I am setting up a shared folder between several users on a Amazon AMI (details at the bottom). I am trying to get the folder shared with one user in particular which isnt working.
My idea was to create a user group called "repository" which I would add the users to. I ran the following commands:
sudo groupadd repository
sudo usermod -a -G repository jenkins
sudo usermod -a -G repository ec2-user
sudo mkdir /repository
sudo chown jenkins:repository /repository
sudo chmod 770 /repository
now at this point I would expect the jenkins user would have no troubles making a directory in this folder. However it doesnt seem to be working.
sudo runuser -l jenkins -c "mkdir /repository/hello"
doesnt make a directory. Trying the ec2-user which is also part of the "repository" group.
sudo runuser -l ec2-user -c "mkdir /repository/hello"
makes a directory successfully. Double checking using groups jenkins and groups ec2-user verifies that the both users are part of the "repository" group.
Where am I going wrong? Is the jenkins user being a service account the problem?
The jenkins account in question is for a Jenkins webserver and the user can be changed but I would like to keep it the same.
Heres the os details:
>cat /etc/*-release
NAME="Amazon Linux AMI"
VERSION="2015.03"
ID="amzn"
ID_LIKE="rhel fedora"
VERSION_ID="2015.03"
PRETTY_NAME="Amazon Linux AMI 2015.03"
ANSI_COLOR="0;33"
CPE_NAME="cpe:/o:amazon:linux:2015.03:ga"
HOME_URL="http://aws.amazon.com/amazon-linux-ami/"
Amazon Linux AMI release 2015.03
Found a solution but dont know why it works
After some more poking around I ended up changing the shell for the jenkins user from /bin/false to /sbin/nologin and everything worked fine after. Could anyone explain why using /bin/false would have caused this?
So in /etc/passwd
from: jenkins:x:498:498:Jenkins Continuous Integration Server:/var/lib/jenkins:/bin/false
to: jenkins:x:498:498:Jenkins Continuous Integration Server:/var/lib/jenkins:/sbin/nologin
