本次实验环境
1 Centos6.5 X86_64位 英文版minimal安装环境
2 openstack源使用本地源（最后有本地源下载地址：CentOS6.5 链接：http://pan.baidu.com/s/1sl3wDzv 密码：n2ze Openstack-icehouse: 链接：http://pan.baidu.com/s/1c2JwlK8 密码：fw6y）
3 双节点（controller、compute）
4 每个节点双网卡:
eth0 管理、公共
eth1 私有、提供虚拟机IP地址
5 使用virtualbox虚拟化软件
性能需求：
controller：2G内存、100G硬盘、双网卡
compute：4G内存、120G硬盘、双网卡
virtualbox网络设置如下图：
具体步骤如下：
1 安装系统
使用virtualBox创建两台虚拟机，一台为controller节点、一台为compute节点。
创建的虚拟机配置如下图所示：
以上为控制点的主要配置。计算点配置类似，就是内存设置大点即可。
在安装系统过程中，需要注意以下几点
（1）建议选择全英文安装，这样在安装过程中会很快
（2）时区选择时，选择Asia/Shanghai时区，取消系统自动更新时区勾选
（3）分区时，一般选择自定义分区。本人的分区主要有：根目录50G、/boot分区200M、swap分区（设置为内存的2倍）、创建一块没有挂载点的分区（10G，留着以后做cinder和swift，计算点就设置两块没有挂载点的分区）
（4）选择系统类型时，建议双节点全部选择为minimal，这样安装就会节约很多时间
2 基本设置
系统正常安装后做如下设置：
controller节点：
（1）[root@controller ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter mangle na[ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
[root@controller ~]# chkconfig iptables off
[root@controller ~]#
（2）修改selinux为disabled
[root@controller ~]# cat /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
（3）修改主机名
[root@controller ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.20.0.200 controller
10.20.0.201 compute
[root@controller ~]#
（4）关闭iptables服务，关闭开机自启
[root@controller ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter mangle na[ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
[root@controller ~]# chkconfig iptables off
[root@controller ~]#
（5）修改yum源，本次实验使用的源为本地源，所以我们需要把系统自带的源更改。把/etc/yum.repos.d/目录下的文件进行备份，然后创建local.repo文件
[root@controller ~]# cat /etc/yum.repos.d/local.repo
[centos]
baseurl=file:///opt/centos
gpgcheck=0
enabled=1
[openstack-icehouse]
baseurl=file:///opt/iaas-repo
gpgcheck=0
enabled=1
[root@controller ~]#
以上都是controller点的前期准备工作。
compute节点：
（1）修改网卡
[root@compute ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=08:00:27:C1:53:F2
TYPE=Ethernet
UUID=30923f68-51f3-41e5-bb79-6061b213378a
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=no
IPADDR=10.20.0.201
NETMASK=255.255.255.0
GATEWAY=10.20.0.1
[root@compute ~]#
（2）修改主机名
[root@compute ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.20.0.200 controller
10.20.0.201 compute
[root@compute ~]#
（3）修改yum源，我们在控制点上安装FTP服务器，然后计算点所使用的源全部来自此服务器。先把/etc/yum.repos.d/目录下的文件进行备份，然后创建local.repo文件
[root@compute ~]# cat /etc/yum.repos.d/local.repo
[centos]
baseurl=ftp://10.20.0.200/centos
gpgcheck=0
enabled=1
[openstack-icehouse]
baseurl=ftp://10.20.0.200/iaas-repo/
gpgcheck=0
enabled=1
[root@compute ~]#
以上为计算点的前期准备工作
测试：
控制点ping计算点
[root@controller ~]# ping -c 4 compute
PING compute (10.20.0.201) 56(84) bytes of data.
64 bytes from compute (10.20.0.201): icmp_seq=1 ttl=64 time=0.258 ms

rtt min/avg/max/mdev = 0.258/0.371/0.444/0.071 ms
[root@controller ~]#
计算点ping控制点
[root@compute ~]# ping -c 4 controller
PING controller (10.20.0.200) 56(84) bytes of data.
64 bytes from controller (10.20.0.200): icmp_seq=1 ttl=64 time=0.176 ms

--- controller ping statistics ---
4 packets transmitted, 4 received, 0% packet loss, time 3007ms
rtt min/avg/max/mdev = 0.176/0.208/0.220/0.023 ms
[root@compute ~]#
以上都配置完成后，我们重启两台机器
重启完成后，我们利用FTP上传工具把源上传到controller节点的/home目录。上传完成后，我们进行以下的操作
[root@controller home]# mount -o loop CentOS6.5.iso /mnt/
[root@controller home]# cd /mnt/
[root@controller mnt]# ll

[root@controller mnt]# cp -rfv * /opt/centos
复制完成后，我们取消Centos6.5的挂载，然后再把Openstack源进行挂载
[root@controller ~]# umount /mnt/
[root@controller ~]# mount -o loop /home/openstack.iso /mnt/
[root@controller ~]# cd /mnt/
[root@controller mnt]# ll
total 4
drwxrwxr-x 6 nobody nobody 2048 Nov 13 2015 iaas-repo
drwxrwxr-x 2 nobody nobody 2048 Mar 6 2015 images
[root@controller mnt]# cp -rfv * /opt/
以上这两步完成后，我们在controller节点上安装ftp服务：
[root@controller ~]# yum install vsftpd -y
Loaded plugins: fastestmirror, priorities
Repository 'centos' is missing name in configuration, using id
Repository 'openstack-icehouse' is missing name in configuration, using id
Loading mirror speeds from cached hostfile
Setting up Install Process
Package vsftpd-2.2.2-11.el6_4.1.x86_64 already installed and latest version
Nothing to do
[root@controller ~]#
然后我们把ftp的目录进行修改，允许匿名进行访问，只要在/etc/vsftpd/vsftpd.conf文件加上：anon_root=/opt/即可
然后重启ftp服务，并设置开机自启：
[root@controller ~]# service vsftpd restart
Shutting down vsftpd: [ OK ]
Starting vsftpd for vsftpd: [ OK ]
[root@controller ~]# chkconfig vsftpd on
[root@controller ~]#
最后我们到计算点上进行验证：
[root@compute ~]# yum update
Loaded plugins: fastestmirror, priorities
Repository 'centos' is missing name in configuration, using id
Repository 'openstack-icehouse' is missing name in configuration, using id

[root@compute ~]#
yum设置完成后，接着在controller节点安装、配置ntp服务：
[root@controller ~]# yum install -y ntp
Loaded plugins: fastestmirror, priorities
Repository 'centos' is missing name in configuration, using id
Repository 'openstack-icehouse' is missing name in configuration, using id
Loading mirror speeds from cached hostfile
Setting up Install Process
Package ntp-4.2.6p5-1.el6.centos.x86_64 already installed and latest version
Nothing to do
[root@controller ~]#
修改ntp配置文件/etc/ntp.conf：
[root@controller ~]# cat /etc/ntp.conf

[root@controller ~]#
启动ntp，并设置开机自启：
[root@controller ~]# service ntpd restart
Shutting down ntpd: [ OK ]
Starting ntpd: [ OK ]
[root@controller ~]# chkconfig ntpd on
[root@controller ~]#
然后到计算点同步时间：
[root@compute ~]# yum install ntp
Loaded plugins: fastestmirror, priorities
Repository 'centos' is missing name in configuration, using id
Repository 'openstack-icehouse' is missing name in configuration, using id
Loading mirror speeds from cached hostfile
Setting up Install Process

[root@compute ~]# ntpdate controller
14 Dec 02:56:14 ntpdate[10847]: adjust time server 10.20.0.200 offset 0.250648 sec
[root@compute ~]#
然后我们安装qpid服务，用于openstack各个组件的消息通讯服务：
[root@controller ~]# yum install qpid-cpp-server -y
Loaded plugins: fastestmirror, priorities
Repository 'centos' is missing name in configuration, using id
Repository 'openstack-icehouse' is missing name in configuration, using id
Loading mirror speeds from cached hostfile
Setting up Install Process
Package qpid-cpp-server-0.18-18.el6.x86_64 already installed and latest version
Nothing to do
设置qpid认证为否：

[root@controller ~]#
以上步骤配置完成后，系统的基本设置就OK了，接下来我们要先安装openstack所需要的基础服务。
3 安装openstack所需要的基础服务，以下服务的安装都可以通过脚本进行执行
控制点：
（1）安装mysql数据库，执行脚本install-mysql.sh
（2）安装keystone服务，执行脚本install-keystone.sh
验证：
[root@controller ~]# keystone user-list
+----------------------------------+---------+---------+-------+
| id | name | enabled | email |
+----------------------------------+---------+---------+-------+
| 03bc017104c048fe9ccb3b68a73e8afb | admin | True | |
| c89c26a82e944083a0a165c16231a42e | demo | True | |
+----------------------------------+---------+---------+-------+
[root@controller ~]#
（3）安装glance服务，执行脚本install-glance.sh
验证：
[root@controller ~]# glance image-list
+--------------------------------------+--------------------------+-------------+--------+
| ID | Name | Disk Format | Container Format | Size | Status |
+--------------------------------------+--------------------------+-------------+--------+
| | | | | | |
+--------------------------------------+--------------------------+-------------+--------+
[root@controller ~]#
（4）安装nova服务，执行脚本install-nova-controller.sh
安装完成后，我们需要到计算节点把nova服务也安装一下，执行脚本：install-nova-compute.sh
两个节点都安装成功后，我们在控制节点进行验证：
[root@controller ~]# nova service-list
+------------------+------------+----------+---------+-------+----------------------------+-----------------+
| Binary | Host | Zone | Status | State | Updated_at | Disabled Reason |
+------------------+------------+----------+---------+-------+----------------------------+-----------------+
| nova-cert | controller | internal | enabled | up | 2016-12-13T19:05:22.000000 | - |
| nova-consoleauth | controller | internal | enabled | up | 2016-12-13T19:05:20.000000 | - |
| nova-conductor | controller | internal | enabled | up | 2016-12-13T19:05:19.000000 | - |
| nova-scheduler | controller | internal | enabled | up | 2016-12-13T19:05:20.000000 | - |
| nova-compute | compute | nova | enabled | up | 2016-12-13T19:05:18.000000 | - |
+------------------+------------+----------+---------+-------+----------------------------+-----------------+
[root@controller ~]#
（5）安装neutron服务，在安装之前我们设置一下两个节点的第二块网卡配置：
[root@controller ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
HWADDR=08:00:27:B5:CB:CA
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
IPADDR=172.16.100.10
NETMASK=255.255.255.0
GATEWAY=172.16.100.1
[root@controller ~]#
[root@compute ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
HWADDR=08:00:27:DE:5A:BD
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
IPADDR=172.16.100.20
NETMASK=255.255.255.0
GATEWAY=172.16.100.1
两块网卡设置成功后，先在控制点执行：install-neutron-controller.sh
验证：
[root@controller ~]# neutron agent-list
+--------------------------------------+--------------------+------------+-------+----------------+
| id | agent_type | host | alive | admin_state_up |
+--------------------------------------+--------------------+------------+-------+----------------+
| 32ba7f2f-ff57-4774-b92f-467e5d7df045 | DHCP agent | controller | :-) | True |
| 98ecd824-cc30-4d8b-b88f-9e31e1da89c1 | L3 agent | controller | :-) | True |
| d7bc4acd-955e-4e82-bf18-49c832d7de3a | Open vSwitch agent | controller | :-) | True |
+--------------------------------------+--------------------+------------+-------+----------------+
[root@controller ~]#
然后到计算点执行：install-neutron-compute.sh
安装完成后，我们再到控制点进行验证：
[root@controller ~]# neutron agent-list
+--------------------------------------+--------------------+------------+-------+----------------+
| id | agent_type | host | alive | admin_state_up |
+--------------------------------------+--------------------+------------+-------+----------------+
| 077df758-8178-4558-997c-6c37210ece00 | Metadata agent | compute | :-) | True |
| 32ba7f2f-ff57-4774-b92f-467e5d7df045 | DHCP agent | controller | :-) | True |
| 78f791d7-8801-4740-82be-462b9360480b | DHCP agent | compute | :-) | True |
| 97e56832-b467-442c-a3ac-edb2d31146a9 | Open vSwitch agent | compute | :-) | True |
| 98ecd824-cc30-4d8b-b88f-9e31e1da89c1 | L3 agent | controller | :-) | True |
| d7bc4acd-955e-4e82-bf18-49c832d7de3a | Open vSwitch agent | controller | :-) | True |
+--------------------------------------+--------------------+------------+-------+----------------+
[root@controller ~]#
如果有以上提示，说明我们neutron安装成功。如果提示不对，或者没有以上的提示，那我们需要去/var/log/neutron目录下查看对应的日志文件。
4 以上的基础服务安装成功后，我们需要在控制点安装openstack-dashboard服务，这个服务提供web操作功能：
[root@controller ~]# yum install -y memcached python-memcached mod_wsgi openstack-dashboard--2014.1.3-1.el6
（openstack-dashboard需要加上版本号，要是不加会提示错误）
安装结束后，设置openstack-dashboard，修改/etc/openstack-dashboard/local_settings
ALLOWED_HOSTS = ['10.20.0.200', 'localhost']
OPENSTACK_HOST = "controller"
取消：
CACHES = {
'default': {
'BACKEND' : 'django.core.cache.backends.memcached.MemcachedCache',
'LOCATION' : '127.0.0.1:11211',
}
}
前的注释
启动httpd、memcached服务，并且设置开机自启：
[root@controller ~]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 10.20.0.200 for ServerName
[ OK ]
[root@controller ~]# service memcached restart
Stopping memcached: [ OK ]
Starting memcached: [ OK ]
[root@controller ~]# chkconfig httpd on
[root@controller ~]# chkconfig memcached on
[root@controller ~]#
完成以上步骤后，我们到浏览器中打开：10.20.0.200/dashboard
账号:admin 密码:000000
至此，我们的平台基本搭建成功。接下来我们开启一台虚拟机试试：
1 创建网络
[root@controller ~]# keystone tenant-list
