Note that this is a temporary change of locale, which will be changed back to the default value after reboot.

Execute if you want to modify and restart for a long time to continue to take effect

# localectl set-locale.utf8

The essence of this name is to modify the following configuration file / etc/locale.conf, so modifying the locale can also modify the configuration file directly.

# vim / etc/locale.conf Open this file and modify it as follows

LANG=en_US.utf8
