## 版本支持概述 ##

### Centos7 ###

源中包含以下版本的openstack，不排除之后会支持，新版本的OpenStack  
openstack-queens  
openstack-rocky  
openstack-stein  
openstack-train

### centos 8 ###

openstack-train  
openstack-ussuri  
openstack-victoria  
如果安装OpenStack Victoria，需要在CentOS 8上

CentOS-7-x86\_64-GenericCloud.qcow2镜像配置实例密码  
官方镜像http://cloud.centos.org/centos/

openstack环境中，使用官方镜像CentOS-7-x86\_64-GenericCloud.qcow2，不知道默认密码，可以在创建实例时候配置脚本写入root密码

#!/bin/bash
    passwd root<<EOF
    root
    root
    EOF

## CentOS8配置的基础配置 ##

[基本安装与配置ssh登录][ssh]

1  dnf install openssh openssh-server -y
     2  dnf install openssh openssh-server vim git wget net-tools bash-completion -y
     3  ifconfig
     4  vim /etc/ssh/sshd_config
     5  systemctl enable sshd
     6  systemctl restart sshd
     7  systemctl status sshd
     10  #q退出
     11  exit
     12  history

原生镜像安装ssh ，允许root的ssh登录

### 配置国内源 ###

[国内源配置][Link 1]

# 移除原系统自带的repo文件，避免和新建的配置文件内容冲突
    mkdir ori_repo-config
    mv /etc/yum.repos.d/* ./ori_repo-config/
    touch /etc/yum.repos.d/CentOS-PrivateLocal.repo
    vim /etc/yum.repos.d/CentOS-PrivateLocal.repo

#下载阿里云源文件
    wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo
    
    #替换 阿里云镜像地址
    sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
    
    #建立缓存
    yum makecache

## yum源制作 ##

yum clean all
    yum makecache
    yum -y install vim createrepo yum-utils httpd net-tools 
    # yum -y install reposync
    yum install -y centos-release-openstack-victoria
    ls -1 /etc/yum.repos.d/
    yum repolist

## 同步至本地 ##

mkdir -p /var/www/html/yumrepository
    systemctl restart httpd.service
    netstat -lntp
    reposync -p /var/www/html/yumrepository/

1  dnf install openssh openssh-server wget git vim net-tools bash-completion -y
        2  ifconfig
        3  systemctl enable sshd
        4  systemctl restart sshd
        5  vim /etc/ssh/sshd_config
        6  systemctl restart sshd
        7  systemctl status sshd
        8  ifconfig
        9  exit
       10  ls
       11  mkdir ori_repo-config
       12  mv /etc/yum.repos.d/* ./ori_repo-config/
       13  wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo
       14  sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
       15  yum makecache
       16  yum -y install vim createrepo yum-utils httpd net-tools
       17  yum install -y centos-release-openstack-victoria
       18  ls -1 /etc/yum.repos.d/
       19  yum repolist
       20  mkdir -p /var/www/html/yumrepository
       21  systemctl restart httpd.service
       22  reposync -p /var/www/html/yumrepository/
       23  exit
       24  reposync -p /var/www/html/yumrepository/
       25  reposync -p /var/www/html/yumrepository/
       26  exit
       27  history

## 本地制作 ##

创建yum仓库

# 利用createrepo工具制作yum源，如果没有createrepo工具则利用yum安装
    yum install createrepo -y
    #进入每一个文件夹
    cd /var/www/html/yumrepository
    cd ./base
    ls
    createrepo .
    ls

注意，在同步下来的每一个yum仓库目录都需要执行，上述操作

## 配置服务httpd ##

#启动服务
    systemctl restart httpd
    # 设置开机自动启动
    systemctl enable httpd
    systemctl status httpd
    q

修改配置文件 /etc/selinux/config

# vim /etc/selinux/config
    SELINUX=disabled

yum install firewalld systemd -y
    systemctl start firewalld.service
    systemctl stop firewalld.service
    systemctl enable firewalld.service
    systemctl disable firewalld.service
    netstat -anp

[https://blog.csdn.net/bo123\_/article/details/101484987][https_blog.csdn.net_bo123_article_details_101484987]

55  systemctl stop firewalld NetworkManager.service
       56  systemctl stop NetworkManager.service
       57  yum install iptables-services
       58  systemctl stop firewalld NetworkManager.service
       59  systemctl stop firewalld
       60  systemctl status firewalld
       61  systemctl start firewalld
       62  yum install firewalld systemd -y
       63  systemctl start firewalld.service
       64  systemctl stop firewalld.service
       65  systemctl status firewalld
       66  netstat -anp
       67  systemctl disable firewalld NetworkManager.service
       68  systemctl status firewalld NetworkManager.service
       69  setenforce 0
       70  ifconfig
       71  yum repolist
       72  ls ../

关闭防火墙，selinux，NetworkManager

systemctl stop firewalld NetworkManager.service
    systemctl disable firewalld NetworkManager.service
    systemctl status firewalld NetworkManager.service
    setenforce 0

## 验证 ##

在另一台机器，新建一个repo文件

注意：  
①IP地址更换为yumrepository所在主机的地址。  
②为避免安装冲突，\[centos-openstack-stein\]和\[centos-openstack-train\]只保留一个。

[AppStream]
    name=CentOS-$releasever - AppStream - mirrors.aliyun.com

    [centos-rabbitmq-38]
    name=CentOS-$releasever - RabbitMQ 38
    baseurl=http://192.168.2.104/yumrepository/centos-rabbitmq-38/
    gpgcheck=0

配置完成后，通常需要清除yum中原有的cache，并重新生成cache。清除yum陈旧cache的命令如下：

yum clean all
    yum makecache
