主机分配:

主 机名         IP(Static)     系统              角色

openstack      192.168.0.210    CentOS x64     管理节点/计算节点

node01         192.168.0.212    CentOS x64        计算节点


二 管理节点安装 ( Openstack )


首先更新系统版本 yum update ( 否则 报yum ssl错误 )


reboot 

 

2.1 (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 -y install http://repos.fedorapeople.org/repos/openstack/openstack-havana/rdo-release-havana-7.noarch.rpm



2.2  (配置/hetc/hosts 文件)

vi /etc/hosts

192.168.0.211 openstack

192.168.0.212 node01


2.3  (配置网络)



2.4  关闭selinux

sed -i ‘/SELINUX/s/enforcing/disabled/‘ /etc/selinux/config

setenforce 0



2.5  修改/etc/sysctl.conf参数

vi /etc/sysctl.conf


修改

net.ipv4.ip_forward = 1

sysctl -p


2.6  安装ntp服务

yum -y install ntp


service ntpd start

chkconfig ntpd on


2.7  安装MySQL服务

yum -y install mysql mysql-server MySQL-python


vi /etc/my.cnf


[mysqld]在后面增加

bind-address = 0.0.0.0


启动mysqld 并设置自动启动 

service mysqld start

chkconfig mysqld on


修改MySQL密码为jicki

mysqladmin -uroot password ‘jicki‘; history -c



2.8  安装qpid 服务

yum -y install qpid-cpp-server memcached


修改/etc/qpidd.conf配置文件,将auth设置为no

vi /etc/qpidd.conf

auth=no



启动 qpidd 以及 设置自定启动

service qpidd start

chkconfig qpidd on



安装OpenStack工具包

yum -y install openstack-utils



2.9  安装配置KeyStone

安装KeyStone服务

yum -y install openstack-keystone



创建keystone数据库,修改配置文件中的数据库链接

openstack-db --init --service keystone



修改配置文件中的数据库链接  ( 帐号密码都为上面创建的 keystone )

openstack-config --set /etc/keystone/keystone.conf sql connection mysql://keystone:keystone@localhost/keystone



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)

export SERVICE_ENDPOINT=http://127.0.0.1:35357/v2.0

mkdir /root/config                (创建配置文件目录 用于记录一些key)

echo $SERVICE_TOKEN > /root/config/ks_admin_token.txt

cat /root/config/ks_admin_token.txt

35fbb7e5601644a1f37f

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。


openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_token $SERVICE_TOKEN



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



启动keystone服务,设置开机自启动

service openstack-keystone start

chkconfig openstack-keystone on



2.10  定义Users、Tenants and Roles


修改.bash_profile文件,添加以下参数

vi /root/.bash_profile


export OS_USERNAME=admin

export OS_TENANT_NAME=admin

export OS_PASSWORD=jicki

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=35fbb7e5601644a1f37f


使变量即时生效

source .bash_profile



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‘



创建一个管理员用户admin

keystone user-create --name=admin --pass=jicki --email=keystone@localhost



创建一个管理员角色admin

keystone role-create --name=admin



将角色添加到用户

keystone user-role-add --user=admin --tenant=admin --role=admin



2.11  定义Services 和 API Endpoints

为KeyStone创建一个服务

keystone service-create --name=keystone --type=identity --description="KeystoneIdentity Service"



使用服务ID创建一个endpoint

vi /root/config/keystone.sh


#!/bin/bash

my_ip=192.168.0.211

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



2.12  安装配置Glance

yum -y install openstack-glance



创建Glance数据库

openstack-db --init --service glance



修改配置文件中的数据库链接

openstack-config --set /etc/glance/glance-api.conf DEFAULT sql_connection mysql://glance:glance@localhost/glance

openstack-config --set /etc/glance/glance-registry.conf DEFAULT sql_connection mysql://glance:glance@localhost/glance



2.13  创建User,定义Services 和 API Endpoints

为Glance服务创建一个glance用户

keystone user-create --name=glance --pass=service --email=glance@localhost

keystone user-role-add --user=glance --tenant=service --role=admin



为glance创建一个服务

keystone service-create --name=glance --type=image --description="Glance ImageService"



使用服务ID创建一个endpoint


vi /root/config/glance.sh


#!/bin/bash

my_ip=192.168.0.211

service=$(keystone service-list | awk ‘/glance/ {print $2}‘)

keystone endpoint-create --service-id=$service --publicurl=http://$my_ip:9292 --internalurl=http://$my_ip:9292 --adminurl=http://$my_ip:9292


sh /root/config/glance.sh



配置Glance服务

将keystone认证信息添加到glance配置文件中


openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_host 127.0.0.1

openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_port 35357

openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_protocol http

openstack-config --set /etc/glance/glance-api.conf keystone_authtoken admin_tenant_name service

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken admin_user glance

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken admin_password service
