OpenStack quick install on CentOS 7

This post shows only commands and file modifications without explanation. It is based on http://docs.openstack.org/liberty/install-guide-rdo/

To keep it simple I used the same password for most of services: AdminPass123!

openstack


Install OS CentOS 7.1 x64 minimal on 3 servers. Enable visualization in BIOS on server compute1. File should exists /dev/kvm:

[root@compute1 ~]# ls -l /dev/kvm
crw-rw-rw- 1 root kvm 10, 232 Feb 10 16:33 /dev/kvm

Configure network interfaces as on picture above.

1. Configure controller

Generate ssh private key and upload public key to compute1 and block1:

ssh-keygen
ssh-copy-id 10.4.4.2
ssh-copy-id 10.4.4.3

Update /etc/hosts

cat << 'EOF' > /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.4.4.1 controller
10.4.4.2 compute1
10.4.4.3 block1
EOF

Copy to all servers:

scp /etc/hosts 10.4.4.2:/etc/
scp /etc/hosts 10.4.4.3:/etc/

Disable SELINUX and Firewall

systemctl disable firewalld
systemctl stop firewalld
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
setenforce 0
