Things are about to get real! Using OpenStack in containers or VMs isnice for kicking the tires, but doesn't compare to the feeling you getwith hardware.
Prerequisites Linux & Network¶
Minimal Install¶
You need to have a system with a fresh install of Linux. You candownload the MinimalCD forUbuntu releases since DevStack will download & install all theadditional dependencies. The netinstall ISO is available forFedoraandCentOS/RHEL.You may be tempted to use a desktop distro on a laptop, it will probablywork but you may need to tell Network Manager to keep its fingers offthe interface(s) that OpenStack uses for bridging.
'Floating self IP address' – This IP address is shared between 2 BIG-IP systems. IP address assigned to traffic group 'traffic-group-1' is a floating self IP address. Floating selfip is like hsrp virtual ip. It will float to active unit when failover occurs.
- Unlike lunar IPS, Floating IPS is able to apply BPS and IPS patches. Floating.zip 2y Executable. This file is or contains an executable Manual Download.
- Download APK (32.3 MB) Versions This release comes in several variants, See available APKs Using APKPure App to upgrade Floating Apps, fast, free and save your internet data. The description of Floating.
Network Configuration¶
Determine the network configuration on the interface used to integrateyour OpenStack cloud with your existing network. For example, if the IPsgiven out on your network by DHCP are 192.168.1.X - where X is between100 and 200 you will be able to use IPs 201-254 for floating ips.
To make things easier later change your host to use a static IP insteadof DHCP (i.e. 192.168.1.201).
Installation shake and bake¶
Add your user¶
We need to add a user to install DevStack. (if you created a user duringinstall you can skip this step and just give the user sudo privilegesbelow)
Since this user will be making many changes to your system, it will needto have sudo privileges:
Note
On some systems you may need to use sudovisudo.
From here on you should use the user you created. Logout andlogin as that user:
Download DevStack¶
We'll grab the latest version of DevStack via https:
Run DevStack¶
Now to configure stack.sh. DevStack includes a sample indevstack/samples/local.conf. Create local.conf as shown below todo the following:
Set
FLOATING_RANGEto a range not used on the local network, i.e.192.168.1.224/27. This configures IP addresses ending in 225-254 tobe used as floating IPs.Set
FIXED_RANGEandFIXED_NETWORK_SIZEto configure theinternal address space used by the instances.Set
FLAT_INTERFACEto the Ethernet interface that connects thehost to your local network. This is the interface that should beconfigured with the static IP address mentioned above.Set the administrative password. This password is used for theadmin and demo accounts set up as OpenStack users.
Set the MySQL administrative password. The default here is a randomhex string which is inconvenient if you need to look at the databasedirectly for anything.
Set the RabbitMQ password.
Set the service password. This is used by the OpenStack services(Nova, Glance, etc) to authenticate with Keystone.
local.conf should look something like this:
Note
There is a sample local.conf fileunder the samples directory in the devstack repository.
Run DevStack:
A seemingly endless stream of activity ensues. When complete you willsee a summary of stack.sh's work, including the relevant URLs,accounts and passwords to poke at your shiny new OpenStack.
Using OpenStack¶
At this point you should be able to access the dashboard from othercomputers on the local network. In this example that would behttp://192.168.1.201/ for the dashboard (aka Horizon). Launch VMs and ifyou give them floating IPs and security group access those VMs will beaccessible from other machines on your network.
