perl: warning: Setting locale failed

登录到新安装的CloudLinux服务器后，您可能会在控制台上注意到以下输出：

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LC_CTYPE = "UTF-8";,
LANG = "en_US.UTF-8";
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C";).
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LC_CTYPE = "UTF-8";,
LANG = "en_US.UTF-8";
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C";).

这并不代表任何重大问题，但随着时间的流逝会很烦人。
要摆脱这些提示，请执行以下过程。

1.使用您喜欢的文本编辑器编辑以下文件：

/etc/environment

2.附加以下内容：

LANGUAGE = "en_US:en",
LC_ALL = "en_US.UTF-8",
LC_CTYPE = "UTF-8",
LANG = "en_US.UTF-8"

注意：默认情况下，文件应为空白。
如果使用其他语言或者编码，则可以调整以上内容以满足您的要求。
