cat /etc/locale.conf

OR

[[email protected] ~]# cat /etc/locale.conf
LANG=es_US.utf8

[[email protected] ~]# localectl status
System Locale: LANG=es_US.utf8

Before changing the system locale, you must know that which locales are available on the current system, issue the following command:

localectl list-locales

Example: If you want to select a EN_US locale, then you can list all EN_US locales by issue the following command:

localectl list-locales | grep en_US

Outputs:

[[email protected] ~]# localectl list-locales | grep en_US
en_US
en_US.iso88591
en_US.iso885915
en_US.utf8

Change The System Locale

There are two ways to change the system locale by through modifying the “/etc/locale.conf” configuration file or using a new command “localect” which is newly added in centos 7 or RHEL 7 operating system.

Edit “/etc/locale.conf” file using “vim” command and search “LANG” line and change its value as what you want to select the locale. Such as: change locale to “en_us.iso88591”.

vim /etc/locale.conf

Before:

LANG=es_US.utf8

After:

LANG=en_US.iso88591

Save and exit the above configuration file and reboot the system, then the changes will take effect.

Set the system locale via localectl command

To set the default system locale, you can use the following command:

localectl set-locale LANG=<locale name>

you need to replace the locale name as you want to select the locale.

Example: changing the default locale to german locale, issue the following command:

localectl set-locale LANG=de_DE.UTF-8

Outputs:

[[email protected] ~]# localectl set-locale LANG=de_DE.UTF-8
[[email protected] ~]# localectl status
System Locale: LANG=de_DE.UTF-8
VC Keymap: us
X11 Layout: us

Note: you must log on  the system with root user  to  run localectl command .
