在ubuntu16.04上用devstack一键部署openstack（1）教程

sudo apt-get install git

sudo apt-get install vim
这个电脑因为连 的是无线，配置ip的时候不能如下直接配
vim /etc/network/interfaces
auto ens33
iface ens33 inet static
address 192.168.31.25
netmask 255.255.255.0
gateway 192.168.31.1
dns-nameserver 192.168.31.1
应该点击右上角的上网标志然后点击编辑连接，点击你连接的wifi点击编辑，点击ipv4改成手动，然后手动添加ip地址192.168.31.25 255.255.255.0 192.168.31.1 dns 192.168.31.1,如果不知道dns是多少时，配置前可以右击右上角的上网标志也就是wifi标志，点击连接信息的dns

安装pip并修改pip源：
apt-get install python-pip
mkdir ~/.pip
vi ~/.pip/pip.conf
添加
[global]
index-url = http://pypi.douban.com/simple/
trusted-host = pypi.douban.com

cd /home

git clone http://git.trystack.cn/openstack-dev/devstack.git -b stable/ocata

cd /home/devstack/tools

创建stack用户
./create-stack-user.sh或者sudo useradd -s /bin/bash -d /opt/stack -m stack

echo 'stack ALL=(ALL) NOPASSWD: ALL' | sudo tee /etc/sudoers.d/stack

sudo chown -R stack:stack /home/devstack

chmod 777 /dev/pts/0

切换到stack用户并修改pip源：

sudo su - stack

mkdir ~/.pip
vi ~/.pip/pip.conf
添加
[global]
index-url = http://pypi.douban.com/simple/
trusted-host = pypi.douban.com
设置Devstack配置文件：
cd /home/devstack

vim local.conf

打开文件输入以下内容并设置密码

开始部署：
./stack.sh
若安装失败，则执行./unstack.sh脚本和./clean.sh脚本，并重复上一步骤
出现的错误
1.
E: Problem executing scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w /var/cache/app-info -a -e /usr/bin/appstreamcli; then appstreamcli refresh > /dev/null; fi'
E: Sub-process returned an error code
解决方法：

sudo apt-get remove libappstream3
or
sudo apt remove libappstream3
再进行update
sudo apt-get update

2.
在ubuntu系统的termial下，用apt-get install 安装软件的时候，如果在未完成下载的情况下将terminal close。此时 apt-get进程可能没有结束。结果，如果再次运行apt-get install 命令安装如今，可能会发生下面的提示：
无法获得锁 /var/lib/dpkg/lock - open (11: 资源暂时不可用)
无法锁定管理目录(/var/lib/dpkg/)，是否有其他进程正占用它？

解决办法如下：
1。终端输入 ps aux ，列出进程。找到含有apt-get的进程，直接sudo kill PID。

2。强制解锁,命令
sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock

3.

字符集的问题，在文件前加两句话：

reload(sys)
sys.setdefaultencoding( "utf-8" )

解决
\#pip --default-timeout=100 install -U pip

修改~/.pip/pip.conf为当前用户配置．
如:stack@ztf-virtual-machine:/etc$ sudo vim pip.conf

windows下pip配置文件为 C:\Users\xx\pip\pip.ini ，没有就新建．

[global]
index-url = http://pypi.douban.com/simple
trusted-host = pypi.douban.com

5. File "/usr/lib/python2.7/dist-packages/setuptools/command/easy\_install.py", line 657, in easy\_install

You are using pip version 9.0.3, however version 18.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
解决：
sudo pip install --upgrade pip
