CentOS 7字符集的问题与6有点区别，会出现下面问题，查看是中文，vi进入就变成乱码了
生产中修改配置文件
-
[root @ce1d2002a999 ~]# cat /etc/locale.conf
-
LANG="zh_CN.UTF-8"
改为中文字符集
然后在查看更改后的系统语言变量
-
[root@5c46832b5c01 ~]# locale
-
locale: Cannot set LC_CTYPE to default locale: No such file or directory
-
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
-
locale: Cannot set LC_ALL to default locale: No such file or directory
-
LANG=zh_CN.UTF -8
-
LC_CTYPE= "zh_CN.UTF-8"
-
LC_NUMERIC= "zh_CN.UTF-8"
-
LC_TIME= "zh_CN.UTF-8"
-
LC_COLLATE= "zh_CN.UTF-8"
-
LC_MONETARY= "zh_CN.UTF-8"
-
LC_MESSAGES= "zh_CN.UTF-8"
-
LC_PAPER= "zh_CN.UTF-8"
-
LC_NAME= "zh_CN.UTF-8"

LC_TELEPHONE= "zh_CN.UTF-8"

查看语言包
-
[root@5c46832b5c01 ~]# locale -a
-
locale: Cannot set LC_CTYPE to default locale: No such file or directory
-
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
-
locale: Cannot set LC_COLLATE to default locale: No such file or directory
-
C
-
POSIX
-
en_US.utf8
发现没有中文，安装一个，注意7跟6不一样
# yum install kde-l10n-Chinese
#yum reinstall glibc-common
再次查看
-
[root @ce1d2002a999 ~]# cat test
-
我的意思是
-
[root @ce1d2002a999 ~]# vi test
