LC_CTYPE: cannot change locale (en_US.

升级glibc库后，使用SecureCRT登录linux，提示:

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

执行more /etc/sysconfig/i18n命令检查系统字符集

[root@dashuju172 ~]# more  /etc/sysconfig/i18n 

LANG="en_US.UTF-8"

SUPPORTED="zh_CN.GB18030:zh_CN:zh:zh_CN.UTF-8:en_US:en"

SYSFONT="latarcyrheb-sun16"

执行locale命令,提示如下异常，说明说明没安装en_US的local

[root@dashuju172 ~]# 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=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=

解决方案，修改如下：

vi /etc/sysconfig/i18n

# 添加下面的

LC_ALL=C

export LC_ALL

# 再执行下面的语句，使之生效

source /etc/sysconfig/i18n
