如何在 Hetzner 中安装 RDO（OpenStack）？

我曾尝试在 Hetzner（专用服务器）上安装 OpenStack，但无法正确完成安装。

我遵循了以下官方指南：

RDO 安装

我在家里的电脑上进行了同样的安装，没有遇到任何问题。

$ sudo yum install -y centos-release-openstack-pike
$ sudo yum update -y
$ sudo yum install -y openstack-packstack
$ sudo packstack --allinone

$ sudo systemctl disable firewalld
$ sudo systemctl stop firewalld
$ sudo systemctl disable NetworkManager
$ sudo systemctl stop NetworkManager
$ sudo systemctl enable network
$ sudo systemctl start network

$ sudo yum install -y centos-release-openstack-pike
yum-config-manager --enable openstack-pike
$ sudo yum update -y

$ sudo yum install -y openstack-packstack
$ sudo packstack --allinone

问题肯定是 Hetzner 提供直接路由到您的机器的单个浮动 IP 或 RIPE 块。

有人遇到过这个问题，可以提供一点帮助。

我在这里添加错误信息：

遇到了同样的问题，通过改变 puppet 的超时值解决了该问题。

/usr/share/openstack-puppet/modules/nova/manifests/db/sync.pp

class nova::db::sync(
  $extra_params    = undef,
  $db_sync_timeout = 300,
)

将 $db_sync_timeout 从 300 更改为 3600

我必须对中子做出同样的改变 /usr/share/openstack-puppet/modules/neutron/manifests/db/sync.pp

在 Centos7、Packstack Train 上遇到了同样的问题。硬件 HP DL580，40CPU，80Threaads，8 x SSD，RAID0。如果有人使用 ansible 部署 Packstack，我会做一个小的 ansible 任务

确保你已经安装了 NTP 服务并且它正常工作。正如你在 packstack 结果中看到的那样：

* Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
