Ubuntu13.04安装Grizzly版OpenStack

1. 计划

Control Node NetworkNode eth0 (10.0.0.2), eth1 (192.168.1.232) eth0 (10.0.0.3), eth1 (192.168.1.233) Compute Node eth0 (10.0.0.4), eth1 (192.168.1.234)

1.Control Node

1.1前期准备

1.1.1 Ubuntu系统准备

切换用户

sudosu 增加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 升级系统：

apt-get update apt-get upgrade apt-getdist-upgrade 1.1.2网络设置

编辑/etc/network/interfaces

#For Exposing OpenStack API over the internet auto eth0 iface eth0inet static address192.168.1.232 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 8.8.8.8 #Not internet connected(used for OpenStack management) auto eth1 iface eth1inet static address10.0.0.2 netmask 255.255.255.0 设置好后重启网络：service networking restart

Ubuntu13.04桌面版不要用上面的命令重启网络，不然会卡死！

可以用ifdown和ifup来启动和停止网卡

1.1.3安装MySQL &RabbitMQ

安装MySQL：

apt-get install -y mysql-server python-mysqldb 配置并重启MySQL：

sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mysql/my.cnf servicemysql restart 创建表：

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; 安装RabbitMQ：

apt-get install -y rabbitmq-server 安装NTP：

apt-get install -y ntp 配置NTP：

#Comment the ubuntu NTP servers sed -i 's/server 0.ubuntu.pool.ntp.org/#server 0.ubuntu.pool.ntp.org/g' /etc/ntp.conf sed -i 's/server 1.ubuntu.pool.ntp.org/#server 1.ubuntu.pool.ntp.org/g' /etc/ntp.conf sed -i 's/server 2.ubuntu.pool.ntp.org/#server 2.ubuntu.pool.ntp.org/g' /etc/ntp.conf sed -i 's/server 3.ubuntu.pool.ntp.org/#server 3.ubuntu.pool.ntp.org/g' /etc/ntp.conf #Set the network node to follow up your conroller node sed -i 's/server ntp.ubuntu.com/server 10.0.0.2/g' /etc/ntp.conf servicentp restart 1.1.4其他

apt-get install -y vlan bridge-utils 配置/etc/sysctl.conf

sed -i 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf 1.2 Keystone

安装并检查状态：

apt-get install -y keystone service keystone status 修改/etc/keystone/keystone.conf中的数据库连接

connection = mysql://keystoneUser:keystonePass@10.0.0.2/keystone 重启并同步数据库：

service keystone restart keystone-manage db_sync 用下面两个脚本去填充keystone数据库，也就是增加user，tenant，role和service以及service的endpoint

#Modify the HOST_IP and HOST_IP_EXT variables before executing the scripts wget https://raw.github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/OVS_SingleNode/KeystoneScripts/keystone_basic.sh wget https://raw.github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/OVS_SingleNode/KeystoneScripts/keystone_endpoints_basic.sh chmod +x keystone_basic.sh chmod +x keystone_endpoints_basic.sh ./keystone_basic.sh ./keystone_endpoints_basic.sh 修改keystone_basic.sh中的HOST_IP为自己的Eth0的IP，ADMIN_PASSWORD和SERVICE_PASSWORD可改可不改：

修改keystone_endpoints_basic.sh中的HOST_IP和EXT_HOST_IP，同时将连接keystone数据库的的用户名和密码进行修改：

编辑文件creds

#Paste the following: export OS_TENANT_NAME=admin export OS_USERNAME=admin export OS_PASSWORD=admin_pass export OS_AUTH_URL=\"http://192.168.1.232:5000/v2.0/\" 引入环境变量中： sourcecreds

或者可以直接加入root（cat creds>> /root/.bashrc）的环境变量，这样重启后就无需再次引入了

查看创建的user

keystone user-list 同样有命令 keystone tenant-list 和 keystone role-list

1.3 Glance

安装并查看状态：

apt-get install -y glance service glance-api status service glance-registry status 修改/etc/glance/glance-api-paste.ini

和/etc/glance/glance-registry-paste.ini文件

注：红色为必须要修改（核对）的地方，建议把提到的这几项都核对一下：

[filter:authtoken] paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory delay_auth_decision = true auth_host = 10.0.0.2 auth_port = 35357 auth_protocol = http admin_tenant_name = service admin_user = glance admin_password = service_pass 编辑/etc/glance/glance-api.conf和/etc/glance/glance-registry.conf，修改数据库连接：

sql_connection = mysql://glanceUser:glancePass@10.0.0.2/glance 并且在[paste_deploy]下加上flavor = keystone

[paste_deploy] flavor = keystone 重启服务

service glance-api restart; service glance-registry restart 同步数据库：

glance-manage db_sync 再次重启服务

service glance-registry restart; service glance-api restart 上传镜像测试glance的安装情况：

安装horizon

apt-get install openstack-dashboard memcached 如果不喜欢OpenStackubuntu的主题页面,可以去除改包：

dpkg --purge openstack-dashboard-ubuntu-theme 重启apache2 和memcached服务

service apache2 restart; service memcached restart 然后就可以从网页上访问192.168.1.232/horizon 如果没有改，则默认的账号和密码是： admin:admin_pass.

#br-int will be used for VM integration ovs-vsctl add-brbr-int #br-ex is used to make to VM accessible from the internet ovs-vsctl add-brbr-ex 2.3 Quantum

安装 Quantum 代理组件:

apt-get -y install quantum-plugin-openvswitch-agent quantum-dhcp-agent quantum-l3-agent quantum-metadata-agent 编辑 /etc/quantum/api-paste.ini:

sed -i 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf 3.2KVM

确保硬件支持虚拟化：

apt-get install cpu-checker kvm-ok 安装kvm

apt-get install -y kvmlibvirt-bin pm-utils 编辑/etc/libvirt/qemu.conf文件，使得cgroup_device_acl与下面相同：

cgroup_device_acl = [ \"/dev/null\\"/dev/random\\"/dev/ptmx\\"/dev/rtc\] 删除默认的网桥（也可以不删除，不会有影响）

nova-manage service list 4. 启动虚拟机

为该租户admin创建一个内部网络（查看租户Id，命令为keystone tenant-list）：

quantum net-create --tenant-id $put_id_of_adminadmin_int 创建子网：

quantum subnet-create --tenant-id $put_id_of_adminadmin_int10.0.0.0/24 创建路由：

quantum router-create --tenant-id $put_id_of_adminrouter_admin 把路由加入子网

quantum router-interface-add $put_router_admin_id_here $put_subnet_id_here 创建外部网络：

quantum net-create --tenant-id $put_id_of_service_tenant ext_net --router:external=True *Note： $id_of_service_tenant 来自租户“service”，可用keystone tenant-list 查看获取；创建外网用子网192.168.1.x：

quantum subnet-create --tenant-id $put_id_of_service_tenant --allocation-pool start=192.168.1.10X,end=192.168.1.1XX --gateway 192.168.1.1 ext_net 192.168.1.0/24 --enable_dhcp=False 关联外网和admin的路由：

quantum router-gateway-set $put_router_tenantA_id_here $put_id_of_ext_net_here 5. Windows镜像制作方法

apt-get install virt-manager(下载虚拟机管理器)

在桌面上的Applications-System Tools -Virtual Machine Manager 打开虚拟机管理器 902b，94de

下载驱动

OpenStack只支持Virtio总线的磁盘，但是windows本身没有Virtio的相关驱动程序，所以首先需要先下载相关驱动程序，下载地址

http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/bin/。

启动管理程序

见上一篇CentOS6.3下为OpenStack制作CentOS镜像。

创建虚拟机

点击创建虚拟机按钮打开创建虚拟机对话框，先通过iso文件生成一个虚拟机，在点击Finish

弹出虚拟机对话框后按下图所示操作： 1.选择Force off关闭虚拟机；

2.打开配置页，修改磁盘的类型为Virtio；

3.点击左下角的添加硬件按钮添加一个光驱，并关联到下载的驱动程序镜像文件； 4.重新打开虚拟机电源。

安装驱动

当安装程序进行到选择磁盘的时候发现没有可用的磁盘，此时选择加载驱动程序》浏览》选择驱动程序所在文件夹，会列出相关的驱动程序，安装好磁盘驱动就可以看到磁盘了。重复上述步骤安装气球程序，在程序列表时去掉下面的隐藏不兼容驱动选项，还可安装其它如网卡等驱动，如下图所示：

后期处理

安装完系统并重启后，安装所需要的软件，开启远程桌面，设置防火墙允许ping（可以直接关闭）。

需要注意的是，在G版的OpenStack启动后，虚拟机的网卡类型为Virtio，不再是default(…) 那个类型，所以还必须把虚拟机的网卡类型改为Virtio型，然后再安装Virtio的网卡驱动，最后再上传！（安装Virtio网卡驱动，可以给虚拟机增加一个存储盘，选择Floppy软盘，然后把virtio-win-1.1.16.vfd驱动挂载上去，启动虚拟机，然后更新网卡驱动就可以了）

上传镜像

到这里镜像就做好了，关闭虚拟机，通过glance命令上传就是了

glance add name=\"win7\" is_public=true container_format=ovfdisk_format=qcow2 < /var/lib/libvirt/images/win7.img

6. 相关问题及解决办法

6.1 Cinder错误：

https://review.openstack.org/#/c/27938/2/cinder/volume/iscsi.py 修改 /usr/share/pyshared/cinder/volume/iscsi.py

6.2 service iscsitarget restart 出现如下错误：

FATAL: Module iscsi_trgt not found 尝试下面的解决办法：

#mkdir /lib/modules/`uname -r`/kernel/iscsi #find / -name “iscsi_trgt.ko”

#cpiscsi_trgt.ko /lib/modules/`uname -r`/kernel/iscsi #depmod–aq

6.3 Attach Volume的问题：

1. nova.openstack.common.rpc.amqpStderr: 'iscsiadm: No session found.\\n'

/etc/iscsi/iscsid.conf里面的startup setting选项中的Node.startup 设置成为automatic应该就可以了。

2. WARNING nova.virt.libvirt.utils [XXXX] systool is not installed apt-get install sysfsutils

https://answers.launchpad.net/nova/+question/226471

3. WARNING nova.virt.libvirt.volume [XXX] ISCSI volume not yet found at: vdc. Will rescan & retry. Try number: 0

6.4 OVS插件启动不了的问题

关于quantum-plugin-openvswitch-agent ：这是quantum利用ovs的一个插件。这个是我在安装G版的时候最容易出错的地方。在这里给大家详细描述一下。

在网络节点装完quantum以后重启所有服务，请仔细观察 service quantum-plugin-openvswitch-agent status，是否是start running，如果不是，恭喜你，遇到问题了。

同样在计算节点装完这个服务之后重启服务，没有问题，ok ,重启电脑，再看service quantum-plugin-openvswitch-agent status，是否是 stop/waiting呢？如果是，那么遇到问题了。

这个时候，在网络节点把quantum和ovs完全卸载。卸载的指令：

apt-getautoremove -y --purge quantum-plugin-openvswitch-agent quantum-dhcp-agent quantum-l3-agent quantum-metadata-agent apt-getautoremove -y --purge openvswitch-switch openvswitch-datapath-dkms 等待卸载完，重启电脑，再重新安装，ovs和quantum各个组件。我和我项目组的分析出现这问题的原因可能是包的依赖问题，反正是目前没有好的解决办法。

计算节点同样做这两个动作，只是计算节点quantum没安装这么多的东西。

ok,在Control节点或者NetWork节点执行 quantum agent-list，看alive下是否都是笑脸呢？如果是，恭喜你，这个问题解决了 http://blog.csdn.net/u010818955/article/details/8981303
