I have RHEL 7 and I want to set environment variable for sudo.
I have run sudo su in order toswitch to root user and added export to its .bashrc file. Then I have reloaded them with source.
Now when I run env in root mode it has environment variable. However, when I exit and run sudo env it does not.
Why this is happening?
sudo runs programs in its own, limited environment (see the ENVIRONMENT section of the manual man sudo). It does not implicitly use bash to run programs, so ~/.bashrc is not run, though you can invoke it explicitly:
sudo bash --rcfile=~root/.bashrc -c ProgramAndParameters You can set an environment variable in the run string:
sudo variable=value ProgramAndParameters You can use an alias or function to do either of these by default.
You can alternatively add an environment file to /etc/sudoers (see man sudoers for more information).
sudoers entry as below
%DBTEAM ALL = (oracle) NOPASSWD: ALL DBTEAM --> Group Name
oracle --> oracle user name
switch to Target user Without environment variable sudo -s -u oracle
switch to Target user With environment variable sudo -i -u oracle
