一、DevStack介绍
Devstack目前是支持Ubuntu16.04和CentOS 7,而且Devstack官方建议使用Ubuntu16.04,所以我们使用Ubuntu 16.04进行安装。
默认无论是Devstack和OpenStack,都是采用Master的代码进行安装,这样经常会出现,今天安装成功,明天失败,代码时刻在变化。所以我们不仅仅要指定OpenStack的版本,还需要指定Devstack的版本,才能提供安装成功的概率。
二、DevStack的安装
1、环境准备
我使用的操作系统为Ubuntu 16.04的版本,默认的软件包源是国外的,速度相对来说比较慢,所以我们修改文件/etc/apt/sources.list,使用如下命令更改:
sed -i 's/us.archive.ubuntu.com/cn.archive.ubuntu.com/g' /etc/apt/sources.list
sed -i 's/security.ubuntu.com/cn.archive.ubuntu.com/g' /etc/apt/sources.list
更新一下源。
apt-get update
2、下载devstack
安装devstack痛苦的其中一个原因,是OpenStack代码,都需要从github下载,这样由于网络的原因,经常导致各种错误,简直让人崩溃,各种错误,目前国内已经提供了完整的OpenStack的github的mirror:http://git.trystack.cn,这样Devstack成功概率会大大提高。
另外devstack还会下载image,下载的过程也是非常缓慢。trystack也提供大家常用的image下载:http://images.trystack.cn。
目前官方github上面保留着三个稳定的版本,我们这边安装queens版。
mkdir -p /opt/stack/ && cd /opt/stack
apt-get install git
git clone http://git.trystack.cn/openstack-dev/devstack.git -b stable/queens
3、创建stack用户
目前Devstack脚本已经不支持直接使用root身份运行,你需要创建stack用户运行。
cd devstack/tools/
./create-stack-user.sh
修改devstack目录权限,让stack用户可以运行。
cd ../..
chown -R stack:stack /opt/stack
4、配置pip源
OpenStack很多组件需要从pip源下载,默认是国外的源,我们需要设置为国内的源,以便可以快速的进行配置,在root和stack的加目录下面都配置一下。
首先分别在家目录下面都创建.pip的目录,然后在目录下面创建文件pip.conf,内容如下:
su stack
mkdir .pip
cat >> .pip/pip.conf <<EOF
[global]
trusted-host = pypi.douban.com
index-url = http://pypi.douban.com/simple
EOF
5、配置文件
cd devstack
cp samples/local.conf .
对文件local.conf进行简单修改,如下内容:
[[local|localrc]]
ADMIN_PASSWORD=secret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
LOGFILE=$DEST/logs/stack.sh.log
LOGDAYS=2
SWIFT_HASH=66a3d6b56c1f479c8b4e70ab5c2000f5
SWIFT_REPLICAS=1
SWIFT_DATA_DIR=$DEST/data
# use TryStack git mirror
GIT_BASE=http://git.trystack.cn
NOVNC_REPO=http://git.trystack.cn/kanaka/noVNC.git
SPICE_REPO=http://git.trystack.cn/git/spice/spice-html5.git
6、安装
中途可能会出现多次错误,大部分都是因为网络的原因,重复运行命令即可。
./stack.sh
三、验证
经过长时间的等待之后,根据网络状态,大约1个小时的时间,出现下面的界面即可是安装完成。

-
Set FLOATING_RANGE to a range not used on the local network, i.e. 192.168.1.224/27. This configures IP addresses ending in 225-254 to be used as floating IPs.
-
Set FIXED_RANGE and FIXED_NETWORK_SIZE to configure the internal address space used by the instances.
-
Set FLAT_INTERFACE to the Ethernet interface that connects the host to your local network. This is the interface that should be configured with the static IP address mentioned above.
-
Set the administrative password. This password is used for the admin and demo accounts set up as OpenStack users.
-
Set the MySQL administrative password. The default here is a random hex string which is inconvenient if you need to look at the database directly for anything.
-
Set the RabbitMQ password.
-
Set the service password. This is used by the OpenStack services (Nova, Glance, etc) to authenticate with Keystone.
