  • How to set LC_ALL in Red Hat Enterprise Linux 7?
  • How to set LC_ALL to persist after system reboot?

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 ​​#locale​​command is checked, it will show the original value. To avoid confusion, it is better to modify ​​/etc/environment​​
