CentOS

Hello
I'm trying set NLS_LANG for Enviroment in Centos 7. I use this command: systemctl set-environment NLS_LANG = 'CZECH_CZECH REPUBLIC.UTF8'
It works but after the reboot system this settings is gone. How can I configure this permanently?
Thank you

Add it to "DefaultEnvironment=" in the file /etc/systemd/system.conf

See:

OK I tryed add this into /etc/systemd/system.conf
DefaultEnvironment=NLS_LANG = 'CZECH_CZECH REPUBLIC.UTF8'
Nothing happened.

So I solved problem that I put systemctl command into startup scrypt: /etc/rc.d/rc.local and it works.

According to man systemd-system.conf, the syntax is: You appear to have the quotes in different positions.

Thank you. My Fault.
I added correctly DefaultEnvironment="NLS_LANG='CZECH_CZECH REPUBLIC.UTF8'"
Now it works
