典型错误:locale.Error:unsupported locale setting
1、错误提出
(1)locale指令运行出现的错误信息
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
(2)setup指令运行出现的错误信息
locale.Error:unsupported locale setting,导致无法设置“network configuration”
(3)yum指令运行出现的错误信息
Failed to set locale, defaulting to C
2、分析原因
locale是用来设置软件运行的语言环境,所以语言环境设置有问题
3、解决故障
重新设置语言环境,最简单的解决办法,例如:
[root@Mylinux ~]# echo “export LC_ALL=en_US.UTF-8” >> /home/XXX/.bash_profile(特定用户)
或者
[root@Mylinux ~]# echo “export LC_ALL=en_US.UTF-8” >> /etc/profile(所有用户)
[root@Mylinux ~]# exit
然后重新登录,使用locale指令查看变量
