centos 6.5 查看时区和设置时区

 centos6.x 和centos7.x在时区方面有点差距,本文是针对centos6.x进行介绍。

其实在我的一个博文里,在安装系统的时候就可以进行时区的设置,本文介绍的是用命令进行时区查看和设置。

使用date命令查看时区

 

[root@ltt1 ~]# date -R
Thu, 28 Sep 2017 00:31:54 +0800

 

我们国家的东八区(+0800)

查看clock系统配置文件

 

[root@ltt1 ~]# cat /etc/sysconfig/clock 
ZONE="Asia/Shanghai"

 

我的系统设置的时区为Asia/Shanghai,也就是我们国家的东八区(+0800)。

下面介绍设置时区的一种方式。

使用tzselect设置时区


[root@ltt1 sysconfig]# 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) 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:    Thu Sep 28 00:10:57 CST 2017.
Universal Time is now:    Wed Sep 27 16:10:57 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

根据提示一步一步选择就可以。

注意:上面最后的几行的说明,大概意思是说,tzselect命令只是输出一个标准的TZ写法,并不生效,你还需要将这个TZ放到你的home目录下的.profile文件里

如:TZ='Asia/Shanghai'; export TZ,同时还有注销再重新登录系统,才可设置永久生效。

下面亲测进行检验一下

我当前时区和时间

[root@ltt1 ~]# date -R;cat /etc/sysconfig/clock 
Thu, 28 Sep 2017 00:46:39 +0800
ZONE="Asia/Shanghai"

tzselect设置一个其他的时区,只给出个结果,一些步骤不再贴出

The following information has been given:

    Anguilla

Therefore TZ='America/Anguilla' will be used.
Local time is now:    Wed Sep 27 12:48:20 AST 2017.
Universal Time is now:    Wed Sep 27 16:48:20 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='America/Anguilla'; 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:
America/Anguilla

追加

[root@ltt1 ~]# vi /etc/profile
TZ='America/Anguilla'; export TZ
[root@ltt1 ~]# source /etc/profile

结果

[root@ltt1 ~]# date -R
Wed, 27 Sep 2017 13:01:30 -0400
[root@ltt1 ~]# cat /etc/sysconfig/clock 
ZONE="Asia/Shanghai"

额,可以看到 由 +0800  变成了 -0400

说明成功了,就是文件内容没有更改,目前不知是什么原因。
