Ubuntu12.04 OpenStack Folsom 安装（VLAN模式）

Ubuntu12.04 OpenStack Folsom 安装（VLAN模式） – 陈沙克日志

Openstack Folsom 安装比较复杂，尤其是Quantum部分，新的内容很多。Quantum的租户网络有两种模式：GRE和VLAN模式，这两种方式配置有很大的区别，一个明显的区别就是控制节点，Vlan模式2块网卡，GRE模式需要3块网卡。

英文原文

我基本会参考原文做翻译，下面的和原文差异的地方

我的网络会会原文不同, 文档我会在真实的环境下验证，由于每个人的网络基本都是不一样，所以文档和IP相关的地方，我基本采用变量，比较灵活的方式，大家可以用sed命令实现修改。很多朋友安装不成功，基本都是因为更换IP，导致有地方没修改，所以提供sed的命令修改。
对原文提供的两个keystone导入数据的脚本做了细微的修改，主要是采用变量，让他更加灵活。
mysql直接采用IP访问，而不是localhost
keystone的token采用随机生成，而不是password

文档修改记录

2012年11月1日：copy以前的folsom的文档，专门针对vlan模式进行修改
2012年11月2日：基本把文档整理完，包括租户网络创建，vnc也已经可以工作。目前存在的问题是：metadata无法工作，密钥无法住人到虚拟机里，还有就是虚拟机网络还不能访问。

控制节点和计算节点需要2块网卡，计算节点需要支持虚拟化
全部的命令都是在root下运行

网络拓扑图

安装ubuntu 12.04.1 Server版本，最小化安装，只需要安装SSH server就可以。Cinder 需要一个单独的分区或者硬盘。

目前Folsom进入ubuntu 12.04的官方的源，不过需要你手工添加。源的官方说明

cat <<EOF >>/etc/apt/sources.list
deb  http://ubuntu-cloud.archive.canonical.com/ubuntu precise-proposed/folsom main
deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/folsom main
EOF

运行下面命令

apt-get install ubuntu-cloud-keyring
apt-get update && apt-get -y dist-upgrade

Hostname设置（可选）

# cat /etc/hostname 
controller

# cat /etc/hosts
127.0.0.1       localhost
10.1.199.58      controller.chenshake.com        controller
10.1.199.6      compute1.chenshake.com  compute1

# hostname
controller

# hostname -f
controller.chenshake.com

直接设置 /etc/network/interface

# cat /etc/network/interfaces 
# This file describes network interfaces avaiulable on your system
# and how to activate them. For more information, see interfaces(5).
# Modified by convert_static.sh.
auto lo

auto eth1
iface eth1 inet static
address 10.1.199.68
netmask 255.255.255.0

/etc/init.d/networking restart

设置IP转发

sed -i -r 's/^\s*#(net\.ipv4\.ip_forward=1.*)/\1/' /etc/sysctl.conf
echo 1 > /proc/sys/net/ipv4/ip_forward

检查修改结果

# sysctl -p
net.ipv4.ip_forward = 1

NTP服务器

编辑 /etc/ntp.conf ，在 server ntp.ubuntu.com 下添加两行

server ntp.ubuntu.com
server 127.127.1.0
fudge 127.127.1.0 stratum 10

或者直接运行下面命令

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

重启NTP服务

service ntp restart

cat >/root/novarc <<EOF
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=password
export MYSQL_PASS=password
export SERVICE_PASSWORD=password
export RABBIT_PASSWORD=password

export FLOATING_RANGE=$(/sbin/ifconfig eth0 | awk '/inet addr/ {print $2}' | cut -f2 -d ":" | awk -F "." '{print $1"."$2"."$3}').224/27
export OS_AUTH_URL="http://localhost:5000/v2.0/"
export SERVICE_ENDPOINT="http://localhost:35357/v2.0"
export SERVICE_TOKEN=$(openssl rand -hex 10)
export MASTER="$(/sbin/ifconfig eth0 | awk '/inet addr/ {print $2}' | cut -f2 -d ":")"
export LOCAL_IP="$(/sbin/ifconfig eth1 | awk '/inet addr/ {print $2}' | cut -f2 -d ":")"
EOF

你可以根据你的需要调整用户的密码。

source novarc
echo "source novarc">>.bashrc

Mysql

下面是我们需要用到的数据库

数据库用户密码 mysql root password nova nova password keystone keystone password glance glance password cinder cinder password quantum quantum password

设置自动安装，无需输入密码

cat <<MYSQL_PRESEED | debconf-set-selections
mysql-server-5.5 mysql-server/root_password password $MYSQL_PASS
mysql-server-5.5 mysql-server/root_password_again password $MYSQL_PASS
mysql-server-5.5 mysql-server/start_on_boot boolean true
MYSQL_PRESEED

安装mysql

apt-get -y install mysql-server python-mysqldb

运行远程访问mysql

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

service mysql restart

创建数据库

mysql -uroot -p$MYSQL_PASS <<EOF
CREATE DATABASE nova;
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '$MYSQL_PASS';
CREATE DATABASE glance;
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY '$MYSQL_PASS';

CREATE DATABASE quantum;
GRANT ALL PRIVILEGES ON quantum.* TO 'quantum'@'%'IDENTIFIED BY '$MYSQL_PASS';
FLUSH PRIVILEGES;
EOF

RabbitMQ

apt-get -y install rabbitmq-server

修改默认密码

我们把默认密码 guest，改成password

rabbitmqctl change_password guest $RABBIT_PASSWORD

Keystone

apt-get -y install keystone python-keystone python-keystoneclient

编辑 /etc/keystone/keystone.conf

[DEFAULT]
admin_token = d111cf2d97251a9e0422

log_config = /etc/keystone/logging.conf
[sql]
connection = mysql://keystone:[email protected]:3306/keystone
idle_timeout = 200

或者直接运行下面脚本

sed -i -e " s/# admin_token = ADMIN/admin_token = $SERVICE_TOKEN/g; s/# bind_host = 0.0.0.0/bind_host = 0.0.0.0/g; s/# public_port = 5000/public_port = 5000/g; s/# admin_port = 35357/admin_port = 35357/g; s/# compute_port = 8774/compute_port = 8774/g; s/# verbose = True/verbose = True/g; s/# idle_timeout/idle_timeout/g" /etc/keystone/keystone.conf

使用mysql数据库

sed -i '/connection = .*/{s|sqlite:///.*|mysql://'"keystone"':'"$MYSQL_PASS"'@'"$MASTER"'/keystone|g}' /etc/keystone/keystone.conf

重启服务和初始化数据库

service keystone restart
keystone-manage db_sync

导入keystone数据

keystone-data.sh

wget http://www.chenshake.com/wp-content/uploads/2012/09/keystone-data.sh_.txt

mv keystone-endpoints.sh_.txt keystone-endpoints.sh
bash keystone-endpoints.sh

Glance

apt-get -y install glance glance-api python-glanceclient glance-common

编辑/etc/glance/glance-api.conf 和 /etc/glance/glance-registry.conf ,两个文件，都是修改4个地方

sql_connection = mysql://glance:[email protected]/glance
admin_tenant_name = service
admin_user = glance
admin_password = password

或者直接运行下面脚本实现

sed -i -e " s/%SERVICE_TENANT_NAME%/service/g; s/%SERVICE_USER%/glance/g; s/%SERVICE_PASSWORD%/$SERVICE_PASSWORD/g; " /etc/glance/glance-api.conf /etc/glance/glance-registry.conf

编辑 /etc/glance/glance-api.conf

#notifier_strategy = noop
notifier_strategy = rabbit

#rabbit_password = guest
rabbit_password = password

运行下面命令进行修改

sed -i " s/notifier_strategy = noop/notifier_strategy = rabbit/g;s/rabbit_password = guest/rabbit_password = $RABBIT_PASSWORD/g;" /etc/glance/glance-api.conf

运行下面命令

这是一个大工程，目前还没办法用脚本来实现，也就只能step by step。不过这个过程，倒是可以帮助你深入了解一下quantum。下面的步骤，大家需要小心就可以。我验证过一次。

查看member roles ID

keystone role-list

查看service 租户的ID

keystone tenant-list

创建一个租户

keystone tenant-create --name project_one

创建一个用户：user_one，roles是成员角色

keystone user-create --name=user_one --pass=user_one --tenant-id $put_id_of_project_one [email protected]
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

为该租户创建一个网络

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

为租户创建一个子网

quantum subnet-create --tenant-id $put_id_of_project_one net_proj_one 10.10.10.0/24

为租户创建一个路由

quantum router-create --tenant_id $put_id_of_project_one router_proj_one

路由和网络进行关联

quantum router-interface-add $put_router_proj_one_id_here $put_subnet_id_here

创建外部网络（service 租户的ID，通过 keystone tenant-list 查看）
