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
8. #Not internet connected(used for OpenStack management)
9. auto eth0
10. iface eth0 inet static
11. address 10.10.10.51
12. 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：

2.4. RabbitMQ

安装 RabbitMQ:

1. apt-get install -y rabbitmq-server

复制代码

安装 NTP service:

1. apt-get install -y ntp

复制代码

创建数据库:

1. mysql -u root -p
2. #Keystone
3. CREATE DATABASE keystone;
4. GRANT ALL ON keystone.* TO 'keystoneUser'@'%' IDENTIFIED BY 'keystonePass';
5. #Glance
6. CREATE DATABASE glance;
7. GRANT ALL ON glance.* TO 'glanceUser'@'%' IDENTIFIED BY 'glancePass';

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
2. # To save you from rebooting, perform the following
3. 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
2. wget https://raw.github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/OVS_MultiNode/KeystoneScripts/keystone_basic.sh
3. wget https://raw.github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/OVS_MultiNode/KeystoneScripts/keystone_endpoints_basic.sh
4. chmod +x keystone_basic.sh
5. chmod +x keystone_endpoints_basic.sh
6. ./keystone_basic.sh
7. ./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
2. #Paste the following:
3. export OS_TENANT_NAME=admin
4. export OS_USERNAME=admin
5. export OS_PASSWORD=admin_pass
6. export OS_AUTH_URL="http://192.168.100.51:5000/v2.0/"
7. # Load it:
8. 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

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
6. # VM Configuration
7. auto eth1
8. iface eth1 inet static
9. address 10.20.20.53
10. 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
4. #Under the OVS section
5. [OVS]
6. tenant_network_type = gre
7. tunnel_id_ranges = 1:1000
8. integration_bridge = br-int
9. tunnel_bridge = br-tun
10. local_ip = 10.20.20.53
11. enable_tunneling = True
12. #Firewall driver for realizing quantum security group function
13. [SECURITYGROUP]
14. 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
2. #And update the keystone_authtoken section
3. [keystone_authtoken]
4. auth_host = 10.10.10.51
5. auth_port = 35357
6. auth_protocol = http
7. admin_tenant_name = service
8. admin_user = quantum
9. admin_password = service_pass
10. 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:

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
8. admin_password = service_pass
9. signing_dirname = /tmp/keystone-signing-nova
10. # Workaround for https://bugs.launchpad.net/nova/+bug/1154809
11. auth_version = v2.0

复制代码

编辑文件 /etc/nova/nova-compute.conf  

1. [DEFAULT]
2. libvirt_type=kvm
3. libvirt_ovs_bridge=br-int
4. libvirt_vif_type=ethernet
5. libvirt_vif_driver=nova.virt.libvirt.vif.LibvirtHybridOVSBridgeDriver
6. libvirt_use_virtio_for_bridges=True
