完整部署CentOS7.2+OpenStack+kvm 云平台环境

1 OpenStack 介绍

1.1 百度百科
OpenStack 是一个由 NASA （美国国家航空航天局）和 Rackspace 合作研发并发起的，以 Apache
许可证授权的自由软件和开放源代码项目。

1.2 版本历史

1.3 openstack 架构概念

1.4 openstack 各个服务名称对应

***************************************************************************************************************

以下安装部署已经过测试，完全通过！

2 环境准备
openstack 主机名不能改，装的时候是什么就是什么，运维标准化。

1、 CentOS 7.2 系统 2 台
此处：
node1 即作为控制节点，也作为计算节点；【即可以单机部署，既是控制节点，也作为计算节点】
node2 就只是计算节点
控制节点去操控节点节点，计算节点上可以创建虚拟机

linux-node1.openstack 192.168.1.17 网卡 NAT em2 （外网ip假设是58.68.250.17）【em2是内网网卡，下面neutron配置文件里会设置到】
linux-node2.openstack 192.168.1.8 网卡 NAT em2

控制节点：linux-node1.openstack 192.168.1.17

计算节点：linux-node2.openstack 192.168.1.8

2.域名解析和关闭防火墙（控制节点和计算节点都做）
/etc/hosts
192.168.1.17linux-node1.openstack
192.168.1.8 linux-node2.openstack

关闭 selinux
sed -i.bak s#SELINUX=enforcing#SELINUX=disabled#g /etc/selinux/config
setenforce 0
关闭 iptables
systemctl start firewalld.service
systemctl stop firewalld.service
systemctl disable firewalld.service

参考另一篇博客：http://www.cnblogs.com/kevingrace/p/5811167.html
修改下MysqL的连接数，否则openstack后面的操作会报错：“ERROR 1040 (08004): Too many connections ”
--------------------------------------------------------------------------------------------------

3.4 配置 rabbitmq
MQ 全称为 Message Queue,消息队列（ MQ）是一种应用程序对应用程序的通信方法。应用
程序通过读写出入队列的消息（针对应用程序的数据）来通信，而无需专用连接来链接它们。
消息传递指的是程序之间通过在消息中发送数据进行通信，而不是通过直接调用彼此来通
信，直接调用通常是用于诸如远程过程调用的技术。排队指的是应用程序通过队列来通信。
队列的使用除去了接收和发送应用程序同时执行的要求。
RabbitMQ 是一个在 AMQP 基础上完整的，可复用的企业消息系统。他遵循 Mozilla Public
License 开源协议。
启动 rabbitmq，端口 5672，添加 openstack 用户

[root@linux-node1 ~]# systemctl enable rabbitmq-server.service
[root@linux-node1 ~]# ln -s '/usr/lib/systemd/system/rabbitmq-server.service' '/etc/systemd/system/multi-user.target.wants/rabbitmq-server.service'
[root@linux-node1 ~]# systemctl start rabbitmq-server.service
[root@linux-node1 ~]# rabbitmqctl add_user openstack openstack #添加用户及密码
[root@linux-node1 ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*" #允许配置、写、读访问 openstack
[root@linux-node1 ~]# rabbitmq-plugins list #查看支持的插件
.........
[ ] rabbitmq_management 3.6.2 #使用此插件实现 web 管理
.........
[root@linux-node1 ~]# rabbitmq-plugins enable rabbitmq_management #启动插件
The following plugins have been enabled:
mochiweb
webmachine
rabbitmq_web_dispatch
amqp_client
rabbitmq_management_agent
rabbitmq_management
Plugin configuration has changed. Restart RabbitMQ for changes to take effect.
[root@linux-node1 ~]# systemctl restart rabbitmq-server.service

[root@linux-node1 ~]#lsof -i:15672

访问RabbitMQ,访问地址是http://58.68.250.17:15672
默认用户名密码都是guest，浏览器添加openstack用户到组并登陆测试，连不上情况一般是防火墙没有关闭所致！

之后退出使用 openstack 登录
如何使用 zabbix 监控？
左下角有 HTTP API 的介绍，可以实现 zabbix 的监控

*********************************************************************************************

以上完成基础环境的配置，下面开始安装 openstack 的组件

3.5 配置 Keystone 验证服务
所有的服务，都需要在 keystone 上注册
3.5.1 Keystone 介绍

3.5.2 配置 Keystone
端口 5000 和 35357

1、修改/etc/keystone/keystone.conf
取一个随机数
[root@linux-node1 ~]# openssl rand -hex 10
35d6e6f377a889571bcf
[root@linux-node1 ~]# cat /etc/keystone/keystone.conf|grep -v "^#"|grep -v "^$"
[DEFAULT]
admin_token = 35d6e6f377a889571bcf #设置 token，和上面产生的随机数值一致
verbose = true
[assignment]
[auth]
[cache]
[catalog]
[cors]
[cors.subdomain]
[credential]
[database]
connection = MysqL://keystone:keystone@192.168.1.17/keystone #设置数据库连接写到database下
[domain_config]
[endpoint_filter]
[endpoint_policy]
[eventlet_server]
[eventlet_server_ssl]
[federation]
[fernet_tokens]
[identity]
[identity_mapping]
[kvs]
[ldap]
[matchmaker_redis]
[matchmaker_ring]
[memcache]
servers = 192.168.1.17:11211
[oauth1]
[os_inherit]
[oslo_messaging_amqp]
[oslo_messaging_qpid]
[oslo_messaging_rabbit]
[oslo_middleware]
[oslo_policy]
[paste_deploy]
[policy]
[resource]
[revoke]
driver = sql
[role]
[saml]
[signing]
[ssl]
[token]
provider = uuid
driver = memcache
[tokenless_auth]
[trust]

2、创建数据库表，使用命令同步
[root@linux-node1 ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone

No handlers could be found for logger "oslo_config.cfg" #出现这个信息，不影响后续操作！忽略~

[root@linux-node1 ~]# ll /var/log/keystone/keystone.log
-rw-r--r--. 1 keystone keystone 298370 Aug 26 11:36 /var/log/keystone/keystone.log ##之所以上面 su 切换是因为这个日志文件属主
[root@linux-node1 config]# MysqL -h 192.168.1.17 -u keystone -p #数据库检查表,生产环境密码不要用keystone，改成复杂点的密码

3、启动 memcached 和 apache
启动 memcached
[root@linux-node1 ~]# systemctl enable memcached
[root@linux-node1 ~]#ln -s '/usr/lib/systemd/system/memcached.service' '/etc/systemd/system/multi-user.target.wants/memcached.service'
[root@linux-node1 ~]# systemctl start memcached
配置 httpd
[root@linux-node1 ~]# vim /etc/httpd/conf/httpd.conf
ServerName 192.168.56.11:80
[root@linux-node1 ~]# 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}
WSGIProcessGroup keystone-public
WSGIScriptAlias / /usr/bin/keystone-wsgi-public
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
<IfVersion >= 2.4>
ErrorLogFormat "%{cu}t %M"
</IfVersion>
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>
Order allow,deny
Allow from all
</IfVersion>
</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
<IfVersion >= 2.4>
ErrorLogFormat "%{cu}t %M"
</IfVersion>
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>
Order allow,deny
Allow from all
</IfVersion>
</Directory>
</VirtualHost>

启动 httpd
[root@linux-node1 config]# systemctl enable httpd
[root@linux-node1 config]#ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'
[root@linux-node1 config]# systemctl start httpd
[root@linux-node1 ~]# netstat -lntup|grep httpd
tcp6 0 0 :::5000 :::* LISTEN 23632/httpd
tcp6 0 0 :::80 :::* LISTEN 23632/httpd
tcp6 0 0 :::35357 :::* LISTEN 23632/httpd
如果 http 起不来关闭 selinux 或者安装 yum install openstack-selinux

4、创建 keystone 用户
临时设置 admin_token 用户的环境变量，用来创建用户
[root@linux-node1 ~]# export OS_TOKEN=35d6e6f377a889571bcf #上面产生的随机数值
[root@linux-node1 ~]# export OS_URL=http://192.168.1.17:35357/v3
[root@linux-node1 ~]# export OS_IDENTITY_API_VERSION=3

创建 admin 项目---创建 admin 用户（密码 admin，生产不要这么玩） ---创建 admin 角色---把 admin 用户加入到 admin 项目赋予 admin 的角色（三个 admin 的位置：项目，用户，角色）
[root@linux-node1 ~]#openstack project create --domain default --description "Admin Project" admin
[root@linux-node1 ~]#openstack user create --domain default --password-prompt admin
[root@linux-node1 ~]#openstack role create admin
[root@linux-node1 ~]#openstack role add --project admin --user admin admin
创建一个普通用户 demo
[root@linux-node1 ~]#openstack project create --domain default --description "Demo Project" demo
[root@linux-node1 ~]#openstack user create --domain default --password=demo demo
[root@linux-node1 ~]#openstack role create user
[root@linux-node1 ~]#openstack role add --project demo --user demo user

创建 service 项目，用来管理其他服务用
[root@linux-node1 ~]#openstack project create --domain default --description "Service Project" service

以上的名字都是固定的，不能改

6、验证，获取 token，只有获取到才能说明 keystone 配置成功
[root@linux-node1 ~]# unset OS_TOKEN
[root@linux-node1 ~]# unset OS_URL
[root@linux-node1 ~]# openstack --os-auth-url http://192.168.1.17:35357/v3 --os-project-domain-id default --os-user-domain-id default --os-project-name admin --os-username admin --os-auth-type password token issue #回车
Password: admin
+------------+----------------------------------+
| Field | Value |
+------------+----------------------------------+
| expires | 2015-12-17T04:22:00.600668Z |
| id | 1b530a078b874438aadb77af11ce297e |
| project_id | 777f4f0108b1476eabc11e00dccaea9f |
| user_id | b694d8f0b70b41d883665f9524c77766 |
+------------+----------------------------------+

使用环境变量来获取 token，环境变量在后面创建虚拟机时也需要用。
创建两个环境变量文件，使用时直接 source！！！（注意，下面两个sh文件所在的路径，在查看命令前都要source下，不然会报错！！）
[root@linux-node1 ~]# cat admin-openrc.sh
export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_NAME=admin
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=admin
export OS_AUTH_URL=http://192.168.1.17:35357/v3
export OS_IDENTITY_API_VERSION=3

[root@linux-node1 ~]# cat demo-openrc.sh
export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_NAME=demo
export OS_TENANT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=demo
export OS_AUTH_URL=http://192.168.1.17:5000/v3
export OS_IDENTITY_API_VERSION=3
[root@linux-node1 ~]# source admin-openrc.sh
[root@linux-node1 ~]# openstack token issue
+------------+----------------------------------+
| Field | Value |
+------------+----------------------------------+
| expires | 2015-12-17T04:26:08.625399Z |
| id | 58370ae3b9bb4c07a67700dd184ad3b1 |

2、创建数据库表，同步数据库
[root@linux-node1 ~]# su -s /bin/sh -c "glance-manage db_sync" glance
[root@linux-node1 ~]# MysqL -h 192.168.1.17 -uglance -p

3、创建关于 glance 的 keystone 用户
[root@linux-node1 ~]# source admin-openrc.sh
[root@linux-node1 ~]# openstack user create --domain default --password=glance glance
[root@linux-node1 ~]# openstack role add --project service --user glance admin

4、启动 glance
[root@linux-node1 ~]#systemctl enable openstack-glance-api
[root@linux-node1 ~]#systemctl enable openstack-glance-registry
[root@linux-node1 ~]#systemctl start openstack-glance-api
[root@linux-node1 ~]#systemctl start openstack-glance-registry
[root@linux-node1 ~]# netstat -lnutp |grep 9191 #registry

实际生产环境下，肯定要使用ios镜像进行制作了

http://www.cnblogs.com/kevingrace/p/5821823.html

************************************************************************************

或者直接下载centos的qcow2格式镜像进行上传，qcow2格式镜像直接就可以在openstack里使用，不需要进行格式转换！
下载地址：http://cloud.centos.org/centos，可以到里面下载centos5/6/7的qcow2格式的镜像

[root@linux-node1 ~]#wget http://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud.qcow2
[root@linux-node1 ~]#glance image-create --name "CentOS-7-x86_64" --file CentOS-7-x86_64-GenericCloud.qcow2 --disk-format qcow2 --container-format bare --visibility public --progress

3.8 Neutron 网络服务
3.8.1 Neutron 介绍
neutron 由来

openstack 网络分类：

Neutron 组件

3.8.2Neutron 控制节点配置（ 5 个配置文件）
1、修改/etc/neutron/neutron.conf文件

[root@linux-node1 ~]# cat /etc/neutron/neutron.conf|grep -v "^#"|grep -v "^$"
[DEFAULT]
state_path = /var/lib/neutron
core_plugin = ml2

rpc_backend=rabbit
[matchmaker_redis]
[matchmaker_ring]
[quotas]
[agent]
[keystone_authtoken]
auth_uri = http://192.168.1.17:5000

admin_tenant_name = %SERVICE_TENANT_NAME%
admin_user = %SERVICE_USER%
admin_password = %SERVICE_PASSWORD%
[database]
connection = MysqL://neutron:neutron@192.168.1.17:3306/neutron
[nova]
auth_url = http://192.168.1.17:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
region_name = RegionOne
project_name = service
username = nova
password = nova
[oslo_concurrency]
lock_path = $state_path/lock
[oslo_policy]
[oslo_messaging_amqp]
[oslo_messaging_qpid]
[oslo_messaging_rabbit]
rabbit_host = 192.168.1.17
rabbit_port = 5672
rabbit_userid = openstack
rabbit_password = openstack
[qos]

2、配置/etc/neutron/plugins/ml2/ml2_conf.ini
[root@linux-node1 ~]# cat /etc/neutron/plugins/ml2/ml2_conf.ini|grep -v "^#"|grep -v "^$"
[ml2]
type_drivers = flat,vlan,gre,vxlan,geneve
tenant_network_types = vlan,geneve
mechanism_drivers = openvswitch,linuxbridge
extension_drivers = port_security
[ml2_type_flat]
flat_networks = physnet1
[ml2_type_vlan]
[ml2_type_gre]
[ml2_type_vxlan]
[ml2_type_geneve]
[securitygroup]
enable_ipset = True

3、配置/etc/neutron/plugins/ml2/ linuxbridge_agent.ini
[root@linux-node1 ~]# cat /etc/neutron/plugins/ml2/linuxbridge_agent.ini|grep -v "^#"|grep -v "^$"
[linux_bridge]
physical_interface_mappings = physnet1:em2
[vxlan]
enable_vxlan = false
[agent]
prevent_arp_spoofing = True
[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
enable_security_group = True

4、修改/etc/neutron/dhcp_agent.ini
[root@linux-node1 ~]# cat /etc/neutron/dhcp_agent.ini|grep -v "^#"|grep -v "^$"
[DEFAULT]
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_Metadata = true
[AGENT]

5、修改/etc/neutron/Metadata_agent.ini
[root@linux-node1 ~]# cat /etc/neutron/Metadata_agent.ini|grep -v "^#"|grep -v "^$"
[DEFAULT]
auth_uri = http://192.168.1.17:5000
auth_url = http://192.168.1.17:35357
auth_region = RegionOne
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = neutron
password = neutron
nova_Metadata_ip = 192.168.1.17
Metadata_proxy_shared_secret = neutron
admin_tenant_name = %SERVICE_TENANT_NAME%
admin_user = %SERVICE_USER%
admin_password = %SERVICE_PASSWORD%
[AGENT]

6、创建连接并创建 keystone 的用户
[root@linux-node1 ~]# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
[root@linux-node1 ~]# openstack user create --domain default --password=neutron neutron
[root@linux-node1 ~]# openstack role add --project service --user neutron admin

7、更新数据库
[root@linux-node1 ~]# 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

8、注册 keystone
[root@linux-node1 ~]# source admin-openrc.sh
[root@linux-node1 ~]# openstack service create --name neutron --description "OpenStack Networking" network
[root@linux-node1 ~]# openstack endpoint create --region RegionOne network public http://192.168.1.17:9696
[root@linux-node1 ~]# openstack endpoint create --region RegionOne network internal http://192.168.1.17:9696
[root@linux-node1 ~]# openstack endpoint create --region RegionOne network admin http://192.168.1.17:9696

9、启动服务并检查
因为 neutron 和 nova 有联系，做 neutron 时修改 nova 的配置文件，所以要重启
openstack-nova-api 服务，此处不用，因为上面的 nova 已经设置
[root@linux-node1 ~]# systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-Metadata-agent.service
[root@linux-node1 ~]# systemctl start neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-Metadata-agent.service

3.8.3Neutron 计算节点配置
1、修改相关配置文件
从 node1 上直接拷贝

[root@linux-node1~]# scp /etc/neutron/neutron.conf 192.168.1.8:/etc/neutron/
[root@linux-node1 ~]# scp /etc/neutron/plugins/ml2/linuxbridge_agent.ini 192.168.1.8:/etc/neutron/plugins/ml2/
[root@linux-node1 ~]# scp /etc/neutron/plugins/ml2/ml2_conf.ini 192.168.1.8:/etc/neutron/plugins/ml2/
修改计算节点的 nova 配置文件中 neutron 部分，并重启 openstack-nova-compute 服务，因为
上面 nova 计算节点也是从控制节点拷贝的，此处无需操作

2、创建软连接并启动服务
[root@linux-node2~]# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
[root@linux-node2~]# systemctl enable neutron-linuxbridge-agent.service
[root@linux-node2~]# systemctl start neutron-linuxbridge-agent.service

3.9 创建虚拟机
3.9.1 创建桥接网络

1、创建网络
[root@linux-node1 ~]# source admin-openrc.sh #在哪个项目下创建虚拟机，这里选择在demo下创建；也可以在admin下
[root@linux-node1 ~]# neutron net-create flat --shared --provider:physical_network physnet1 --provider:network_type flat

2、创建子网（填写宿主机的内网网关）
[root@linux-node1 ~]# neutron subnet-create flat 192.168.1.0/24 --name flat-subnet --allocation-pool start=192.168.1.100,end=192.168.1.200 --dns-nameserver 192.168.1.1--gateway 192.168.1.1

3、查看子网
[root@linux-node1 ~]# neutron net-list
+--------------------------------------+------+-----------------------------------------------------+
| id | name | subnets |
+--------------------------------------+------+-----------------------------------------------------+
| 1d9657f6-de9e-488f-911f-020c8622fe78 | flat | c53da14a-01fe-4f6c-8485-232489deaa6e 192.168.1.0/24 |
+--------------------------------------+------+-----------------------------------------------------+

[root@linux-node1 ~]# neutron subnet-list
+--------------------------------------+-------------+----------------+----------------------------------------------------+
| id | name | cidr | allocation_pools |
+--------------------------------------+-------------+----------------+----------------------------------------------------+
| c53da14a-01fe-4f6c-8485-232489deaa6e | flat-subnet | 192.168.1.0/24 | {"start": "192.168.1.100","end": "192.168.1.200"} |
+--------------------------------------+-------------+----------------+----------------------------------------------------+
需要关闭 VMware 的 dhcp

3.9.2 创建虚拟机
1、创建 key
[root@linux-node1 ~]# source demo-openrc.sh
[root@linux-node1 ~]# ssh-keygen -q -N ""

2、将公钥添加到虚拟机
[root@linux-node1 ~]# nova keypair-add --pub-key .ssh/id_rsa.pub mykey
[root@linux-node1 ~]# nova keypair-list
+-------+-------------------------------------------------+
| Name | Fingerprint |
+-------+-------------------------------------------------+
| mykey | cd:7a:1e:cd:c0:43:9b:b1:f4:3b:cf:cd:5e:95:f8:00 |
+-------+-------------------------------------------------+

3、创建安全组
[root@linux-node1 ~]# nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
[root@linux-node1 ~]# nova secgroup-add-rule default tcp 22 22 0.0.0.0/0

4、创建虚拟机
查看支持的虚拟机类型
[root@linux-node1 ~]# nova flavor-list
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| ID | Name | Memory_MB | Disk | Ephemeral | Swap | Vcpus | RXTX_Factor | Is_Public |
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| 1 |m1.tiny| 512 | 1 | 0 | | 1 | 1.0 | True |
| 2 | m1.small | 2048 | 20 | 0 | | 1 | 1.0 | True |
| 3 | m1.medium | 4096 | 40 | 0 | | 2 | 1.0 | True |
| 4 | m1.large | 8192 | 80 | 0 | | 4 | 1.0 | True |
| 5 | m1.xlarge | 16384 | 160 | 0 | | 8 | 1.0 | True |
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
查看镜像
[root@linux-node1 ~]# nova image-list
+--------------------------------------+--------+--------+--------+
| ID | Name | Status | Server |
+--------------------------------------+--------+--------+--------+
| 2707a30b-853f-4d04-861d-e05b0f1855c8 | cirros | ACTIVE | |
+--------------------------------------+--------+--------+--------+
查看网络
[root@linux-node1 ~]# neutron net-list
+--------------------------------------+------+-----------------------------------------------------+
| id | name | subnets |
+--------------------------------------+------+-----------------------------------------------------+
|1d9657f6-de9e-488f-911f-020c8622fe78| flat | c53da14a-01fe-4f6c-8485-232489deaa6e 192.168.1.0/24 |
+--------------------------------------+------+-----------------------------------------------------+

创建虚拟机【这一步容易报错，一般都是由于上面的 nova.conf 配置填写有误所致】
[root@linux-node1 ~]# nova boot --flavorm1.tiny--imagecirros--nic net-id=1d9657f6-de9e-488f-911f-020c8622fe78--security-group default --key-namemykeyhello-instance

5、查看虚拟机

*************************************************************************
如果要删除虚拟机（利用虚拟机ID进行删除）
[root@linux-node1 ~]# nova delete 7a6215ac-aea7-4e87-99a3-b62c06d4610e
*************************************************************************

[root@linux-node1 ~]# ssh cirros@192.168.1.101 登录查看

******************************************************************************

上面创建虚拟机的时候，openstack在neutron组网内是采用dhcp-agent自动分配ip的！

可以在创建虚拟机的时候，指定固定ip，方法详见于另一篇博客：

http://www.cnblogs.com/kevingrace/p/5822660.html

******************************************************************************

6、 web 界面打开虚拟机
[root@linux-node1 ~]# nova get-vnc-console hello-instance novnc
+-------+-----------------------------------------------------------------------------------
-+
| Type | Url
| +
-------+-----------------------------------------------------------------------------------
-+
| novnc |http://58.68.250.17:6080/vnc_auto.html?token=303d5a78-c85f-4ed9-93b6-be9d5d28fba6| #访问这个链接即可打开vnc界面
+-------+-----------------------------------------------------------------------------------
-+

4.0 安装 dashboard，登陆 web 管理界面
[root@linux-node1 ~]# yum install openstack-dashboard -y
[root@linux-node1 ~]# vim /etc/openstack-dashboard/local_settings 按照下面几行进行配置修改
OPENSTACK_HOST = "192.168.1.17" #更改为keystone机器地址
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user" #默认的角色
ALLOWED_HOSTS = ['*'] #允许所有主机访问
CACHES = {
'default': {
'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
'LOCATION': '192.168.1.17:11211',#连接memcached
}
}
#CACHES = {
# 'default': {
# 'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
# }
#}
TIME_ZONE = "Asia/Shanghai" #设置时区

重启 httpd 服务
[root@linux-node1 ~]# systemctl restart httpd

web 界面登录访问dashboard
http://58.68.250.17/dashboard/
用户密码 demo 或者 admin（管理员）

---------------------------------------------------------------------------------------------
如果要修改dashboard的访问端口（比如将80端口改为8080端口），则需要修改下面两个配置文件：
1）vim /etc/httpd/conf/httpd.conf
将80端口修改为8080端口

Listen 8080
ServerName 192.168.1.8:8080

2）vim /etc/openstack-dashboard/local_settings #将下面两处的端口由80改为8080
'from_port': '8080',
'to_port': '8080',

然后重启http服务：
systemctl restart httpd

如果开启了防火墙，还需要开通8080端口访问规则

这样，dashboard访问url：
http://58.68.250.17:8080/dashboard
---------------------------------------------------------------------------------------------

前面建立了两个账号：admin 和 demo，两个账号都可以登陆web！只不过， admin 是管理员账号， admin 登陆后可以看到其他账号下的状态
demo 等普通账号登陆后只能看到自己的状态
注意：
上面的 Rabbit 账号 admin 和 openstack 是消息队列的 web 登陆账号。
比如一下子要建立 10 个虚拟机的指令，但是当前资源处理不过来，就通过 Rabbit 进行排队！！

*******************************************************************************************
修改OpenStack中dashboard用户登陆密码的方法：

登陆dashboard：

****************************************************************************************************

创建虚拟机的时候，我们可以自己定义虚拟机的类型（即配置）。

登陆openstack的web管理界面里进行自定义，也可以将之前的删除。

查看上传到glance的镜像

查看创建的虚拟机实例

自定义虚拟主机类型，设置如下：

（如果想让虚拟机有空闲磁盘空间，用于新建分区之用，则可以在这里分配临时磁盘）

我创建了四个虚拟机实例，采用的是同一个虚拟主机类型（即上面的kvm002），四个实例总共占用宿主机40G的空间。

登陆到openstack，可以看到，左侧一共有四个标签栏：

*****************************************************************************

可以在openstack界面里，在“计算-网络-网络拓扑”里选择“启动虚拟机”就可以再创建一个虚拟机

也可以按照快照再启动（创建）一个虚拟机，不过这样启动起来的虚拟机是一个新的ip（快照前的源虚拟机就要关机了）

查看实例，发现kvm-server005虚拟机已经创建成功了。默认创建后的ip是dhcp自动分配的，可以登陆虚拟机改成static静态ip

*****************************************************************************

在openstack 中重启实例有两种，分别被称为“软重启”和“硬重启”。所谓的软重启会尝试正常关机并重启实例，硬重启会直接将实例“断电”并重启。也就是说硬重启会“关闭”电源。其具体命令如下：
默认情况下，如果您通过nova重启，执行的是软重启。
$ nova reboot SERVER
如果您需要执行硬重启，添加--hard参数即可：
$ nova reboot --hard SERVER

nova命令管理虚拟机：

$ nova list #查看虚拟机
$ nova stop [vm-name]或[vm-id] #关闭虚拟机
$ nova start [vm-name]或[vm-id] #启动虚拟机
$ nova suspend [vm-name]或[vm-id] #暂停虚拟机
$ nova resume [vm-name]或[vm-id] #启动暂停的虚拟机
$ nova delete [vm-name]或[vm-id] #删除虚拟机

$nova-manage service list #检查服务是否正常

完整创建一个虚拟机的流程
[root@openstack ~]#nova keypair-add oskey > oskey.priv
[root@openstack ~]#chmod 600 oskey.priv
[root@openstack ~]#nova flavor-list
[root@openstack ~]#nova image-list
[root@openstack ~]#nova boot --flavor 2 --key_name oskey --image ea3ffba1-065e-483f-bfe2-c84184ee76be test1
[root@openstack ~]#nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
[root@openstack ~]#nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0

查看申请flating IP 列表
[root@openstack ~]#nova floating-ip-list

查看虚拟机
[root@openstack ~]#nova list

添加floating IP给虚拟机（id是虚拟机的ID，通过nova list获得）
[root@openstack ~]#nova add-floating-ip 7eb1d4b3-13fa-4e39-be17-3a27eb0db218 10.1.199.33

查看虚拟机的floating IP （nova list，就可以查看，需要等待1分钟）
[root@openstack ~]#nova list

ssh到虚拟机上（ubuntu的虚拟机，默认的用户名是ubuntu，只能用密钥登陆）
[root@openstack ~]#ssh -i oskey.priv ubuntu@192.168.22.2

删除flating IP （ID就是虚拟机ID，通过 nova list 获得）
[root@openstack ~]#nova remove-floating-ip ID 10.1.199.33

删除虚拟机
[root@openstack ~]#nova delete ID

创建10G的volume
[root@openstack ~]#nova volume-create --display_name "test volume" 10

查看nova volume情况
[root@openstack ~]#nova volume-list

把volume添加到虚拟机上
( ID是虚拟机的id，后面的1，是volume的ID）添加完后可以通过 nova volume-list查看结果
[root@openstack ~]#nova volume-attach 7eb1d4b3-13fa-4e39-be17-3a27eb0db218 1 /dev/vdc

查看虚拟机里的volume情况（登陆虚拟机里）
[root@openstack ~]# cat /proc/partitions
major minor #blocks name

253 0 10485760 vda
253 1 10474380 vda1
253 16 20971520 vdb
253 32 10485760 vdc

格式化分区
[root@openstack ~]#mkfs.ext4 /dev/vdc

[root@openstack ~]#mkdir -p /mnt/volume
[root@openstack ~]#mount /dev/vdc /mnt/volume

删除volume
[root@openstack ~]#nova volume-detach VM_ID Volume_ID

创建snapshot ( 完成后可以通过 nova image-list 查看）
[root@openstack ~]#nova image-create 7eb1d4b3-13fa-4e39-be17-3a27eb0db218 "snapshot 1"

虚拟机重启，停止
[root@openstack ~]#nova suspend ac9e6a9f-58c3-47c3-9b4c-485aa421b8a8
[root@openstack ~]#nova resume ac9e6a9f-58c3-47c3-9b4c-485aa421b8a8
[root@openstack ~]#nova reboot ac9e6a9f-58c3-47c3-9b4c-485aa421b8a8

vnc [root@openstack ~]#nova get-vnc-console myserver20 novnc
