How to specify root’s environment variable

bashrcenvironment-variablesrootsudo

I do rails development. In this app, I need to specify the environment variable LD_LIBRARY_PATH = /usr/local/oracle/lib, but when I run the app with sudo script/server, it doesn't run because that library path is not in root's env.

What should I do to make it work? I tried to put the path under root ./bashrc and it didn't work.

I had a similar problem. I looked in my /etc/sudoers file and I saw these lines:

Defaults    env_reset
Defaults    env_keep = "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR \
                        LS_COLORS MAIL PS1 PS2 QTDIR USERNAME \
                        LANG LC_ADDRESS LC_CTYPE LC_COLLATE LC_IDENTIFICATION \
                        LC_MEASUREMENT LC_MESSAGES LC_MONETARY LC_NAME LC_NUMERIC \
                        LC_PAPER LC_TELEPHONE LC_TIME LC_ALL LANGUAGE LINGUAS \
                        _XKB_CHARSET XAUTHORITY"

To get my environment variable to be there I had to add its name after "XAUTHORITY". In your case you would have:

Defaults    env_keep = "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR \
                        LS_COLORS MAIL PS1 PS2 QTDIR USERNAME \
                        LANG LC_ADDRESS LC_CTYPE LC_COLLATE LC_IDENTIFICATION \
                        LC_MEASUREMENT LC_MESSAGES LC_MONETARY LC_NAME LC_NUMERIC \
                        LC_PAPER LC_TELEPHONE LC_TIME LC_ALL LANGUAGE LINGUAS \
                        _XKB_CHARSET XAUTHORITY LD_LIBRARY_PATH"

Give that a try.

Also make sure that you set BASH_ENV="~/.bashrc" in /etc/environment.
