在献祭了四个晚上之后, 终于在 ubuntu 上用 devstack 成功安装 openstack, 那么请问成功的秘诀是什么, 成功的秘诀就是, 别看 CSXN 上的那些教程, 一顿操作猛如虎, 最后完全安装不上. 一个 local.conf 文件几百行, 结果最后 几行的 local.conf 更加顶用, 另外千万别设置国内的 git 镜像, 虽然拉的慢, 但是能跑! 也不要拉那些很老的稳定分支, 直接拉 master 即可.
下面将介绍如何在 Ubuntu 上安装 devstack, 绝对没有猛如虎的操作, 简单佛系低门槛安装.
- 准备
打开你的 PS4 或者 准备一部电影 或者 打开你还没写完的代码 / 文章
- 更新你的系统并且重启
$ sudo apt update
$ sudo apt -y upgrade
$ sudo apt -y dist-upgrade
$ sudo apt install git -y
$ sudo reboot
- 创建并切换到 stack 用户
$ sudo useradd -s /bin/bash -d /opt/stack -m stack
# sudo 不需要密码
$ echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
$ sudo su - stack
- 下载和配置 devstack
$ cd /opt/stack/
$ git clone https://git.openstack.org/openstack-dev/devstack
$ cd devstack
$ cat > local.conf <<EOF
[[local|localrc]]
# Password for KeyStone, Database, RabbitMQ and Service
ADMIN_PASSWORD=YOUPASSWORD
DATABASE_PASSWORD=YOUPASSWORD
RABBIT_PASSWORD=YOUPASSWORD
SERVICE_PASSWORD=YOUPASSWORD
# Host IP - get your Server/VM IP address from ip addr command
# 修改成你的机器的 IP
HOST_IP=192.168.10.100
EOF
如果你的系统是 19.04 之类的比较新的系统, 由于 openstack 未在该系统上测试过, 所以你需要在 local.conf 中加上
$ cat >> local.conf <<EOF
FORCE=yes
EOF
然后你可以设置下 APT 的镜像源, 以及 pip 的镜像源
设置 ustc 的 apt 镜像 (此处示例为 19.04, 如为其他版本则需要自行修改)
$ cat > /etc/apt/sources.list <<EOF

设置 pip 镜像
$ mkdir ~/.pip
$ echo > ~/.pip/pip.conf <<EOF
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
EOF
强烈建议不要设置 git 镜像为国内, 血泪教训, (不清楚是同步问题还是怎样, 各种异常)
- 运行 devstack 安装 openstack
$ ./stack.sh
然后你就可以继续做你的事情了, 等到安装完之后会显示安装所花的时间以及 账号密码, 以及 dashboard 的地址
ps:
中间可能会碰到获取 Etcd 失败的问题, 可以手动下载,然后移动到
/opt/stack/devstack/files下
- 访问 openstack 开始享用把
如果安装中碰到问题可以到 kblog 发 issue 讨论
