# 基本规划 #

# 环境准备 #

## 1.主机基础网络配置 ##

网卡配置,配置静态IP地址

配置文件内容如下

cat /etc/sysconfig/network-scripts/ifcfg-ens33

[root@compute1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens33
    TYPE=Ethernet
    PROXY_METHOD=none
    BROWSER_ONLY=no
    #BOOTPROTO=dhcp
    DEFROUTE=yes
    IPV4_FAILURE_FATAL=no
    IPV6INIT=yes
    IPV6_AUTOCONF=yes
    IPV6_DEFROUTE=yes
    IPV6_FAILURE_FATAL=no
    #IPV6_ADDR_GEN_MODE=stable-privacy
    NAME=ens33
    UUID=66e5a322-41bd-462d-bb10-b080ab3b3d44
    DEVICE=ens33
    ONBOOT=yes
    
    # add follow
    BOOTPROTO="static"
    IPADDR="192.168.139.111"
    NETMASK="255.255.255.0"
    GATEWAY="192.168.139.2"
    DNS1="1.1.1.1"
    [root@compute1 ~]#

cat /etc/sysconfig/network-scripts/ifcfg-ens34

[root@compute1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens34
    TYPE=Ethernet
    PROXY_METHOD=none
    BROWSER_ONLY=no
    BOOTPROTO=dhcp
    DEFROUTE=yes
    IPV4_FAILURE_FATAL=no
    IPV6INIT=yes
    IPV6_AUTOCONF=yes
    IPV6_DEFROUTE=yes
    IPV6_FAILURE_FATAL=no
    IPV6_ADDR_GEN_MODE=stable-privacy
    NAME=ens34
    UUID=f9f07eb6-dbf0-4e8d-aee0-d3e94bfae78a
    DEVICE=ens34
    ONBOOT=yes
    [root@compute1 ~]#

网关配置

cat /etc/networks

[root@compute1 ~]# cat /etc/networks
    default 0.0.0.0
    loopback 127.0.0.0
    link-local 169.254.0.0
    
    #add follow
    NETWORKING=yes
    GATEWAY=192.168.139.2
    [root@compute1 ~]#

systemctl restart NetworkManager

## 2.hostname主机名配置 ##

控制节点

hostnamectl set-hostname compute1
    echo 192.168.139.101 controller >> /etc/hosts
    echo 192.168.139.111 compute1 >> /etc/hosts
    echo 192.168.139.112 compute2 >> /etc/hosts

计算节点1

hostnamectl set-hostname compute1
    echo 192.168.139.101 controller >> /etc/hosts
    echo 192.168.139.111 compute1 >> /etc/hosts
    echo 192.168.139.112 compute2 >> /etc/hosts

计算节点2

hostnamectl set-hostname compute2
    echo 192.168.139.101 controller >> /etc/hosts
    echo 192.168.139.111 compute1 >> /etc/hosts
    echo 192.168.139.112 compute2 >> /etc/hosts

验证联通性

ping -c 4 controller
    ping -c 4 compute1
    ping -c 4 compute2
    ping -c 4 qq.com

## 3.免密登录（可选） ##

## 4.禁用防火墙 ##

（1）关闭iptables

systemctl stop firewalld.service
    systemctl disable firewalld.service
    systemctl status firewalld.service

（2）关闭 selinux

setenforce 0
    getenforce
    sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/sysconfig/selinux
    grep SELINUX=disabled /etc/sysconfig/selinux

## 5.yum源配置 ##

（1）新建repo文件

cd
    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

文件内容：/etc/yum.repos.d/CentOS-PrivateLocal.repo

[AppStream]
    name=CentOS-$releasever - AppStream - mirrors.aliyun.com
    baseurl=http://192.168.2.104/yumrepository/AppStream/
    gpgcheck=0
    enabled=1
    
    [base]
    name=CentOS-$releasever - Base - mirrors.aliyun.com
    baseurl=http://192.168.2.104/yumrepository/base/
    gpgcheck=0
    enabled=1
    
    [centos-advanced-virtualization]
    name=CentOS-$releasever - Advanced Virtualization
    baseurl=http://192.168.2.104/yumrepository/centos-advanced-virtualization/
    gpgcheck=0
    enabled=1
    
    [centos-ceph-nautilus]
    name=CentOS-$releasever - Ceph Nautilus
    baseurl=http://192.168.2.104/yumrepository/centos-ceph-nautilus/
    gpgcheck=0
    enabled=1
    
    [centos-nfv-openvswitch]
    name=CentOS-$releasever - NFV OpenvSwitch
    baseurl=http://192.168.2.104/yumrepository/centos-nfv-openvswitch/
    gpgcheck=0
    enabled=1
    
    [centos-openstack-ussuri]
    name=CentOS-$releasever - OpenStack victoria
    baseurl=http://192.168.2.104/yumrepository/centos-openstack-ussuri/
    gpgcheck=0
    enabled=1
    
    [centos-rabbitmq-38]
    name=CentOS-$releasever - RabbitMQ 38
    baseurl=http://192.168.2.104/yumrepository/centos-rabbitmq-38/
    gpgcheck=0
    enabled=1
    
    [extras]
    name=CentOS-$releasever - Extras - mirrors.aliyun.com
    baseurl=http://192.168.2.104/yumrepository/extras/
    gpgcheck=0
    enabled=1

注意：在配置完成私有的yum源之后，网络允许的情况下，建议增加阿里云的源，以便安装部分系统依赖软件。  
（因下面的安装遇到没有Python3环境）

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
    wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo
    sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo

(2)更新软件源

yum clean all
    yum makecache
    yum repolist

# 系统基础软件工具安装与配置 #

## 1.基础 ##

yum install -y lsof vim net-tools wget git

yum install net-tools wget vim bash-completion lrzsz unzip zip -y

dnf install openssh openssh-server vim git wget net-tools bash-completion -y

## 2.NTP时间同步 ##

yum  -y install chrony

vim /etc/chrony.conf

# add follow
    server controller iburst

systemctl restart chronyd.service
    systemctl enable chronyd.service
    systemctl list-unit-files |grep chronyd.service
    systemctl status chronyd.service

timedatectl set-timezone Asia/Shanghai
    chronyc sources
    timedatectl status

# OpenStack基础软件安装 #

## 1.本步骤可**省略** ##

\*\*!!!\*\*省略

yum clean all
    yum makecache
    yum repolist
    yum install centos-release-openstack-ussuri -y
    yum clean all
    yum makecache

## 2.OpenStack客户端相关软件 ##

参考：

[OpenStack packages for RHEL and CentOS][]

[1 Openstack-Ussuri集群部署-环境准备-centos8][1 Openstack-Ussuri_-_-centos8]

mv CentOS-PrivateLocal.repo /root/
    ls
    wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo
    sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
    yum clean all
    yum makecache
    cp /root/CentOS-PrivateLocal.repo ./root/
    dnf  install wntp -y
    ntpdate ntp3.aliyun.com
    yum install -y python3-openstackclient.noarch
    yum config-manager --set-enabled PowerTools
    history

When installing the Ussuri release, run:

[For CentOS8, you will also need to enable the PowerTools repository.][OpenStack packages for RHEL and CentOS]

# yum install centos-release-openstack-ussuri
    # yum config-manager --set-enabled PowerTools
    yum install -y python3-openstackclient.noarch
    yum config-manager --set-enabled PowerTools
    history

安装Ussuri版yum源 - 每台部署

yum install python3-openstackclient -y
    yum config-manager --set-enabled PowerTools
    yum install openstack-selinux -y
