Linux Ubuntu Server 14.04 LTS processes Chinese Garbled text and vi editor operations, ubuntu14.04

First, I searched for some information on the Internet, saying that it was temporarily unavailable.

However, during installation, the installation is performed in Chinese. Therefore, the command page displays Garbled text.

Since it is a Linux service version, I think there is no need to install a Chinese package. I decided to switch back to english display.

======================

1. Use the command cd etc/default to switch to this directory, and then modify the content in the locale file;

2. to modify the locale file, the permissions of ordinary users are insufficient. What should I do? By default, The sudo command can get the root permission for 5 minutes, that is, sudo vi locale;

In this way, go to the vi editor and edit it.

Change all Chinese encoding to English encoding.

3. Save the modification and restart the operating system;

=============================== Appendix 1
