OpenStack Grizzly详细安装指导
一、环境介绍：控制节点eth0 (10.10.10.51), eth1 (192.168.100.51)网络节点eth0 (10.10.10.52), eth1 (10.20.20.52), eth2 (192.168.100.52)计算节点eth0 (10.10.10.53), eth1 (10.20.20.53)
说明1: 使用 dpkg -s <packagename> to 确保 grizzly packages (version : 2013.1)
说明2: 你可以添加比较多的计算节点，下面是网络结构
二、控制节点
2.1. Ubuntu准备
安装64位 Ubuntu 12.04 或则13.04 Server ，切换sudo模式
[*]sudo su
复制代码
添加 Grizzly 源 :
[*]apt-get install -y ubuntu-cloud-keyring
[*]echo deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/grizzly main >> /etc/apt/sources.list.d/grizzly.list
复制代码 对于上面命令不了解，可参考
安装openstack过程中：如何添加源，echo，<<分别代表什么意思？
更新系统:
[*]apt-get update -y
[*]apt-get upgrade -y
[*]apt-get dist-upgrade -y
复制代码
2.2. 网络配置
只有一个网卡接入互联网
[*]#For Exposing OpenStack API over the internet
[*]auto eth1
[*]iface eth1 inet static
[*]address 192.168.100.51
[*]netmask 255.255.255.0
[*]gateway 192.168.100.1
[*]dns-nameservers 8.8.8.8
[*]
[*]#Not internet connected(used for OpenStack management)
[*]auto eth0
[*]iface eth0 inet static
[*]address 10.10.10.51
[*]netmask 255.255.255.0
复制代码
重新启动网络
[*]service networking restart
复制代码
2.3. MySQL & RabbitMQ安装
安装 MySQL:
[*]apt-get install -y mysql-server python-mysqldb
[*]
复制代码
出现这个界面是输入MySQL的密码
配置mysql
[*]sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mysql/my.cnf
[*]service mysql restart
复制代码 对于上面命令不了解可以参考下面内容：

2.4. RabbitMQ
安装 RabbitMQ:
[*]apt-get install -y rabbitmq-server
[*]
复制代码
安装 NTP service:
[*]apt-get install -y ntp
[*]
复制代码
创建数据库:
[*]mysql -u root -p
[*]
[*]#Keystone
[*]CREATE DATABASE keystone;
[*]GRANT ALL ON keystone.* TO 'keystoneUser'@'%' IDENTIFIED BY 'keystonePass';
[*]
[*]#Glance
[*]CREATE DATABASE glance;
[*]GRANT ALL ON glance.* TO 'glanceUser'@'%' IDENTIFIED BY 'glancePass';
[*]
[*]#Quantum
[*]CREATE DATABASE quantum;
[*]GRANT ALL ON quantum.* TO 'quantumUser'@'%' IDENTIFIED BY 'quantumPass';
[*]
[*]#Nova
[*]CREATE DATABASE nova;
[*]GRANT ALL ON nova.* TO 'novaUser'@'%' IDENTIFIED BY 'novaPass';
[*]
[*]#Cinder
[*]CREATE DATABASE cinder;
[*]GRANT ALL ON cinder.* TO 'cinderUser'@'%' IDENTIFIED BY 'cinderPass';
[*]
[*]quit;
复制代码 对于上面命令不了解可以参考下面内容：

2.5. 其他
安装其它服务:
[*]apt-get install -y vlan bridge-utils
复制代码
启动 IP_Forwarding:
[*]sed -i 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf
[*]
[*]# To save you from rebooting, perform the following
[*]sysctl net.ipv4.ip_forward=1
复制代码
2.6. Keystone
安装Keystone
[*]apt-get install -y keystone
复制代码
在文件 /etc/keystone/keystone.conf中添加如下语句
[*]connection = mysql://keystoneUser:keystonePass@10.10.10.51/keystone
复制代码 上面的配置可能大家的理解不一样这里给出图示：
上面connection注释掉，替换为上面链接如下图所示
重新启动Keystone，同步数据库
[*]service keystone restart
[*]keystone-manage db_sync
复制代码
下载keystone_basic.sh，keystone_endpoints_basic.sh并执行脚本
[*]#Modify the **HOST_IP** and **EXT_HOST_IP** variables before executing the scripts
[*]
[*]wget https://raw.github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/OVS_MultiNode/KeystoneScripts/keystone_basic.sh
[*]wget https://raw.github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/OVS_MultiNode/KeystoneScripts/keystone_endpoints_basic.sh
[*]
[*]chmod +x keystone_basic.sh
[*]chmod +x keystone_endpoints_basic.sh
[*]
[*]./keystone_basic.sh
[*]./keystone_endpoints_basic.sh
复制代码
注释与说明：
查看脚本keystone_basic.sh内容：
上面ip为控制节点的ip
查看脚本keystone_endpoints_basic.sh内容：
上面HOST_IP分别为控制节点的eth0,eth1两个网卡ip。
当脚本./keystone_basic.sh执行时，没有任何输出说明脚本执行成功。
执行./keystone_endpoints_basic.sh脚本时，会看到如下输出：
创建证书，后面不会遇到麻烦：（其实这里是环境变量的配置，我们在后面的操作中，就不需要每次都输入用户名密码等）
[*]nano creds
[*]
[*]#Paste the following:
[*]export OS_TENANT_NAME=admin
[*]export OS_USERNAME=admin
[*]export OS_PASSWORD=admin_pass
[*]export OS_AUTH_URL="http://192.168.100.51:5000/v2.0/"
[*]
[*]# Load it:
[*]source creds
复制代码
使用CLI命令，测试使用安装成功
[*]keystone user-list
复制代码
2.7. Glance
安装Glance
[*]apt-get install -y glance
复制代码 更新/etc/glance/glance-api-paste.ini 文件
[*]
[*]paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
[*]delay_auth_decision = true
[*]auth_host = 10.10.10.51
[*]auth_port = 35357
[*]auth_protocol = http
[*]admin_tenant_name = service
[*]admin_user = glance
[*]admin_password = service_pass
复制代码
注释与说明：
即使找到上面，然后把相关内容进行粘帖。
替换为如下：
更新 /etc/glance/glance-registry-paste.ini文件
[*]
[*]paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
[*]auth_host = 10.10.10.51
[*]auth_port = 35357
[*]auth_protocol = http
[*]admin_tenant_name = service
[*]admin_user = glance
[*]admin_password = service_pass
复制代码
[*]
[*]flavor = keystone
复制代码
操作同上，也是内容的替换。
替换/etc/glance/glance-api.conf文件
[*]sql_connection = mysql://glanceUser:glancePass@10.10.10.51/glance
复制代码
注释与说明：
同样是将原先sql_connection注释掉，替换为sql_connection = mysql://glanceUser:glancePass@10.10.10.51/glance
更新 /etc/glance/glance-registry.conf：
[*]sql_connection = mysql://glanceUser:glancePass@10.10.10.51/glance
复制代码
[*]
[*]flavor = keystone
复制代码
到这里我们是否找到一个规律就是无论是替换还是新增加内容，我们只要找到相关标签即可。如果有内容即替换，无内容则添加。
重启glance-api 与 glance-registry services:
[*]service glance-api restart; service glance-registry restart
复制代码
同步 glance 数据库:
[*]glance-manage db_sync
复制代码
导入img
[*]glance image-create --name myFirstImage --is-public true --container-format bare --disk-format qcow2 --location http://download.cirros-cloud.net/0.3.1/cirros-0.3.1-x86_64-disk.img

安装 Quantum openvswitch 代理:
[*]apt-get -y install quantum-plugin-openvswitch-agent
复制代码 编辑 the OVS plugin配置文件 /etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini:
[*]#Under the database section
[*]
[*]sql_connection = mysql://quantumUser:quantumPass@10.10.10.51/quantum
[*]
[*]#Under the OVS section
[*]
[*]tenant_network_type = gre
[*]tunnel_id_ranges = 1:1000
[*]integration_bridge = br-int
[*]tunnel_bridge = br-tun
[*]local_ip = 10.20.20.53
[*]enable_tunneling = True
[*]
[*]#Firewall driver for realizing quantum security group function
[*]
[*]firewall_driver = quantum.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
复制代码 注释与说明：
注意上面的文件不能一次性全部复制到文件中，需要找到相应的标签，如下图所示为ovs的配置
确保你的 rabbitMQ IP在 /etc/quantum/quantum.conf文件中配置指向控制节点:
[*]rabbit_host = 10.10.10.51
[*]
[*]#And update the keystone_authtoken section
[*]
[*]
[*]auth_host = 10.10.10.51
[*]auth_port = 35357
[*]auth_protocol = http
[*]admin_tenant_name = service
[*]admin_user = quantum
[*]admin_password = service_pass
[*]signing_dir = /var/lib/quantum/keystone-signing
复制代码 注释与说明：
同理上面的内容也是相应的内容放到相应的标签下面。切忌全部复制。
重启服务:
[*]service quantum-plugin-openvswitch-agent restart
复制代码
4.6. Nova
安装nova所需要组件:
[*]apt-get install -y nova-compute-kvm
[*]
复制代码
修改文件/etc/nova/api-paste.ini authtoken 部分
[*]
[*]paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
[*]auth_host = 10.10.10.51
[*]auth_port = 35357
[*]auth_protocol = http
[*]admin_tenant_name = service
[*]admin_user = nova
[*]admin_password = service_pass
[*]signing_dirname = /tmp/keystone-signing-nova
[*]# Workaround for https://bugs.launchpad.net/nova/+bug/1154809
[*]auth_version = v2.0
复制代码
编辑文件 /etc/nova/nova-compute.conf
[*]
[*]libvirt_type=kvm
[*]libvirt_ovs_bridge=br-int
[*]libvirt_vif_type=ethernet
[*]libvirt_vif_driver=nova.virt.libvirt.vif.LibvirtHybridOVSBridgeDriver
[*]libvirt_use_virtio_for_bridges=True
