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

  1. sudo su
复制代码


添加 Grizzly 源 [Only for Ubuntu 12.04]:

  1. apt-get install -y ubuntu-cloud-keyring
  2. 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:

  1. apt-get update -y
  2. apt-get upgrade -y
  3. 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

  1. #For Exposing OpenStack API over the internet
  2. auto eth1
  3. iface eth1 inet static
  4. address 192.168.100.51
  5. netmask 255.255.255.0
  6. gateway 192.168.100.1
  7. dns-nameservers 8.8.8.8
  9. #Not internet connected(used for OpenStack management)
  10. auto eth0
  11. iface eth0 inet static
  12. address 10.10.10.51
  13. netmask 255.255.255.0
复制代码


重新启动网络

  1. service networking restart
复制代码


2.3. MySQL & RabbitMQ安装


安装 MySQL:

  1. 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

  1. sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mysql/my.cnf
  2. service mysql restart
复制代码

对于上面命令不了解可以参考下面内容：

2.5. 其他


安装其它服务:

  1. apt-get install -y vlan bridge-utils
复制代码


启动 IP_Forwarding:

  1. sed -i 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf
  3. # To save you from rebooting, perform the following
  4. sysctl net.ipv4.ip_forward=1
复制代码


2.6. Keystone

安装Keystone

  1. apt-get install -y keystone
复制代码


在文件 /etc/keystone/keystone.conf  中添加如下语句

  1. 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

  1. service keystone restart
  2. keystone-manage db_sync
复制代码


下载keystone_basic.sh，keystone_endpoints_basic.sh并执行脚本

  1. #Modify the **HOST_IP** and **EXT_HOST_IP** variables before executing the scripts
  3. wget https://raw.github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/OVS_MultiNode/KeystoneScripts/keystone_basic.sh
  4. wget https://raw.github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/OVS_MultiNode/KeystoneScripts/keystone_endpoints_basic.sh
  6. chmod +x keystone_basic.sh
  7. chmod +x keystone_endpoints_basic.sh
  9. ./keystone_basic.sh
  10. ./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）

  1. nano creds
  3. #Paste the following:
  4. export OS_TENANT_NAME=admin
  5. export OS_USERNAME=admin
  6. export OS_PASSWORD=admin_pass
  7. export OS_AUTH_URL="http://192.168.100.51:5000/v2.0/"
  9. # Load it:
  10. source creds
复制代码


使用CLI命令，测试使用安装成功

  1. keystone user-list
复制代码


2.7. Glance

安装Glance

  1. apt-get install -y glance
复制代码

更新/etc/glance/glance-api-paste.ini 文件

  1. [filter:authtoken]
  2. paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
  3. delay_auth_decision = true
  4. auth_host = 10.10.10.51
  5. auth_port = 35357
  6. auth_protocol = http
  7. admin_tenant_name = service
  8. admin_user = glance
  9. admin_password = service_pass
复制代码



注释与说明：

即使找到上面[filter:authtoken]，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

  1. [filter:authtoken]
  2. paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
  3. auth_host = 10.10.10.51
  4. auth_port = 35357
  5. auth_protocol = http
  6. admin_tenant_name = service
  7. admin_user = glance
  8. admin_password = service_pass
复制代码
  1. [paste_deploy]
  2. 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

  1. 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：

  1. sql_connection = mysql://glanceUser:glancePass@10.10.10.51/glance
复制代码
  1. [paste_deploy]
  2. 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:

  1. service glance-api restart; service glance-registry restart
复制代码


同步 glance 数据库:

  1. glance-manage db_sync
复制代码


导入img

  1. 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
复制代码


测试安装是否成功

  1. glance image-list
复制代码

  9. enable_tunneling = True
  11. #Firewall driver for realizing quantum security group function
  12. [SECURITYGROUP]
  13. firewall_driver = quantum.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
复制代码


注释与说明：
 



我们看到上面链接替换为sql_connection = mysql://quantumUser:quantumPass@10.10.10.51/quantum即可。下面操作同理





编辑 /etc/quantum/api-paste.ini

  1. [filter:authtoken]
  2. paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
  3. auth_host = 10.10.10.51
  4. auth_port = 35357
  5. auth_protocol = http

  3. apt-get dist-upgrade -y
复制代码


安装 ntp 服务:

  1. apt-get install -y ntp
复制代码


配置NTP保持与控制节点时间同步:

  1. #Comment the ubuntu NTP servers
  2. sed -i 's/server 0.ubuntu.pool.ntp.org/#server 0.ubuntu.pool.ntp.org/g' /etc/ntp.conf
  3. sed -i 's/server 1.ubuntu.pool.ntp.org/#server 1.ubuntu.pool.ntp.org/g' /etc/ntp.conf
  4. sed -i 's/server 2.ubuntu.pool.ntp.org/#server 2.ubuntu.pool.ntp.org/g' /etc/ntp.conf
  5. sed -i 's/server 3.ubuntu.pool.ntp.org/#server 3.ubuntu.pool.ntp.org/g' /etc/ntp.conf
  7. #Set the compute node to follow up your conroller node
  8. sed -i 's/server ntp.ubuntu.com/server 10.10.10.51/g' /etc/ntp.conf
  10. service ntp restart
复制代码


安装vlan 与网桥配置工具bridge-utils

  1. apt-get install -y vlan bridge-utils
复制代码


启动 IP_Forwarding:

  1. sed -i 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf
复制代码


4.2.网络配置

  1. # OpenStack management
  2. auto eth0
  3. iface eth0 inet static
  4. address 10.10.10.53
  5. netmask 255.255.255.0
  7. # VM Configuration
  8. auto eth1
  9. iface eth1 inet static
  10. address 10.20.20.53
  11. netmask 255.255.255.0
复制代码


4.3 KVM

确保你的硬件支持虚拟化:

  1. apt-get install -y cpu-checker
  2. kvm-ok
复制代码

上面命令分别执行，当我们看到如下信息时，其实可以的。因为虽然不支持加速，但是是可以使用的。

 


如果上面是好的，我们安装和配置KVM

  1. apt-get install -y kvm libvirt-bin pm-utils
复制代码


添加 cgroup_device_acl 数组到文 /etc/libvirt/qemu.conf:

  1. cgroup_device_acl = [
  2. "/dev/null", "/dev/full", "/dev/zero",
  3. "/dev/random", "/dev/urandom",
  4. "/dev/ptmx", "/dev/kvm", "/dev/kqemu",
  5. "/dev/rtc", "/dev/hpet","/dev/net/tun"
  6. ]
复制代码


如下图所示

 



删除virtual bridge（执行下面命令即可）

  1. virsh net-destroy default
  2. virsh net-undefine default
复制代码


更新文件 /etc/libvirt/libvirtd.conf:

  1. listen_tls = 0
  2. listen_tcp = 1
  3. auth_tcp = "none"
复制代码


注释与说明：
上面可以找到相应的注释，去掉注释即可。

 


这里面因为注释内容比较多，可以使用查询如下图所示：我们输入/listten_tls回车即可找到相应内容。
 


在文件 /etc/init/libvirt-bin.conf中添加 libvirtd_opts 变量:

  1. env libvirtd_opts="-d -l"
复制代码


注释与说明：
如下图位置所示
 



编辑 /etc/default/libvirt-bin 文件

  1. libvirtd_opts="-d -l"
复制代码

如下图红色箭头所示，我们只要在libvirtd_opts="-d"中添加-1即可，即为libvirtd_opts="-d -l"
 



重 libvirt service与 service libvirt-bin:

  1. service dbus restart && service libvirt-bin restart
复制代码

看到如下信息：
 


4.4. OpenVSwitch

安装 openVSwitch:

  1. apt-get install -y openvswitch-switch openvswitch-datapath-dkms
复制代码


创建 bridges:

  1. #br-int will be used for VM integration
  2. ovs-vsctl add-br br-int
复制代码


4.5. Quantum
安装 Quantum openvswitch 代理:

  1. 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:

  1. #Under the database section
  2. [DATABASE]
  3. sql_connection = mysql://quantumUser:quantumPass@10.10.10.51/quantum
  5. #Under the OVS section
  6. [OVS]
  7. tenant_network_type = gre
  8. tunnel_id_ranges = 1:1000
  9. integration_bridge = br-int
  10. tunnel_bridge = br-tun
  11. local_ip = 10.20.20.53
  12. enable_tunneling = True
  14. #Firewall driver for realizing quantum security group function
  15. [SECURITYGROUP]
  16. 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:

  1. rabbit_host = 10.10.10.51
  3. #And update the keystone_authtoken section
  5. [keystone_authtoken]
  6. auth_host = 10.10.10.51
  7. auth_port = 35357
  8. auth_protocol = http
  9. admin_tenant_name = service
  10. admin_user = quantum
  11. admin_password = service_pass
  12. signing_dir = /var/lib/quantum/keystone-signing
复制代码

  1. service quantum-plugin-openvswitch-agent restart
复制代码




4.6. Nova

安装nova所需要组件:

  1. apt-get install -y nova-compute-kvm
复制代码


修改文件  /etc/nova/api-paste.ini   authtoken 部分   

  1. [filter:authtoken]
  2. paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
  3. auth_host = 10.10.10.51
  4. auth_port = 35357
  5. auth_protocol = http
  6. admin_tenant_name = service
  7. admin_user = nova
