1. Check whether the Chinese package is installed

You can use the following name to check whether the Chinese installation package is installed in the system.

locale -a |grep "zh_CN"
Copy code

If there is no output, it means there is no installation. Enter the following command to install:

yum groupinstall "fonts" -y
 Copy code

After installation, check which Chinese language packs are installed

[root@iz2ze6adlpez0gy7j13vrmz /]# locale -a | grep "zh_CN"
zh_CN
zh_CN.gb18030
zh_CN.gb2312
zh_CN.gbk
zh_CN.utf8
 Copy code

It indicates that the Chinese language pack has been installed in the system and does not need to be installed again. Important note: if your system still cannot use Chinese according to the following steps, please try the above coding method one by one. For example, change LANG="zh_CN" to LANG="zh_CN.gb18030".

2. Modify the configuration file

Before modifying the configuration file, let's take a look at the current system locale:

# echo $LANG
en_US.UTF-8

# locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
Copy code

Although the Chinese language pack is installed, the local language environment is not Chinese, and the locale.conf configuration file needs to be modified

# vim /etc/locale.conf
LANG="zh_CN"
# source   /etc/locale.conf

vim /etc/locale.conf Enter the edit page and enter i Start editing and finish entering esc Bottom line mode, then enter: wq，Save and exit
 Copy code

You can also modify the locale.conf configuration file using the command:

#  localectl set-locale LANG=zh_CN
 Copy code

Then view the current locale:

# echo $LANG
zh_CN

# locale
LANG=zh_CN
LC_CTYPE="zh_CN"
LC_NUMERIC="zh_CN"
LC_TIME="zh_CN"
LC_COLLATE="zh_CN"
LC_MONETARY="zh_CN"
LC_MESSAGES="zh_CN"
LC_PAPER="zh_CN"
LC_NAME="zh_CN"
LC_ADDRESS="zh_CN"
LC_TELEPHONE="zh_CN"
LC_MEASUREMENT="zh_CN"
LC_IDENTIFICATION="zh_CN"
LC_ALL=
Copy code

3. Whether the verification is successful

[root@node2 ~]# date
2017 Monday, 16 October:30:24 CST
 Copy code

4. Supplementary interpretation of the order

locale -a |grep "zh_CN": list the names of all available common locales, and then filter Chinese

locale -a: lists the names of all available common locales

If you can see the following items, it also indicates that the Chinese language pack has been installed in the system. No more installation is required. What do these items mean?

{language code}_ {country code}. {character set}

zh is the Chinese code, CN is the Chinese code, gb18030,gb2312,utf8 is the language character set

Then each item can be popularly understood as "you speak Chinese, you are in China, and the language character set is gb18030/gb2312/utf8"

If the above items are not found, install the Chinese language pack manually

#yum install kde-l10n-Chinese (about 11M)

Locale: view the current system locale

("en_US.UTF-8" can be understood as "you speak English, you are in the United States, and the language character set is UTF-8")

Each item means:

LANG: language of the current system

LC_CTYPE: language symbols and their classification

LC_NUMERIC: numeric

LC_COLLATE: compare and sort habits

LC_TIME: time display format

LC_MONETARY: monetary unit

LC_MESSAGES: information mainly includes prompt information, error information, status information, title, label, button, menu, etc

LC_NAME: name writing method

LC_ADDRESS: address writing method

LC_TELEPHONE: telephone number writing method

LC_ Measure: measure expression

LC_PAPER: default paper size

LC_IDENTIFICATION: an overview of the information contained in the locale itself

LC_ALL: variable with the highest priority. If this variable is set, all LC_* And LANG variables are forced to follow its value

We can see that although the Chinese language pack is installed, the local language environment is not Chinese

Restart the system

# reboot
 Copy code

5. Solution of garbled code in remote tool SSH Secure

When using remote tools to connect, if linux has Chinese files or directories, garbled codes will appear when displaying. Why Yes, the linux code is UTF-8, while the remote tool defaults to the current system local code, that is, GBK. So the solution is system One or two codes are OK, but the SSH Secure tool cannot set the code, so modify the linux system Unified coding.

Step 1: view the locale of the current system.

This is because it has been modified to gbk code.

Step 2: modify the configuration file locale.conf

# vim /etc/locale.conf
 Copy code

Enter i to enter the editing mode. After editing, press ESC to enter the bottom line mode. Then enter: wq exit and save.

Execute the following command to make the modification effective.

# source /etc/locale.conf
 Copy code

Enter date validation. If you still have problems, you can reboot.
