一 摘要

本文介绍基于9台物理机部署openstack ussuri版本 以及与ceph nautils集成。

二环境信息

（一）服务器信息

（二）交换机信息

两台相同配置的交换机配置堆叠。

(三)软件信息

2.3.1 操作系统

[root@localhost ~]# cat /etc/centos-release
CentOS Linux release 8.1.1911 (Core)
[root@localhost ~]# uname -a
Linux localhost.localdomain 4.18.0-147.el8.x86_64 #1 SMP Wed Dec 4 21:51:45 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost ~]#

2.3.2 docker

2.3.3 kolla

2.3.4 kolla-ansible

三实施

（一）部署规划

3.1.1 部署网络规划

两台交互及做堆叠，服务器上有两张万兆网卡，每张网卡有两个port，交叉制作bond0,bond1;
10.3.140.0/24 bond0 用于物理机地址及api管理
10.3.141.0/24 专用于存储集群交换

10.3.142.0/24-10.3.149.0/24 用于虚拟机；

3.1.2 部署节点功能规划

（二）部署ceph 集群

ceph 集群部署请参照linux （centos 7.6）生产环境基于三台物理机 安装 ceph 集群以及集成openstack

(三) 部署openstack ussuri集群

我这里是离线部署，关于如何下载openstack ussuri包，及相关依赖
请参考openstack ussuri版本基于内网三台物理机集群kolla-ansible部署及与ceph 集群 集成

这里主要下载两类
1.是镜像
2.是部署节点安装时需要的各种依赖

3.3.1 部署前准备（控制节点和计算节点都要）

3.3.1.1 关闭防火墙以及selinux

[dev@10-3-170-32 base]$ ansible-playbook closefirewalldandselinux.yml

需要重启机器

3.3.1.2 配置dns以及修改机器名

dns 服务器上配置参考下表

修改机器名：

[root@localhost ~]# hostnamectl set-hostname procontroller01.pro.kxdigit.com
[root@localhost ~]#

以上以一台机器为例，9台机器均需设置，其中存储节点在ceph 安装时已设置，故此处只需设置6台即可。

修改服务器dns 解析地址

[dev@10-3-170-32 base]$ ansible-playbook modifydns.yml

修改ssh 配置文件 /etc/ssh/sshd_config，取消登录时调用dns,重启ssh

#UseDNS yes
UseDNS no

  systemctl restart sshd

3.3.1.3 更新yum 源

更新操作系统yum,更新docker 源

[dev@10-3-170-32 base]$ ansible-playbook updateyum.yml

[dev@10-3-170-32 base]$ ansible-playbook updateansible.yml

[root@procontroller01 ~]# ll /etc/yum.repos.d
total 12
-rw-r--r-- 1 root root 501 Apr 29 14:55 CentOS-81.repo
-rw-r--r-- 1 root root  91 Apr 29 15:26 ansible2910forcentos8.repo
-rw-r--r-- 1 root root 104 Apr 29 14:55 docker1803forcentos8.repo
[root@procontroller01 ~]#

3.3.1.4 同步时间服务器

[dev@10-3-170-32 base]$ ansible-playbook modifychronyclient.yml

3.3.1.5 安装docker

控制节点 计算节点 逐台安装,以下一控制节点一为例只需
安装、修改配置文件、设置开机启动

我这里目前安装的是docker 18.03,三台节点都需要安装
我这里已经配置了docker yum 源，直接yum install docker-ce 即可安装，安装时可能会报错，主要是依赖包兼容问题。
安装docker 异常处理参考openstack ussuri 版本 all-in-one 离线部署

[root@procontroller01 ~]#  yum install docker-ce
Failed to set locale, defaulting to C.UTF-8
Last metadata expiration check: 0:01:16 ago on Thu Apr 29 14:56:36 2021.
Modular dependency problems:

若有该包兼容性错误，可以删除

 yum remove podman

docker 配置文件修改

新增 /etc/systemd/system/docker.service.d/kolla.conf

[root@procontroller01 ~]# cd /etc/systemd/system/

[root@procontroller01 system]# mkdir docker.service.d
[root@procontroller01 system]# cd docker.service.d/
[root@procontroller01 docker.service.d]# vi kolla.conf
[root@procontroller01 docker.service.d]#

文件内容如下

[Service]
MountFlags=shared

设置开机启动

[root@procontroller01 docker.service.d]# systemctl daemon-reload
[root@procontroller01 docker.service.d]# systemctl restart docker && systemctl enable docker && systemctl status docker

3.3.1.6 安装dpip

centos8.1 自带python3，默然安装了pip3.6 ，我们只需要做下链接即可。

3.3.2.2.1 制作pip链接

3.3.2 安装部署服务(部署服务器)

3.3.2.1 安装ansible

3.3.2.1.1 安装ansible

[root@procontroller01 ~]# yum install ansible
Failed to set locale, defaulting to C.UTF-8
ansible

[root@procontroller01 ~]#

3.3.2.1.2 修改ansible 配置文件

对ansible /etc/ansible/ansible.cfg 配置文件做了优化
先备份原文件：cp /etc/ansible/ansible.cfg /etc/ansible/ansible.cfg.bak.orig

新增如下内容：

[defaults]
inventory  = $HOME/ansible/hosts
host_key_checking=False
pipelining=True
forks=10

3.3.2.2 安装基础依赖

centos8 使用dnf 安装rpm 包，安装python3-devel libffi-devel gcc openssl-devel python3-libselinux git vim bash-completion net-tools 基础依赖包

3.3.3 kolla ansible 部署openstack准备工作

下面上传的是train 版本镜像，ussuri 版本上传方法类似，只是上传的内容以及镜像tag 不同。

这里主要是配置文件的初步修改，镜像上传到内网镜像中心,
我这里内网有个docker 仓库，而且是https方式
https://registry.kxdigit.com

非https 方式，docker 需要配置。

3.3.3.1 镜像上传到内网镜像中心

3.3.3.1.1 上传到内网

部署节点新增目录

[root@procontroller01 software]# mkdir -p ./openstack/train/images/kolla
[root@procontroller01 software]# cd openstack/train/images/kolla/
[root@procontroller01 kolla]# pwd
/root/software/openstack/train/images/kolla
[root@procontroller01 kolla]#

openstak 镜像导入内网

此步骤略
我这边镜像到上传到部署节点,总共134个镜像

3.3.3.1.2 解压镜像压缩包

解压脚本

#! /bin/sh

for i in ` ls -al /root/software/openstack/train/images/kolla/  | grep gz | awk ‘{print $9}‘ `;do gzip -d /root/software/openstack/train/images/kolla/$i; done

3.3.3.1.3 批量加载镜像

脚本

[root@procontroller01 scripts]# cat dockerload.sh
#!/bin/bash

  path=$1
  cd $path

  for filename in `ls`
  do
    echo $filename
    docker load < $filename
  done

[root@procontroller01 scripts]#

执行命令：

[root@procontroller01 scripts]# ./dockerload.sh /root/software/openstack/train/images/kolla/

3.3.3.2 生成密码文件并修改登录密码（部署节点）

先使用kolla-genpwd 生成全套密码，然后为了前台便于登录，修改keystone_admin_password 密码 为Admin_PASS2021

3.3.3.3 修改multinode（部署节点）

主要修改点有：
[control]
[network]
[compute]
[monitoring]
[storage]
这条我这里暂时没改，先试试能不能用
[nova-compute-ironic:children] 配置改为compute

仅放了修改的地方

[root@procontroller01 ansible]# cat multinode
# These initial groups are the only groups required to be modified. The
# additional groups are for more control of the environment.
[control]
# These hostname must be resolvable from your deployment host
procontroller01.pro.kxdigit.com
procontroller02.pro.kxdigit.com
procontroller03.pro.kxdigit.com

# The above can also be specified as follows:
#control[01:03]     ansible_user=kolla

# The network nodes are where your l3-agent and loadbalancers will run
# This can be the same as a host in the control group
[network]
procontroller01.pro.kxdigit.com
procontroller02.pro.kxdigit.com
procontroller03.pro.kxdigit.com

[compute]
procompute01.pro.kxdigit.com
procompute02.pro.kxdigit.com
procompute03.pro.kxdigit.com

[monitoring]
procontroller02.pro.kxdigit.com

# When compute nodes and control nodes use different interfaces,
# you need to comment out "api_interface" and other interfaces from the globals.yml
# and specify like below:
#compute01 neutron_external_interface=eth0 api_interface=em1 storage_interface=em1 tunnel_interface=em1

[storage]

[deployment]
localhost       ansible_connection=local


[nova-compute-ironic:children]
#nova
compute

3.3.3.4 修改global.yml（部署节点）

此步暂略，后面与ceph 集成时也要修改该文件，整合到一起。

3.3.4 openstack与 ceph 集成

3.3.4.1 修改global.yml
