主机名 IP（Static） 系统 配置 角色
openstack 192.168.20.200 CentOS-6.4-x86_64-minimal 4CPU,16G,300G,2网卡 管理节点/计算节点
node01 192.168.20.201 CentOS-6.4-x86_64-minimal 4CPU,16G,300G,2网卡 计算节点
初始化配置：
(1).配置/etc/hosts文件
[root@openstack ~]# 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
(2).配置网络
[root@openstack ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.20.200
NETMASK=255.255.255.0
GATEWAY=192.168.20.2
[root@openstack ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
(3).关闭selinux：
[root@openstack ~]# vi /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@openstack ~]# setenforce 0
(4).修改/etc/sysctl.conf参数：
[root@openstack ~]# vi /etc/sysctl.conf
……………………
net.ipv4.ip_forward=1
net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0
……………………
[root@openstack ~]#sysctl -p #使sysctl.conf配置生效
(5).关闭多余的服务(可选)：
#!/bin/bash
SERVICE_SUM="auditd blk-availability iscsi iscsid lvm2-monitor mdmonitor multipathd netconsole postfix rdisc restorecond saslauthd"
echo $SERVICE_SUM | xargs -n1 | while read SERVICE
do
chkconfig $SERVICE off
service $SERVICE stop
done
(6).导入第三方安装源：
[root@openstack ~]# yum -y install http://repos.fedorapeople.org/repos/openstack/openstack-icehouse/rdo-release-icehouse-3.noarch.rpm
[root@openstack ~]# yum -y install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
(7).更新kernel：
[root@openstack ~]# yum -y install kernel-2.6.32-358.123.2.openstack*
(8).安装OpenStack工具包：
[root@openstack ~]# yum -y install openstack-utils openstack-selinux
(9).重启：
[root@openstack ~]# reboot
2.安装配置NTP服务
(1).安装NTP服务：
[root@openstack ~]# yum -y install ntp
(2).配置NTP服务：
[root@openstack ~]# 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：
[root@openstack ~]# service ntpd start
[root@openstack ~]# chkconfig ntpd on
3.配置安装MySQL：
(1).安装MySQL服务：
[root@openstack ~]# yum -y install mysql mysql-server MySQL-python
（yum install mysql MySQL-python in node）
(2).修改MySQL配置文件：
[mysqld]
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
default-storage-engine = innodb
collation-server = utf8_general_ci
init-connect = 'SET NAMES utf8'
character-set-server = utf8
[mysqld_safe]
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：
[root@openstack ~]# service mysqld start
[root@openstack ~]# chkconfig mysqld on
(4).修改MySQL密码为passwd：
[root@openstack ~]# mysqladmin -uroot password 'passwd'; history -c
4.安装配置qpid服务
(1).安装qpid服务：
[root@openstack ~]# yum -y install qpid-cpp-server memcached
(2).修改/etc/qpidd.conf配置文件,将auth设置为no：
[root@openstack ~]# vi /etc/qpidd.conf
……………………
auth=no
(3).启动qpid服务，设置开机启动：
[root@openstack ~]# service qpidd start
[root@openstack ~]# chkconfig qpidd on
5.安装配置KeyStone
(1).安装KeyStone服务：
[root@openstack ~]# yum -y install openstack-keystone python-keystoneclient
(2).创建keystone数据库，修改配置文件中的数据库链接：
[root@openstack ~]# openstack-db --init --service keystone --rootpw passwd
(3).修改配置文件中的数据库链接：
[root@openstack ~]# 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：
[root@openstack ~]# export SERVICE_TOKEN=$(openssl rand -hex 10) //随机生成SERVICE_TOKEN值，请牢记
[root@openstack ~]# export SERVICE_ENDPOINT=http://127.0.0.1:35357/v2.0
[root@openstack ~]# mkdir /root/config
[root@openstack ~]# echo $SERVICE_TOKEN > /root/config/ks_admin_token.txt
[root@openstack ~]# cat /root/config/ks_admin_token.txt
12dd70ede7c9d9d3ed3c
[root@openstack ~]# 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：
[root@openstack ~]# keystone-manage pki_setup --keystone-user keystone --keystone-group keystone
[root@openstack ~]# chown -R keystone:keystone /etc/keystone/* /var/log/keystone/keystone.log
(6).启动keystone服务，设置开机自启动：
[root@openstack ~]# service openstack-keystone start
[root@openstack ~]# chkconfig openstack-keystone on
[root@openstack ~]# (crontab -l 2>&1 | grep -q token_flush) || echo '@hourly /usr/bin/keystone-manage token_flush >/var/log/keystone/keystone-tokenflush.log 2>&1' >> /var/spool/cron/root
5.2.定义Users、Tenants and Roles
(1).修改.bash_profile文件，添加以下参数：
[root@openstack ~]# vi .bash_profile
………………
export OS_USERNAME=admin
export OS_PASSWORD=password
export OS_TENANT_NAME=admin
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：
[root@openstack ~]# source .bash_profile
(2).创建一个管理员用户admin：
[root@openstack ~]# keystone user-create --name=admin --pass=password --email=keystone@chensh.net

[root@openstack ~]# keystone user-role-add --user=admin --tenant=admin --role=admin
WARNING: Bypassing authentication using a token & endpoint (authentication credentials are being ignored).

[root@openstack ~]# openstack-config --set /etc/glance/glance-registry-paste.ini filter:authtoken admin_password service
(3).修改镜像文件的存放路径（默认存放在/var/lib/glance目录下，若不需修改，此步骤可省略）
[root@openstack ~]# openstack-config --set /etc/glance/glance-api.conf DEFAULT filesystem_store_datadir /openstack/glance/images/
[root@openstack ~]# openstack-config --set /etc/glance/glance-api.conf DEFAULT scrubber_datadir /openstack/glance/scrubber
[root@openstack ~]# openstack-config --set /etc/glance/glance-api.conf DEFAULT image_cache_dir /openstack/glance/image-cache/
[root@openstack ~]# mkdir /openstack
[root@openstack ~]# cp -a /var/lib/glance/ /openstack/
[root@openstack ~]# chown -R glance:glance /openstack/glance/
(4).启动glance服务，设置开机自启动
[root@openstack ~]# service openstack-glance-api start
[root@openstack ~]# service openstack-glance-registry start
[root@openstack ~]# chkconfig openstack-glance-api on
[root@openstack ~]# chkconfig openstack-glance-registry on
6.4.Glance测试
