Physical Node Configuration
1, enable kvm nested virtualization feature
kvm-ok
cat /sys/module/kvm_intel/parameters/nested
This should output Y, if it doesn’t do the following:
sudo modprobe -r kvm_intel
sudo modprobe kvm_intel nested=1
2, sudo apt-get update && sudo apt-get dist-upgrade
sudo apt-get install -y bridge-utils qemu-kvm qemu-utils libvirt-bin virt-viewer cpu-checker virtinst uvtool
sudo apt-get install -y virt-manager qemu-system spice-client-gtk spice-vdagent python-spice-client-gtk
3, Ensure $USER is added to libvirtd group.
groups | grep libvirtd
4, Ensure host machine has SSH keys.
ssh-keygen -t rsa
5, create one KVM virtual network named cloud via NAT with dhcp, 192.168.100.0/24 (192.168.100.3 - 192.168.100.9)
6, crate a kvm vm named maas-server (IP: 192.168.100.3, usename: ubuntu)
sudo virt-install --connect qemu:///system -n maas -r 2048 \
--arch=x86_64 -c /images/iso/ubuntu-16.04.2-server-amd64.iso \
--vnc --accelerate \
--disk=/images/kvm/maas.img,size=15 \
--network=network=cloud,model=virtio
如果嫌分步安装maas麻烦的话，可以直接在这里选择“multiple server install with MAAS”安装带有MAAS的ubuntu server, 步骤见：https://maas.ubuntu.com/docs/install.html
vi /etc/network/interface
auto eth0
iface eth0 inet static
address 192.168.100.3
netmask 255.255.255.0
gateway 192.168.100.1
# dns-nameservers 8.8.8.8
$ cat /etc/resolvconf/resolv.conf.d/base
search localdomain
nameserver 192.168.100.1
sudo resolvconf -u
MAAS-Server VM Configuration
http://dinosaursareforever.blogspot.co.uk/2014/06/manually-deploying-openstack-with.html
上面是maas 1.9的架构图, 自maas 2.0之后架构图如下:
- Region相当于一个数据中心, Region下再划分fabric, rack controller is attached to each "fabric", rack controller应该为了性能缓存镜像.
- 可以看到, 1.9的cluster就是2.0的rack, 所以maas-cluster-controller包也变成了maas-rack-controller包.
- rack controller可以连接多个VLANs, region controller提供了HTTP端口5240(MAAS HA后则是80)和10个RPC端口(5250-5259共10个给maas-regiond使用)和rack controller通讯. 默认每5分钟rack controller需要和regiond通讯同步镜像.
1, install postgresql and create database maasdb with the user maas, thus maas package will create tables in the database maasdb
export LC_ALL="en_US.UTF-8"
sudo apt-get update
sudo apt-get install postgresql
坑一，Fix the problem No PostgreSQL clusters exist; see "man pg_createcluster"
sudo pg_createcluster 9.3 main --start #如果postgres能启动就不需要下面的步骤了
坑二，有时候报错 psql: FATAL: password authentication failed for user "postgres"
那是因为postgresql和juju都使用了md5，
a, 临时禁掉postgresql里的md5, 将/etc/postgresql/9.3/main/pg_hba.conf文件里搜索md5，将其改为trust，如：
local all all trust
b, juju总会在/etc/maas/maas_local_settings.py 文件中生成一个固定的md5的密码，用下列命令将两者密码修改为一致。
psql -c "ALTER USER maas WITH PASSWORD '1Vl1WwwB5MNJ'" -d template1
sudo mkdir -p /usr/local/pgsql/data
sudo chown -R postgres:postgres /usr/local/pgsql/
sudo mkdir /var/run/postgresql & sudo chown -R postgres:postgres /var/run/postgresql
sudo su - postgres
cd /usr/lib/postgresql/9.3/bin/
./initdb -D /usr/local/pgsql/data
./postgres -D /usr/local/pgsql/data
ubuntu@maas:~$ sudo su - postgres
[sudo] password for ubuntu:
postgres@maas:~$ psql -d template1 -U postgres
psql (9.3.7)
Type "help" for help.
template1=# create user maas with password ''; # 配置文件： /etc/maas/maas_local_settings.py
CREATE ROLE
template1=# create database maasdb;
CREATE DATABASE
template1=# grant all privileges on database maasdb to maas;
GRANT
ubuntu@maas:~$ sudo su - maas
ubuntu@maas:~$ psql -d maasdb -U maas
psql (9.3.7)
Type "help" for help.
maasdb=> \l
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
-----------+----------+----------+-------------+-------------+-----------------------
maasdb | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =Tc/postgres +
postgres=# \c maasdb
You are now connected to database "maasdb" as user "postgres".
maasdb=# \dt
也修改/etc/maas/maas_local_settings.py 文件将用户名和密码数据库等信息设置的和上述一样。
2, install maas
sudo apt-get update
sudo apt-get install -y software-properties-common
sudo apt-add-repository ppa:maas-maintainers/stable
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install maas
坑三，安装maas后看不到images标签页，请使用这个源”sudo apt-add-repository ppa:maas-maintainers/stable“
要更改maas ip的话，还需要：
sudo dpkg-reconfigure maas-region-controller
sudo dpkg-reconfigure maas-cluster-controller
maas - seed cloud setup, which includes both the region controller and the cluster controller below.
maas-region-controller - includes the web UI, API and database.
maas-cluster-controller - controls a group (“cluster”) of nodes including DHCP management.
maas-dhcp/maas-dns - required when managing dhcp/dns.
fix one problem: ubuntu 14.04 said the password is not right after locking the machine, but can login the system after switching the account:
sudo chown root:shadow /etc/shadow then sudo chmod u=r,g=r /etc/shadow
3, create admin user
sudo maas-region-admin createadmin --username=admin --email=admin@163.com
http://192.168.100.3/MAAS (/etc/apache2/conf-enabled/maas-http.conf)
We can use the simple VPN sshuttle when visting it outside, sshuttle -D -r <hypervisor IP> 192.168.100.0/24
4, Import boot images
if you want to limit the types of boot images that can be created you need to edit /etc/maas/bootresources.yaml
hua@maas:~$ sudo maas-region-admin apikey --username admin > ~/maas-apikey
hua@maas:~$ maas login myprofile http://192.168.100.3/MAAS `cat ~/maas-apikey
You are now logged in to the MAAS server at
http://192.168.100.3/MAAS/api/1.0/ with the profile name 'myprofile'.
For help with the available commands, try:
maas my-maas-session --help
在这个界面http://192.168.100.3/MAAS/images/导入镜像，
或者API命令 maas myprofile node-groups import-boot-images
还可以使用本地镜像加速导入过程，https://maas.ubuntu.com/docs/install.html
成功后，如下图：
5, 今后需要访问maas node的机器的公钥(~/.ssh/id_rsa.pub)都应该在http://192.168.100.3/MAAS/account/prefs/界面注册, 这样在通过juju部署服务时，机器才被分配给具体用户，此时Juju才会将该这些公钥注到maas node里，这样用户就可以访问属于他自己的maas node了。（注意：是不能通过用户名和密码方式访问的，仅仅也要maas node被分配给具体用户之后也即从Ready状态变到Deployed状态之后才是可以通过ssh公钥登录的）
6, configure dhcp and dns, edit the eth0，http://192.168.100.3/MAAS/clusters/445476e3-fc38-411a-97c6-775c2b6be4ca/interfaces/eth0/edit/
Interface: eth0
Management: DHCP and DNS
注意, 一选dhcp and dns就报“Internal server error", 选"dhcp"可以. 那是因为执行sudo service bind9 restart时报错“rndc: connect failed: 127.0.0.1#953: connection refused”，
需要：sudo mkdir -p /etc/named/maas && sudo touch /etc/named/maas/named.conf.maas
见：https://bugs.launchpad.net/ubuntu/+source/maas/+bug/1266840
必须使用maas dns服务，并且maas server和maas node都必须使用maas dns服务，这样才能解析maas node的hostname以确保juju的正常运行。
所以在maas server节点中的/etc/resolvconf/resolv.conf.d/head文件中添加下列内容后，再执行“sudo resolvconf -u"命令。至于maas node会由maas自动添加到/etc/resolv.conf文件。
nameserver 192.168.100.3
search maas
不使用maas dns服务的话会无法解决maas node的域名和其他的域名如archive.ubuntu.com（因为maas node的nameserver会由maas默认指定为192.168.100.3)，这样后续的如juju bootstrap时就会访问访问不了域名archive.ubuntu.com从而出错, 例如：
Command: ['curtin', 'curthooks']
Exit code: 3
Reason: -
Stdout: "Ign http://archive.ubuntu.com trusty InRelease\nIgn http://archive.ubuntu.com trusty-updates InRelease\nIgn http://archive.ubuntu.com trusty-security
。。。。
. No error reported.\numount: /tmp/tmppl9cvQ/target/dev: device is busy.\n (In some cases useful info about processes that use\n the device is found by lsof(8) or fuser(1))\nUnexpected error while running command.\nCommand: ['umount', '/tmp/tmppl9cvQ/target/dev']\nExit code: 1\nReason: -\nStdout: ''\nStderr: ''\n"
Stderr: ''
另外也需要在 http://192.168.100.3/MAAS/settings/中的”Upstream DNS used to resolve domains not managed by this MAAS“选项中设置maas使用的上游dns服务器.
还需要设置/etc/bind/named.conf.options中的dnssec-validation no;
最后，重启dns服务，sudo service bind9 restart
IP: 192.168.100.3
Subnet mask: 255.255.255.0
Broadcast IP: 172.16.1.255
Router IP: 192.168.100.1
IP Range Low: 192.168.100.10 #是maas node在ready状态未分配给用户使用前（即非deployed状态时）临时使用的ip
IP Range High: 192.168.100.99
IP Static Range Low: 192.168.100.100 #是maas node在deployed状态时用的ip
IP Static Range High: 192.168.100.199
重启所以maas服务：
sudo service maas-clusterd restart
sudo service maas-dhcpd6 restart
sudo service maas-dhcpd restart
MAAS Nodes Installation
1, 创建一个专用的maas用户，
sudo apt-get install libvirt-bin
sudo chsh maas -s /bin/bash
sudo su - maas
ssh-keygen
在maas执行里执行命令（ssh-copy-id -i ~/.ssh/id_rsa hua@192.168.100.1）让maas虚机可以无密码访问物理机上的libvirt
测试：
ubuntu@maas:~$ sudo -u maas virsh -c qemu+ssh://hua@192.168.100.1/system list --all
Id Name State
----------------------------------------------------
3 maas running
2, 在物理机上执行下列脚本通过pxe方式创建两个虚机来模拟maas的节点, 用于安装openstack的控制节点（可以用4G内存）和计算节点（用2G内存）。
sudo apt-get install virtinst
qemu-img create -f qcow2 /bak/images/maas-controller.qcow2 12G
virt-install --noautoconsole --pxe --boot network,hd,menu=on \
--graphics spice --video qxl --channel spicevmc \
--name maas-controller --ram 4096 --vcpus 1 \
--controller scsi,model=virtio-scsi,index=0 \
--disk path=/bak/images/maas-controller.qcow2,format=qcow2,size=12,bus=scsi,cache=writeback \
--network=network=cloud,mac=52:54:00:63:7e:7c,model=virtio \
--network=network=cloud,mac=52:54:00:63:7e:7d,model=virtio
qemu-img create -f qcow2 /bak/images/maas-compute.qcow2 12G
virt-install --noautoconsole --pxe --boot network,hd,menu=on \
--graphics spice --video qxl --channel spicevmc \
--name maas-compute --ram 2048 --vcpus 1 \
--controller scsi,model=virtio-scsi,index=0 \
--disk path=/bak/images/maas-compute.qcow2,format=qcow2,size=12,bus=scsi,cache=writeback \
--network=network=cloud,mac=52:54:00:63:7e:7a,model=virtio \
--network=network=cloud,mac=52:54:00:63:7e:7b,model=virtio
坑四，有时候创建了maas node之后，在界面中的Nodes菜单中不显示，重启maas有时候能好。
sudo service maas-clusterd restart
sudo service maas-dhcpd6 restart
sudo service maas-dhcpd restart
3, 给maas节点注册vish电源管理模式，对于裸机使用IPMI, 这样maas就可以控制maas node的启停了。
Power type: virsh (virtual systems)
Power Address: qemu+ssh://hua@192.168.100.1/system
Power ID: 虚机的名字，即maas-controoler或maas-compute
4, Commission the Virtual Machines
注意，此时maas node节点的状态是New状态， 需点击"Commission Node"按钮(将变成Commissioning状态), 最后变成"Ready"状态。
只有Ready状态的节点才可以分配给Juju使用， 注意此时还是无法登录的，用户名和密码被禁用掉了。只有等使用juju部署服务被分配给某一用户之后，才将用户的ssh publich key注入到镜像中，这时候才可以通过ssh ubuntu@<ip>来登录maas node(即deploy状态才可以ssh)。注意：Ready状态的maas node应该是stop的，我们不应该人工启动，而应该交给maas来控制启动。
点击"Acquire and start node“按钮变成deploy状态后的maas node如下图所示：
5,新建两个tag, 并将第一个虚机打上bootstrap tag, 第二个虚机打上compute tag
maas myprofile tags new name=bootstrap
maas myprofile tags new name=compute
maas myprofile tag update-nodes bootstrap add=`maas myprofile nodes list hostname=maas-controller |grep system_id | cut -d \" -f 4`
maas myprofile tag update-nodes compute add=`maas myprofile nodes list hostname=maas-compute |grep system_id | cut -d \" -f 4`
maas myprofile tag nodes bootstrap
maas myprofile tag nodes compute
Setup juju for use with MAAS env
在maas虚机上继续安装juju
sudo apt-get install -y software-properties-common
sudo add-apt-repository ppa:juju/stable
sudo apt-get update && sudo apt-get install -y juju juju-deployer
juju generate-config && juju switch maas
then using the following content to update maas section of ~/.juju/environments.yaml file .
其中maas-oauth来自http://192.168.100.3/MAAS/account/prefs/界面，或者使用命令”sudo maas-region-admin apikey --username=admin”查看。
maas:
type: maas
maas-server: 'http://192.168.100.3/MAAS/'
maas-oauth: 'XFRrvYsxvag3DkbsFD:KBTHjWW4uEPKCYwBh3:5LNnXaHGPdXGhUppPK2Z4mPbGNaW5nVh'
authorized-keys-path: ~/.ssh/id_rsa.pub
admin-secret: password
default-series: trusty
运行juju bootstrap在打了bootstrap tag的虚机上安装并运行juju agent，如果出错，多半是因为域名问题，请检查maas-dns, 通过juju --debug status可获得信息。
juju bootstrap --upload-tools --show-log --debug --constraints tags=bootstrap
juju set-constraints tags= #上句执行后执行这句避免给接下来的机器打乱了标签
注意：此时IP已经使用了MAAS_STATIC_RANGE_START， 即为192.168.100.100.
hua@hua-ThinkPad-T440p:/bak/images$ ssh ubuntu@192.168.100.100
ubuntu@maas-node-1:~$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 192.168.100.3
search maas
maas server本身也应该使用自己提供的dns服务，这样在juju --debug status的时候才有可能解析到安装在maas node上的juju服务。
可在maas node上使用命令”sudo tailf /var/log/cloud-init-output.log“监控maas server通过ssh连进来在安装juju-agent charm时做了什么事情。最终在juju bootstrap maas node上启动下下列进程：
ubuntu@maas-node-0:~$ ps -ef|grep juju
root 2098 1 0 03:38 ? 00:00:00 dhclient -1 -v -pf /run/dhclient.juju-br0.pid -lf /var/lib/dhcp/dhclient.juju-br0.leases juju-br0

root 11850 1 2 03:46 ? 00:00:01 /var/lib/juju/tools/machine-0/jujud machine --data-dir /var/lib/juju --machine-id 0 --debug
并使用juju status命令查看状态如下（调试时可使用juju --debug status)：
ubuntu@maas:~$ juju status
environment: maas
machines:
"0":
agent-state: started
agent-version: 1.23.3.1
dns-name: maas-node-0.maas

juju bootstrap --to <hostname> # bootstrap the state-server on a specific machine
juju add-machine <hostname> # add existing MAAS-controlled machines to the juju environment
There exist a tool do the same thing, see: https://github.com/niedbalski/maasive
-------------------------------------------- 分隔线 ---------------------------------------------------------------
下载juju charms到maas server上，
sudo apt-get install -y charm-tools
mkdir -pv ~/charms/trusty
cd ~/charms/trusty/
for CHARM in \

部署juju-gui, 其中--to=0是指已经启动的第1个即安装juju agent的那个maas node.
cd ~/charms
juju deploy --to=0 local:trusty/juju-gui
juju expose juju-gui
ubuntu@maas:~/charms$ juju status juju-gui
environment: maas
machines:
"0":
agent-state: started
agent-version: 1.23.3.1
dns-name: maas-node-0.maas

agent-version: 1.23.3.1
machine: "0"
open-ports:
- 80/tcp

public-address: maas-node-0.maas
然后通过访问http://maas-node-0.maas即可访问juju-gui的界面，也可以将域名换成IP.
ubuntu@maas:~/charms$ juju ssh juju-gui/0
部署ntp charm
ubuntu@maas:~/charms$ cat ~/openstack-ntpmaster.yaml
ntpmaster:
source: LOCAL
上面的yaml文件怎么写可以通过charm-info命令查看帮助
ubuntu@maas:~/charms$ charm-info ntpmaster
然后部署：
cd ~/charms/
# clear any Juju constraints, 确保它部署在第一个节点上
juju set-constraints tags=
# deploy the NTP server:
juju deploy --to 0 --config ~/openstack-ntpmaster.yaml local:trusty/ntpmaster
4. watch the progress of the charm deployment
juju debug-log
同理方法部署neutron, 因为两个虚机都有两个网卡，所以有：ext-port: 'eth1'.
juju set-constraints tags=
juju deploy --to 0 --config ~/openstack-neutron.yaml local:trusty/quantum-gateway
ubuntu@maas:~/charms$ cat ~/openstack-neutron.yaml
quantum-gateway:
openstack-origin: distro
ext-port: 'eth1'
instance-mtu: 1400
同理方法部署计算节点, 注意，此时没有加--to 0，这样会找maas要一个新节点部署（这时候第2个虚机会启动）
juju set-constraints tags=
juju deploy --constraints tags=compute --config ~/openstack-compute.yaml local:trusty/nova-compute -n 1
ubuntu@maas:~/charms$ cat ~/openstack-compute.yaml
nova-compute:
openstack-origin: distro
新节点部署后使用juju status看到的状态是：
"2":
agent-state: pending
dns-name: maas-node-1.maas
instance-id: /MAAS/api/1.0/nodes/node-c0908402-0550-11e5-aeec-525400a843f2/
series: trusty
hardware: arch=amd64 cpu-cores=1 mem=2048M tags=compute
同理方法部署mysql, 将mysql通过--to=0(其中是0还是其他的什么通过juju status查看，另外若是容器可加--to=lxc:2)部署在第1个节点上,
juju deploy --to=0 local:trusty/mysql
同理方法部署keystone到第1个节点
juju deploy --to=0 --config ~/openstack-keystone.yaml local:trusty/keystone
ubuntu@maas:~/charms$ cat ~/openstack-keystone.yaml
keystone:
openstack-origin: distro
admin-password: password
同理方法将rabbitmq部署到第1个节点
juju deploy --to=0 local:trusty/rabbitmq-server
部署controller到第1个节点
juju deploy --to=0 --config ~/openstack-controller.yaml local:trusty/nova-cloud-controller
ubuntu@maas:~/charms$ cat ~/openstack-controller.yaml
nova-cloud-controller:
openstack-origin: distro
network-manager: 'Neutron'
quantum-security-groups: "yes"
console-access-protocol: spic
部署glance服务到第1个节点
juju deploy --to=0 --config ~/openstack-glance.yaml local:trusty/glance
ubuntu@maas:~/charms$ cat ~/openstack-glance.yaml
glance:
openstack-origin: distro
部署ntp client, ntp server是安装在maas-node-0.maas上，
juju deploy --config ~/openstack-ntp.yaml local:trusty/ntp
ubuntu@maas:~/charms$ cat ~/openstack-ntp.yaml
ntp:
source: maas-node-0.maas
ntp charm是一个子charm, 会附着在maas-node-0.maas与maas-node-1.maas上
juju add-relation quantum-gateway ntp
juju add-relation nova-compute ntp
添加其他关系，因为只有两个虚机，一个虚机安装juju agent及openstack除nova-compute以外的所有服务，一个虚机安装nova-coumpute，机器性能有限，所以我们没有安装horizon, cinder, swift这些组件，仅是一个最小安装。
添加关系之前先用“juju status |grep agent-state”命令确保每一个charm都是installed状态。
juju add-relation keystone mysql
juju add-relation nova-cloud-controller mysql
juju add-relation nova-cloud-controller keystone
juju add-relation nova-cloud-controller rabbitmq-server
juju add-relation nova-cloud-controller glance
juju add-relation nova-cloud-controller quantum-gateway
juju add-relation nova-compute:shared-db mysql

juju add-relation nova-compute glance
juju add-relation glance mysql
juju add-relation glance keystone
juju add-relation quantum-gateway mysql
juju add-relation quantum-gateway:amqp rabbitmq-server:amqp
然后使用juju status命令查看状态，如果有错，可以使用juju resolved -r keystone/0重新部署。
部署bundle
juju-deployer -c OPENSTACK_BUNDLE
watch juju status --format=tabular
使用openstack
a, novarc文件如下：
#!/bin/bash

export OS_AUTH_URL=http://`juju-deployer -f keystone`:5000/v2.0/
export OS_USERNAME=proj01user
export OS_PASSWORD=openstack
export OS_TENANT_NAME=Project01
e, 定义key pair
nova keypair-add --pub_key ~/.ssh/id_rsa.pub mykey
f, 定义默认的security group允许ssh与icmp
nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
g, 配置tenant router, 即虚机所使用的网络
neutron net-create Project01_Network
neutron subnet-create --name Project01_Subnet --allocation-pool \
start=10.0.0.10,end=10.0.0.199 \
--gateway=10.0.0.1 --enable_dhcp=True \
--dns-nameserver 192.168.100.3 --dns-nameserver 8.8.8.8 \
Project01_Network PRIVATE_SUBNET_ID
neutron router-create Project01_Public
neutron router-gateway-set Project01_Public Public_Network
neutron router-interface-add Project01_Public Project01_Subnet
h, 创建虚机
nova flavor-create --is-public True m1.smaller auto 512 5 1
nova aggregate-create SSD nova
nova aggregate-add-host SSD compute01
nova aggregate-add-host SSD compute03
nova aggregate-set-metadata SSD ssd=true
nova flavor-key ssd.smaller set ssd=true
nova flavor-show ssd.smaller
nova boot demo1 --flavor m1.smaller --image 1 --key-name mykey
i, 使用floating ip
nova floating-ip-create Public_Network
nova floating-ip-associate VM_NAME FLOATING_IP_ADDR
Juju Bundle
多个charm在一个机器里可能会有冲突，要在一个机器里最好也是使用容器隔离, 其余两个不能运行在容器的neutron-gateway（因为netlink/iscsc不能运行在容器）和nova-compute（因为ovs不能运行在容器），它们俩只能一个一个虚机了。共得3台虚机。但容器用的是lxcbr0, eth0必须在它里头才可能和另两个虚机网络通，针对这个问题，maas provider与local provider的处理方法不一样：
1, maas provider, 通过sudo cat /var/lib/juju/containers/juju-trusty-lxc-template/lxc.conf配置lxc.network.link = juju-br0， 而非lxcbr0, 请看例子:
juju deploy --to 0 local:trusty/juju-gui
juju deploy --to lxc:0 local:trusty/mysql
juju deploy --to lxc:0 local:trusty/keystone
juju deploy --to lxc:0 nova-cloud-controller
juju deploy --to lxc:0 local:trusty/glance
juju deploy --to lxc:0 local:trusty/rabbitmq-server
juju deploy --to lxc:0 local:trusty/openstack-dashboard
juju deploy --to lxc:0 local:trusty/cinder
juju ssh 192.168.100.100 lxc-ls --fancy
juju deploy --constraints tags=compute local:trusty/nova-compute
然后 等 所以状态juju status |grep agent-state变成installed之后再执行下列命令
juju add-relation mysql keystone
juju add-relation nova-cloud-controller mysql
juju add-relation nova-cloud-controller rabbitmq-server
juju add-relation nova-cloud-controller glance
juju add-relation nova-cloud-controller keystone
juju add-relation nova-compute nova-cloud-controller
juju add-relation nova-compute mysql
juju add-relation nova-compute rabbitmq-server:amqp
juju add-relation nova-compute glance
juju add-relation glance mysql
juju add-relation glance keystone
juju add-relation glance cinder
juju add-relation mysql cinder
juju add-relation cinder rabbitmq-server
juju add-relation cinder nova-cloud-controller
juju add-relation cinder keystone
juju add-relation openstack-dashboard keystone
juju set keystone admin-password="password"
2, maas local, lp:charms/ubuntu用来部署一台虚机并已经配置好了将eth0加到了lxcbr0，new-lxc-network: False用于指定使用已经配置好的lxcbr0, 请看例子。

或者分解动作如下, 一步步有利于调试：
# 部署一个虚机，内存设置大一点, 修改~/.juju/environments.yaml文件中的下列内容能让local provider部署从容器改为部署虚机
local:
type: local
lxc-clone: true
container: kvm
cat ubuntu-charm.yaml
ubuntu:
branch: cs:trusty/ubuntu-3 # 部署ubuntu charm不成功时得检查这个源对不对，如果不对就直接"juju deploy --constraints "mem=5G root-disk=12G" ubuntu"之后再人工去修改网络吧
series: trusty
constraints: "mem=2G root-disk=10G"
num_units: 1
new-lxc-network: False
juju deploy --constraints "mem=5G root-disk=12G" local:trusty/ubuntu --config ubuntu-charm.yaml
# juju set ubuntu new-lxc-network=False
# 用juju status确定该虚机的ID=1，部署其他服务到该虚机的容器里，容器使用的lxcbr0网桥上有eth0和其他虚机相通.
ubuntu charm通过new-lxc-network=False来让容器使用已存在的lxcbr0, 人工设置/etc/network/interfaces.d/lxcbr0.cfg内容如下,
且删除sudo rm -rf /etc/network/interfaces.d/eth0.cfg， 最后重启网络让其生效（最好不要重启机器, 通过“sudo ifup lxcbr0”命令
在ubuntu server中重启网络有一个bug，只能是针对接口进行ifdown与ifup
sudo ifup lxcbr0
https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1301015
auto eth0
iface eth0 inet manual
auto lxcbr0
iface lxcbr0 inet dhcp
bridge_ports eth0
juju deploy --to lxc:1 --constraints mem=1G local:trusty/mysql
对于容器，要先执行/var/lib/juju/contaners/[container-name]/cloud-init里的脚本，该脚本在创建了容器之后才会创建日志文件/var/log/juju/[contailer-name].log, 容器也通过下列命令查看：
juju ssh ubuntu/0 sudo lxc-ls --fancy
所有过程都特别慢，是否出错可以通过上述日志查看。
juju deploy --to lxc:1 local:trusty/rabbitmq-server
juju deploy --to lxc:1 local:trusty/keystone
juju deploy --to lxc:1 nova-cloud-controller
juju deploy --to lxc:1 local:trusty/glance
# 部署其他两个虚机安装nova-compute与neutron-gateway

在安装maas和juju的过程中填过的坑总结:
1, maas的安装包把postgresql的依赖做进去了，它又没有自动安装postgresql，也没有自动建库，所以报错，但报出的错与我说的可不一样
2, 在界面将一个网卡设置成“dhcp与dns”时报内部服务器错误，没有更多信息了，刚开始以为可以不用dns，后来juju老出错，才发现dns是必选项，然后下定决定解决dns的问题，然后研究bind9，发现是一个bug，需要touch一个空目录
3, 有时候创建了maas node，但在界面中不显示，重启三个maas服务可以解决问题, 也可能是因为我的机器慢要等的时候长
4, 然后就是创建的maas node无法登录的问题，原来是maas node在使用juju部署服务之前本来就是不能登录的，刚开始不知道啊
5, 然后就是研究虚机里的容器与虚机的网络问题，发现maas provider与local provider不一样，maas provider用的是juju-br0这个网桥
6, ERROR charm upload failed: 400 ({"Error":"error processing file upload: write /tmp/charm248900750: no space left on device"})
安装MAAS可以采用maas-deployer更快捷的方式，它会自动在物理机上创建maas虚机：
export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
locale-gen en_US.UTF-8
sudo dpkg-reconfigure locales
sudo apt-get install maas-cli maas-deployer
cp /usr/share/maas-deployer/examples/deployment.yaml ~
maas-deployer -c deployment.yaml --debug
maas-deployer -c deployment.yaml --debug --use-existing
sudo maas maas nodes list
#sudo maas maas vlans create 0 name="API Network" vid=318
#sudo maas maas subnets create name="API Network" fabric=0 vlan=318 space=0 cidr="<cidr>" gateway_ip='<gw>'
http://192.168.122.2/MAAS ubuntu/ubuntu
如何往MAAS里添加物理节点
maas maas nodes new\
autodetect_nodegroup=yes\
hostname=<NEW_HOSTNAME>\
architecture=amd64/generic\
tags=<TAGNAME:compute>\
mac_addresses=<MAC_ADDRESS_FOR_PXE>\
power_type=ipmi\
power_parameters_power_driver=LAN_2_0\
power_parameters_power_address=<IPMI_IP_ADDRESS>\
power_parameters_power_user=<IPMI_USERNAME>\
power_parameters_power_pass=<IPMI_PASSWORD>
如何查看支持IPMI的物理节点
maas maas maas set-config name=kernel_opts value='console=tty0console=ttyS1,115200'
sudo apt-get install freeipmi-tools
ipmiconsole -h<IPMI_HOST> -u<IPMI_USER> -P
增加的节点在Juju中如何使用
maas maas nodeclaim-sticky-ip-address\
<SYSTEM_ID>\
requested_address=<IP_ADDRESS_TO_CLAIM>\
mac_address=<MAC_ADDRESS_FOR_THE_IP>
juju add-unit nodes-compute
juju add-unit --to<MACHINE_NUMBER> ceph-osd
