作者：罗丝012 | 来源：互联网 | 2014-05-27 20:14

本文为半年前的文档，是在https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/master/OpenStack_Folsom_Install_Guide_WebVersion.rst的基础上，通过自己做的实验的修改版本，搭建好之后虚拟机无法

visudo /etc/sudoers

添加：

#Modifythe quantum user

quantumALL=NOPASSWD: ALL

还没有在Folsom版本中做过实验，有Folsom的可以试一试。

2. Getting Ready

2.1. Preparing Ubuntu 12.10

· After you install Ubuntu 12.10 Server 64bits, Go to thesudo mode and don't leave it until the end of this guide:

sudo su

· Update your system:

apt-get update

apt-get upgrade

apt-get dist-upgrade

2.2.Networking

· Only one NIC on the controller node need internet access:

vim/etc/network/interfaces

auto lo

iface lo inet loopback

# The primary network interface

auto p51p1

iface p51p1 inet static

address 10.10.10.14

netmask 255.255.255.0

network 10.10.10.0

broadcast 10.10.10.255

gateway 10.10.10.1

# dns-* options are implemented by the resolvconf package, if installed

dns-nameservers 8.8.8.8

dns-search ourfuture.cn

auto p51p2

iface p51p2 inet static

address 192.168.31.14

netmask 255.255.255.0

/etc/init.d/networking restart

2.3. MySQL &RabbitMQ

· Install MySQL:

apt-get install mysql-server python-mysqldb

· Configure mysql to accept all incoming requests:

sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mysql/my.cnf

service mysql restart

让mysql支持外部访问：

命令：

mysql -uroot -ppassword

grant all privileges on *.* to root@"%"identified by "password" with grant option;

FLUSH PRIVILEGES;

删除空用户：

命令：

use mysql;

delete from user where user="";

quit;

重启服务：

命令：

service mysql restart

· Install RabbitMQ:

apt-get install rabbitmq-server

2.4. Node synchronization

· Install other services:

apt-get install ntp

· Configure the NTP server to synchronize between yourcompute nodes and the controller node:

sed -i 's/server ntp.ubuntu.com/serverntp.ubuntu.com\nserver 127.127.1.0\nfudge 127.127.1.0 stratum 10/g'/etc/ntp.conf

service ntp restart

2.5. Others

· Install other services:

apt-get install vlan bridge-utils

· Enable IP_Forwarding:

vim /etc/sysctl.conf

# Uncomment net.ipv4.ip_forward=1, to save you fromrebooting, do this:

sysctl net.ipv4.ip_forward=1

2.6. Keystone

· Start by the keystone packages:

apt-get install keystone

· Create a new MySQL database for keystone:

mysql -uroot -ppassword

CREATE DATABASE keystone;

GRANT ALL ON keystone.* TO 'keystoneUser'@'%' IDENTIFIEDBY 'keystonePass';

quit;

· Adapt the connection attribute in the/etc/keystone/keystone.conf to the new database:

vim /etc/keystone/keystone.conf

connection = mysql://keystoneUser:keystonePass@192.168.31.14/keystone

· Restart the identity service then synchronize thedatabase:

service keystone restart

keystone-manage db_sync

· Fill up the keystone database using the two scriptsavailable in the Scriptsfolder of this git repository. Beware that you MUSTcomment every part related to Quantum if you don't intend to install itotherwise you will have trouble with your dashboard later:

#Modify the HOST_IP and EXT_HOST_IP variables beforeexecuting the scripts

chmod +x keystone_basic.sh

chmod +x keystone_endpoints_basic.sh

./keystone_basic.sh

./keystone_endpoints_basic.sh

· Create a simple credential file and load it so you won'tbe bothered later:

nano creds

#Paste the following:

export OS_TENANT_NAME=admin

export OS_USERNAME=admin

export OS_PASSWORD=admin_pass

export OS_AUTH_URL="http://10.10.10.14:5000/v2.0/"

# Load it:

source creds

· To test Keystone, we use a simple curl request:

apt-get install curl openssl

curl http:// 10.10.10.14:35357/v2.0/endpoints -H'x-auth-token: ADMIN'

2.7. Glance

· After installing Keystone, we continue with installingimage storage service a.k.a Glance:

apt-get install glance

· Create a new MySQL database for Glance:

mysql -uroot -ppassword

CREATE DATABASE glance;

GRANT ALL ON glance.* TO 'glanceUser'@'%' IDENTIFIED BY'glancePass';

quit;

· Update /etc/glance/glance-api-paste.ini with:

vim /etc/glance/glance-api-paste.ini

[filter:authtoken]

paste.filter_factory =keystone.middleware.auth_token:filter_factory

· Restart the glance-api and glance-registry services:

service glance-api restart; service glance-registryrestart

· Synchronize the glance database:

glance-manage db_sync

· Restart the services again to take into account the newmodifications:

service glance-registry restart; service glance-apirestart

· To test Glance's well installation, we upload a new imageto the store. Start by downloading the cirros cloud image to your node and thenuploading it to Glance:

· mkdir images

· cd images

· wgethttps://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img

5. Your First VM

To start yourfirst VM, we first need to create a new tenant, user, internal and externalnetwork. SSH to your controller node and perform the following.

· Create a new tenant

keystone tenant-create --name project_one

keystone user-create --name=user_one --pass=user_one--tenant-id $put_id_of_project_one --email=user_one@domain.com

root@node15:/etc/init.d# keystone role-list

keystone user-role-add --tenant-id $put_id_of_project_one --user-id $put_id_of_user_one --role-id$put_id_of_member_role

· Create a new network for the tenant:

quantum net-create --tenant-id $put_id_of_project_onenet_proj_one --provider:network_type vlan --provider:physical_network physnet1--provider:segmentation_id 1024

quantum subnet-create --tenant-id $put_id_of_project_one net_proj_one50.50.1.0/24

quantum router-create --tenant-id $put_id_of_project_onerouter_proj_one

quantum router-interface-add $put_router_proj_one_id_here$put_subnet_id_here

· Create your external network with the tenant id belongingto the service tenant (keystone tenant-list to get the appropriate id)

quantum net-create --tenant-id $put_id_of_service_tenantext_net --router:external=True

root@node55:~# keystone tenant-list

quantum subnet-create --tenant-id$put_id_of_service_tenant --allocation-pool start=10.10.10.102,end=10.10.10.126--gateway 10.10.10.1 ext_net 10.10.10.100/24 --enable_dhcp=False

quantum router-gateway-set $put_router_proj_one_id_here$put_id_of_ext_net_here

VMs gain accessto the metadata server locally present in the controller node via the externalnetwork. To create that necessary connection perform the following:

· Get the IP address of router proj one:

quantum port-list -- --device_id --device_owner network:router_gateway

route add -net 50.50.1.0/24 gw $router_proj_one_IP

Unfortunatly,you can't use the dashboard to assign floating IPs to VMs so you need to getyour hands a bit dirty to give your VM a public IP.

· Start by allocating a floating ip to the project onetenant:

quantum floatingip-create --tenant-id $put_id_of_project_oneext_net

quantum port-list

· Associate the floating IP to your VM:

quantum floatingip-associate $put_id_floating_ip$put_id_vm_port

This is it!, You can nowping you VM and start administrating you OpenStack !
