4.OpenStack介绍
OpenStack 是一个开源的 IaaS（基础设施及服务）云计算平台，让任何人都可以自行建立和提供云端运算服务。OpenStack 由一系列相互关联的项目提供云基础设施解决方案的各个组件，核心项目（9 个）：
计算 (Compute) - Nova；
网络和地址管理 - Neutron；
对象存储 (Object) - Swift；
块存储 (Block) - Cinder；
身份 (Identity) - keystone；
镜像 (Image) - Glance；
UI 界面 (Dashboard) - Horizon；
测量 (Metering) - Ceilometer；
编配 (Orchestration) – Heat；

二、管理节点安装(OpenStack)
1.基础配置
操作系统使用CentOS-6.4-x86_64-minimal.iso，安装过程省略，本文采用yum源安装。
(1).导入第三方安装源
# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
# rpm -Uvh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
# yum install http://repos.fedorapeople.org/repos/openstack/openstack-havana/rdo-release-havana-7.noarch.rpm
(2).配置/etc/hosts文件
# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.10.21 openstack
192.168.10.22 node01
(3).配置网络
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO="static"
HWADDR="E4:1F:13:45:AB:C8"
ONBOOT="yes"
IPADDR=192.168.10.21
NETMASK=255.255.255.0
GATEWAY=192.168.10.1
TYPE="Ethernet"
# vi /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE="eth1"
BOOTPROTO="none"
HWADDR="E4:1F:13:45:AB:CA"
ONBOOT="yes"
TYPE="Ethernet"
(4).关闭selinux：
# 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
# setenforce 0
(5).修改/etc/sysctl.conf参数：
# vi /etc/sysctl.conf
……………………
net.ipv4.ip_forward = 1
……………………
#sysctl -p #使sysctl.conf配置生效
2.安装配置NTP服务
(1).安装NTP服务：
# yum -y install ntp
(2).配置NTP服务：
# vi /etc/ntp.conf
driftfile /var/lib/ntp/drift
restrict default ignore
restrict 127.0.0.1
restrict 192.168.10.0 mask 255.255.255.0 nomodify notrap
server ntp.api.bz
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10
keys /etc/ntp/keys
(3).启动NTP服务,设置开机自启动：
# service ntpd start
# chkconfig ntpd on
3.配置安装MySQL：
(1).安装MySQL服务：
# yum -y install mysql mysql-server MySQL-python
(2).修改MySQL配置文件：
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
bind-address = 0.0.0.0 #设置监听IP地址0.0.0.0
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
(3).启动MqSQL服务，设置开机自启动：
# service mysqld start
# chkconfig mysqld on
(4).修改MySQL密码为passwd：
# mysqladmin -uroot password 'passwd'; history -c
4.安装配置qpid服务
(1).安装qpid服务：
# yum -y install qpid-cpp-server memcached
(2).修改/etc/qpidd.conf配置文件,将auth设置为no：
@openstack ~]# vi/etc/qpidd.conf
……………………
auth=no
(3).启动qpid服务，设置开机启动：
# service qpidd start
# chkconfig qpidd on
(4).安装OpenStack工具包：
~]# yuminstall -y openstack-utils
5.安装配置KeyStone
5.1.初始化KeyStone：
(1).安装KeyStone服务：
oot@openstack ~]# yum -y install openstack-keystone
(2).创建keystone数据库，修改配置文件中的数据库链接：
# openstack-db --init --service keystone
(3).修改配置文件中的数据库链接：
# openstack-config --set /etc/keystone/keystone.conf sql connection mysql://keystone:keystone@localhost/keystone
(4).使用openssl随即生成一个令牌，将其存储在配置文件中：
# export SERVICE_TOKEN=$(openssl rand -hex 10) //随机生成SERVICE_TOKEN值，请牢记
# export SERVICE_ENDPOINT=http://127.0.0.1:35357/v2.0
# mkdir /root/config
# echo $SERVICE_TOKEN > /root/config/ks_admin_token.txt
# cat /root/config/ks_admin_token .txt
12dd70ede7c9d9d3ed3c
# openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_token $SERVICE_TOKEN
*注：将生成的SERVICE_TOKEN值写入文件中保存，以备后续使用，后面涉及到的SERVICE_TOKEN值都是在ks_admin_token.txt文件中获取的。所以一旦写入文件，不要再次运行命令生成SERVICE_TOKEN，否则前后不一致会为调试带来麻烦。
(5).默认情况下keysonte使用PKI令牌。创建签名密钥和证书：
# keystone-manage pki_setup --keystone-user keystone --keystone-group keystone
# chown -R keystone:keystone /etc/keystone/* /var/log/keystone/keystone.log
(6).启动keystone服务，设置开机自启动：
# service openstack-keystone start
# chkconfig openstack-keystone on
5.2.定义Users、Tenants and Roles
(1).修改.bash_profile文件，添加以下参数：
# vi .bash_profile
………………
export OS_USERNAME=admin
export OS_TENANT_NAME=admin
export OS_PASSWORD=password
export OS_AUTH_URL=http://127.0.0.1:5000/v2.0
export SERVICE_ENDPOINT=http://127.0.0.1:35357/v2.0
export SERVICE_TOKEN=12dd70ede7c9d9d3ed3c
………………
执行下面的命令使变量即时生效：
# source .bash_profile
(2).为管理员用户创建一个tenant，为openstack其他服务的用户创建一个tenant：
# keystone tenant-create --name=admin --description='Admin Tenant'
# keystone tenant-create --name=service --description='Service Tenant'
(3).创建一个管理员用户admin：
# keystoneuser-create --name=admin --pass=password --email=keystone@chensh.net
(4).创建一个管理员角色admin：
# keystone role-create --name=admin
(5).将角色添加到用户：
# keystone user-role-add --user=admin --tenant=admin --role=admin
5.3.定义Services 和 API Endpoints
(1).为KeyStone创建一个服务：
# keystoneservice-create --name=keystone --type=identity --description="KeystoneIdentity Service"
(2).使用服务ID创建一个endpoint：
# vi /root/config/keystone.sh
#!/bin/bash
my_ip=192.168.10.21
service=$(keystone service-list | awk '/keystone/ {print $2}')
keystone endpoint-create --service-id=$service --publicurl=http://$my_ip:5000/v2.0 --internalurl=http://$my_ip:5000/v2.0 --adminurl=http://$my_ip:35357/v2.0
# sh /root/config/keystone.sh
6.安装配置Glance

7.安装配置Nova
7.1.初始化Nova
(1).安装nova：
# yum -y install openstack-nova
(2).创建nova数据库：
# openstack-db --init --service nova
7.2.创建User，定义Services 和 API Endpoints
(1).编写脚本：
# vi /root/config/nova-user.sh
#!/bin/sh
my_ip=192.168.10.21
keystone user-create --name=nova --pass=service --email=nova@example.com
keystone user-role-add --user=nova --tenant=service --role=admin
keystone service-create --name=nova --type=compute --description="Nova Compute Service"
service=$(keystone service-list | awk '/nova/ {print $2}')
keystone endpoint-create --service-id=$service --publicurl=http://$my_ip:8774/v2/%\(tenant_id\)s --internalurl=http://$my_ip:8774/v2/%\(tenant_id\)s --adminurl=http://$my_ip:8774/v2/%\(tenant_id\)s
(2).运行脚本，创建用户、服务及api endpoint：
# sh /root/config/nova-user.sh
7.3.配置nova服务：
(1).修改/etc/nova.conf配置文件:
# vi /etc/nova/nova.conf
my_ip = 192.168.10.21
auth_strategy = keystone
state_path = /openstack/lib/nova
verbose=True
allow_resize_to_same_host = true
rpc_backend = nova.openstack.common.rpc.impl_qpid
qpid_hostname = 192.168.10.21
libvirt_type = kvm
glance_api_servers = 192.168.10.21:9292
novncproxy_base_url = http://192.168.10.21:6080/vnc_auto.html
vncserver_listen = $my_ip
vncserver_proxyclient_address = $my_ip
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
auth_host = 127.0.0.1
auth_port = 35357
auth_protocol = http
admin_user = nova
admin_tenant_name = service
admin_password = service
因上述配置文件中修改了instances实例存放的位置，还需要作一下操作：
修改instances路径，设置目录权限：
# cp -r /var/lib/nova/ /openstack/lib/
# chown -R nova:nova /openstack/lib/nova/
(2).配置libvirtd服务，删除virbr0
启动libvirt服务：
# service libvirtd start
查看net-list，发现default：
# virsh net-list
Name State Autostart Persistent
--------------------------------------------------
default active yes yes
删除default，即virbr0：
# virsh net-destroy default
Network default destroyed
# virsh net-undefine default
Network default has been undefined
重启libvirtd服务，设置开机自启动：
# service libvirtd restart
# chkconfig libvirtd on
(3).启动nova相关服务，设置开机自启动
# service messagebus start
# chkconfig messagebus on
启动nova服务，采用network网络服务：
# service openstack-nova-api start
# service openstack-nova-cert start

三、计算节点安装(Node01)
1.基础配置
操作系统使用CentOS-6.4-x86_64-minimal.iso，安装过程省略，本文采用yum源安装。
(1).导入第三方安装源
node01 ~]# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
node01 ~]# rpm -Uvh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
node01 ~]# yum install http://repos.fedorapeople.org/repos/openstack/openstack-havana/rdo-release-havana-7.noarch.rpm
(2).配置/etc/hosts文件
node01 ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.10.21 openstack
192.168.10.22 node01
(3).配置网络
node01 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO="static"
HWADDR="E4:1F:13:45:AB:C1"
ONBOOT="yes"
IPADDR=192.168.10.22
NETMASK=255.255.255.0
GATEWAY=192.168.10.1
TYPE="Ethernet"
# 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：
node01 ~]# 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
# setenforce 0
(5).修改/etc/sysctl.conf参数：
node01 ~]# vi /etc/sysctl.conf
……………………
net.ipv4.ip_forward = 1
……………………
#sysctl -p #使sysctl.conf配置生效
2.安装配置NTP客户端
(1).安装NTP客户端服务：
node01 ~]# yum -y install ntpdate
(2).设置时间同步：
node01 ~]# ntpdate 192.168.10.21
31 Mar 16:17:03 ntpdate: the NTP socket is in use, exiting
(3).设置计划任务：
node01 ~]# crontab -e
插入下行内容：
*/5 * * * * ntpdate 192.168.10.21 >> /var/log/ntpdate.log
3.设置环境变量
修改.bash_profile文件，添加以下参数：
node01 ~]# vi .bash_profile
………………
export OS_USERNAME=admin
export OS_TENANT_NAME=admin
export OS_PASSWORD=password
export OS_AUTH_URL=http://192.168.10.21:5000/v2.0
export SERVICE_ENDPOINT=http://192.168.10.21:35357/v2.0
export SERVICE_TOKEN=12dd70ede7c9d9d3ed3c
………………
执行下面的命令使变量即时生效：
node01 ~]# source .bash_profile
4.安装配置libvirt服务
(1).安装libvirt服务：
# yum -y install qemu-kvm libvirt
(2)启动libvirt服务：
node01 ~]# service libvirtd start
(3)查看net-list，发现default：
node01 ~]# virsh net-list
Name State Autostart Persistent
--------------------------------------------------
default active yes yes
(4)删除default，即virbr0：
node01 ~]# virsh net-destroy default
Network default destroyed
node01 ~]# virsh net-undefine default
Network default has been undefined
(5)重启libvirtd服务，设置开机自启动：
node01 ~]# service libvirtd restart
node01 ~]# chkconfig libvirtd on
5.安装MySQL客户端
(1).安装mysql客户端
# yum -y install mysql
(2).检查mysql数据库连通性
# mysql -h 192.168.10.21 -unova -pnova
Welcome to the MySQL monitor. ………………
mysql> quit;
Bye
6.安装配置Nova服务
(1)安装nova-compute、nova-network、nova-scheduler
# yum -y install openstack-nova-compute openstack-nova-network openstack-nova-scheduler
(2).修改nova配置文件
# vi /etc/nova/nova.conf
my_ip = 192.168.10.22
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 = 192.168.10.21
libvirt_type = kvm
glance_api_servers = 192.168.10.21:9292
novncproxy_base_url = http://192.168.10.21:6080/vnc_auto.html
vncserver_listen = 192.168.10.22
vncserver_proxyclient_address = 192.168.10.22
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
sql_connection=mysql://nova:nova@192.168.10.21/nova
auth_host = 192.168.10.21
auth_port = 35357
auth_protocol = http
admin_user = nova
admin_tenant_name = service
admin_password = service
因上管理节点nova.conf配置文件中修改了instances实例存放的位置，还需要作一下操作：
修改路径，设置目录权限：
# cp -r /var/lib/nova/ /openstack/lib/
# chown -R nova:nova /openstack/lib/nova/
(3).启动nova相关服务，设置开机自启动
# service messagebus start
# chkconfig messagebus on
# service openstack-nova-compute start
# service openstack-nova-network start
# chkconfig openstack-nova-compute on
# chkconfig openstack-nova-network on
*******************************************************************************************
OpenStack其他常用命令：
1.list nova服务，包含管理节点和计算节点
# nova service-list
