Linux cannot input Chinese

Environment:

Server environment: Ubuntu Server 16.04 lts

Server encoding configuration:

First, we use a shell connection to log in to the server, and then enter the locale command in the terminal. The results are as follows:

$ locale LANG= LANGUAGE=C: LC_CTYPE="POSIX" LC_NUMERIC="POSIX" LC_TIME="POSIX" LC_COLLATE="POSIX" LC_MONETARY="POSIX" LC_MESSAGES="POSIX" LC_PAPER="POSIX" LC_NAME="POSIX" LC_ADDRESS="POSIX" LC_TELEPHONE="POSIX" LC_MEASUREMENT="POSIX" LC_IDENTIFICATION="POSIX" LC_ALL=

(free video tutorial recommendation:linux video tutorial)

The meaning of each option is as follows:

Language symbols and their classification (LC_CTYPE)

Numbers (LC_NUMERIC)

Comparison and sorting Habit (LC_COLLATE)

Time display format (LC_TIME)

Currency unit (LC_MONETARY)

The information is mainly prompt information, error information, status information, title, label, button and menus, etc. (LC_MESSAGES)

Name writing method (LC_NAME)

Address writing method (LC_ADDRESS)

Telephone number writing method (LC_TELEPHONE)

Weights and measures Expression (LC_MEASUREMENT)

Default paper size (LC_PAPER)

Overview of the information contained in the locale itself (LC_IDENTIFICATION).

What we want to fix is the Chinese input problem, so we only need to setLC_CTYPEnext.

Check the encoding method supported by the system:

locale -a

Check whether the output content contains zh_CN.utf-8. If not, you can install the language pack first.

sudo apt-get -y install language-pack-zh-hans

zh_CN.utf-8 has been included after installation

Next, modify the value of LC_CTYPE and use theexport LC_CTYPE='zh_CN.UTF-8'command to modify it .

Direct executionexport LC_CTYPE='zh_CN.UTF-8'Then it is only valid for the current session

All users (permanent): modify /etc/profile

Current user (permanent): Modify ~/.bashrc

It is recommended to modify the /etc/profile file directly so that all users can use it.

After the modification is completed, log out, log in again, and then enter thelocalecommand, you can get the following output:

LANG= LANGUAGE=C: LC_CTYPE=zh_CN.UTF-8 LC_NUMERIC="POSIX" LC_TIME="POSIX" LC_COLLATE="POSIX" LC_MONETARY="POSIX" LC_MESSAGES="POSIX" LC_PAPER="POSIX" LC_NAME="POSIX" LC_ADDRESS="POSIX" LC_TELEPHONE="POSIX" LC_MEASUREMENT="POSIX" LC_IDENTIFICATION="POSIX" LC_ALL=

After that, you can enter Chinese:
