Additional information:

A new answerfile was created in: /root/packstack-answers-20210308-151632.txt
Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
Warning: NetworkManager is active on 10.130.0.148. OpenStack networking currently does not work on systems that have the Network Manager service enabled.
File /root/keystonerc_admin has been created on OpenStack client host 10.130.0.148. To use the command line tools you need to source the file.
To access the OpenStack Dashboard browse to http://10.130.0.148/dashboard .
Please, find your login credentials stored in the keystonerc_admin in your home directory.

解决方案

查看/var/tmp/packstack/20210308-151630-LdDNev/openstack-setup.log发现以下提示信息
^[[mNotice: /Stage[main]/Gnocchi::Db::Sync/Exec[gnocchi-db-sync]/returns: pkg_resources.DistributionNotFound: setuptools>=30.3^[[0m
^[[1;31mError: /Stage[main]/Gnocchi::Db::Sync/Exec[gnocchi-db-sync]: Failed to call refresh: gnocchi-upgrade --config-file /etc/gnocchi/gnocchi.conf returned 1 instead of one of [0]^[[0 m
查看实际环境中对应组件版本为python-setuptools-0.9.8
[root@controller ~]# rpm -qa | grep setuptools
python-setuptools-0.9.8-7.lns7.noarch
手动安装
[root@controller ~]# yum install -y python2-setuptools
完成后重新执行packstack --allinone

镜像->创建镜像报错

服务器报错 - OpenStack Dashboard

出错啦！

遇到异常情况，请刷新。如需帮助请联系管理员。

帮助

原因：
镜像创建过程中是将本地的iso或者其他格式的镜像上传至openstack服务器，因此过程中涉及到拷贝，所以需要对本地环境设置免密登陆
解决：
ssh-copy-id root@10.130.0.148
实例创建后启动失败，报错：

报错03

No valid host was found. There are not enough hosts available.
解决
网上查了说是可能和openstack-nova-compute有关
查看服务状态，异常，多次重启依旧异常
在这里插入图片描述
查看日志/var/log/nova/nova-compute.log提示Connection to libvirt failed: error from service: CheckAuthorization: Connection is closed: libvirtError: error from service: CheckAuthorization: Connection is closed
怀疑和libvirt有关，重启libvirtd然后重启systemctl restart openstack-nova-compute
然后openstack-nova-compute服务正常启动

报错04

Build of instance e0d58ee2-5738-4aa3-87da-f1a448650c7b aborted: Volume 3d6505f3-53c6-48ce-b54c-3b98f080e8e2 did not finish being created even after we waited 193 seconds or 61 attempts. And its status is downloading.
从错误原因上推测，OpenStack在不停尝试61次后，宣告创建实例失败。此时，卷创建依然还未完成。所以，实例创建失败的原因可能为，卷创建需要的时间比较久，在卷创建成功完成之前，Nova组件等待超时了。
解决办法
在/etc/nova/nova.conf中有一个控制卷设备重试的参数：block_device_allocate_retries，可以通过修改此参数延长等待时间。
该参数默认值为60，这个对应了之前实例创建失败消息里的61 attempts。我们可以将此参数设置的大一点，例如：300。这样Nova组件就不会等待卷创建超时，也即解决了此问题。

按照日志是执行/usr/bin/openstack flavor list --quiet --format csv --long --all时返回了1,手动执行/usr/bin/openstack flavor list --quiet --format csv --long --all并echo $?确实是1
解决方案
出现这个错误，主要是因为环境变量的问题创建admin-openrc.sh
[root@openstack zwl]# cat admin-openrc.sh
export OS_USERNAME=admin
export OS_PASSWORD=admin
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3
并执行
[root@openstack zwl]# source admin-openrc.sh

解决，因为配yum源的时候引入了红冒的源，导致puppet的版本与centos8 中默认提供的哦版本不一致
查看环境中安装的pupeet版本为puppet-6.17.0-2.el8.noarch，与centos8而centos8中提供的puppet版本为puppet-6.14.0-2.el8.noarch,修正yum源后解决此问题

解决
单独执行/usr/bin/swift-ring-builder /etc/swift/object.builder
提示six模块找不到

但是单独运行python3然后import six，没有报错，查看日志，
只是在运行/usr/bin/swift-ring-builder的时候提示找不到six模块，发现该脚本最顶部使用了#!/usr/bin/python3 -s，怀疑是-s参数导致，删除-s重新执行解决

复现方法：service glance-api restart
分析：报错中提示不能加载’glance.store.s3.Store’，初步判断是glance_store组建中模块加载失败，查看源码
_drivers/s3.py
from boto3 import session as boto_session
中引入了boto3，但是环境中只存在关于boto的包，不存在boto3,因此软件依赖存在问题，
手动安装boto3解决
apt install python3-boto3

以上两个服务对应的日志，发现二者属于同一个问题，日志信息如下：

30008 2021-06-02 15:34:01.138 16615 WARNING root [-] service_name=None

分析，
通过openstack endpoint list获取的信息来看interface=[‘internal’, ‘public’]对应的region_name为RegionOne,第一个字母大写，而代码中获取到的region_name为regionOne，第一个字母为小写，二者不一致，因此认为是配置问题导致
查看之前的所有配置，发现创建 Placement API 服务端点的时候官方指导确实是大写：https://docs.openstack.org/placement/ussuri/install/from-pypi.html
因此使用以下命令重新创建 Placement API 服务端点
openstack endpoint create --region regionOne placement public http://controller:8778

openstack endpoint create --region regionOne placement internal http://controller:8778

openstack endpoint create --region RegionOne placement admin http://controller:8778
创建完成后重新启动nova-conductor.service、nova-scheduler.service，服务正常启动

重启主机后报错
root@loongson-pc:~# openstack endpoint list
Failed to discover available identity versions when contacting http://controller:5000/v3. Attempting to parse version from URL.
Internal Server Error (HTTP 500)

配置后重启机器解决

25、nova-compute安装报错

Created symlink /etc/systemd/system/multi-user.target.wants/nova-compute.service → /lib/systemd/system/nova-compute.service.

查看日志如下
2021-06-02 16:38:07.841 25758 ERROR oslo.messaging._drivers.impl_rabbit [req-371ab1cb-0835-4696-a5be-222fbd73a851 - - - - -] Connection failed: [Errno 111] ECONNREFUSED (retrying in 10.0 seconds): ConnectionRefusedError: [Errno 111] ECONNREFUSED

查看nova相关服务发现nova-compute服务启动异常
nova-compute.service loaded activating start start OpenStack Nova Compute (nova-compute)

判断应该是链接rabbit相关组件连接失败

搜索相关nova rabbit，认为是rabbitmq服务启动问题，查看系统关于rabbit相关服务，并未启动/安装，查看系统端口确实无rabbit相关端口，也无相关服务
查看nova配置文件，确实有相关配置#transport_url = rabbit://guest:loongson@localhost:5672，因此认为是缺少rabbit相关服务导致
在x86上下载相关镜像docker pull rabbitmq:management
docker run -dit --name Myrabbitmq -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin -p 15672:15672 -p 5672:5672 rabbitmq:management

然后修改nova配置为transport_url = rabbit://admin:admin@10.2.5.156:5672，重启systemctl restart nova-compute后查看报错信息，对应问题解决

26、 nova-compute.service服务启动失败，报错日志如下

2021-06-03 08:53:54.045 26812 WARNING nova.conductor.api [req-45c09180-a3af-4366-8d81-b4fc37938aa3 - - - - -] Timed out waiting for nova-conductor. Is it running?

Reattempting establishment of nova-conductor connection…: oslo_messaging.exceptions.MessagingTimeout: Timed out waiting for a reply to message ID 306e927b3ba14fb2b3bc55675d559ad9

查看nova-conductor相关日志，提示
2021-06-03 09:08:55.677 31922 ERROR oslo_service.service pymysql.err.OperationalError: (1044, “Access denied for user ‘nova-common’@‘localhost’ to database ‘nova’”)

应该为权限问题，尝试查看nova相关配置
查看mysql中数据库，应该为novadb，因此将/etc/nova/nova.conf中nova-common的配置改为如下内容
connection = mysql+pymysql://nova-common:loongson@localhost:3306/novadb

重启nova-conductor
systemctl restart nova-conductor
查看nova-conductor日志，报错消失
查看nova-compute日志，报错消失

27、内核不支持AMD SEV

/var/log/nova/nova-compute.log中存在一下警告
2021-06-03 10:46:49.443 22894 INFO nova.virt.libvirt.host [req-60e3782b-000c-4ae7-9adb-f71357c37c42 - - - - -] kernel doesn’t support AMD SEV
分析
AMD SEV的功能为是客户机操作系统提供增强的安全性，该功能启用具有一定的先决条件，是AMD EPYC 7xx2（代码为“Rome”）或更高版本的 CPU 以及支持的 BIOS。
https://docs.vmware.com/cn/VMware-vSphere/7.0/com.vmware.vsphere.security.doc/GUID-757E2B37-C9D0-416A-AA38-088009C75C56.html

28、执行openstack compute service list报错如下

The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-24271b2b-0151-4af2-9b04-935f39f8a626)
查看compute相关日志，并未发现任何报错，查看服务状态也正常

nova list报错如下：

尝试分别重启两个服务，无任何报错，因此猜测是nova-compute服务快速启动，而libvirtd服务加载未完全导致,尝试更换两个服务启动顺序，并未出现报错

重启neutron-linuxbridge-agent服务并查看日志，ip可以正常获取，服务状态也正常
