Xshell登录linux系统时会出现报错： -bash: warning: setlocale: LC_CTYPE: cannot change locale (latin1): No such file or directory -bash: warning: setlocale: LC_COLLATE: cannot change locale (latin1): No such file or directory -bash: warning: setlocale: LC_MESSAGES: cannot change locale (latin1): No such file or directory -bash: warning: setlocale: LC_NUMERIC: cannot change locale (latin1): No such file or directory -bash: warning: setlocale: LC_TIME: cannot change locale (latin1): No such file or directory 由于之前修改过系统和mysql服务端字符集，全部修改成latin1后才出现这个情况： [root@mysql ~]# cat /etc/sysconfig/i18n LANG="latin1" SYSFONT="latarcyrheb-sun16" 还原成原来的en_US.UTF-8，后su -和重启就不会出现这个情况。
