前言
本次使用devstack实现 all-in-one 模式的安装，Openstack版本为Queen。devstack一键安装，学习成本较低，适合入门。

- 软件：Parallels Desktop14破解版 网盘下载 密码:oei9
- 操作系统：ubuntu16.04（server版）
安装ubuntu虚机
下载镜像：
http://mirrors.aliyun.com/ubuntu-releases/16.04/
使用Parallels Desktop安装虚机
虚机配置为：4C、4GB、60GB
虚机内存越大越好，推荐8G以上。由于宿主机Mac的内存只有8GB，这里虚机只分了4GB。
安装过程略……
配置国内源
若网络能翻墙，可以跳过此步骤。
配置Ubuntu apt source源
执行下面命令：
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
sudo vim /etc/apt/sources.list在编辑界面，删除原来的内容，输入一下内容：

# deb-src http://security.ubuntu.com/ubuntu xenial-security multiverse最后执行下面的命令完成配置：
sudo apt update配置pip源
OpenStack大部分项目是python项目，安装过程中要下载大量python包，为了更顺畅的安装，需要修改pip源。
mkdir ~/.pip
vim ~/.pip/pip.confpip.conf的内容如下：
[global]
trusted-host=mirrors.aliyun.com
index-url=http://mirrors.aliyun.com/pypi/simple同时接着修改下面的文件，使其和~/.pip/pip.conf的内容一致：
sudo mkdir /root/.pip
sudo vim /root/.pip/pip.conf配置stack用户并下载devstack
部署的脚本要求是拥有 root 权限的非 root 用户，依次执行下面的命令：
sudo useradd -s /bin/bash -d /opt/stack -m stack
echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
sudo su - stack
cd /opt/stack
git clone https://git.openstack.org/openstack-dev/devstack
cd devstack
git checkout remotes/origin/stable/queens
git checkout -b queens配置devstack local.conf
进入devstack目录，执行下面的命令：
cp samples/local.conf ./
vim local.conflocal.conf文件内容如下：
[[local|localrc]]
HOST_IP=your host ip
# Minimal Contents
# ----------------
# While ``stack.sh`` is happy to run without ``localrc``, devlife is better when
# there are a few minimal variables set:
# If the ``*_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``.
ADMIN_PASSWORD=nomoresecret
DATABASE_PASSWORD=stackdb
RABBIT_PASSWORD=stackqueue
SERVICE_PASSWORD=$ADMIN_PASSWORD
# ``HOST_IP`` and ``HOST_IPV6`` should be set manually for best results if
# the NIC configuration of the host is unusual, i.e. ``eth1`` has the default
# route but ``eth0`` is the public interface. They are auto-detected in
# ``stack.sh`` but often is indeterminate on later runs due to the IP moving
# from an Ethernet interface to a bridge on the host. Setting it here also
# makes it available for ``openrc`` to include when setting ``OS_AUTH_URL``.
# Neither is set by default.
#HOST_IPV6=2001:db8::7
# Logging
# -------
# By default ``stack.sh`` output only goes to the terminal where it runs. It can
# be configured to additionally log to a file by setting ``LOGFILE`` to the full
# path of the destination log file. A timestamp will be appended to the given name.
LOGFILE=$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
# Using git versions of clients
# -----------------------------
# By default clients are installed from pip. See LIBS_FROM_GIT in
# stackrc for details on getting clients from specific branches or
# revisions. e.g.
# LIBS_FROM_GIT="python-ironicclient"
# IRONICCLIENT_BRANCH=refs/changes/44/2.../1
# Swift
# -----
# Swift is now used as the back-end for the S3-like object store. 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
API_WORKERS=1

完成上面的步骤后，开始执行安装命令：
./stack.sh安装过程一般需要2个小时左右，主要取决于网速。直到出现以下内容，则表示安装成功：
