Ubuntu14.04下安装DevStack

虚拟机中的网络配置 NET8 为nat net2 为host-only

虚拟机网络配置

# The primary network interface vmnet  nat type

auto eth0

iface eth0 inet static

        address 192.168.30.80

        netmask 255.255.255.0

        network 192.168.30.0

        broadcast 192.168.30.255

        gateway 192.168.30.2

        # dns-* options are implemented by the resolvconf package, if installed

        dns-nameservers 114.114.114.114

# vmnet 2 nat type openstack 内部网络

auto eth2

iface eth2 inet manual

trouble shooting

　　　　类似 xxxx is not in global-requirements.txt 问题,比如

　　　　2015-04-25 08:34:28.440 | 'wsgiref' is not in global-requirements.txt

　　　　解决方法：

　　　　找到openstack requirement project in https://github.com/openstack/requirements/tree/master

　　　　将 branch 切换到对应的 branch ，比如juno。打开global-requirements.txt 文件，搜索wsgiref 可以看到wsgiref>=0.1.2

　　　　将这一行加到/opt/stack/requirements/global-requirements.txt

　　　　echo "wsgiref>=0.1.2" >> /opt/stack/requirements/global-requirements.txt

　　　　引起问题的原因，因为源码是git 的juno branch 但是运行devstak /stack.sh的时候，会自动去git master的requirements 项目，branch 不匹配。

下载DevStack 这里的devstack 一定要和 git 出来的openstack 源代码的branch 一样，不然会出错。

git clone https://github.com/openstack-dev/devstack.git -b stable/kilo

更改pip源

#vim ~/.pip/pip.conf

[global]
timeout=180
index-url = http://pypi.douban.com/simple

更改devstack/local.conf
stackrc文件中包含了各个服务的配置介绍，需要安装哪些服务，参照其中的配置进行修改。
# Sample ``local.conf`` for user-configurable variables in ``stack.sh``

# NOTE: Copy this file to the root DevStack directory for it to work properly.

# ``local.conf`` is a user-maintained settings file that is sourced from ``stackrc``.
# This gives it the ability to override any variables set in ``stackrc``.
# Also, most of the settings in ``stack.sh`` are written to only be set if no
# value has already been set; this lets ``local.conf`` effectively override the
# default values.

# This is a collection of some of the settings we have found to be useful
# in our DevStack development environments. Additional settings are described
# in http://devstack.org/local.conf.html
# These should be considered as samples and are unsupported DevStack code.

# The ``localrc`` section replaces the old ``localrc`` configuration file.
# Note that if ``localrc`` is present it will be used in favor of this section.
[[local|localrc]]
VERBOSE=True
NEUTRON_CREATE_INITIAL_NETWORKS=False
disable_service n-net
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
enable_service q-metering

Q_L3_ENABLED=True
PUBLIC_INTERFACE=eth1
OVS_PHYSICAL_BRIDGE=br-ex
PUBLIC_BRIDGE=br-ex
OVS_BRIDGE_MAPPINGS=public:br-ex

#open v switch
Q_USE_SECGROUP=True
ENABLE_TENANT_VLANS=True
TENANT_VLAN_RANGE=1000:1999
PHYSICAL_NETWORK=default

# Minimal Contents
# ----------------

# While ``stack.sh`` is happy to run without ``localrc``, devlife is better when
# there are a few minimal variables set:

# If the ``SERVICE_TOKEN`` and ``*_PASSWORD`` variables are not set
# here you will be prompted to enter values for them by ``stack.sh``
# and they will be added to ``local.conf``.
SERVICE_TOKEN=azertytoken
ADMIN_PASSWORD=secrete
MYSQL_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD

# ``HOST_IP`` should be set manually for best results if the NIC configuration
# of the host is unusual, i.e. ``eth1`` has the default route but ``eth0`` is the
# public interface. It is auto-detected in ``stack.sh`` but often is indeterminate
# on later runs due to the IP moving from an Ethernet interface to a bridge on
# the host. Setting it here also makes it available for ``openrc`` to include
# when setting ``OS_AUTH_URL``.
# ``HOST_IP`` is not set by default.
HOST_IP=192.168.30.80

# Logging
# -------

# By default ``stack.sh`` output only goes to the terminal where it runs. It can
# be configured to additionally log to a file by setting ``LOGFILE`` to the full
# path of the destination log file. A timestamp will be appended to the given name.
LOGFILE=$DEST/logs/stack.sh.log

# Old log files are automatically removed after 7 days to keep things neat. Change
# the number of days by setting ``LOGDAYS``.
LOGDAYS=2

# Nova logs will be colorized if ``SYSLOG`` is not set; turn this off by setting
# ``LOG_COLOR`` false.
#LOG_COLOR=False

# Using milestone-proposed branches
# ---------------------------------

# Uncomment these to grab the milestone-proposed branches from the repos:
#CINDER_BRANCH=milestone-proposed
#GLANCE_BRANCH=milestone-proposed
#HORIZON_BRANCH=milestone-proposed
#KEYSTONE_BRANCH=milestone-proposed
#KEYSTONECLIENT_BRANCH=milestone-proposed
#NOVA_BRANCH=milestone-proposed
#NOVACLIENT_BRANCH=milestone-proposed
#NEUTRON_BRANCH=milestone-proposed
#SWIFT_BRANCH=milestone-proposed

# Swift
# -----

# Swift is now used as the back-end for the S3-like object store. If Nova's
# objectstore (``n-obj`` in ``ENABLED_SERVICES``) is enabled, it will NOT
# run if Swift is enabled. Setting the hash value is required and you will
# be prompted for it if Swift is enabled so just set it to something already:
SWIFT_HASH=66a3d6b56c1f479c8b4e70ab5c2000f5

# For development purposes the default of 3 replicas is usually not required.
# Set this to 1 to save some resources:
SWIFT_REPLICAS=1

# The data for Swift is stored by default in (``$DEST/data/swift``),
# or (``$DATA_DIR/swift``) if ``DATA_DIR`` has been set, and can be
# moved by setting ``SWIFT_DATA_DIR``. The directory will be created
# if it does not exist.
SWIFT_DATA_DIR=$DEST/data

# Tempest
# -------

# Install the tempest test suite
enable_service tempest
由于网络问题，手动下载OpenStack组件源码

sudo git clone https://github.com/kanaka/noVNC.git /opt/stack/noVNC

创建stack用户/组

#cd devstack/tools

#sudo ./devstack/tools/create-stack-user.sh

修改/opt/stack用户/组
```
#chown -R stack:stack /opt/stack
```
将 stack 赋予root 权限

　　sudo nano /etc/sudoers
　　在root 下添加
　　stack ALL=(ALL:ALL) NOPASSWD:ALL

　　将 devstac 的owner 设置为 stack

sudo chown -R stack:stack devstack

执行stack.sh

　　必须在devstack 执行，否则会遇到会遇到mktemp -d ----xxxxxx 权限不够的错误。因为当前路径对stack 用户来说，很可能没有写权限

#su stack

#./stack.sh

 安装完成之后
执行 sudo ovs-vsctl add-port br-ex eth2， 将eth2 借口加入ovs 虚拟交换机
