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
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_ADDRESS="zh_CN.UTF-8" LC_TELEPHONE="zh_CN.UTF-8" LC_MEASUREMENT="zh_CN.UTF-8" LC_IDENTIFICATION="zh_CN.UTF-8" LC_ALL=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 我的意思是更改完毕！！
