1.基础配置

操作系统使用CentOS-7.0-x86_64-*.iso，安装过程省略，本文採用yum源安装。

(1).导入第三方安装源

[root@node ~]# rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

[root@node ~]# rpm -Uvhhttp://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el7.rf.x86_64.rpm

[root@node ~]# yum installhttp://repos.fedorapeople.org/repos/openstack/openstack-havana/rdo-release-havana-9.noarch.rpm

(2).配置/etc/hosts文件

[root@node ~]# vi /etc/hosts

127.0.0.1  localhost localhost.localdomain localhost4 localhost4.localdomain4

::1        localhost localhost.localdomain localhost6localhost6.localdomain6

192.168.1.2  openstack

192.168.1.3  node

(3).配置网络

[root@node ~]# vi/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"

BOOTPROTO="static"

HWADDR="E4:1F:13:45:AB:C1"

ONBOOT="yes"

IPADDR=192.168.1.3

NETMASK=255.255.255.0

GATEWAY=192.168.1.1

TYPE="Ethernet"

[root@openstack~]# vi /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE="eth1"

BOOTPROTO="none"

HWADDR="E4:1F:13:45:AB:C3"

ONBOOT="yes"

TYPE="Ethernet"

(4).关闭selinux：

[root@node ~]# more/etc/selinux/config

#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 - SELinux is fully disabled.

SELINUX=disabled

#SELINUXTYPE= type of policy in use. Possible values are:

#      targeted - Only targeted network daemons are protected.

#      strict - Full SELinux protection.

SELINUXTYPE=targeted

[root@node~]# setenforce 0

(5).改动/etc/sysctl.conf參数：

[root@node ~]# vi/etc/sysctl.conf

……………………

net.ipv4.ip_forward= 1

……………………

[root@node ~]#sysctl -p                   #使sysctl.conf配置生效

2.安装配置NTPclient

(1).安装NTPclient服务：

[root@node ~]# yum -y installntpdate

(2).设置时间同步：

[root@node ~]#ntpdate192.168.1.2

31 Mar 16:17:03ntpdate[5848]: the NTP socket is in use, exiting

(3).设置计划任务：

[root@node ~]# crontab-e

插入下行内容：

*/5 * * * * ntpdate 192.168.1.2>> /var/log/ntpdate.log

3.环境变量设置

改动.bash_profile文件，加入下面參数：

[root@node ~]# vi.bash_profile

………………

exportOS_USERNAME=admin

exportOS_TENANT_NAME=admin

exportOS_PASSWORD=password

exportOS_AUTH_URL=http://192.168.1.2:5000/v2.0

exportSERVICE_ENDPOINT=http://192.168.1.2:35357/v2.0

exportSERVICE_TOKEN=12dd70ede7c9d9d3ed3c

………………

运行以下的命令使变量即时生效：

[root@node ~]# source.bash_profile

4.安装配置libvirt服务

(1).安装libvirt服务：

[root@node ~]#yum -y install qemu-kvm libvirt

(2)启动libvirt服务：

[root@node ~]# servicelibvirtd start

(3)查看net-list，发现default：

[root@node ~]# virshnet-list

Name                State     Autostart     Persistent

--------------------------------------------------

default             active     yes          yes

(4)删除default。即virbr0：

[root@node ~]# virshnet-destroy default

Networkdefault destroyed

[root@node ~]# virshnet-undefine default

Networkdefault has been undefined

(5)重新启动libvirtd服务，设置开机自启动：

[root@node ~]# servicelibvirtd restart

[root@node ~]# chkconfiglibvirtd on

5.安装MySQLclient

(1).安装mysqlclient

[root@node ~]#yum -y install maridb

(2).检查mysql数据库连通性

[root@node ~]# mysql -h192.168.1.2 -unova -pnova

Welcome to the MySQLmonitor.  ………………

mysql> quit;

Bye

6.安装配置Nova服务

(1)安装nova-compute、nova-network、nova-scheduler

[root@node ~]#yum -y install openstack-nova-computeopenstack-nova-network openstack-nova-scheduler

(2).改动nova配置文件

[root@node ~]#vi /etc/nova/nova.conf

[DEFAULT]

my_ip = 192.168.1.3

auth_strategy = keystone

state_path =/letv/openstack/lib/nova

verbose=True

allow_resize_to_same_host= true

rpc_backend =nova.openstack.common.rpc.impl_qpid

qpid_hostname = 192.168.1.2

libvirt_type = kvm

glance_api_servers = 192.168.1.2:9292

novncproxy_base_url =http://192.168.1.2:6080/vnc_auto.html

vncserver_listen = 192.168.1.3

vncserver_proxyclient_address= 192.168.1.3

vnc_enabled = true

vnc_keymap = en-us

network_manager =nova.network.manager.FlatDHCPManager

firewall_driver =nova.virt.firewall.NoopFirewallDriver

multi_host = True

flat_interface = eth1

flat_network_bridge = br1

public_interface = eth0

instance_usage_audit =True

instance_usage_audit_period= hour

notify_on_state_change =vm_and_task_state

notification_driver =nova.openstack.common.notifier.rpc_notifier

compute_scheduler_driver=nova.scheduler.simple.SimpleScheduler

[hyperv]

[zookeeper]

[osapi_v3]

[conductor]

[keymgr]

[cells]

[database]

sql_connection=mysql://nova:nova@192.168.1.2/nova

[image_file_url]

[baremetal]

[rpc_notifier2]

[matchmaker_redis]

[ssl]

[trusted_computing]

[upgrade_levels]

[matchmaker_ring]

[vmware]

[spice]

[keystone_authtoken]

auth_host = 192.168.1.2

auth_port = 35357

auth_protocol = http

admin_user = nova

admin_tenant_name =service

admin_password = service

因上管理节点nova.conf配置文件里改动了instances实例存放的位置。还须要作一下操作：

改动路径，设置文件夹权限：

[root@node ~]# cp-r /var/lib/nova/ /openstack/lib/

[root@node ~]# chown-R nova:nova /openstack/lib/nova/

(3).启动nova相关服务。设置开机自启动

[root@node ~]# servicemessagebus start

[root@node ~]# chkconfigmessagebus on

[root@node ~]# serviceopenstack-nova-compute start

[root@node ~]# serviceopenstack-nova-network start

[root@node ~]# chkconfigopenstack-nova-compute on

[root@node ~]# chkconfigopenstack-nova-network on

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

OpenStack其它经常使用命令：

1.listnova服务，包括管理节点和计算节点

[root@openstack~]# nova service-list

+------------------+-------------+----------+---------+-------+----------------------------+-----------------+

| nova-scheduler  | node      | internal | enabled | up    | 2014-03-31T08:59:52.000000| -               |

2.查看计算节点：

[root@node ~]# novahypervisor-list

+----+---------------------+

| ID | Hypervisorhostname |

+----+---------------------+

| 1  | openstack          |

| 2  |node             |

+----+---------------------+

3.查看虚拟机模板配置：

[root@node ~]# novaflavor-list

+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+

| ID | Name     | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor |Is_Public |
