I want to create system user without password and home directory. I found some similar solution but not properly get my answer. I am using a centos machine.
in ubuntu: adduser mprobe --disabled-password --system --no-create-home --group
its working but in centos it says disable-password not found.
thanks in advance.
AFAIK adduser isn't a coreutils command, it's just a convenience script, so it may vary drastically from distro to distro. A quick Google search yields, that password could be disabled for an existing user with passwd -d <username>. So my recommendation would be to:
sudo -s # Enter a root shell then:
adduser mprobe --system --no-create-home --group # Create the user in question passwd -d mprobe # Delete its password exit # Drop root privileges
