Error in sudoers list

Question

I have been trying to install Openstack on centos using devstack. When I run the script, I get the following error:

[vagrant@centos64 devstack]$ ./stack.sh 
sudo: >>> /etc/sudoers.d/50_stack_sh: syntax error near line 1 <<<
sudo: >>> /etc/sudoers.d/50_stack_sh: syntax error near line 2 <<<

Now, here is /etc/sudoers.d/50_stack_sh file:

[root@centos64 devstack]# cat /etc/sudoers.d/50_stack_sh
 ALL=(root) NOPASSWD:ALL
Defaults: secure_path=/sbin:/usr/sbin:/usr/bin:/bin:/usr/local/sbin:/usr/local/bin

I tried to edit it, but it says it's a read only buffer, even for root user. I tried to add vagrant user to the sudoers group by editing /etc/sudoers file, but it gave the same error as it is a read only buffer. How do I resolve this error?

Answer 1

The main problem that you need a password less sudo user to be able install devstack. Try to run: devstack/tools/create-stack-user.sh After that it should work.

Answer 2

To recap the context:

• I have installed CentOS 7 (1503) minimal.

• As root:

  • I ran the command:

    git clone https://git.openstack.org/openstack-dev/devstack
    

  • I ran the command devstack/tools/create-stack-user.sh: it created a stack user and create the file /etc/sudoers.d/50_stack_sh. But that file has syntax error.

    To fix it, I edit the file /etc/sudoers.d/50_stack_sh to have this content:

    stack ALL=(ALL) NOPASSWD: ALL
    Defaults secure_path=/sbin:/usr/sbin:/usr/bin:/bin:/usr/local/sbin:/usr/local/bin
    Defaults !requiretty
    

    To force the saving with VIM, you need to type :w!

Hope it helps,

I had this problem as well. It wasn't a problem with the stack.sh script, as you can run something (as the stack user) like "sudo yum update" and it will produce the same problem.

It comes from a syntax error in the /etc/sudoers.d/50_stack_sh file. You can get away with running (as root)

echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

My stack.sh seems to be working well now

Answer 4

There is my way to fix it. I cd to the /etc/sudoers.d/,and then delete the file 50_stack_sh. It works,and now your user can good work.You can change to the user which you want to run devstack and run the script ./stack.sh . Hope it helps!
