二、基础服务部署

2.1、数据库服务(Mysql): Openstack的各个组件都需要mysql保存数据

[root@linux-node1 ~]# yum install -y mysql-server

[root@linux-node1 ~]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

[root@linux-node1 ~]# vim /etc/my.cnf

default-storage-engine = innodb

innodb_file_per_table

collation-server = utf8_general_ci

init-connect = 'SET NAMES utf8'

character-set-server = utf8

[root@linux-node1 ~]# service mysqld start

[root@linux-node1 ~]# chkconfig mysqld on

[root@linux-node1 ~]# mysql

create database keystone; ##认证服务

grant all on keystone.* to keystone@'10.0.0.0/255.255.255.0' identified by 'keystone';

create database glance; ##镜像服务

grant all on glance.* to glance@'10.0.0.0/255.255.255.0' identified by 'glance';

create database nova; ##计算服务

grant all on nova.* to nova@'10.0.0.0/255.255.255.0' identified by 'nova';

create database neutron; ##网络服务

grant all on neutron.* to neutron@'10.0.0.0/255.255.255.0' identified by 'neutron';

create database cinder; ##存储服务

grant all on cinder.* to cinder@'10.0.0.0/255.255.255.0' identified by 'cinder';

exit

2.2、消息代理(Rabbitmq):消息队列是交通枢纽的作用，在Openstack云平台的沟通过程中需要使用消息队列

[root@linux-node1 ~]# yum install -y rabbitmq-server

[root@linux-node1 ~]# /etc/init.d/rabbitmq-server start

Starting rabbitmq-server: SUCCESS

rabbitmq-server.

[root@linux-node1 ~]# chkconfig rabbitmq-server on

[root@linux-node1 ~]# /usr/lib/rabbitmq/bin/rabbitmq-plugins list ##列出所有的插件

[root@linux-node1 ~]# /usr/lib/rabbitmq/bin/rabbitmq-plugins enable rabbitmq_management ##启用web监控插件

[root@linux-node1 ~]# /etc/init.d/rabbitmq-server restart

[root@linux-node1 ~]# netstat -lntup|grep 5672

tcp 0 0 0.0.0.0:15672 ##web界面端口 0.0.0.0:* LISTEN 13778/beam.smp

tcp 0 0 0.0.0.0:55672 ##web界面端口 0.0.0.0:* LISTEN 13778/beam.smp

tcp 0 0 :::5672 ##rabbitmq服务端口 :::* LISTEN 13778/beam.smp

2.2.1、客户端登陆http://10.0.0.101:15672 用户名和密码都是guest

2.2.2、Rabbitmq基本管理

[root@linux-node1 ~]# rabbitmqctl change_password guest openstack ##修改默认的guest密码

[root@linux-node1 ~]# rabbitmqctl add_user openstack openstack ##添加用户

[root@linux-node1 ~]# rabbitmqctl set_user_tags openstack administrator ##设置用户角色

[root@linux-node1 ~]# rabbitmqctl list_users ##列出用户

三、Openstack安装部署

3.1、身份认证服务(Keystone): 用户认证、服务目录

用户和认证:用户权限与用户行为跟踪

服务目录:提供一个服务目录，包括所有服务项与相关API的端点

[root@linux-node1 ~]# vim /etc/yum.repos.d/icehouse.repo ##安装i版的openstack时,需要自己编辑repo文件

[icehouse]
name=Extra icehouse Packages for Enterprise Linux 6 - $basearch
baseurl=https://repos.fedorapeople.org/repos/openstack/EOL/openstack-icehouse/epel-6/
failovermethod=priority
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

[root@linux-node1 ~]# yum install -y openstack-keystone python-keystoneclient

[root@linux-node1 ~]# keystone-manage pki_setup --keystone-user keystone --keystone-group keystone

Using configuration from /etc/keystone/ssl/certs/openssl.conf

[root@linux-node1 ~]# chown -R keystone:keystone /etc/keystone/ssl/

[root@linux-node1 ~]# chmod -R o-wrx /etc/keystone/ssl/

[root@linux-node1 ~]# vim /etc/keystone/keystone.conf ##修改配置文件

admin_token=ADMIN

connection=mysql://keystone:[email protected]/keystone

debug=true ##在生产环境不建议打开，还是false

log_file=/var/log/keystone/keystone.log

[root@linux-node1 ~]# keystone-manage db_sync ##同步文件到数据库

[root@linux-node1 ~]# mysql -e "use keystone;show tables;" ##确定表已经建立

3.3.1、Nova控制节点安装(Install Compute controller services)

在控制节点安装时，需要安装除了nova-compute之外的其它的所有的nova服务

[root@linux-node1 ~]# yum install -y openstack-nova-api openstack-nova-cert openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler python-novaclient

3.3.2、Nova计算节点安装(Configure a compute node)

nova-comupte:一般运行在计算节点上，通过Message Queue接收并管理VM的生命周期

nova-comupte:通过Libvirt管理KVM，通过XenAPI管理Xen等

[root@linux-node2 ~]# yum install -y qemu-kvm libvirt openstack-nova-compute python-novaclient

在linux-node1上把Nova的配置文件scp到linux-node2上

[root@linux-node1 ~]# scp /etc/nova/nova.conf [email protected]:/etc/nova

[root@linux-node2 ~]# vim /etc/nova/nova.conf

vncserver_proxyclient_address=10.0.0.102

[root@linux-node2 ~]# /etc/init.d/libvirtd start

Starting libvirtd daemon:

[root@linux-node2 ~]# /etc/init.d/messagebus start

Starting system message bus:

[root@linux-node2 ~]# /etc/init.d/openstack-nova-compute start

Starting openstack-nova-compute: [ OK ]

[root@linux-node2 ~]# chkconfig libvirtd on

[root@linux-node2 ~]# chkconfig messagebus on

[root@linux-node2 ~]# chkconfig openstack-nova-compute on

在linux-node1上验证是否上线

3.5、Add the Dashboard(Horizon)

Horizon:主要是为openstack提供一个web的管理界面

[root@linux-node1 ~]# yum install -y httpd mod_wsgi memcached python-memcached openstack-dashboard

出现下面的报错:

Error: Package: python-django-horizon-2014.1.5-1.el6.noarch (icehouse)

Requires: Django14

Error: Package: python-django-openstack-auth-1.1.5-1.el6.noarch (icehouse)

Requires: Django14

Error: Package: python-django-compressor-1.3-2.el6.noarch (icehouse)

Requires: Django

You could try using --skip-broken to work around the problem

You could try running: rpm -Va --nofiles --nodigest

[root@linux-node1 ~]# rz Django14-1.4.21-1.el6.noarch.rpm ##从网上找到了rpm包,然后上传到控制节点

[root@linux-node1 ~]# rpm -ivh Django14-1.4.21-1.el6.noarch.rpm

[root@linux-node1 ~]# yum install -y httpd mod_wsgi memcached python-memcached openstack-dashboard

[root@linux-node1 ~]# /etc/init.d/memcached start

CACHES = {

'LOCATION' : '127.0.0.1:11211',

}

OPENSTACK_HOST = "10.0.0.101" ##keystone的ip地址

[root@linux-node1 ~]# /etc/init.d/httpd start

[root@linux-node1 ~]# chkconfig httpd on

此时就可以在浏览器上管理了: http://10.0.0.101/dashboard

在整个过程中碰到的两个小问题及解决方法:

1、创建完成demo之后，有一个”无法连接到Neutron ”的报错，网上查询得知：

在Icehouse版本创建虚拟机会遇到错误：无法连接到Neutron.的报错，但是虚拟机还可以创建成功，这个是一个已知的bug，可以通过修改源码解决；还有一种情况，就是你的Neutron真的无法连接，要查看服务和监听端口9696是否正常。

在class FloatingIpManager类里少了is_supported的方法，这个是一个bug，可以通过手动修改解决。

def is_simple_associate_supported(self):

# NOTE: There are two reason that simple association support

# needs more considerations. (1) Neutron does not support the

# default floating IP pool at the moment. It can be avoided

# in case where only one floating IP pool exists.

# (2) Neutron floating IP is associated with each VIF and

# we need to check whether such VIF is only one for an instance

# to enable simple association support.

return False

#在这个类的最下面，增加下面的方法，注意缩进。

def is_supported(self):

network_config = getattr(settings, 'OPENSTACK_NEUTRON_NETWORK', {})

return network_config.get('enable_router', True)

修改完毕后，需要重启apache才可以生效/etc/init.d/httpd restart

错误原因：websockify版本太低，升级websockify版本即可。

哈希表(散列表)出现的原因在顺序表中查找时，需要从表头开始，依次遍历比较a[i]与key的值是否相等，直到相等才返回索引i；在有序表中查找时，我们经常使用的是二分查找，通过比较key与a[i]的大小来折半查找，直到相等时才返回索引i。最终通过索引找到我们要找的元素。但是，这两种方法的效率都依赖于查找中比较的次数。我们有一种想法，能不能不经过比较，而是直接通过关键字key一次得到所要的结果呢？这时，
