Openstack Train Installation on Oracle Virtual Box (1)

<Laptop Spec>

CPU : 4 Cores, I7-8650U

RAM : 64GB

OS : Window 10

 

 

<Pre-requirement>

1. Oracle VirtualBox installation

2. Centos7 download

 

 

 

<Setting up Oracle VirtualBox>

1. Creating Controller and Compute VM

   1.1 Controller VM Creation

VM name, OS selection, Memory Size 25GB

 

Disk Size, Disk location

   1.2 Compute VM Creation

 

Compute VM, Memory size 25GB

Disk Location and Disk Size

 

2. Setting up Network of VM  

   2.1 Host-Only Network

   Global Tools > Create > IP address : 10.10.1.1, mask : 255.255.255.0 > Apply

   This Host-Only Network is for SSH connection to VMs from the host

 

   2.2 Network Topology for Openstack

Oracle Virtual Box Network

  

   2.3 Setting VM Network

      2.3.1 Controller and Compute VM Network

      Controller > Settings > Network

      VMs have two interfaces. one is for External. another one is internal.

      Bridged Adapter is for External.

Bridge mode for External

        Adapter2 is for the Internal network between Compute and Controller node.

        * Note : Host-Only Ethernet Adapter for 192.168.56.0/24

     

      Host-only for SSH connection from host to internal VMs

      Please take care of Adapter2 name which you created

 

         Please set the compute node network adapters which is same with controller.

 

 

 

<CentOS 7 Installation>

I will pass these steps. please install Centos7 minimal package.

 

1. Network status on Controller.

enp0s3 is under my home AP network as bridge mode. it got IP through DHCP from my HOME AP.

enp0s8 is NAT Network to communicate between only controller and compute. no need to connecte to internet.

enp0s9 is Host-only for SSH connection to VM on compute or controller.

<Setting up Environment for openstack>

1. Disable NetworkManager on both Controller and Compute

[root@Controller network-scripts]# systemctl stop NetworkManager [root@Controller network-scripts]# systemctl disable NetworkManager [root@Controller network-scripts]# systemctl status NetworkManager ● NetworkManager.service - Network Manager    Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service; disabled; vendor preset: enabled)    Active: inactive (dead)      Docs: man:NetworkManager(8)

2. Disable Firewall on both

[root@Controller network-scripts]# systemctl stop firewalld [root@Controller network-scripts]# systemctl disable firewalld [root@Controller network-scripts]# systemctl status firewalld

 

3. Setup Hostname

[root@Controller network-scripts]# vim /etc/hosts 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.32 compute [root@compute network-scripts]# vim /etc/hosts 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.31 controller

 

4. SELINUX on both

setenforce 0 [root@Controller ~]# vim /etc/selinux/config #SELINUX=enforcing SELINUX=permissive

 

 

5. Update YUM

[root@Controller network-scripts]# yum update -y
