Study OpenStack Octavia in Mitaka by using DevStack (1)

Octavia

You must prepare ram greater equal than 32GB. That's in my minimum ram testing.
In my previous testing, I only have 4GB ram, it always failed and cannot launch Amphora.
So don't make the mistake.

Installation

You can see my previous Blog to show how to install DevStack Mitaka.

http://gogosatellite.blogspot.tw/2016/04/using-devstack-to-install-openstack.html

Here is the local.conf.

Create Backend Server

Be patient, We lauch Backend Server first.

You can see my previous Blog to download and hack a Ubuntu VM.

http://gogosatellite.blogspot.tw/2016/08/html-charsetutf-8-cloud-vm-to-use-user.html

After launch a Ubuntu VM and run a SimpleHTTPServer.

python -m SimpleHTTPServer 80

where we enable port 80.

Create Octavia Service

Horizon

You can easily use Horizon to launch Octavia service. It's quite simple. Mention that you must add the Backend VM as member VM and adding floating IP to Amphora.

After Create Octavia Service.

After that, wait for 5min+ util you see the log from o-cw.log.

tail -f o-cw.log -n 100
.

Where Load Balancer 2 is our target.

Remodify Security Group of the Amphora and VM

It's quite important that if you can not connect to the backend server, it probly is due to security group. So we allow all traffic connected in the network to avoid problem. Mention that, when you create Octavia Service by user Demo, the Amphora VM is launched by admin (not Demo). You will not see the Amphora VM information in user Demo, but you can see the Octavia Service in User Demo. If you are using Horizon, switch to admin user and check the instance you will see the Amphora VM running on user admin not demo.

So if you want to allow all traffic in the network, you must remodify security group for both user demo and admin.

Security Group in User Demo

To allow all traffic, you can use Horizon to enable icmp, tcp, udp, dns, http, ssh for ingress and egress.

stack@devoct:~/devstack$ nova secgroup-list-rules default

You can use admin to see the detailed of Amphora instance and you will find the 10.0.0.18 is the IP of the Amphora.

And you can ping this IP, 10.0.0.18, from backend server for trouble shooting to make sure the security group with right setting.

Debug

• No neutron-lbaasv2-agent Daemon in Mitaka version /usr/bin/python /usr/local/bin/neutron-lbaasv2-agent --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/services/loadbalancer/haproxy/lbaas_agent.ini

• Memory too Small

Please make sure you have large memory, since I waste a lot of time to debug it, since the Amphora cannot be launched. The following is the error message:

Cannot set up guest memory 'pc.ram': Cannot allocate memory

After enlarge memory to 32GB and Disk to 50GB, everything seems better.

Hacking Ubuntu Cloud Image to Have Your Own User and Password

Hacking Cloud VM to use User password to Login

Most of cloud image use key-pair to login. It's really hard for a beginner.
There is a way to hack the cloud image to login with usual user and password without keypairs.
This is a greate tool for me.

Hacking the Cloud VM

Download backdoor-image

$bzr branch lp:~smoser/+junk/backdoor-image

You might need to install bzr through apt-get install bzr.

Into backdoor-image folder

$cd backdoor-image

Download a Ubuntu cloud image

$ wget http://cloud-images.ubuntu.com/precise/current/precise-server-cloudimg-amd64-disk1.img

cp image to a backup image

$cp precise-server-cloudimg-amd64-disk1.img ubuntu12.04-server-cloudimg-amg64-disk1.img

Set the user and password to the cloud image

$./backdoor-image --user ubuntu --password ubuntu --password-auth ubuntu12.04-server-cloudimg-amg64-disk1.img

Perfectly

努力升级

最近好多周邊配備升級了，包含我的MAC電腦也升級SSD。
自己也該隨著升級，心態，能力，都該升級了。
更努力，更專注，更投入，才行。

OpenStack(kilo): Dynamically Adding Nic Card to VM

OpenStack(kilo): Adding Nic Card to VM

Dynamically adding a Nic to VM without reboot.

Initially, In the VM, we have eth0 only.

$ip link list
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether fa:16:3e:2e:50:12 brd ff:ff:ff:ff:ff:ff

Attach Nic Card to VM

Command Line

If you are using DevStack, you can use the command source openrc admin demo. So that you can use OpenStack command line.

To add Nic Card to VM, we can use the following commands.

neutron port-create private
neutron port-list
nova interface-attach --port-id <portid> <instanceName>
nova interface-detach <instanceName> <portid>

You then can login to VM, and check nic card with ip link list command.

It's very simple, really. And now we can discuss it more detailed.

Detailed Command with debug mode

The most important thing is to study how to call rest-api. You can use DEBUG mode.

SVM演算法於python的使用

前言

在很久以前，我是做演算法的，我记得，我最后一个接触的演算法就是SVM。 但那时只到听过这个演算法而已。 几年后，竟然有机会接触到演算法，竟然还是SVM。这过程真有趣。 以前总是想实现算法，现在python实在太方便了，lib呼叫就什么事情都解决了。

这也是当初我学Golang，最后转回python的原因。python的lib太强大了。

也感谢，聪明又美丽的北一女学妹，给我以下的blog，加速我的学习。

SVM用法

from sklearn import svm
X = [[0, 0], [1, 1],[2, 2]]
y = [0, 1, 2]
clf = svm.SVC()
clf.fit(X, y)
print clf.predict([[5., 5.]])

X為多維的training data，y為label。

One-Class SVM

What's the meaning of nu

http://qiita.com/SE96UoC5AfUt7uY/items/88006646179adf68cb95

One-Class SVM，异常判定。 有的时候，我们有大量资料，我们只想知道，我们现在的资料是否为异常。 我们可以用以下的方式，实现。

from sklearn import svm
X = [[0, 0], [1, 1],[2, 2]]
y = [0, 1, 2]
clf = svm.OneClassSVM(nu=0.1, kernel="rbf", gamma=0.1)
clf.fit(X)

print clf.predict([[3, 3]])

return值-1為異常。
