1、前提
由于公司有在印尼的项目，所以购买了阿里云在新加坡机房的服务器（在印尼还没有），印尼当地使用的是东七区的时间，所以领导要求修改阿里云ECS系统的时区。
2、动手
修改阿里云ECS服务器系统的时区有两种方法：
1、通过tzselect修改：
[root@iZt4nbfbkurxm1k2bmdsqvZ /]# 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 #? 15 Please select one of the following time zone regions. 1) Java, Sumatra 2) Borneo (west, central) 3) Borneo (east, south); Sulawesi/Celebes, Bali, Nusa Tengarra; Timor (west) 4) New Guinea (West Papua / Irian Jaya); Malukus/Moluccas #? 1 The following information has been given: Indonesia Java, Sumatra Therefore TZ='Asia/Jakarta' will be used. Local time is now: Wed Sep 27 12:58:33 WIB 2017. Universal Time is now: Wed Sep 27 05:58:33 UTC 2017. Is the above information OK? 1) Yes 2) No #? 1 You can make this change permanent for yourself by appending the line TZ='Asia/Jakarta'; 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/Jakarta [root@iZt4nbfbkurxm1k2bmdsqvZ /]#

2、通过修改配置文件：
1.vi /etc/sysconfig/clock 2.ZONE=Asia/Jakarta（查/usr/share/zoneinfo下面的文件） 3.rm /etc/localtime 4.ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

然后停止ntp服务，过一段时间之后启动ntp服务即可。
[root@iZt4nbfbkurxm1k2bmdsqvZ /]# date Wed Sep 27 13:00:57 WIB 2017 [root@iZt4nbfbkurxm1k2bmdsqvZ /]# date -R Wed, 27 Sep 2017 13:01:06 +0700 [root@iZt4nbfbkurxm1k2bmdsqvZ /]#
