SSH连接告警：-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

问题

ssh 连接登录时报错

Last login: Sat Mar  2 09:58:25 2024 from 10.10.1.1
-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
[root@master01 ~]# 

解决

系统已经设置了默认地区_语言，字符集为en_US.UTF-8，但是在系统中没有定义对应的locale文件，只需要手动生成这个locale文件即可

1.查看当前系统的本地化设置信息

[root@master01 ~]# localectl status
   System Locale: LANG=en_US.UTF-8
       VC Keymap: n/a
      X11 Layout: us
       X11 Model: pc105
[root@master01 ~]# 

2.查看系统当前语言

[root@master01 ~]# echo $LANG
C.UTF-8
[root@master01 ~]# export LANG=en_US.UTF-8
[root@master01 ~]# vim /etc/default/locale
LANG=en_US.UTF-8
LC_TIME=en_DK.UTF-8
[root@master01 ~]# 

3.查看locale库是否存在

如果存在/usr/lib/locale/locale-archive这个文件，先备份再 删除。

[root@master01 ~]# ll /usr/lib/locale/locale-archive
ls: cannot access '/usr/lib/locale/locale-archive': No such file or directory
[root@master01 ~]# 

4.重新生成中文的locate文件

[root@master01 ~]# localedef -f UTF-8 -i en_US en_US.UTF-8

如果执行localedef -f UTF-8 -i en_US en_US.UTF-8命令报以下错误：
[root@master01 ~]# localedef -f UTF-8 -i en_US en_US.UTF-8
failed to set locale!
[error] character map file `UTF-8' not found: No such file or directory
failed to set locale!
[error] cannot read character map directory /usr/share/i18n/charmaps: No such file or directory

安装语言包：
[root@master01 ~]# sudo apt -y install language-pack-en
