+-------------+--------------+---------+-----------+------------------------------+------------------+------------------+

1、网络环境

主机 IP
controller 10.0.0.51
compute1 10.0.0.61

修改hosts文件
cat /etc/hosts
10.0.0.51 controller
10.0.0.61 compute1

关闭selinux、firewalld

cat env_set.sh 
#!/bin/bash

systemctl  stop firewalld
systemctl  disable firewalld

setenforce 0
sed  -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
yum install -y wget

配置阿里yum源

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

手动配置阿里源

[centotack-rocky]
name=openstack-rocky
baseurl=https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-rocky/
enabled=1
gpgcheck=0

[qume-kvm]
name=qemu-kvm
baseurl= https://mirrors.aliyun.com/centos/7/virt/x86_64/kvm-common/
enabled=1
gpgcheck=0

安装openstack客户端和openstack-selinux
yum install python-openstackclient openstack-selinux -y

2、同步时间

安装相关软件
yum install chrony vim net-tools lsof -y

#controller节点
allow 10.0.0.0/24

#其他节点
server 10.0.0.51 iburst
重启服务

systemctl enable chronyd.service
systemctl start chronyd.service

3、部署mariadb数据库

数据库节点

yum install mariadb mariadb-server python2-PyMySQL -y

修改数据库配置文件 /etc/my.cnf

bind-address = 10.0.0.51
default-storage-engine = innodb
innodb_file_per_table		#innodb使用独立的表结构
max_connections = 4096		#最大的连接数
collation-server = utf8_general_ci	#使用utf-8字符集
character-set-server = utf8

启动数据库

systemctl enable mariadb
systemctl start mariadb

数据库安全初始化

mysql_secure_installation
	#回车 n y y y y

4、消息队列RabbitMQ

安装rabbit

yum install rabbitmq-server
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service

#添加openstack用户，设置密码
rabbitmqctl add_user openstack RABBIT_PASS
	Creating user "openstack" ...
#给openstack用户配置写和读权限
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
		Setting permissions for user "openstack" in vhost "/" ...

Rabbitmq默认会开启25672和5672端口
验证：

# netstat -antplu|grep 5672
tcp        0      0 0.0.0.0:25672           0.0.0.0:*               LISTEN      11226/beam.smp      
tcp6       0      0 :::5672                 :::*                    LISTEN      11226/beam.smp

开启插件，监控. 端口：15672

rabbitmq-plugins enable rabbitmq_management

# netstat -antplu|grep 5672
tcp        0      0 0.0.0.0:25672           0.0.0.0:*               LISTEN      11226/beam.smp      
tcp        0      0 0.0.0.0:15672           0.0.0.0:*               LISTEN      11226/beam.smp
tcp6       0      0 :::5672                 :::*                    LISTEN      11226/beam.smp

5、配置memcached

	yum install -y memcached python-memcached 
	#默认监听需要修改
	sed -i 's/127.0.0.1/10.0.0.51/g' /etc/sysconfig/memcached
	systemctl  restart memcached.service

验证：

# netstat -anpl|grep 11211
tcp        0      0 10.0.0.51:11211         0.0.0.0:*               LISTEN      12152/memcached

6、openstack服务安装的通用步骤：

1.创库授权
2.在keystone创建用户，关联角色
3.在keystone上注册服务，注册api
4.安装服务相关的软件包
5.修改配置文件 		数据库的连接信息 		rabbitmq的连接信息 		keystone认证授权信息
6.同步数据库，创建表
7.启动服务

二、keystone服务的安装

1、创库授权

create DATABASE keystone;
GRANT ALL PRIVILEGES on keystone.* to 'keystone'@'localhost'  identified by 'KEYSTONE_DBPASS';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'KEYSTONE_DBPASS';

2、安装keystone相关软件包

yum install -y openstack-keystone httpd mod_wsgi

修改配置文件

cp /etc/keystone/keystone.conf{ 
   ,.back}
grep -Ev '^$|^#' /etc/keystone/keystone.conf.back > /etc/keystone/keystone.conf
cat /etc/keystone/keystone.conf
[DEFAULT]
admin_token = ADMIN_TOKEN

connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone

[token]
provider = fernet


#同步数据库
su -s /bin/sh -c "keystone-manage db_sync" keystone

#初始化fernet
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
#验证
ll /etc/keystone

3、配置httpd

echo "ServerName controller" >>/etc/httpd/conf/httpd.conf
cat /etc/httpd/conf.d/wsgi-keystone.conf
Listen 5000
Listen 35357

<VirtualHost *:5000>
    WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{ 
   GROUP}

#配置认证令牌：
export OS_TOKEN=ADMIN_TOKEN
#配置端点URL：
export OS_URL=http://controller:35357/v3
#配置认证 API 版本：
export OS_IDENTITY_API_VERSION=3

openstack service create \
  --name keystone --description "OpenStack Identity" identity

openstack endpoint create --region RegionOne \
  identity public http://controller:5000/v3

openstack endpoint create --region RegionOne \
  identity internal http://controller:5000/v3

openstack endpoint create --region RegionOne \
  identity admin http://controller:35357/v3

创建域、项目、用户、角色

openstack domain create --description "Default Domain" default

openstack project create --domain default \
  --description "Admin Project" admin

openstack user create --domain default \
  --password ADMIN_PASS admin

openstack role create admin

openstack role add --project admin --user admin admin

openstack project create --domain default \
  --description "Service Project" service

退出bash
给定初始变量

# cat admin-openrc 
export OS_AUTH_URL=http://controller:35357/v3 
export OS_PROJECT_DOMAIN_NAME=default 
export OS_USER_DOMAIN_NAME=default 
export OS_PROJECT_NAME=admin 
export OS_USERNAME=admin 
export OS_IMAGE_API_VERSION=2
export OS_IDENTITY_API_VERSION=3
export OS_PASSWORD=ADMIN_PASS

6.同步数据库，创建表

#网络服务初始化脚本
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
 su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \ --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron

7.启动服务

systemctl restart openstack-nova-api.service

systemctl enable neutron-server.service \
  neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
  neutron-metadata-agent.service
systemctl start neutron-server.service \
  neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
  neutron-metadata-agent.service

# ll /etc/openstack-dashboard/local_settings 
-rw-r-----. 1 root apache 26505 Apr 28 21:56 /etc/openstack-dashboard/local_settings

对域的修改

vim /etc/httpd/conf.d/openstack-dashboard.conf
   WSGIApplicationGroup %{ 
   GLOBAL}
   systemctl  restart httpd

七、创建一个实例

1、创建网路

neutron net-create --shared --provider:physical_network provider \
  --provider:network_type flat ouzhenet
  
 neutron subnet-create --name ouzhe1 \
  --allocation-pool start=10.0.0.101,end=10.0.0.200 \
  --dns-nameserver 114.114.114.114 --gateway 10.0.0.2 \
  ouzhenet 10.0.0.0/24

2、创建m1.nano规格的主机

openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano

3、生成和添加秘钥对

ssh-keygen -q -N "" -f ~/.ssh/id_rsa
openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey

4、增加安全组规则

openstack security group rule create --proto icmp default
openstack security group rule create --proto tcp --dst-port 22 default

5、创建主机

neutron net-list
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
+--------------------------------------+----------+----------------------------------+--------------------------------------------------+
| id                                   | name     | tenant_id                        | subnets                                          |
+--------------------------------------+----------+----------------------------------+--------------------------------------------------+
| cae26611-d5d1-4465-a352-c35a014e6f08 | ouzhenet | fd444319c4874e908d66d1c91e07c42d | 29281230-6848-4397-bfec-241c5e8c9e65 10.0.0.0/24 |
+--------------------------------------+----------+----------------------------------+--------------------------------------------------+

openstack server create --flavor m1.nano --image cirros \
  --nic net-id=cae26611-d5d1-4465-a352-c35a014e6f08 --security-group default \
  --key-name mykey ouzhe001

验证创建的虚拟机
