把linux系统从中文设置英文字符集后发生以下报错

首先本系统字符集为中文UTF-8

[root@localhost ~]# more  /etc/sysconfig/i18n
LANG="zh_CN.UTF-8"

修改为英文UTF-8
[root@localhost ~]# vim  /etc/sysconfig/i18n
LANG="EN_US.UTF-8"

source生效
[root@localhost ~]# source   /etc/sysconfig/i18n
LANG="EN_US.UTF-8"

用secureCRT登陆后报以下错误

-bash: warning: setlocale: LC_CTYPE: cannot change locale (EN_US.UTF-8): No such file or directory
-bash: warning: setlocale: LC_COLLATE: cannot change locale (EN_US.UTF-8): No such file or directory

-bash: warning: setlocale: LC_NUMERIC: cannot change locale (EN_US.UTF-8): No such file or directory
-bash: warning: setlocale: LC_TIME: cannot change locale (EN_US.UTF-8): No such file or directory


重新修改为英文UTF-8字符集en为小写

[root@localhost ~]# vim  /etc/sysconfig/i18n
LANG="en_US.UTF-8"

source生效
[root@localhost ~]# source   /etc/sysconfig/i18n
LANG="en_US.UTF-8"

用secureCRT登陆,错误消失，看来是大小写的错误造成的找不到语言环境

[root@localhost ~]#

执行locale命令可以看出错误所在

[root@localhost ~]# locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
