Oracle RAC 集群搭建 时区调整(六)

这一步需要在所有的三个节点进行调整, Oracle RAC集群对时间的要求比较高,前面已经设置了NTP时间同步服务,如果你不是在虚拟机上而是生产环境上安装则需要手动安装并配置NTP服务。

下面进行时区调整,注意此操作需要在所有节点上进行

[root@e7node2 network-scripts]# 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:	Fri Dec 15 11:50:34 CST 2017.
Universal Time is now:	Fri Dec 15 03:50:34 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/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

最后再确定一下是否调整成功

[root@e7node2 network-scripts]# rm -f  /etc/lcoaltime
[root@e7node2 network-scripts]# ln -s /usr/share/zoneinfo/Asia/Shanghai  /etc/lcoaltime
[root@e7node2 network-scripts]# ls -lrt localtime
ls: cannot access localtime: No such file or directory
[root@e7node2 network-scripts]# cd /dev
[root@e7node2 dev]# ls -lrt localtime
ls: cannot access localtime: No such file or directory
[root@e7node2 dev]# ln -s /usr/share/zoneinfo/Asia/Shanghai  /etc/lcoaltime
ln: failed to create symbolic link ‘/etc/lcoaltime’: File exists
[root@e7node2 dev]# ls ^C
[root@e7node2 dev]# ls ln -s /usr/share/zoneinfo/Asia/Shanghai  /etc/lcoaltime
ls: cannot access ln: No such file or directory
0 /etc/lcoaltime  4 /usr/share/zoneinfo/Asia/Shanghai

庭院深深深几许?杨柳堆烟,帘幕无重数。
玉勒雕鞍游冶处,楼高不见章台路。
雨横风狂三月暮。门掩黄昏,无计留春住。
泪眼问花花不语,乱红飞过秋千去。
