使用 Amazon Linux AMI 启动 EC2 时文件丢失

Question

I've just launched an t2.micro free tier EC2 instance and SSH into it from my local machine. And I was welcomed by an error message as below:

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

This instance was launch using the console and every option has been by default and nothing special being configured. What could be the reason for it?

Below is the Locale of this instance:

[root@ip-xxx .aws]# locale
locale: Cannot set LC_CTYPE 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=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=

Answer 1

in my case it was required to add following lines to /etc/environment

LANG=en_US.utf-8
LC_ALL=en_US.utf-8

Answer 2

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

Also for later use add the same two commands to ~/.bash_profile
