决议

Append LC_ALL and the required locale to /etc/environment file and log out for the changes to take effect.

For Example:

Raw

[root@example ~]# locale 
LANG=en_AU.UTF-8
LC_CTYPE="en_AU.UTF-8"
LC_NUMERIC="en_AU.UTF-8"
LC_TIME="en_AU.UTF-8"
LC_COLLATE="en_AU.UTF-8"
LC_MONETARY="en_AU.UTF-8"
LC_MESSAGES="en_AU.UTF-8"
LC_PAPER="en_AU.UTF-8"
LC_NAME="en_AU.UTF-8"
LC_ADDRESS="en_AU.UTF-8"
LC_TELEPHONE="en_AU.UTF-8"
LC_MEASUREMENT="en_AU.UTF-8"
LC_IDENTIFICATION="en_AU.UTF-8"
LC_ALL=

[root@example ~]# cat /etc/locale.conf 
LANG="en_AU.UTF-8"

To set LC_ALL=en_US.UTF-8 append this entry in /etc/environment

Raw

[root@example ~]# cat /etc/environment 
LC_ALL=en_US.UTF-8

Logout and then log in for the effect to take place

Raw

[root@example ~]# locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.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=en_US.UTF-8

This changes can also be performed in /etc/locale.conf however, the Lang parameter will not change and if the output of #localecommand is checked, it will show the original value. To avoid confusion, it is better to modify /etc/environment
