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?

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.
