本文主要分享的是雲計算、openstack的使用、私有云平臺建設、雲服務器雲硬盤的構建和使用。從基本概念入手到私有云建設,信息量很是大。對於openstack的安裝部署都是從官方文檔中一步步的介紹,內容很是詳細。html
1、雲計算 基本概念node
雲計算(cloud computing)是基於互聯網的相關服務的增長、使用和交付模式,一般涉及經過互聯網來提供動態易擴展且常常是虛擬化的資源。雲是網絡、互聯網的一種比喻說法。過去在圖中每每用雲來表示電信網,後來也用來表示互聯網和底層基礎設施的抽象。所以,雲計算甚至可讓你體驗每秒10萬億次的運算能力,擁有這麼強大的計算能力能夠模擬核爆炸、預測氣候變化和市場發展趨勢。用戶經過電腦、筆記本、手機等方式接入數據中心,按本身的需求進行運算。python
雲計算分類mysql
簡單來講,就是把應用程序和數據都放在由大量服務器組成的雲中,用戶須要什麼只要購買相應服務並使用便可。linux
雲計算分爲私有云、公有云、混合雲。web
雲計算的服務分類:基礎設施即服務、平臺即服務、軟件即服務。sql
2、Openstack基本概念數據庫
OpenStack是一個開源的雲計算管理平臺項目,由幾個主要的組件組合起來完成django
具體工做。OpenStack支持幾乎全部類型的雲環境,項目目標是提供實施簡單、centos
可大規模擴展、豐富、標準統一的雲計算管理平臺。OpenStack經過各類互補的
服務提供了基礎設施即服務(IaaS)的解決方案,每一個服務提供API以進行集成。
常見組件:
基礎的系統圖
Openstack安裝部署
下面來講一說openstack的安裝部署。首先說明openstack的總體安裝很是複雜,文末提供官方安裝文檔下載,我就是根據這個英文的官方文檔來安裝部署的。如下內容是參照官方文檔「openstack-install-guide-yum-icehouse.pdf」來的。
首先須要準備3臺linux的機器。我這裏選用的是centos6.6的64位的系統。配置IP地址,關閉防火牆,修改主機名。
• Controller Node: 1 processor, 2 GB memory, and 5 GB storage
• Compute01: 1 processor, 512 MB memory, and 5 GB storage
• Compute02 Node: 1 processor, 2 GB memory, and 10 GB storage
我這裏controller的ip地址是:192.168.44.147
computer01:192.168.44.148
computer02:192.168.44.149
基本環境配置
如下內容是在controller機器上配置的。
一、數據庫安裝。
由於須要一個數據庫,因此這裏選用了mysql數據庫。
yum install mysql mysql-server MySQL-python
編輯/etc/my.cnf文件,在裏面添加以下內容,主要意思就是設置編碼爲utf-8。
default-storage-engine = innodb innodb_file_per_table collation-server = utf8_general_ci init-connect = 'SET NAMES utf8' character-set-server = utf8
而後啓動服務,開機啓動。
# service mysqld start # chkconfig mysqld on # mysql_install_db # mysql_secure_installation
賦權,使其能夠遠程登陸。
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'a';
二、openstack基本包安裝。
# yum install yum-plugin-priorities # yum install http://repos.fedorapeople.org/repos/openstack/openstackicehouse/rdo-release-icehouse-3.noarch.rpm # yum install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8. noarch.rpm # yum install openstack-utils # yum install openstack-selinux
三、安裝消息隊列
yum install qpid-cpp-server
啓動服務
service qpidd start chkconfig qpidd on
權限認證服務(keystone)
安裝權限認證服務:
yum install openstack-keystone python-keystoneclient -y
建立用戶,寫入到配置文件中:
openstack-config --set /etc/keystone/keystone.conf \ database connection mysql://keystone:KEYSTONE_DBPASS@controller/keystone
建立keystone數據庫表:
$ mysql -u root -p mysql> CREATE DATABASE keystone; mysql> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \ IDENTIFIED BY 'KEYSTONE_DBPASS'; mysql> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \ IDENTIFIED BY 'KEYSTONE_DBPASS'; mysql> exit
自動生成表:
su -s /bin/sh -c "keystone-manage db_sync" keystone
設置用戶環境變量:
ADMIN_TOKEN=$(openssl rand -hex 10) echo $ADMIN_TOKEN openstack-config --set /etc/keystone/keystone.conf DEFAULT \ admin_token $ADMIN_TOKEN # keystone-manage pki_setup --keystone-user keystone --keystone-group keystone # chown -R keystone:keystone /etc/keystone/ssl # chmod -R o-rwx /etc/keystone/ssl
啓動keystone服務:
service openstack-keystone start chkconfig openstack-keystone on
將admin_token設置到環境變量中去。
export OS_SERVICE_TOKEN=$ADMIN_TOKEN export OS_SERVICE_ENDPOINT=http://controller:35357/v2.0
建立管理員用戶,默認的用戶名爲admin,密碼爲ADMIN_PASS,你能夠自定義修改:
[root@controller keystone]# keystone user-create --name=admin --pass=ADMIN_PASS --email=ADMIN_EMAIL +----------+----------------------------------+ | Property | Value | +----------+----------------------------------+ | email | ADMIN_EMAIL| | enabled | True | |id| 332f5ecb18c64bf687b154facd629fb6 | | name | admin | | username | admin | +----------+----------------------------------+ [root@controller keystone]# keystone role-create --name=admin +----------+----------------------------------+ | Property | Value | +----------+----------------------------------+ |id| ab5da2c50d7443efb0514e84c2b4adb7 | | name | admin | +----------+----------------------------------+ [root@controller keystone]# keystone tenant-create --name=admin --description="Admin Tenant" +-------------+----------------------------------+ | Property | Value | +-------------+----------------------------------+ | description | Admin Tenant | | enabled | True | | id | b89723a38b154eeea6416a83b293b0ad | | name| admin | +-------------+----------------------------------+ [root@controller keystone]# keystone user-role-add --user=admin --tenant=admin --role=admin [root@controller keystone]# keystone user-role-add --user=admin --role=_member_ --tenant=admin [root@controller keystone]#
建立一個權限認證服務,由於我這裏的主機名是controller,因此下面有 http://controller:35357/v2.0 這些信息,能夠自定義修改:
[root@controller keystone]# keystone service-create --name=keystone --type=identity \ > --description="OpenStack Identity" +-------------+----------------------------------+ | Property | Value | +-------------+----------------------------------+ | description |OpenStack Identity| | enabled | True | | id | 4bfd5f39b86c45edb92d5c0488987dd8 | | name| keystone | | type| identity | +-------------+----------------------------------+ [root@controller keystone]# keystone endpoint-create \ > --service-id=$(keystone service-list | awk '/ identity / {print $2}') \ > --publicurl=http://controller:5000/v2.0 \ > --internalurl=http://controller:5000/v2.0 \ > --adminurl=http://controller:35357/v2.0 +-------------+----------------------------------+ | Property | Value | +-------------+----------------------------------+ | adminurl | http://controller:35357/v2.0 | | id | 0350b72901a141498fe48304b13a1b98 | | internalurl | http://controller:5000/v2.0| | publicurl | http://controller:5000/v2.0| |region |regionOne | | service_id | 4bfd5f39b86c45edb92d5c0488987dd8 | +-------------+----------------------------------+ [root@controller keystone]# keystone user-create --name=demo --pass=DEMO_PASS --email=DEMO_EMAIL +----------+----------------------------------+ | Property | Value | +----------+----------------------------------+ | email |DEMO_EMAIL| | enabled | True | |id| b44a9a1462d74f4e928b3b339289a2ae | | name | demo | | username | demo | +----------+----------------------------------+ [root@controller keystone]# keystone tenant-create --name=demo --description="Demo Tenant" +-------------+----------------------------------+ | Property | Value | +-------------+----------------------------------+ | description | Demo Tenant| | enabled | True | | id | 7bd79509ee184a2098ca0644679b60a8 | | name| demo | +-------------+----------------------------------+ [root@controller keystone]# keystone user-role-add --user=demo --role=_member_ --tenant=demo [root@controller keystone]#
爲了方便咱們取到token,咱們能夠vi admin-openrc.sh,而後添加以下內容:
export OS_USERNAME=admin export OS_PASSWORD=ADMIN_PASS export OS_TENANT_NAME=admin export OS_AUTH_URL=http://controller:35357/v2.0
在每次關機重啓以後都要從新執行下面的命令,讓環境變量起做用。不然會報」Expecting an auth URL via either –os-auth-url or env[OS_AUTH_URL]」的錯誤:
source admin-openrc.sh
咱們可使用下面的命令查看keystone目前的用戶有哪些:
keystone user-list
測試效果:
打開restclient-ui-3.5-jar-with-dependencies.jar來測試效果:
url地址是: http://192.168.44.147:5000/v2.0/
訪問成功。
配置鏡像服務(glance)
在controller服務器中安裝服務:
yum install openstack-glance python-glanceclient openstack-config --set /etc/glance/glance-api.conf database \ connection mysql://glance:GLANCE_DBPASS@controller/glance openstack-config --set /etc/glance/glance-registry.conf database \ connection mysql://glance:GLANCE_DBPASS@controller/glance
在mysql數據庫中建立glance數據庫:
$ mysql -u root -p mysql> CREATE DATABASE glance; mysql> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \ IDENTIFIED BY 'GLANCE_DBPASS'; mysql> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \ IDENTIFIED BY 'GLANCE_DBPASS'; flush privileges;
自動生成表:
su -s /bin/sh -c "glance-manage db_sync" glance
在keystone上建立用戶:
keystone user-create --name=glance --pass=GLANCE_PASS --email=glance@example.com $ keystone user-role-add --user=glance --tenant=service --role=admin
配置受權服務:
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken \ auth_uri http://controller:5000 openstack-config --set /etc/glance/glance-api.conf keystone_authtoken \ auth_host controller openstack-config --set /etc/glance/glance-api.conf keystone_authtoken \ auth_port 35357 openstack-config --set /etc/glance/glance-api.conf keystone_authtoken \ auth_protocol http openstack-config --set /etc/glance/glance-api.conf keystone_authtoken \ admin_tenant_name service openstack-config --set /etc/glance/glance-api.conf keystone_authtoken \ admin_user glance openstack-config --set /etc/glance/glance-api.conf keystone_authtoken \ admin_password GLANCE_PASS openstack-config --set /etc/glance/glance-api.conf paste_deploy \ flavor keystone openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken \ auth_uri http://controller:5000 openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken \ auth_host controller openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken \ auth_port 35357 openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken \ auth_protocol http openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken \ admin_tenant_name service openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken \ admin_user glance openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken \ admin_password GLANCE_PASS openstack-config --set /etc/glance/glance-registry.conf paste_deploy \ flavor keystone
啓動服務:
service openstack-glance-api start # service openstack-glance-registry start # chkconfig openstack-glance-api on # chkconfig openstack-glance-registry on
建立服務:
$ keystone service-create --name=glance --type=image \ --description="OpenStack Image Service" $ keystone endpoint-create \ --service-id=$(keystone service-list | awk '/ image / {print $2}') \ --publicurl=http://controller:9292 \ --internalurl=http://controller:9292 \ --adminurl=http://controller:9292 [root@controller ~]# keystone service-create --name=glance --type=image \ > --description="OpenStack Image Service" /usr/lib64/python2.6/site-packages/Crypto/Util/number.py:57: PowmInsecureWarning: Not using mpz_powm_sec.

建立鏡像,先將下載好的cirros-0.3.2-x86_64-disk.img放置在/root目錄下,而後執行下面的命令:
複製代碼 代碼以下:
glance image-create --name "cirros-0.3.2-x86_64" --disk-format qcow2 \
--container-format bare --is-public True --progress < cirros-0.3.2-x86_64-disk.img
查看鏡像列表:
glance image-list
在前面咱們已經對kvm虛擬化有所瞭解,因此咱們如今知道qcow2就是一個鏡像文件。
服務器管理(Nova)
對於虛擬機管理咱們須要從controller和computer01進行配置。
先來看controller的配置:
yum install openstack-nova-api openstack-nova-cert openstack-nova-conductor \ openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler \ python-novaclient $ mysql -u root -p mysql> CREATE DATABASE nova; mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \ IDENTIFIED BY 'NOVA_DBPASS'; mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \ IDENTIFIED BY 'NOVA_DBPASS'; openstack-config --set /etc/nova/nova.conf database connection mysql://nova:NOVA_DBPASS@controller/nova openstack-config --set /etc/nova/nova.conf DEFAULT rpc_backend qpid openstack-config --set /etc/nova/nova.conf DEFAULT qpid_hostname controller openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 192.168.44.147 openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_listen 192.168.216.210 openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_proxyclient_address 192.168.44.147 openstack-config --set /etc/nova/nova.conf DEFAULT auth_strategy keystone openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_uri http://controller:5000 openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_host controller openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_protocol http openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_port 35357 openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_user nova openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_tenant_name service openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_password NOVA_PASS $ keystone user-create --name=nova --pass=NOVA_PASS --email=nova@example.com $ keystone user-role-add --user=nova --tenant=service --role=admin $ keystone service-create --name=nova --type=compute \ --description="OpenStack Compute" $ keystone endpoint-create \ --service-id=$(keystone service-list | awk '/ compute / {print $2}') \ --publicurl=http://controller:8774/v2/%\(tenant_id\)s \ --internalurl=http://controller:8774/v2/%\(tenant_id\)s \ --adminurl=http://controller:8774/v2/%\(tenant_id\)s
而後是computer01的配置:
yum install openstack-nova-compute openstack-config --set /etc/nova/nova.conf database connection mysql://nova:NOVA_DBPASS@controller/nova openstack-config --set /etc/nova/nova.conf DEFAULT auth_strategy keystone openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_uri http://controller:5000 openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_host controller openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_protocol http openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_port 35357 openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_user nova openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_tenant_name service openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_password NOVA_PASS openstack-config --set /etc/nova/nova.conf DEFAULT rpc_backend qpid openstack-config --set /etc/nova/nova.conf DEFAULT qpid_hostname controller openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 192.168.44.148 openstack-config --set /etc/nova/nova.conf DEFAULT vnc_enabled True openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_listen 0.0.0.0 openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_proxyclient_address 192.168.44.148 openstack-config --set /etc/nova/nova.conf DEFAULT novncproxy_base_url http://controller:6080/vnc_auto.html openstack-config --set /etc/nova/nova.conf DEFAULT glance_host controller openstack-config --set /etc/nova/nova.conf libvirt virt_type kvm
啓動服務:
service libvirtd start service messagebus start service openstack-nova-compute start chkconfig libvirtd on chkconfig messagebus on chkconfig openstack-nova-compute on
網絡服務配置
在controller端:
openstack-config --set /etc/nova/nova.conf DEFAULT \ network_api_class nova.network.api.API openstack-config --set /etc/nova/nova.conf DEFAULT \ security_group_api nova
在computer01端:
yum install openstack-nova-network openstack-nova-api # openstack-config --set /etc/nova/nova.conf DEFAULT \ network_api_class nova.network.api.API # openstack-config --set /etc/nova/nova.conf DEFAULT \ security_group_api nova # openstack-config --set /etc/nova/nova.conf DEFAULT \ network_manager nova.network.manager.FlatDHCPManager # openstack-config --set /etc/nova/nova.conf DEFAULT \ firewall_driver nova.virt.libvirt.firewall.IptablesFirewallDriver # openstack-config --set /etc/nova/nova.conf DEFAULT \ network_size 254 # openstack-config --set /etc/nova/nova.conf DEFAULT \ allow_same_net_traffic False # openstack-config --set /etc/nova/nova.conf DEFAULT \ multi_host True # openstack-config --set /etc/nova/nova.conf DEFAULT \ send_arp_for_ha True # openstack-config --set /etc/nova/nova.conf DEFAULT \ share_dhcp_address True # openstack-config --set /etc/nova/nova.conf DEFAULT \ force_dhcp_release True # openstack-config --set /etc/nova/nova.conf DEFAULT \ flat_network_bridge br100 # openstack-config --set /etc/nova/nova.conf DEFAULT \ flat_interface eth1 # openstack-config --set /etc/nova/nova.conf DEFAULT \ public_interface eth0
nova network-create demo-net –bridge br100 –multi-host T \
–fixed-range-v4 88.8.8.16/28
而後使用nova net-list來查看:
建立虛擬機
一、配置ssh密碼登陸:
ssh-keygen
二、增長公鑰到openstack環境中:
nova keypair-add --pub-key ~/.ssh/id_rsa.pub demo-key
三、驗證是否配置成功:
nova keypair-list nova flavor-list
四、建立實例:
複製代碼 代碼以下:
nova boot --flavor m1.tiny --image cirros-0.3.2-x86_64 --nic netid=DEMO_NET_ID\
--security-group default --key-name demo-key demo-instance1
說明:
DEMO_NET_ID:指的是nova net-list的ID。
demo-instance1指的是虛擬機的名字。
例如個人成功執行以下:
五、使用nova list進行查看。
從這裏咱們看到我這上面有一個ip地址192.168.44.17.這個地址就是浮動IP。
六、配置浮動IP
浮動ip
nova-manage floating create --ip_range=192.168.44.16/28
查看可用地址
nova-manage floating list
nova floating-ip-create
給建立的虛擬機綁定浮動ip,這個7bc0086…就是我以前建立的虛擬機的ID。後面接上IP地址便可。
nova add-floating-ip 7bc00086-1870-4367-9f05-666d5067ccff 192.168.44.17
監聽
cpdump -n -i eth0 icmp
在controller上:
nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
七、使用下面的命令能夠輸出一個url地址:
nova get-vnc-console tfjt novnc
八、咱們能夠在瀏覽器中進行訪問。
到這裏爲止,咱們的雲服務器就算完成了。能夠在瀏覽器上訪問咱們的雲服務器,怎麼樣是否是很激動。
界面服務(dashboard)
上面咱們能夠看到不少操做是在終端進行的,那麼確定是有界面版的,因此咱們在computer02中進行配置。
一、安裝服務
yum install memcached python-memcached mod_wsgi openstack-dashboard
二、文件配置。
在controller中
配置/etc/openstack-dashboard/local_settings。修改成以下內容。
ALLOWED_HOSTS = ['*'] CACHES = { 'default': { 'BACKEND' : 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION' : '127.0.0.1:11211' } } OPENSTACK_HOST = "controller"
三、鏈接
setsebool -P httpd_can_network_connect on service httpd start # service memcached start # chkconfig httpd on # chkconfig memcached on
四、瀏覽器中訪問。
http://192.168.44.147/dashboard/project/
用戶名就是咱們以前配置的admin,密碼是ADMIN_PASS
在這個界面版裏面的各類操做我這裏就不細說了,能夠本身去體驗。
在這裏能夠看到咱們的雲服務器實例。
雲硬盤服務(cinder)
瞭解過阿里雲或者騰訊雲的就知道,裏面都有一個雲硬盤服務,能夠給咱們的機器增長磁盤。
在controller端:
yum stall openstack-cinde openstack-config --set /etc/cinder/cinder.conf \ database connection mysql://cinder:CINDER_DBPASS@controller/cinder mysql> CREATE DATABASE cinder; mysql> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \ IDENTIFIED BY 'CINDER_DBPASS'; mysql> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \ IDENTIFIED BY 'CINDER_DBPASS';
建立數據庫表:
# su -s /bin/sh -c "cinder-manage db sync" cinder
建立用戶並賦予角色:
$ keystone user-create --name=cinder --pass=CINDER_PASS--email=cinder@example.com $ keystone user-role-add --user=cinder --tenant=service --role=admin
權限控制配置:

配置文件中:
vi /etc/tgt/targets.conf
include /etc/cinder/volumes/*
啓動服務:
# service openstack-cinder-volume start # service tgtd start # chkconfig openstack-cinder-volume on # chkconfig tgtd on
建立磁盤:
cinder create --display-name myVolume 1
查看磁盤列表:
cinder list
而後再界面端查看雲硬盤的配置並進行掛載:
在雲服務器上掛載磁盤:
$ mkfs.ext3 /dev/vdb1 $ mkdir /mnt/test $ mount /dev/vdb1 /mnt/test $ mount $ fdisk /dev/vdb Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel with disk identifier 0x64817ea3. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won't be recoverable.

總結:整個操做流程很是複雜,我也是花了幾天才慢慢搭建好的,這其實也就是個基礎,給的實際上是一個思路,後面須要怎樣的擴展能夠根據本身的業務須要進行不一樣的設置。對於不明白的地方能夠查閱官方文檔。總之很複雜
