系统为redhat entpr linux rhel8.1，上传中文文件或文件中包含中文，中文显示乱码。
执行locale，报如下错误
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
已经根据网上资料设置/etc/locale.conf 文件LANG=zh_CN.UTF-8
已经安装语言包，langpacks-zh_CN-1.0-12.el8.noarch.rpm，如下
Failed to set locale, defaulting to C.UTF-8

Nothing to do.
Complete!
修改 /etc/profile 也没起作用
已经重启机器，locale -a仍然没有zh_CN，中文仍然为乱码
