需要做如下的操作
root@nao:~# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
然后我们执行时间同步命令:
ntpdate 192.168.1.100
然后我们可以查看我们的时间已经调整回来了,如果需要定时同步的话,要在定时任务中加一条同步的定时任务就可以了。
