openstack入门及应用
一、OpenStack云计算的介绍
（一）云计算的服务类型
IAAS：基础设施即服务，如：云主机
PAAS:平台即服务，如：docker
SAAS:软件即服务，如：购买企业邮箱，CDN
| 传统IT | IAAS | PAAS | SAAS |
|---|---|---|---|
| 1应用 | 你管理 | 你管理 | 服务上管理 |
| 2数据 | 你管理 | 你管理 | 服务上管理 |
| 3运行时 | 你管理 | 服务上管理 | 服务上管理 |
| 4中间件 | 你管理 | 服务上管理 | 服务上管理 |
| 5操作系统 | 服务上管理 | 服务上管理 | 服务上管理 |
| 6虚拟化 | 服务上管理 | 服务上管理 | 服务上管理 |
| 7服务器 | 服务上管理 | 服务上管理 | 服务上管理 |
| 8存储 | 服务上管理 | 服务上管理 | 服务上管理 |
| 9网络 | 服务上管理 | 服务上管理 | 服务上管理 |
（二）openstack定义：
是开源的云计算管理平台项目，通过各种互补的服务提供了基础设施即服务（IAAS）的解决方案，每个服务提供API以进行集成。
版本：A~Z命名，docs.openstack.org
openstack架构模块：
horizon：UI界面。
Neutron：网络
clinder：硬盘
nova：计算
Glance：镜像
VM:虚拟机
keystone：授权
cellometer：监控
swift：校验
heat：编排
openst核心组件：
计算：Nova。一套控制器，用于为单个用户或使用群组管理虚拟机实例的整个生命周期，负责虚拟机创建、开机、关机、挂起、暂停、调整、迁移、重启、销毁等操作。
镜像服务：Glance。一套虚拟机镜像查找及检索，支持多种虚拟机镜像格式（AKI,AMI,ARI,ISO,QCOW2,RAW,VMDK）,有创建上传镜像、删除镜像、编辑镜像基本信息的功能。
身份服务：keystone。为openstack其他服务提供身份验证、服务规则和服务令牌功能，管理Domains,Projects,Users,Groups,Roles.
网络&地址管理：Neutron。
块存储：Cinder。
UI界面：Horizon。
soa架构介绍：
soa（拆业务）千万用户同时访问。每个网页都是一个集群。
（三）OpenStack基础服务的安装
（1）配置控制节点和计算节点：
[root@computer1 /]# cat /etc/hosts
10.0.0.11 controller
10.0.0.31 computer1
10.0.0.32 computer2
[root@computer1 /]#
（2）配置控制节点和计算节点的yum源：
[root@computer1 etc]# mount /dev/cdrom /mnt/
[root@computer1 etc]# cat /etc/rc.local
mount /dev/cdrom /mnt/
[root@computer1 etc]# chomd +x /etc/rc.local
将资料包里的openstack的rpm上传至/opt,并解压
[root@computer1 opt]# cat /etc/yum.repos.d/local.repo
[local]
name=local
baseurl=file:///mnt
gpgcheck=0
[openstack]
name=openstack
baseurl=file:///opt/repo
gpgcheck=0
[root@controller /]# yum makecache
（3）安装时间同步chrony，并配置：
控制节点：
[root@controller /]# yum install chrony -y
[root@controller /]# vim /etc/chrony.conf
allow 10.0.0.0/24
计算节点：
[root@computer1 /]# yum install chrony -y
[root@computer1 /]# vim /etc/chrony.conf
server 10.0.0.11 iburst
控制节点和计算节点：
[root@computer1 /]# systemctl restart chronyd.service
（4）安装openstack客户端和selinux（控制节点和计算节点）
[root@computer1 /]# yum install python-openstackclient.noarch openstack-selinux.noarch
（5）安装配置mariadb(仅仅控制节点)
[root@controller /]# yum install mariadb mariadb-server.x86_64 python2-PyMySQL.noarch
[root@controller /]# cat >> /etc/my.cnf.d/openstack.cnf << EOF
> [mysqld]
> bind-address = 10.0.0.11
> default-storage-engine = innodb
> innodb_file_per_table
> max_connections = 4096
> collation-server = utf8_general_ci
> character-set-server = utf8
> EOF
[root@controller /]#
[root@controller /]# systemctl start mariadb.service
[root@controller /]# systemctl status mariadb.service
[root@controller /]# systemctl enable mariadb
mysql优化配置：
[root@controller /]# mysql_secure_installation
（6）安装rabbitmq并创建用户(仅仅控制节点)
[root@controller /]# yum install rabbitmq-server.noarch -y
[root@controller /]# systemctl start rabbitmq-server.service
[root@controller /]# systemctl status rabbitmq-server.service
[root@controller /]# systemctl enable rabbitmq-server.service
[root@controller /]# rabbitmq-plugins enable rabbitmq_management
[root@controller /]# rabbitmqctl add_user openstack RABBIT_PASS
Creating user "openstack" ...
[root@controller /]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
Setting permissions for user "openstack" in vhost "/" ...
[root@controller /]# rabbitmq-plugins enable rabbitmq_management
（7）安装缓存memcached（仅仅控制节点）：
[root@controller /]# yum install memcached.x86_64 python-memcached.noarch -y
[root@controller /]# vim /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l 10.0.0.11,::1"
[root@controller /]# systemctl start memcached.service
[root@controller /]# systemctl enable memcached.service
（四）安装openstack认证服务keystone
（1）keystone概念
①keystone的主要功能：认证管理，授权管理和服务目录认证：也可以理解成账号管理，openstack所有的用户，都是在keystone上注册的。
②授权: glance,nova,neutron,cinder等其他服务都统一使用keystone的账号管理，就像现在很多网站支持qq登陆是一样的。
③服务目录：每增加一个服务，都需要在keystone上做注册登记，用户通过keystone可以知道由有那些服务，这么服务的url地址是多少，然后用户就可以直接访问这些服务。
（2）keystone认证服务
①创库授权
数据库授权命令：
grant 权限 on 数据库对象 to 用户
grant 权限 on 数据库对象 to 用户 identified by ‘密码'
[root@controller ~]# mysql
MariaDB [(none)]> CREATE DATABASE keystone;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
-> IDENTIFIED BY 'KEYSTONE_DBPASS';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
-> IDENTIFIED BY 'KEYSTONE_DBPASS';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]>
②安装keystone相关软件包
php,nginx +fastcgi --->php #通过fastcgi 使得nginx去连接php
python,httpd +wsgi--->python #通过wsgi 使得http连接python
[root@controller ~]# yum install openstack-keystone httpd mod_wsgi -y
③修改配置文件
[root@controller ~]# \cp /etc/keystone/keystone.conf{,.bak}
[root@controller ~]# grep -Ev '^$|#' /etc/keystone/keystone.conf.bak >/etc/keystone/keystone.conf
[root@controller ~]# vim /etc/keystone/keystone.conf
方法1:
定义初始管理令牌的值
[DEFAULT]
admin_token = ADMIN_TOKEN
配置数据库访问
[database]
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone
配置Fernet UUID令牌的提供者
[token]
provider = fernet
方法2：
[root@controller keystone]# yum install openstack-utils -y #openstack-utils插件，OpenStack-config命令行配置
openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_token ADMIN_TOKEN
openstack-config --set /etc/keystone/keystone.conf database connection mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone
openstack-config --set /etc/keystone/keystone.conf token provider fernet
③同步数据库
su -s /bin/sh -c "keystone-manage db_sync" keystone #su切换的是keystone用户，使用/bin/sh执行命令 keystone-manage db_sync命令。
-s:表示解释器
-c:表示要执行的命令
keystone：是数据库用户名
[root@controller keystone]# su -s /bin/sh -c "keystone-manage db_sync" keystone
检查表：
[root@controller keystone]# mysql keystone -e "show tables"
查看同步日志：
[root@controller keystone]# vim /var/log/keystone/keystone.log
④初始化fernet
[root@controller keystone]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
[root@controller keystone]# ll /etc/keystone/
drwx------ 2 keystone keystone 24 Jan 4 22:32 fernet-keys
⑤配置httpd(apachd)
优化启动速度：
[root@controller keystone]# echo "ServerName controller" >>/etc/httpd/conf/httpd.conf
[root@controller keystone]# vim /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}
WSGIProcessGroup keystone-public
WSGIScriptAlias / /usr/bin/keystone-wsgi-public
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
Require all granted
</Directory>
</VirtualHost>
<VirtualHost *:35357>
WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-admin
WSGIScriptAlias / /usr/bin/keystone-wsgi-admin
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
Require all granted
</Directory>
</VirtualHost>
[root@controller keystone]#
检验：
[root@controller keystone]# md5sum /etc/httpd/conf.d/wsgi-keystone.conf
8f051eb53577f67356ed03e4550315c2 /etc/httpd/conf.d/wsgi-keystone.conf

（4）计算服务nova
nova服务是openstack云计算中的最核心服务。
常用组件：
nova-api:接受并响应所有的计算服务请求，管理虚拟机(云主机)生命周期
nova-compute（多个）：真正管理虚拟机的生命周期
nova-scheduler： nova调度器（挑选出最合适的nova-compute来创建虚机）
nova-conductor： 帮助nova-compute代理修改数据库中虚拟机的状态
nova-network : 早期openstack版本管理虚拟机的网络（已弃用，neutron）
nova-consoleauth : 为web版的vnc提供访问令牌
tokennovncproxy：web版 vnc客户端
nova-api-metadata：接受来自虚拟机发送的元数据请求
openstack通用配置流程：
a：数据库创库授权
b：在keystone创建系统用户关联角色
c:在keystone上创建服务，注册api
d：安装相应服务软件包
e：修改相应服务的配置文件
f：同步数据库
g：启动服务
在控制节点上：
①数据库创库授权
[root@controller ~]# mysql
CREATE DATABASE nova_api;
CREATE DATABASE nova;
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \
IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \
IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \
IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \
IDENTIFIED BY 'NOVA_DBPASS';
②在keystone创建系统用户(glance,nova,neutron)关联角色
openstack user create --domain default \
--password NOVA_PASS nova
openstack role add --project service --user nova admin
③在keystone上创建服务和注册api
openstack service create --name nova \
--description "OpenStack Compute" compute
openstack endpoint create --region RegionOne \
compute public http://controller:8774/v2.1/%\(tenant_id\)s
openstack endpoint create --region RegionOne \

（5）网络服务neutron
概念介绍
OpenStack Networking（neutron），允许创建、附加网卡设备，这些设备由其他的OpenStack服务管理。插件式的实现可以容纳不同的网络设备和软件，为OpenStack架构与部署提供了灵活性。
常用组件：
neutron-server :接受和响应外部的网络管理请求
neutron-linuxbridge-agent:负责创建桥接网卡
neutron-dhcp-agent：负责分配IP
neutron-metadata-agent：配合nova-metadata-api实现虚拟机的定制化操作
L3-agent:实现三层网络vxlan(网络层)
①数据库授权
[root@controller ~]# mysql
CREATE DATABASE neutron;
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \
IDENTIFIED BY 'NEUTRON_DBPASS';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \
IDENTIFIED BY 'NEUTRON_DBPASS';
②在keystone创建系统用户(glance,nova,neutron)关联角色
openstack user create --domain default --password NEUTRON_PASS neutron
openstack role add --project service --user neutron admin
③在keystone上创建服务和注册api
openstack service create --name neutron \
--description "OpenStack Networking" network
openstack endpoint create --region RegionOne \
network public http://controller:9696
openstack endpoint create --region RegionOne \
network internal http://controller:9696
openstack endpoint create --region RegionOne \
network admin http://controller:9696

③启动服务
[root@computer1 ~]# systemctl start httpd.service
④使用浏览器http://10.0.0.31/dashboard,
⑤如果出现Internal Server Error
解决办法：
[root@computer1 ~]# vim /etc/httpd/conf.d/openstack-dashboard.conf
在WSGISocketPrefix run/wsgi后一行添加：
WSGIApplicationGroup %{GLOBAL}
[root@computer1 ~]# systemctl restart httpd.service
⑥登录dashboard
域：default
用户名:admin
密码:ADMIN_PASS
（五）启动一个实例
第一次启动实例需要步骤：
1：创建openstack网络
2: 创建实例的硬件配置方案
3：创建密钥对（控制节点免秘钥登录）
4：创建安全组规则
5：启动一个实例（通过命令行创建实例，或者通过web页面启动实例）
（1）通过命令行创建实例
①创建网络
neutron net-create --shared --provider:physical_network provider \
--provider:network_type flat oldboy
# physical_network provider,这里的名称相同与：
#[root@controller ~]# cat /etc/neutron/plugins/ml2/ml2_conf.ini | grep flat_networks
#flat_networks = provider
创建子网：
neutron subnet-create --name oldgirl \
--allocation-pool start=10.0.0.101,end=10.0.0.250 \
--dns-nameserver 223.5.5.5 --gateway 10.0.0.254 \
oldboy 10.0.0.0/24
②配置硬件配置方案：
查看已有配置方案：
[root@controller ~]# openstack flavor list
[root@controller ~]# openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano
③创建秘钥对
[root@controller ~]# ssh-keygen -q -N "" -f ~/.ssh/id_rsa
[root@controller ~]# openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
④创建安全组规则
openstack security group rule create --proto icmp default
openstack security group rule create --proto tcp --dst-port 22 default
⑤启动一个实例：
查看已有镜像：
[root@controller ~]# openstack image list
查看网络id：
[root@controller ~]# neutron net-list
dd7500f9-1cb1-42df-8025-a232ef90d54c
openstack server create --flavor m1.nano --image cirros \
--nic net-id=dd7500f9-1cb1-42df-8025-a232ef90d54c --security-group default \
--key-name mykey oldboy
检查：
[root@controller images]# openstack server list
[root@controller images]# nova list
注意：
①出现controller无法解析，在电脑的hosts文件中添加：10.0.0.11 controller
②如果实例卡在gurb界面
计算节点修改配置：
vim /etc/nova/nova.conf
[libvirt]
cpu_mode = none
virt_type = qemu
[root@computer1 ~]# systemctl restart openstack-nova-compute
（2）web页面创建实例
①点击“计算”
②点击“实例”
③点击右上角“启用实例”
④详情信息：instance name ：实例名称，count：选择创建实例数量
⑤选择镜像源，点击加号
⑥flavor：实例的硬件配置，选择点击后端加号
⑦网络选择已经创建的，默认的
⑧下面都是默认
（六）增加一个计算节点
（1）增加计算节点的步骤
1：配置yum源
2: 时间同步
3：安装openstack基础包
4：安装nova-compute
5：安装neutron-linuxbridge-agent
6：启动服务nova-compute和linuxbridge-agent
7：验证
（2）安装yum
mount /dev/cdrom /mnt
rz 上传openstack_rpm.tar.gz到/opt，并解压
生成repo配置文件
echo '[local]
name=local
baseurl=file:///mnt
gpgcheck=0
[openstack]
name=openstack
baseurl=file:///opt/repo
gpgcheck=0' >/etc/yum.repos.d/local.repo
yum makecache
echo 'mount /dev/cdrom /mnt' >>/etc/rc.local
chmod +x /etc/rc.d/rc.local
（3）时间同步和openstack基础包
时间同步：
vim /etc/chrony.conf
修改第3行为
server 10.0.0.11 iburst
systemctl restart chronyd

（5）启动服务
[root@computer2 /]# systemctl start libvirtd openstack-nova-compute neutron-linuxbridge-agent
[root@computer2 /]# systemctl status libvirtd openstack-nova-compute neutron-linuxbridge-agent
（6）创建虚机来检查新增的计算节点是否可用
①创建主机聚集：管理员-主机聚集-创建主机聚集-主机聚集信息（名称，域：oldboyboy）-管理聚集内主机（compute2）--创建
②创建主机：项目-实例-启动实例-详细信息（可用区域选择刚创建的oldobyboy）-源-flavor-网络-网络端口-安全组-秘钥对-配置-元数据-创建
注意：如果实例卡在gurb界面
vim /etc/nova/nova.conf
[libvirt]
cpu_mode = none
virt_type = qemu
systemctl restart openstack-nova-compute
（七）openstack用户项目和角色关系
（1）项目用户角色的关系图
创建域
openstack domain create --description "Default Domain" default
创建项目
openstack project create --domain default --description "Admin Project" admin
创建用户
openstack user create --domain default --password ADMIN_PASS admin
创建角色
openstack role create admin
关联角色，授权
openstack role add --project admin --user admin admin
（2）身份管理里创建角色（admin，user）
①先创建角色
②创建项目
调整配额，在项目里调整。
③创建用户
普通用户里无管理员目录
admin角色：所有项目管理员
user角色：单个项目的用户
只用管理员才能看到所有实例。
（八）迁移glance镜像服务
（1）背景
当openstack管理的计算节点越来越多的时候，控制节点的压力越来越大，由于所有的服务都安装在控制节点，这时候控制节点上的openstack服务随时都团灭的风险。
大家都知道openstack是基于soa架构设计的，我们已经实现了horizon的迁移，接下来，我们实现glance镜像服务的迁移，后面其他的服务都可以迁移，让控制节点只保留一个keystone服务，是soa架构的最佳实践。
本次，我们将glance镜像服务，由控制节点迁移到compute2上。
（2）glance镜像服务迁移的主要步骤
1：停止控制节点上的glance服务
2：备份迁移glance数据库
3：在新的节点上安装配置glance
4：迁移原有glance镜像文件
5：修改keystone中glance的api地址
6：修改所有节点nova配置文件中glance的api地址
7：测试，上传镜像，创建实例
（3）操作过程
①控制节点上关闭相关服务：
[root@controller ~]# systemctl stop openstack-glance-api.service openstack-glance-registry.service
[root@controller ~]# systemctl disable openstack-glance-api.service openstack-glance-registry.service
②在控制节点上备份库：
[root@controller ~]# mysqldump -uroot -B glance >glance.sql
[root@controller ~]# scp glance.sql 10.0.0.32:/root
（4）数据库迁移
在compute2上：
yum install mariadb-server.x86_64 python2-PyMySQL -y
systemctl start mariadb
systemctl enable mariadb
mysql_secure_installation
导入从控制节点上备份的glance数据库
mysql < glance.sql
[root@computer2 ~]# mysql
mysql>
show databases;
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
IDENTIFIED BY 'GLANCE_DBPASS';
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
IDENTIFIED BY 'GLANCE_DBPASS';
（5）安装glance服务
在compute2上安装：
yum install openstack-glance -y
在控制节点上将配置文件发送至compute2上：
[root@controller ~]# scp /etc/glance/glance-api.conf 10.0.0.32:/etc/glance/
[root@controller ~]# scp /etc/glance/glance-registry.conf 10.0.0.32:/etc/glance/
修改：
connection = mysql+pymysql://glance:GLANCE_DBPASS@10.0.0.32/glance
复制之前的内容，注意：修改数据库的ip地址为10.0.0.32
systemctl start openstack-glance-api.service openstack-glance-registry.service
systemctl enable openstack-glance-api.service openstack-glance-registry.service
（6）迁移镜像
[root@computer2 glance]# scp -rp 10.0.0.11:/var/lib/glance/images/* /var/lib/glance/images/
[root@computer2 images]# chown -R glance:glance /var/lib/glance/images/
在控制节点上检查：
source admin-openrc
openstack endpoint list | grep image
依旧是之前的镜像
（7）修改keystone上的glance的api地址
在控制节点上：
查看相关数据库：
msyql keystone:
select * from endpoint
[root@controller ~]# mysqldump -uroot keystone endpoint >endpoint.sql
[root@controller ~]# cp endpoint.sql /opt/
修改数据库配置文件：
[root@controller ~]# sed -i 's#http://controller:9292#http://10.0.0.32:9292#g' endpoint.sql
导入修改好的数据库文件：
[root@controller ~]# mysql keystone < endpoint.sql
查看glance接口地址：
[root@controller ~]# openstack endpoint list|grep image
[root@controller ~]# openstack image list
（8）修改所有节点nova配置文件
sed -i 's#http://controller:9292#http://10.0.0.32:9292#g' /etc/nova/nova.conf
grep '9292' /etc/nova/nova.conf
systemctl restart openstack-nova-api.service openstack-nova-compute.service
控制节点重启：openstack-nova-api.service
计算节点重启：openstack-nova-compute.service
控制节点：
[root@controller ~]# nova service-list
+----+------------------+------------+-----------+---------+-------+----------------------------+-----------------+
| Id | Binary | Host | Zone | Status | State | Updated_at | Disabled Reason |
+----+------------------+------------+-----------+---------+-------+----------------------------+-----------------+

| 2 | nova-consoleauth | controller | internal | enabled | up | 2020-01-05T16:53:10.000000 | - |
| 3 | nova-scheduler | controller | internal | enabled | up | 2020-01-05T16:53:10.000000 | - |
| 6 | nova-compute | computer1 | nova | enabled | up | 2020-01-05T16:53:08.000000 | - |
| 7 | nova-compute | computer2 | oldboyboy | enabled | up | 2020-01-05T16:53:08.000000 | - |
+----+------------------+------------+-----------+---------+-------+----------------------------+-----------------+
（9）测试，上传镜像，创建实例
上传镜像：
项目-镜像-创建镜像
创建实例：
项目-实例-启用实例
web页面；项目里可以上传镜像
qemu-img info .. #查看镜像信息
（10）安装cinder块服务
①块存储服务cinder的介绍
块存储服务（cinder）为实例提供块存储。存储的分配和消耗是由块存储驱动器，或者多后端配置的驱动器决定的。还有很多驱动程序可用：NAS/SAN，NFS，LVM，Ceph等。常用组件：cinder-api: 接收和响应外部有关块存储请求c
inder-volume： 提供存储空间
cinder-scheduler：调度器，决定将要分配的空间由哪一个cinder-volume提供。
cinder-backup： 备份卷
②openstack服务通用安装步骤
a：数据库创库授权
b：在keystone创建系统用户关联角色
c：在keystone上创建服务，注册api
d：安装相应服务软件包
e：修改相应服务的配置文件
f：同步数据库
g：启动服务
③cinder块存储服务控制节点
数据库创库授权
[root@controller ~]# mysql
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
IDENTIFIED BY 'CINDER_DBPASS';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \
IDENTIFIED BY 'CINDER_DBPASS';
在keystone创建系统用户(glance,nova,neutron,cinder)关联角色
openstack user create --domain default --password CINDER_PASS cinder
openstack role add --project service --user cinder admin
在keystone上创建服务和注册api(source admin-openrc )
openstack service create --name cinder \
--description "OpenStack Block Storage" volume
openstack service create --name cinderv2 \
--description "OpenStack Block Storage" volumev2
openstack endpoint create --region RegionOne \

⑥启动应用程序
systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service
⑦在控制节点上检测
[root@controller ~]# cinder service-list
⑧创建卷，验证：
项目-计算-卷-创建卷；在计算节点1上lvs查看创建成功的卷。
⑨挂卷：
步骤一：卷-编辑卷-管理连接-挂至相应实例；
步骤二：在相应的实例上查看：
sudo su
fdisk -l
步骤三：格式化新增的卷并挂载：
mkfs.ext4 /dev/vdb
mount /dev/vdb /mnt
df -h
⑩扩容卷
步骤一：
unmount /mnt
步骤二：
项目-计算-卷-编辑卷-卷管理-分离卷
项目-计算-卷-编辑卷-卷管理-编辑卷-扩展卷（2g，computer1：lvs）
项目-计算-卷-编辑卷-卷管理-编辑卷-管理卷-挂至相应的实例
实例控制台：
mount /dev/vdb /mnt
df -h
resize2fs /dev/vdb
df -h
查看存储信息：
[root@computer1 ~]# vgs
⑪创卷卷组类型
已定义卷组类型：
volume_backend_name = ssd
volume_backend_name = sata
管理员-卷-创建类型卷-名称-查看卷类型-已创建-分别在键和值里填写以上信息。
项目-卷-创建卷-创建卷过程中可以选择已经创建好的卷类型。lvs查看创建情况
（12）增加一个flat网络
分别在三台机器上增加一个网卡，选择lan网段，地址172.16.0.0/24
①增加一个flat网络原因
我们的openstack当前环境只有一个基于eth0网卡桥接的，它能使用的ip范围有限，就决定着它能创建的实例数量有限，无法超过可用ip的数量，当我们的openstack私有云规模比较大的时候，这时候只有一个网络，就不能满足我们的需求了，所以这里我们来学习如何增加一个网络我们使用的环境是VMware workstation，无法模拟vlan的场景，所以这里我们继续使用flat，网络类型。
②添加网卡eth1
分别虚拟机上添加一块网卡，为lan区段，172.16.0.0/24
拷贝ifcfg-eth0 至ifcfg-eth1,修改eth1的地址为172.16.0.0/24地址段，并ifup eth1启动网卡。
[root@computer1 network-scripts]# scp ifcfg-eth1 10.0.0.11:pwd
③控制节点配置
1:控制节点
a:
vim /etc/neutron/plugins/ml2/ml2_conf.ini
[ml2_type_flat]
flat_networks = provider,net172_16
b:
vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = provider:eth0,net172_16:eth1
c：重启
systemctl restart neutron-server.service neutron-linuxbridge-agent.service
④计算节点配置
a:
vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = provider:eth0,net172_16:eth1
b：重启
systemctl restart neutron-linuxbridge-agent.service
检测：控制节点
neutron agent-list
⑤创建网络
命令行创建：
neutron net-create --shared --provider:physical_network net172_16 \
--provider:network_type flat net172_16
neutron subnet-create --name oldgirl \
--allocation-pool start=172.16.0.1,end=172.16.0.250 \
--dns-nameserver 223.5.5.5 --gateway 172.16.0.254 \
net172_16 172.16.0.0/24
web页面创建网络：
管理员-网络-创建网络（供应商，平面）-创建子网
创建实例：项目-实例-创建实例（创建过程中可以选择刚创建的网络）
注意：创建一个linux系统作为路由器使用：
基于net172_16网络上网，路由器服务器需要配置：
配置eth0和eth1,但是eth1的网络地址为172.16.0.254,为虚拟机网关地址，不配置网关。
编辑内核配置文件，开启转发
vim /etc/sysctl.conf
net.ipv4.ip_forward = 1
使内核生效
sysctl -p
清空防火墙的filter表
iptables -F
#添加转发规则
iptables -t nat -A POSTROUTING -s 172.16.0.0/24 -j MASQUERADE
（13）cinder对接nfs共享存储
①cinder使用nfs做后端存储
cinder服务和nova服务很相似
nova：不提供虚拟化，支持多种虚拟化技术，kvm,xen,qemu,lxc
cinder：不提供存储，支持多种存储技术，lvm，nfs，glusterFS，ceph
后期如果需要对接其他类型后端存储，方法都类似。
②前提条件控制节点安装nfs
安装
[root@controller ~]# yum install nfs-utils.x86_64 -y
配置
[root@controller ~]# mkdir /data
[root@controller ~]# vim /etc/exports
/data 10.0.0.0/24(rw,async,no_root_squash,no_all_squash)
启动
[root@controller ~]# systemctl restart rpcbind.socket
[root@controller ~]# systemctl restart nfs
③存储节点的配置
[root@computer1 ~]# yum install nfs -y
修改/etc/cinder/cinder.conf
[DEFAULT]
enabled_backends = sata,ssd,nfs
[nfs]
volume_driver = cinder.volume.drivers.nfs.NfsDriver
nfs_shares_config = /etc/cinder/nfs_shares
volume_backend_name = nfs
vi /etc/cinder/nfs_shares
10.0.0.11:/data
[root@computer1 ~]# showmount -e 10.0.0.11
Export list for 10.0.0.11:
/data 10.0.0.0/24
重启cinder-volume
systemctl restart openstack-cinder-volume.service
在控制节点上检查：cinder service-list
查看卷日志：
[root@computer1 ~]# vim /var/log/cinder/volume.log
有事报错,需要：
[root@computer1 ~]# chown -R cinder:cinder /var/lib/cinder/mnt/
④穿件卷，挂载实例
管理员-卷-创建类型卷-查看extra spec，设置键和值
项目-卷-创建卷-管理连接-连接到实例

（14）openstack云主机的冷迁移
①前提条件
前提条件：
1.至少有2个计算节点
2.2个计算节点必须处于同一个可用区域
3.计算节点，有足够的剩余计算资源
②配置计算节点nova用户互信
所有计算节点

计算节点2：
计算节点1是以root发送的，所以在计算节点1上都是root用户属主：
[root@computer1 ~]# chown -R nova:nova /var/lib/nova
控制节点配置：
[root@controller ~]# vim /etc/nova/nova.conf
[DEFAULT]
cheduler_default_filters=RetryFilter,AvailabilityZoneFilter,RamFilter,DiskF
ilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerG
roupAntiAffinityFilter,ServerGroupAffinityFilter
[root@controller ~]# systemctl restart openstack-nova-scheduler.service
[root@controller ~]# systemctl status openstack-nova-scheduler.service
两个计算节点配置：
[root@computer1 ~]# vim /etc/nova/nova.conf
[DEFAULT]
allow_resize_to_same_host = True
[root@computer1 ~]# systemctl restart openstack-nova-compute.service
[root@computer1 ~]# systemctl status openstack-nova-compute.service
创建实例：
项目-实例-创建实例
管理员-实例-编辑实例-迁移实例。
（15）openstack新建云主机流程
流程图要说清楚。
（16）openstack定制云主机
思考：为什么基于同一个镜像模板启动的云主机，云主机的主机名和实例名称一样？
思考：为什么在控制节点上可以免密码登陆我们的云主机？
思考：控制节点nova的配置文件中，需要配置下面红色标记的两行？
vi /etc/nova/nova.com
......
[neutron]
url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = NEUTRON_PASS
service_metadata_proxy = True
metadata_proxy_shared_secret = METADATA_SECRET
思考：为什么neutron-metadata和dhcp-agent要配置以下内容？
vi /etc/neutron/metadata_agent.ini
[DEFAULT]
nova_metadata_ip = controller
metadata_proxy_shared_secret = METADATA_SECRET
vi /etc/neutron/dhcp_agent.ini
[DEFAULT]
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = True
[root@controller ~]# ssh cirros@10.0.0.111

[root@controller ~]# ip a
[root@controller ~]# netstat -lntp
[root@controller ~]# ps -ef | grep 19193
（17）openstack三层网络vxlan
思考：为什么现在的公有云买的云主机，使用公网ip地址连接后，看到的却是一个私网ip？
思考：公有云上每一个用户都可以建立多个vpc网络，云厂商如何实现这么多vpc网络的隔离？
使用vlan的话，最多产生1-4094个隔离的网络
使用vxlan的话，最多产生4096*4096-2约等于1678万个隔离的网络
①为所有节点，增加一块网卡，作为vxlan网络的隧道通信ip
三层网络vxlan控制节点配置步骤1
[root@controller ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth2
TYPE=Ethernet
BOOTPROTO=none
NAME=eth2
DEVICE=eth2
ONBOOT=yes
IPADDR=172.16.1.11
NETMASK=255.255.255.0
GATEWAY=172.16.1.254
DNS1=223.5.5.5
[root@controller ~]#ifup eth2
②三层网络vxlan控制节点配置步骤2
修改控制节点/etc/neutron/neutron.conf文件
[DEFAULT]
...
core_plugin = ml2
service_plugins =
修改为：
[root@controller ~]# vim /etc/neutron/neutron.conf
[DEFAULT]
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True
③三层网络vxlan控制节点配置步骤3
将/etc/neutron/plugins/ml2/ml2_conf.ini修改为
[DEFAULT]
[ml2]
type_drivers = flat,vlan,vxlan
tenant_network_types = vxlan
mechanism_drivers = linuxbridge,l2population
extension_drivers = port_security
[ml2_type_flat]
flat_networks = provider,net172_16
[ml2_type_geneve]
[ml2_type_gre]
[ml2_type_vlan]
[ml2_type_vxlan]
vni_ranges = 1:100000
[securitygroup]
enable_ipset = True
④三层网络vxlan控制节点配置步骤4
将/etc/neutron/plugins/ml2/linuxbridge_agent.ini修改为
[DEFAULT]
[agent]
[linux_bridge]
physical_interface_mappings = provider:eth0,net172_16:eth1
[securitygroup]
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
[vxlan]
enable_vxlan = True
local_ip = 172.16.1.11
l2_population = True
⑤三层网络vxlan控制节点配置步骤5
将/etc/neutron/l3_agent.ini修改为
[DEFAULT]
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
external_network_bridge =
[AGENT]
启动服务：
systemctl restart neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
systemctl enable neutron-l3-agent.service
systemctl start neutron-l3-agent.service
⑥计算节点：三层网络vxlan计算节点配置步骤
将/etc/neutron/plugins/ml2/linuxbridge_agent.ini修改为
[DEFAULT]
[agent]
[linux_bridge]
physical_interface_mappings = provider:eth0,net172_16:eth1
[securitygroup]
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
[vxlan]
enable_vxlan = True
local_ip = 172.16.1.31
l2_population = True
systemctl restart neutron-linuxbridge-agent.service
在控制节点查看：
[root@controller ~]# neutron agent-list
⑦web界面操作
步骤1：修改oldboy外网为外部网络。管理员-网络-oldbly-编辑网络-修改为外部网络
步骤2：创建一个内部测试网络。项目-网络-创建网络（test，192.168.1.0/24）
步骤3：开启外部网络的路由功能。在computer1上：
[root@computer1 ~]# vim /etc/openstack-dashboard/local_settings
OPENSTACK_NEUTRON_NETWORK = {
'enable_router': True,
重启apache：
[root@computer1 ~]# systemctl restart httpd
在web页面中：网络中，多了一个路由器。
步骤4：使用oldboy用户创建一个网络。项目-网络-创建网络（test内部网络）
步骤5：使用oldboy用户创建一个路由器。项目-网络-路由器（testr）,在路由器添加接口外部和内部接口。
步骤6:admin用户创建两个实例，使用内部网络创建，ping www.baidu.com
