linux - 设置LINUX 的时区( set linux time zone) 和locales

访问量: 2111

很多时候,你的LINUX时间显示的不对,不是时间不对,而是时区错了。  (most of the time, the root cause you found the time is not correct is that your linux is not setup with the correct timezone) 

解决办法: for short:   dpkg-reconfigure tzdata

refer to:  http://www.christopherirish.com/2012/03/21/how-to-set-the-timezone-on-ubuntu-server/

You can check your current timezone by just running

$ date
Thu Mar 21 18:02:49 MST 2012

Or checking the timezone file at

$ more /etc/timezone
US/Arizona

So to change it just run

$ sudo dpkg-reconfigure tzdata
And follow on screen instructions. Easy.

修改 locale的办法

: 参考:  https://www.douban.com/note/362250557/

1. 先看该系统中的所有有效locale: 

$ locale -a  

$ locale -a
C
C.UTF-8
POSIX
en_US
en_US.iso88591
en_US.utf8

所以,我们要生成它:

$ sudo locale-gen zh_CN.UTF-8
Generating locales...
  zh_CN.UTF-8... done
Generation complete.

这个时候,再次的 $ locale -a

$ locale -a
C
C.UTF-8
en_US
en_US.iso88591
en_US.utf8
POSIX
zh_CN.utf8

2.  $  sudo locale-gen en_US en_US.UTF-8
Generating locales...
en_US.ISO-8859-1... done
en_US.UTF-8... up-to-date
Generation complete.

3.  $ sudo dpkg-reconfigure locales

4.  $ sudo vim /etc/default/locale (下面的东东可以去掉?  2018-4-18 不确定. 保证执行第五点就可以了)

  2 LANG="en_US.UTF-8"
  3 LANGUAGE="en_US:en"

5. 在 ~/.bashrc中, 添加下面的变量(解决git log无法显示中文的问题 )

export LESSCHARSET=utf-8
export LANG=zh_CN.UTF-8
export LANGUAGE=zh_CN.UTF-8
export LC_ALL=zh_CN.UTF-8
