debian change system language

1. select locales:

2. set language:

1 sudo localectl set-locale LANG=zh_CN.utf8
2 sudo localectl set-locale LANGUAGE=zh_CN.utf8
3 sudo localectl set-locale LC_ALL=zh_CN.utf8

 

3. sudo reboot

-----------------------------------------------

centos默认已经选择了不少locales，直接执行步骤2就能够了。
