devstack单节点安装-Rocky版本(all in one)
实验环境
- VMware Workstation 15.2
- ubuntu18.04
- 6G内存
- 40G硬盘容量
前期准备
虚拟机能访问外网，并添加一条DNS：8.8.8.8或8.8.4.4
更换源
重新编辑源
vi /etc/apt/sources.list更换内容为
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse更新源列表
sudo apt-get update更新软件（比较源，更新更高版本的软件）
sudo apt-get upgrade安装git，升级pip
sudo apt-get install git
sudo apt-get install python-pip
sudo pip install --upgrade pip
sudo pip install -U os-testr创建stack用户（此后大部分操作都在stack用户目录下执行
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更换pip源为豆瓣源（root和stack用户都需要）
sudo su
mkdir ~/.pip && vi ~/.pip/pip.conf更换为以下内容：
[global]
index-url = https://pypi.douban.com/simple
download_cache = ~/.cache/pip
[install]
use-mirrors = true
mirrors = http://pypi.douban.com/在stack用户下再次执行更换豆瓣源
- sudo su - stack 切换为stack用户
- mkdir ~/.pip && vi ~/.pip/pip.conf
此处同样更换为豆瓣源
执行下面命令更新pip软件，注意在root和stack下都要更换pip源
sudo pip install --upgrade pip下载devstack并配置local.conf
首先切换回stack用户下~目录，这里选择下载Rocky版本：
git clone https://github.com/openstack-dev/devstack -b stable/rocky切换到stack用户的devstack/files目录下，执行如下命令：
wget -c https://github.com/coreos/etcd/releases/download/v3.1.10/etcd-v3.1.10-linux-amd64.tar.gz
wget -c https://github.com/coreos/etcd/releases/download/v3.1.7/etcd-v3.1.7-linux-amd64.tar.gz这里的etcd文件会在最后执行stack.sh脚本时用到，用来安装etcd组件。不过etcd的安装包会可能由于网络问题无法成功，大家可以在网上找etcd的安装包，下载后拷贝至/files目录，同样可以成功。（本文底部提供了etcd-v3.2.17版本的资源，自取）
在stack用户的/devstack目录下配置local.conf（新建）
- vi local.conf
添加内容：
[[local|localrc]]

在/stack/devstack目录下执行./stack.sh安装脚本
./stack.sh安装成功

宿主机浏览器输入http://192.168.XX.XX/dashboard即可登陆openstack
常见问题
1.执行./stack.sh报错：stack.sh failing giving error “g-api did not start”
清理安装再重新安装：
./unstack.sh && ./clean.sh
./stack.sh2.执行./stack.sh下载cirrors镜像时连接超时
在网络上找到cirros-0.3.0-x86_64-disk.img镜像文件，下载后拷贝至/opt/stack/devstack/files/目录下（最后有资源）
3./opt/stack 目录权限问题
chmod 777 /opt/stack -R4.用户权限不足，执行./stack.sh报错：
OSError:[Errno13]Permissiondenied:’/usr/local/lib/python2.7/dist-packages/
sudo chown -R stack:stack /usr/local/lib/python2.75.执行./stack.sh报错：
WARNING: The directory ‘/opt/stack/.cache/pip/http’ or its parent directory is not owned by the curr
sudo chown -R root /opt/stack/.cache/pip/
sudo chown -R root /opt/stack/.cache/pip/http/6.执行./stack.sh报错：
env: ‘/opt/stack/requirements/.venv/bin/pip’: No such file or directory
在stack用户devstack目录下：
stack@hjc-virtual-machine:~/devstack$ virtualenv ../requirements/.venv/或stack用户~目录下执行：virtualenv …/requirements/.venv/
7.执行./stack.sh报错：Cannot uninstall ‘psutil’. It is a distutils installed project
sudo pip install qdarkstyle --ignore-installed参考博客与资源链接
