bug宝典linux篇 LC_CTYPE: cannot change locale (en_US.UTF-8): No such file or directory（转）

升级glibc库后，使用xShell登录linux，提示:

 To escape to local shell, press Ctrl+Alt+].

执行more /etc/sysconfig/i18n命令检查系统字符集

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

 vim /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

LC_ALL=C的含义
