OpenStack Ocata 超详细搭建文档

2022-06-14 02:11:20

前言搭建前必须看我
本文档搭建的是分布式O版openstack（controller+ N compute + 1 cinder）的文档。
openstack版本为Ocata。

搭建的时候，请严格按照文档所描写的进行配置，在不熟悉的情况下，严禁自己添加额外的配置和设置！
学习这个文档能搭建基本的openstack环境，切记千万不能用于生产！要用于生产的环境，必须有严格的
测试还有额外的高级配置！

文档版权属于DevOps运维，未经允许，严禁售卖、复制传播！

阅读文档注意，红色的部分是重要提示，另外其他加颜色的字体参数也要额外注意！
有些命令很长，注意有换行了，别只敲一半，每条命令前面都带有 #。

一、环境准备

1. 前提准备
安装vmware workstation12.5.0，虚拟出三台配置至少CPU 4c MEM 4G的虚拟机

Controller节点和Compute节点配置：
CPU:4c
MEM:4G
Disk:200G
Network: 3 (eth0 eth1 eth2，第一块网卡就是extenel的网卡，第二块网卡是admin网卡，第三块是tunnel隧道)

Cinder节点配置：
CPU:4c
MEM:4G
Disk:200G+50G（这个50G可以根据自己需求调整大小）
Network: 2 (eth0 eth1，第一块网卡就是extenel的网卡，第二块网卡是admin网卡，cinder节点不需要隧道)

安装CentOS7.2系统（最小化安装系统，不要yum update升级到7.3！Ocata版7.3下依然有虚拟机启动出现iPXE启动问题） + 关闭防火墙 + 关闭selinux
# systemctl stop firewalld.service
# systemctl disable firewalld.service

安装好相关工具，因为系统是最小化安装的，所以一些ifconfig vim等命令没有，运行下面的命令把它们装上：
# yum install net-tools wget vim ntpdate bash-completion -y

2. 更改hostname
# hostnamectl set-hostname controller

如果是compute就运行：
# hostnamectl set-hostname compute1
cinder节点就运行：
# hostnamectl set-hostname cinder

然后每个节点配置/etc/hosts文件如下
10.1.1.150 controller
10.1.1.151 compute1
10.1.1.152 cinder

3. NTP同步系统时间
# ntpdate cn.pool.ntp.org
然后查看运行date命令查看时间是否同步成功
注意，这个操作很重要，openstack是分布式架构的，每个节点都不能有时间差！
很多同学刚装完centos系统，时间会跟当前北京的时间不一致，所以必须运行下这个命令！
另外，也把这个命令加到开机启动里面去
# echo "ntpdate cn.pool.ntp.org" >> /etc/rc.d/rc.local
# chmod +x /etc/rc.d/rc.local

4. 配置IP 网络配置规划
网络配置：
external : 9.110.187.0/24
admin mgt : 10.1.1.0/24
tunnel：10.2.2.0/24
storage：10.3.3.0/24 （我们环境没有，如果你集成了ceph就应该用到）

controller虚拟机第一块网卡external，请配置IP 9.110.187.150
第二块网卡admin，请配置IP 10.1.1.150
第三块网卡tunnel，请配置IP 10.2.2.150

compute1虚拟机第一块网卡external，请配置IP 9.110.187.151
第二块网卡admin，请配置IP 10.1.1.151
第三块网卡tunnel，请配置IP 10.2.2.151

cinder虚拟机第一块网卡external，请配置IP 9.110.187.152
第二块网卡admin，请配置IP 10.1.1.152
第三块网卡tunnel，请配置IP 10.2.2.152

三个网络解释：
1. external : 这个网络是链接外网的，也就是说openstack环境里的虚拟机要让用户访问，那必须有个网段是连外网的，用户通过这个网络能访问到虚拟机。如果是搭建的公有云，这个IP段一般是公网的（不是公网，你让用户怎么访问你的虚拟机？）
2. admin mgt：这个网段是用来做管理网络的。管理网络，顾名思义，你的openstack环境里面各个模块之间需要交互，连接数据库，连接Message Queue都是需要一个网络去支撑的，那么这个网段就是这个作用。最简单的理解，openstack自己本身用的IP段。
3. tunnel : 隧道网络，openstack里面使用gre或者vxlan模式，需要有隧道网络；隧道网络采用了点到点通信协议代替了交换连接，在openstack里，这个tunnel就是虚拟机走网络数据流量用的。

当然这3个网络你都放在一块也行，但是只能用于测试学习环境，真正的生产环境是得分开的。在自己学习搭建的时候，通常我们用的是vmware workstation虚拟机，有些同学创建虚拟机后，默认只有一块网卡，有些同学在只有一块网卡就不知道如何下手了，一看有三种网络就晕乎了... 所以，在创建完虚拟机后，请给虚拟机再添加2块网卡，根据生产环境的要求去搭建学习。

三种网络在生产环境里是必须分开的，有的生产环境还有分布式存储，所以还得额外给存储再添加一网络，storage段。网络分开的好处就是数据分流、安全、不相互干扰。你想想，如果都整一块了，还怎么玩？用户访问虚拟机还使用你openstack的管理段，那太不安全了...

5. 搭建OpenStack内部使用源
关于内部源的搭建，请看视频。

二、搭建Mariadb

1. 安装mariadb数据库
# yum install -y MariaDB-server MariaDB-client

2. 配置mariadb
# vim /etc/my.cnf.d/mariadb-openstack.cnf

在mysqld区块添加如下内容：
[mysqld]
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
init-connect = 'SET NAMES utf8'
character-set-server = utf8
bind-address = 10.1.1.150

3、启动数据库及设置mariadb开机启动
# systemctl enable mariadb.service
# systemctl restart mariadb.service
# systemctl status mariadb.service
# systemctl list-unit-files |grep mariadb.service

4. 配置mariadb，给mariadb设置密码
# mysql_secure_installation
先按回车，然后按Y，设置mysql密码，然后一直按y结束
注意，全篇博文我们设置的密码都是devops，大家可以自行更改！

三、安装RabbitMQ

1. 每个节点都安装erlang
# yum install -y erlang

2. 每个节点都安装RabbitMQ
# yum install -y rabbitmq-server

3. 每个节点都启动rabbitmq及设置开机启动
# systemctl enable rabbitmq-server.service
# systemctl restart rabbitmq-server.service
# systemctl status rabbitmq-server.service
# systemctl list-unit-files |grep rabbitmq-server.service

4. 创建openstack，注意将PASSWOED替换为自己的合适密码（本文全部都是devops为密码）
# rabbitmqctl add_user openstack devops

5. 将openstack用户赋予权限
# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
# rabbitmqctl set_user_tags openstack administrator
# rabbitmqctl list_users

6. 看下监听端口 rabbitmq用的是5672端口
# netstat -ntlp |grep 5672

7. 查看RabbitMQ插件
# /usr/lib/rabbitmq/bin/rabbitmq-plugins list

8. 打开RabbitMQ相关插件
# /usr/lib/rabbitmq/bin/rabbitmq-plugins enable rabbitmq_management mochiweb webmachine rabbitmq_web_dispatch amqp_client rabbitmq_management_agent

打开相关插件后，重启下rabbitmq服务
systemctl restart rabbitmq-server

浏览器输入：http://9.110.187.150:15672 默认用户名密码：guest/guest
通过这个界面，我们能很直观的看到rabbitmq的运行和负载情况

9. 查看rabbitmq状态
用浏览器登录http://9.110.187.150:15672 输入openstack/devops本文档搭建的是分布式O版openstack（controller+ N compute + 1 cinder）的文档。
openstack版本为Ocata。也可以查看状态信息：

如果你做好了一个CentOS6.7系统的镜像，也可以用这命令操作，例：
# glance image-create --name "CentOS7.1-x86_64" --file CentOS_7.1.qcow2 --disk-format qcow2 --container-format bare --visibility public --progress

查看镜像列表：
# glance image-list

六、安装配置nova

1、创建nova数据库
CREATE DATABASE nova;
CREATE DATABASE nova_api;
CREATE DATABASE nova_cell0;

2、创建数据库用户并赋予权限
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'devops';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'devops';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'devops';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'devops';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'devops';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'devops';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'controller' IDENTIFIED BY 'devops';
FLUSH PRIVILEGES;

注：查看授权列表信息 SELECT DISTINCT CONCAT('User: ''',user,'''@''',host,''';') AS query FROM mysql.user;
取消之前某个授权 REVOKE ALTER ON *.* TO 'root'@'controller' IDENTIFIED BY 'devops';

3、创建nova用户及赋予admin权限
# source /root/admin-openrc
# openstack user create --domain default nova --password devops
# openstack role add --project service --user nova admin

4、创建computer服务
# openstack service create --name nova --description "OpenStack Compute" compute

5、创建nova的endpoint
# openstack endpoint create --region RegionOne compute public http://controller:8774/v2.1/%\(tenant_id\)s
# openstack endpoint create --region RegionOne compute internal http://controller:8774/v2.1/%\(tenant_id\)s
# openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1/%\(tenant_id\)s

6、安装nova相关软件
# yum install -y openstack-nova-api openstack-nova-conductor openstack-nova-cert openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler

7、配置nova的配置文件/etc/nova/nova.conf
# cp /etc/nova/nova.conf /etc/nova/nova.conf.bak
# >/etc/nova/nova.conf
# openstack-config --set /etc/nova/nova.conf DEFAULT enabled_apis osapi_compute,metadata
# openstack-config --set /etc/nova/nova.conf DEFAULT auth_strategy keystone
# openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 10.1.1.150
# openstack-config --set /etc/nova/nova.conf DEFAULT use_neutron True
# openstack-config --set /etc/nova/nova.conf DEFAULT firewall_driver nova.virt.firewall.NoopFirewallDriver
# openstack-config --set /etc/nova/nova.conf DEFAULT transport_url rabbit://openstack:devops@controller
# openstack-config --set /etc/nova/nova.conf database connection mysql+pymysql://nova:devops@controller/nova
# openstack-config --set /etc/nova/nova.conf api_database connection mysql+pymysql://nova:devops@controller/nova_api
# openstack-config --set /etc/nova/nova.conf scheduler discover_hosts_in_cells_interval -1
# openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_uri http://controller:5000
# openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_url http://controller:35357
# openstack-config --set /etc/nova/nova.conf keystone_authtoken memcached_servers controller:11211
# openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_type password
# openstack-config --set /etc/nova/nova.conf keystone_authtoken project_domain_name default
# openstack-config --set /etc/nova/nova.conf keystone_authtoken user_domain_name default
# openstack-config --set /etc/nova/nova.conf keystone_authtoken project_name service
# openstack-config --set /etc/nova/nova.conf keystone_authtoken username nova
# openstack-config --set /etc/nova/nova.conf keystone_authtoken password devops
# openstack-config --set /etc/nova/nova.conf keystone_authtoken service_token_roles_required True
# openstack-config --set /etc/nova/nova.conf vnc vncserver_listen 10.1.1.150
# openstack-config --set /etc/nova/nova.conf vnc vncserver_proxyclient_address 10.1.1.150
# openstack-config --set /etc/nova/nova.conf glance api_servers http://controller:9292
# openstack-config --set /etc/nova/nova.conf oslo_concurrency lock_path /var/lib/nova/tmp

注意：其他节点上记得替换IP，还有密码，文档红色以及绿色的地方。

8、设置cell（单元格）
关于cell（单元格）的介绍，引用出自于九州云分享的《Ocata组件Nova Cell V2 详解》& 有云的《引入Cells功能最核心要解决的问题就是OpenStack集群的扩展性》两篇文章的整合介绍：
OpenStack 在控制平面上的性能瓶颈主要在 Message Queue 和 Database 。尤其是 Message Queue , 随着计算节点的增加，性能变的越来越差，因为openstack里每个资源和接口都是通过消息队列来通信的，有测试表明，当集群规模到了200，一个消息可能要在十几秒后才会响应；为了应对这种情况，引入Cells功能以解决OpenStack集群的扩展性。

同步下nova数据库
# su -s /bin/sh -c "nova-manage api_db sync" nova
# su -s /bin/sh -c "nova-manage db sync" nova

设置cell_v2关联上创建好的数据库nova_cell0
# nova-manage cell_v2 map_cell0 --database_connection mysql+pymysql://root:devops@controller/nova_cell0

创建一个常规cell，名字叫cell1，这个单元格里面将会包含计算节点
# nova-manage cell_v2 create_cell --verbose --name cell1 --database_connection mysql+pymysql://root:devops@controller/nova_cell0 --transport-url rabbit://openstack:devops@controller:5672/
检查部署是否正常
# nova-status upgrade check
创建和映射cell0，并将现有计算主机和实例映射到单元格中
# nova-manage cell_v2 simple_cell_setup
查看已经创建好的单元格列表
# nova-manage cell_v2 list_cells --verbose
注意，如果有新添加的计算节点，需要运行下面命令来发现，并且添加到单元格中
# nova-manage cell_v2 discover_hosts
当然，你可以在控制节点的nova.conf文件里[scheduler]模块下添加 discover_hosts_in_cells_interval=-1 这个设置来自动发现

9、安装placement
从Ocata开始，需要安装配置placement参与nova调度了，不然虚拟机将无法创建！
# yum install -y openstack-nova-placement-api

创建placement用户和placement 服务
# openstack user create --domain default placement --password devops
# openstack role add --project service --user placement admin
# openstack service create --name placement --description "OpenStack Placement" placement

创建placement endpoint
# openstack endpoint create --region RegionOne placement public http://controller:8778
# openstack endpoint create --region RegionOne placement admin http://controller:8778
# openstack endpoint create --region RegionOne placement internal http://controller:8778

把placement 整合到nova.conf里
# openstack-config --set /etc/nova/nova.conf placement auth_url http://controller:35357
# openstack-config --set /etc/nova/nova.conf placement memcached_servers controller:11211
# openstack-config --set /etc/nova/nova.conf placement auth_type password
# openstack-config --set /etc/nova/nova.conf placement project_domain_name default
# openstack-config --set /etc/nova/nova.conf placement user_domain_name default
# openstack-config --set /etc/nova/nova.conf placement project_name service
# openstack-config --set /etc/nova/nova.conf placement username nova
# openstack-config --set /etc/nova/nova.conf placement password devops
# openstack-config --set /etc/nova/nova.conf placement os_region_name RegionOne

配置修改00-nova-placement-api.conf文件，这步没做创建虚拟机的时候会出现禁止访问资源的问题
# cd /etc/httpd/conf.d/
# cp 00-nova-placement-api.conf 00-nova-placement-api.conf.bak
# >00-nova-placement-api.conf
# vim 00-nova-placement-api.conf
添加以下内容：
Listen 8778

<VirtualHost *:8778>
WSGIProcessGroup nova-placement-api
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
WSGIDaemonProcess nova-placement-api processes=3 threads=1 user=nova group=nova
WSGIScriptAlias / /usr/bin/nova-placement-api
<Directory "/">
Order allow,deny
Allow from all
Require all granted
</Directory>
<IfVersion >= 2.4>
ErrorLogFormat "%M"
</IfVersion>
ErrorLog /var/log/nova/nova-placement-api.log
</VirtualHost>

Alias /nova-placement-api /usr/bin/nova-placement-api
<Location /nova-placement-api>
SetHandler wsgi-script
Options +ExecCGI
WSGIProcessGroup nova-placement-api
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
</Location>

重启下httpd服务
# systemctl restart httpd
检查下是否配置成功
# nova-status upgrade check

10、设置nova相关服务开机启动
# systemctl enable openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

启动nova服务：
# systemctl restart openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

查看nova服务：
# systemctl status openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

# systemctl list-unit-files |grep openstack-nova-*

11、验证nova服务
# unset OS_TOKEN OS_URL
# source /root/admin-openrc
# nova service-list
# openstack endpoint list 查看endpoint list
看是否有结果正确输出

七、安装配置neutron

1、创建neutron数据库

# openstack-config --set /etc/neutron/neutron.conf nova password devops
# openstack-config --set /etc/neutron/neutron.conf oslo_concurrency lock_path /var/lib/neutron/tmp

8、配置/etc/neutron/plugins/ml2/ml2_conf.ini
# openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 type_drivers flat,vlan,vxlan
# openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 mechanism_drivers linuxbridge,l2population
# openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 extension_drivers port_security
# openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 tenant_network_types vxlan
# openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 path_mtu 1500
# openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2_type_flat flat_networks provider

# openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup firewall_driver neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

注意eno16777736是连接外网的网卡，一般这里写的网卡名都是能访问外网的，如果不是外网网卡，那么VM就会与外界网络隔离。
local_ip 定义的是隧道网络，vxLan下 vm-linuxbridge->vxlan ------tun-----vxlan->linuxbridge-vm

10、配置 /etc/neutron/l3_agent.ini
# openstack-config --set /etc/neutron/l3_agent.ini DEFAULT interface_driver neutron.agent.linux.interface.BridgeInterfaceDriver
# openstack-config --set /etc/neutron/l3_agent.ini DEFAULT external_network_bridge
# openstack-config --set /etc/neutron/l3_agent.ini DEFAULT debug false

11、配置/etc/neutron/dhcp_agent.ini

# openstack-config --set /etc/neutron/dhcp_agent.ini DEFAULT verbose True
# openstack-config --set /etc/neutron/dhcp_agent.ini DEFAULT debug false

12、重新配置/etc/nova/nova.conf，配置这步的目的是让compute节点能使用上neutron网络
# openstack-config --set /etc/nova/nova.conf neutron url http://controller:9696
# openstack-config --set /etc/nova/nova.conf neutron auth_url http://controller:35357
# openstack-config --set /etc/nova/nova.conf neutron auth_plugin password
# openstack-config --set /etc/nova/nova.conf neutron project_domain_id default
# openstack-config --set /etc/nova/nova.conf neutron user_domain_id default
# openstack-config --set /etc/nova/nova.conf neutron region_name RegionOne
# openstack-config --set /etc/nova/nova.conf neutron project_name service
# openstack-config --set /etc/nova/nova.conf neutron username neutron
# openstack-config --set /etc/nova/nova.conf neutron password devops
# openstack-config --set /etc/nova/nova.conf neutron service_metadata_proxy True
# openstack-config --set /etc/nova/nova.conf neutron metadata_proxy_shared_secret devops

13、将dhcp-option-force=26,1450写入/etc/neutron/dnsmasq-neutron.conf
# echo "dhcp-option-force=26,1450" >/etc/neutron/dnsmasq-neutron.conf

14、配置/etc/neutron/metadata_agent.ini
# openstack-config --set /etc/neutron/metadata_agent.ini DEFAULT nova_metadata_ip controller
# openstack-config --set /etc/neutron/metadata_agent.ini DEFAULT metadata_proxy_shared_secret devops
# openstack-config --set /etc/neutron/metadata_agent.ini DEFAULT metadata_workers 4
# openstack-config --set /etc/neutron/metadata_agent.ini DEFAULT verbose True
# openstack-config --set /etc/neutron/metadata_agent.ini DEFAULT debug false
# openstack-config --set /etc/neutron/metadata_agent.ini DEFAULT nova_metadata_protocol http

15、创建软链接
# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

16、同步数据库
# 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

17、重启nova服务，因为刚才改了nova.conf
# systemctl restart openstack-nova-api.service
# systemctl status openstack-nova-api.service

18、重启neutron服务并设置开机启动
# systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
# systemctl restart neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
# systemctl status neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service

19、启动neutron-l3-agent.service并设置开机启动
# systemctl enable neutron-l3-agent.service
# systemctl restart neutron-l3-agent.service
# systemctl status neutron-l3-agent.service

20、执行验证
# source /root/admin-openrc
# neutron ext-list
# neutron agent-list

21、创建vxLan模式网络，让虚拟机能外出
a. 首先先执行环境变量
# source /root/admin-openrc

b. 创建flat模式的public网络，注意这个public是外出网络，必须是flat模式的
# neutron --debug net-create --shared provider --router:external True --provider:network_type flat --provider:physical_network provider

执行完这步，在界面里进行操作，把public网络设置为共享和外部网络，创建后，结果为:

c. 创建public网络子网，名为public-sub，网段就是9.110.187，并且IP范围是50-90（这个一般是给VM用的floating IP了），dns设置为8.8.8.8，网关为9.110.187.2
# neutron subnet-create provider 9.110.187.0/24 --name provider-sub --allocation-pool start=9.110.187.50,end=9.110.187.90 --dns-nameserver 8.8.8.8 --gateway 9.110.187.2

d. 创建名为private的私有网络, 网络模式为vxlan
# neutron net-create private --provider:network_type vxlan --router:external False --shared

e. 创建名为private-subnet的私有网络子网，网段为192.168.1.0, 这个网段就是虚拟机获取的私有的IP地址
# neutron subnet-create private --name private-subnet --gateway 192.168.1.1 192.168.1.0/24

假如你们公司的私有云环境是用于不同的业务，比如行政、销售、技术等，那么你可以创建3个不同名称的私有网络
# neutron net-create private-office --provider:network_type vxlan --router:external False --shared
# neutron subnet-create private-office --name office-net --gateway 192.168.2.1 192.168.2.0/24

# neutron net-create private-sale --provider:network_type vxlan --router:external False --shared
# neutron subnet-create private-sale --name sale-net --gateway 192.168.3.1 192.168.3.0/24

# neutron net-create private-technology --provider:network_type vxlan --router:external False --shared
# neutron subnet-create private-technology --name technology-net --gateway 192.168.4.1 192.168.4.0/24

f. 创建路由，我们在界面上操作
点击项目-->网络-->路由-->新建路由

路由名称随便命名，我这里写"router", 管理员状态，选择"上"(up)，外部网络选择"provider"

点击"新建路由"后，提示创建router创建成功

接着点击"接口"-->"增加接口"

添加一个连接私网的接口，选中"private: 192.168.12.0/24"

点击"增加接口"成功后，我们可以看到两个接口先是down的状态，过一会儿刷新下就是running状态（注意，一定得是运行running状态，不然到时候虚拟机网络会出不去）

22、检查网络服务
# neutron agent-list
看服务是否是笑脸

八、安装Dashboard

1、安装dashboard相关软件包
# yum install openstack-dashboard -y

2、修改配置文件/etc/openstack-dashboard/local_settings
# vim /etc/openstack-dashboard/local_settings

直接覆盖我给的local_settings文件也行（为了减少出错，大家还是用我提供的local_settings文件替换覆盖）

3、启动dashboard服务并设置开机启动
# systemctl restart httpd.service memcached.service
# systemctl status httpd.service memcached.service

到此，Controller节点搭建完毕，打开firefox浏览器即可访问http://9.110.187.150/dashboard/ 可进入openstack界面！

九、安装配置cinder

1、创建数据库用户并赋予权限
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'devops';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'devops';

2、创建cinder用户并赋予admin权限
# source /root/admin-openrc
# openstack user create --domain default cinder --password devops
# openstack role add --project service --user cinder admin

3、创建volume服务
# openstack service create --name cinder --description "OpenStack Block Storage" volume
# openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2

4、创建endpoint
# openstack endpoint create --region RegionOne volume public http://controller:8776/v1/%\(tenant_id\)s
# openstack endpoint create --region RegionOne volume internal http://controller:8776/v1/%\(tenant_id\)s
# openstack endpoint create --region RegionOne volume admin http://controller:8776/v1/%\(tenant_id\)s
# openstack endpoint create --region RegionOne volumev2 public http://controller:8776/v2/%\(tenant_id\)s
# openstack endpoint create --region RegionOne volumev2 internal http://controller:8776/v2/%\(tenant_id\)s
# openstack endpoint create --region RegionOne volumev2 admin http://controller:8776/v2/%\(tenant_id\)s

5、安装cinder相关服务
# yum install openstack-cinder -y

6、配置cinder配置文件
# cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.bak
# >/etc/cinder/cinder.conf

# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken user_domain_name default
# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken project_name service
# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken username cinder
# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken password devops
# openstack-config --set /etc/cinder/cinder.conf oslo_concurrency lock_path /var/lib/cinder/tmp

7、上同步数据库
# su -s /bin/sh -c "cinder-manage db sync" cinder

8、在controller上启动cinder服务，并设置开机启动
# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
# systemctl restart openstack-cinder-api.service openstack-cinder-scheduler.service
# systemctl status openstack-cinder-api.service openstack-cinder-scheduler.service

9、安装Cinder节点，Cinder节点这里我们需要额外的添加一个硬盘（/dev/sdb)用作cinder的存储服务 (注意！这一步是在cinder节点操作的）
# yum install lvm2 -y

10、启动服务并设置为开机自启 (注意！这一步是在cinder节点操作的）
# systemctl enable lvm2-lvmetad.service
# systemctl start lvm2-lvmetad.service
# systemctl status lvm2-lvmetad.service

11、创建lvm, 这里的/dev/sdb就是额外添加的硬盘 (注意！这一步是在cinder节点操作的）
# fdisk -l
# pvcreate /dev/sdb
# vgcreate cinder-volumes /dev/sdb

12. 编辑存储节点lvm.conf文件 (注意！这一步是在cinder节点操作的）
# vim /etc/lvm/lvm.conf
在devices 下面添加 filter = [ "a/sda/", "a/sdb/", "r/.*/"] ，130行，如图：

然后重启下lvm2服务：
# systemctl restart lvm2-lvmetad.service
# systemctl status lvm2-lvmetad.service

13、安装openstack-cinder、targetcli (注意！这一步是在cinder节点操作的）
# yum install openstack-cinder openstack-utils targetcli python-keystone ntpdate -y

14、配置cinder配置文件 (注意！这一步是在cinder节点操作的）
# cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.bak

# openstack-config --set /etc/nova/nova.conf neutron project_domain_name default
# openstack-config --set /etc/nova/nova.conf neutron user_domain_name default
# openstack-config --set /etc/nova/nova.conf neutron region_name RegionOne
# openstack-config --set /etc/nova/nova.conf neutron project_name service
# openstack-config --set /etc/nova/nova.conf neutron username neutron
# openstack-config --set /etc/nova/nova.conf neutron password devops

5. 重启和enable相关服务
# systemctl restart libvirtd.service openstack-nova-compute.service
# systemctl enable neutron-linuxbridge-agent.service
# systemctl restart neutron-linuxbridge-agent.service
# systemctl status libvirtd.service openstack-nova-compute.service neutron-linuxbridge-agent.service

三、计算节点结合Cinder
1.计算节点要是想用cinder,那么需要配置nova配置文件 (注意！这一步是在计算节点操作的）
# openstack-config --set /etc/nova/nova.conf cinder os_region_name RegionOne
# systemctl restart openstack-nova-compute.service

2.然后在controller上重启nova服务
# systemctl restart openstack-nova-api.service
# systemctl status openstack-nova-api.service

四. 在controler上执行验证
# source /root/admin-openrc
# neutron agent-list
# nova-manage cell_v2 discover_hosts

到此，Compute节点搭建完毕，运行nova host-list可以查看新加入的compute1节点
如果需要再添加另外一个compute节点，只要重复下第二大部即可，记得把计算机名和IP地址改下。

附-创建配额命令

# openstack flavor create m1.tiny --id 1 --ram 512 --disk 1 --vcpus 1
# openstack flavor create m1.small --id 2 --ram 2048 --disk 20 --vcpus 1
# openstack flavor create m1.medium --id 3 --ram 4096 --disk 40 --vcpus 2
# openstack flavor create m1.large --id 4 --ram 8192 --disk 80 --vcpus 4
# openstack flavor create m1.xlarge --id 5 --ram 16384 --disk 160 --vcpus 8
# openstack flavor list
