1）升级出问题，ssh登录系统显示
-bash: warning: setlocale: LC_CTYPE: cannot change locale (zh_CN.UTF-8): No such file or directory -bash: warning: setlocale: LC_COLLATE: cannot change locale (zh_CN.UTF-8): No such file or directory -bash: warning: setlocale: LC_MESSAGES: cannot change locale (zh_CN.UTF-8): No such file or directory -bash: warning: setlocale: LC_NUMERIC: cannot change locale (zh_CN.UTF-8): No such file or directory -bash: warning: setlocale: LC_TIME: cannot change locale (zh_CN.UTF-8): No such file or directory
2）猜想问题原因
安装了一个新的glibc库而不是覆盖升级，造成系统中目前至少有两个locale命令，Linux不知道用哪个？而用了新装的/usr/local/glibc-2.14/bin/locale，而不是系统默认的/usr/bin/locale
3）问题排查
联想到安装glibc后出的问题，运行命令
#strace localedef
open("/usr/local/glibc-2.14/lib/locale/zh_CN.UTF-8/LC_MESSAGES", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/glibc-2.14/lib/locale/zh_CN.utf8/LC_MESSAGES", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/glibc-2.14/lib/locale/zh_CN/LC_MESSAGES", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/glibc-2.14/lib/locale/zh.UTF-8/LC_MESSAGES", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/glibc-2.14/lib/locale/zh.utf8/LC_MESSAGES", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/glibc-2.14/lib/locale/zh/LC_MESSAGES", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/glibc-2.14/lib/locale/zh_CN.UTF-8/LC_CTYPE", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/glibc-2.14/lib/locale/zh_CN.utf8/LC_CTYPE", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/glibc-2.14/lib/locale/zh_CN/LC_CTYPE", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/glibc-2.14/lib/locale/zh.UTF-8/LC_CTYPE", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/glibc-2.14/lib/locale/zh.utf8/LC_CTYPE", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/glibc-2.14/lib/locale/zh/LC_CTYPE", O_RDONLY) = -1 ENOENT (No such file or directory)
注：也可以用(# strings /opt/glibc-2.14/bin/locale|grep locale)
查找/usr/local/glibc-2.14/bin目录下没有locale文件夹
4）问题解决
# cp /usr/lib/locale/locale-archive /usr/local/glibc-2.14/lib/locale/locale-archive
5）检查
运行命令
strings /opt/glibc-2.14/bin/locale|grep locale
setlocale b/localeH b/localeH /locale. locale (GNU %s) %s all-locales /usr/local/glibc-2.14/lib/locale/locale-archive locale: %-15.15s archive: /usr/local/glibc-2.14/lib/locale/locale-archive /usr/local/glibc-2.14/lib/locale locale: %-15.15s directory: %.*s /usr/local/glibc-2.14/share/locale Cannot set LC_CTYPE to default locale Cannot set LC_MESSAGES to default locale Cannot set LC_COLLATE to default locale Cannot set LC_ALL to default locale Write names of available locales Get locale-specific information.
问题解决。
