devstack安装和测试

问题导读：

1.devstack安装之前需要做哪些准备？

2.如何下载源码？

3.通过什么命令可以运行运行Devstack？

采用豆瓣的pypi进行安装。

目前Devstack脚本已经支持Centos 6.5，那么你可以选择是在Ubuntu 12.04或者CentOS 6.5下来安装，步骤基本都是一样。就是一个git命令安装的区别.

最小化安装CentOS 6.5，我是关闭了selinux，不关闭应该也是可以的。，用root账号登陆。

对于CentOS6.5来说，devstack脚本会添加EPEL和RDO源。

2014年6月6日：文档更新，已经可以支持siwft和trove。不过安装过程，你可能会遇到cliff的bughttps://review.openstack.org/#/c/95916/，如果你遇到horizon无法启动，那么你就去 /etc/httpd/conf.d/ 里把那个配置文件后缀disable去掉就ok。还有就是安装过程，由于启用了heat，会下载一个heat的镜像，会导致安装过程很慢，可以考虑修改stackrc文件，不让下载。另外csdn的git源，也应该没法使用，因为项目太多没有同步了。

修复cilff的bug，估计上游很快就会merge

cd /opt/stack/cliff/
git fetch https://review.openstack.org/openstack/cliff refs/changes/16/95916/4 && git checkout FETCH_HEAD
复制代码

准备环境

设置使用豆瓣pypi源

mkdir $HOME/.pip
vi $HOME/.pip/pip.conf
复制代码

输入下面内容

[global]
index-url = http://pypi.douban.com/simple/
复制代码

简单的做法

mkdir /root/.pip
cat >/root/.pip/pip.conf <<EOF
[global]
index-url = http://pypi.douban.com/simple/
EOF
复制代码

安装git

yum -y install git
复制代码

设置iptables

我发现目前版本，devstack不会去打开iptables的80端口，所以在运行脚本前，我设置一下iptables，编辑 /etc/sysconfig/iptables，添加一行，打开80端口。

准备Devstack

下载代码

cd /home
git clone https://github.com/openstack-dev/devstack.git
复制代码

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 /home/devstack/tools/
./create-stack-user.sh
复制代码

修改devstack目录权限,让stack用户可以运行

chown -R stack:stack /home/devstack
复制代码

切换的stack用户下

su stack
cd /home/devstack
复制代码

devstack运行时候，检测到操作系统是CentOS，会额外添加RDO和EPEL源，由于我的os已经配置好，我需要把添加的步骤注释掉，修改一下 stack.sh 脚本就可以。

进入devstack目录下，创建localrc 文件，默认devstack会创建一个stack-volumes，用文件来模拟，我修改成cinder-volumes。

你还需要修改你的host ip. 我的localrc

复制代码

运行Devstack

记住，我们是使用stack用户运行的。

cd /home/devstack
./stack.sh
复制代码

默认Devstack创建 admin和demo两个用户，通过设置环境变量可以进行操作

admin

source openrc admin admin
复制代码

demo

source openrc demo demo
复制代码

附录

如果你希望用物理的卷代替文件模拟的volume。Devstack会检测是否存在一个stack-volumes 的卷，如果存在就使用，不存在就用文件模拟。

pvcreate /dev/sdc
vgcreate stack-volumes /dev/sdc
复制代码

说的很不错，支持楼主

这篇应该是chenshake陈沙克的文章，写得很好，能注明出处自然更好了。

[/mw_shl_code]就是这句No package python-mox available.报错
我的操作系统是Centos6.5
在执行stack.sh时已经安装了epel和rdo源了
python-mox这个包应该在哪获取

可能下载不了，原因你懂的
[mw_shl_code=bash,true]yum install -y python-mox.noarch[/mw_shl_code]

pymox是一套用于python代码unit test的框架. 官方链接如下:

那怎么解决的呢

如何访问dashboard？我的访问IP，显示的是Apache2 Ubuntu Default Page。

运行后，报如下错误：
df: '/run/user/1000/gvfs': Permission denied

我在执行 ./create-stack-user.sh 时候遇到如下错误，请大拿帮忙看看，谢谢！
