centOS 8 报错:Failed to set locale, defaulting to C.UTF-8 ，Centos8 执行yum 安装软件时提示Failed to set locale, defaulting to C.UTF-8 怎么办？

这里会有两种原因

1. 系统没有安装对应的语言包
2. 没有配置正确的语言环境

一般情况下都是第二种情况居多
首先使用 locale -a 查看已安装的语言包

[root@hecs-131104 data]# 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

C.utf8

POSIX

en_AG

en_AU

en_AU.utf8

en_BW

en_BW.utf8

en_CA

en_CA.utf8

en_DK

en_DK.utf8

en_GB

en_GB.iso885915

en_GB.utf8

en_HK

en_HK.utf8

en_IE

en_IE.utf8

en_IE@euro

en_IL

en_IN

en_NG

en_NZ

en_NZ.utf8

en_PH

en_PH.utf8

en_SC.utf8

en_SG

en_SG.utf8

en_US

en_US.iso885915

en_US.utf8

en_ZA

en_ZA.utf8

en_ZM

en_ZW

en_ZW.utf8

这里有en_US.utf8，所以是第二种情况。执行以下命令即可

echo "export LC_ALL=en_US.UTF-8"  >>  /etc/profile

echo "export LC_CTYPE=en_US.UTF-8"  >>  /etc/profile

source /etc/profile

再次执行命令，就不报那个问题了

[root@hecs-131104 data]# yum install -y yum-utils
