Network Topology
Prerequisite
1. ESXi Server installation.
2. CentOS 7 OS
Note: Remember set the NIC mode to Promiscuous mode, otherwise traffic might be blocked.
RDO OpenStack Installation
1. Pre-installation
- 1 Disable firewall and SELINUX before installation.
[root@ems-vm-controller ~]# systemctl stop firewalld.service
[root@ems-vm-controller ~]# systemctl disable firewalld.service
[root@ems-vm-controller ~]# firewall-cmd — state
not running
[root@ems-vm-controller ~]# sed -i ‘/^SELINUX=.*/c SELINUX=disabled’ /etc/selinux/config
[root@ems-vm-controller ~]# sed -i ‘s/^SELINUXTYPE=.*/SELINUXTYPE=disabled/g’ /etc/selinux/config
[root@ems-vm-controller ~]# grep — color=auto ‘^SELINUX’ /etc/selinux/config
SELINUX=disabled
SELINUXTYPE=disabled
[root@ems-vm-controller ~]# setenforce 0
setenforce: SELinux is disabled1.2 Set enviorment espeically for non-English CentOS
[root@ems-vm-controller ~]# vi /etc/environment
LANG=en_US.utf-8
LC_ALL=en_US.utf-81.3 Configure /etc/hosts
[root@ems-vm-controller ~]# vi /etc/hosts

2.1 Install openstack latest release repos, as of 11/2019 the latest Openstack version is stein.
[root@ems-vm-controller ~]# sudo yum install -y centos-release-openstack-stein

3. OpenStack Configuration
3.1 Preparation
Now we can access Horizon Dashboard from http://10.195.231.213/dashboard
Username and password is stored in /root/keystonerc_admin file.
[root@ems-vm-controller ~]# cat keystonerc_admin
unset OS_SERVICE_TOKEN
export OS_USERNAME=admin
export OS_PASSWORD=’xxxxxxxxxxxx'
export OS_REGION_NAME=RegionOne
export OS_AUTH_URL=http://10.195.231.213:5000/v3
export PS1=’[\u@\h \W(keystone_admin)]\$ ‘export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_IDENTITY_API_VERSION=3
Allinone installation have created networks but again doesn’t met our address scheme, so we need reconfigure the whole network. Demo project also can be deleted.
3.1.1 delete demo project
3.1.2 delete router configuration
3.1.3 delete network configuration
3.2 Configure Network
3.2.1 Configure public network
Note: Physical Network has to been mapping to the name of physical NIC, we can get the name from the stackpack answer file, in our case is “extnet”
[root@ems-vm-controller ~]# grep BRIDGE packstack-answers-20191129–234137.txt
CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=extnet:br-ex
3.2.2 Configure private network
3.2.3 Configure router, and specify public subnet as external network and enable SNAT.
Add private subnet into router.
Here is the final network topology
3.3. Configure security group
By default, only btw default security group traffic is allowed, so if we want to access VM from external network, we have create rules to allow traffic in.
This is how default rule looks like:
3.3.1 Add ICMP traffic allow in rule
3.3.2 Add SSH traffic allow in rule
3.3.3 Final security group configuration
3.4 Create VM instance
3.4.1 Create two VM instance
Now we have two VM instance running, IP address 20.0.0.16 and 20.0.0.203.
Verification
Login to VM-1.
VM-1 is able to ping VM-2, 8.8.8.8 and www.google.com.
Mapping floating IP to VM private IP
VM is able to access external network but we can not access VM from outside. the solution is mapping floating IP to VM private IP address.
5.1 Assoicate Floating IP to VM
5.2 Allocating floating IP
We can access VM by floating IP.
