Deploying Devstack successfully in CentOS 7

So, do you want to setup your own openstack infrastructure? With Cinder, Nova, nova API, keystone and the such? That’s easy enough. Here is how to do it.

Step 1. Deploy CentOS7, any basic install should be fine. I deployed using the Rackspace cloud server 8Gigs standard instance type. (standard install should be fine!)

Step 2. Add stack user

adduser stack

Step 3. Add stack to sudoers wheel group, ensuring sudo is there

yum install -y sudo
echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

Step 4. Modify /etc/passwd so that the home directory for stack is /opt/stack . It needs this. And chown

vi /etc/passwd
# make sure home directory for stack is /opt/stack (thats all!)
mkdir /opt/stack
chown -R stack:stack /opt/stack

Step 5. Clone Devstack from git

sudo yum install -y git
su stack
git clone
cd devstack

Step 6. Cp base config sample file

cp samples/local.conf .

Step 7. Deploy stack
