前言：建议参考官方文档https://docs.openstack.org/pike/install/

参看文章：https://www.cnblogs.com/blacklonging/p/7881048.html

本文架构设置参考上文，基本可以完整设置。有部分问题，参考官方文档可解决。

环境准备：VMware® Workstation 14

1、虚拟机配置

内存，cpu 略有不同，自己配置即可

Controller节点：
系统：CentOS7.6 64位（最小化安装）
处理器：4核
内存：4G
硬盘：100G
网卡：3块

Compute节点：
系统：CentOS7.6 64位（最小化安装）
处理器：4核
内存：4G
硬盘：100G
网卡：3块

Cinder节点：
系统：CentOS7.6 64位（最小化安装）
处理器：4核
内存：1G
硬盘：100G+50G
网卡：3块

前期准备：安装源，修改网络地址，安装必备环境包（在修改任何系统环境配置文件前，请备份）

修改源请自己百度，参看其他文章

1. 备份本地yum源
cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bak
2.获取阿里yum源配置文件
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
3.更新cache
yum makecache
4.查看
yum -y update

yum -u upgrade

 

 1、关闭防火墙

2、

最后环境中文件如下：

CentOS-Base.repo
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.

四、清除当前yum缓存并重新建立新的缓存

yum clean all
yum makecache

 

如果以上步骤不报错，则说明源配置的没问题。

五、安装必须的工具

yum install net-tools wget vim ntpdate ntp bash-completion -y

六、更改主机名

编辑/etc/hostname，将默认主机名改为你想要的主机名，本次实验的主机名如下：
Controller节点：controller
Compute节点：compute
Cinder节点：cinder

七、添加各节点的hosts信息

编译/etc/hosts，增加各节点IP及主机名的对应关系，这里IP地址使用VMnet1网段的IP，以下是Controller节点的hosts文件，其余节点同样添加：

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.1.1.10 controller
10.1.1.101 compute
10.1.1.102 cinder

/etc/hosts

建议现修改网卡信息，是网络能用。

 

 

主要问题；记录：

　　问题:The request you have made requires authentication. (HTTP 401) (Request-ID: rxxxxx

　　　　身份认证问题

　　　　

vi /etc/keystone/keystone.conf

找到这一行：

#admin_token = <None>

将注释取消 

root用户下不需要加su

刷库
# /bin/sh -c "keystone-manage db_sync"

问题：

ERROR oslo_service.service AccessRefused: (0, 0): (403) ACCESS_REFUSED - Login was refused using authentication mechanism AMQPLAIN. For details see the broker logfile.

创建过程中出现一次 Rabbitmq未创建成功openstack用户问题。openstack丢了，DHCP起不来。重建用户即可

 

问题：

http://192.168.17.140/dashboard/    500  

http://contrller/dashboard/    500 错误

 解决办法：　　

在/etc/httpd/conf.d/openstack-dashboard.conf 加入 WSGIApplicationGroup %{GLOBAL}

问题已解决，

或者  原因是/etc/openstack-dashboard/local.settings 权限是root权限，执行chown root:apache /etc/openstack-dashboard/完美解决问题（ 亲测是要给local.setting文件权限才行）

 chown root:apache /etc/openstack-dashboard/local_settings

 

 

问题（安装compute出现）：

　　需要:qemu-kvm-rhev >= 2.9.0

解决：先参考其他文档解决，如不行，执行安装

　　yum install centos-release-openstack-pike
