二、管理节点安装(OpenStack)

1.基础配置

操作系统使用CentOS-6.4-x86_64-minimal.iso，安装过程省略，本文采用yum源安装。

(1).导入第三方安装源

[root@openstack ~]# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

[root@openstack ~]# rpm -Uvh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm

[root@openstack ~]# yum install http://repos.fedorapeople.org/repos/openstack/openstack-havana/rdo-release-havana-7.noarch.rpm

(2).配置/etc/hosts文件

[root@openstack ~]# vi /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.10.21 openstack

192.168.10.22 node01

(3).配置网络

[root@openstack ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"

BOOTPROTO="static"

HWADDR="E4:1F:13:45:AB:C8"

ONBOOT="yes"

IPADDR=192.168.10.21

NETMASK=255.255.255.0

GATEWAY=192.168.10.1

DEVICE="eth1"

BOOTPROTO="none"

HWADDR="E4:1F:13:45:AB:CA"

ONBOOT="yes"

TYPE="Ethernet"

(4).关闭selinux：

[root@openstack ~]# more /etc/selinux/config

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

# enforcing - SELinux security policy is enforced.

# permissive - SELinux prints warnings instead of enforcing.

# disabled - SELinux is fully disabled.

SELINUX=disabled

# SELINUXTYPE= type of policy in use. Possible values are:

# targeted - Only targeted network daemons are protected.

# strict - Full SELinux protection.

SELINUXTYPE=targeted

[root@openstack ~]# setenforce 0

(5).修改/etc/sysctl.conf参数：

[root@openstack ~]# vi /etc/sysctl.conf

……………………

net.ipv4.ip_forward = 1

……………………
[root@openstack ~]#sysctl -p #使sysctl.conf配置生效

2.安装配置NTP服务

(1).安装NTP服务：

[root@openstack ~]# yum -y install ntp

(2).配置NTP服务：

[root@openstack ~]# vi /etc/ntp.conf

driftfile /var/lib/ntp/drift

restrict default ignore

restrict 127.0.0.1

restrict 192.168.10.0 mask 255.255.255.0 nomodify notrap

server ntp.api.bz

server 127.127.1.0 # local clock

fudge 127.127.1.0 stratum 10

keys /etc/ntp/keys

(3).启动NTP服务,设置开机自启动：

[root@openstack ~]# service ntpd start

[root@openstack ~]# chkconfig ntpd on

3.配置安装MySQL：

(1).安装MySQL服务：

[root@openstack ~]# yum -y install mysql mysql-server MySQL-python

(2).修改MySQL配置文件：

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

user=mysql

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

bind-address = 0.0.0.0 #设置监听IP地址0.0.0.0

[mysqld_safe]

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

(3).启动MqSQL服务，设置开机自启动：

[root@openstack ~]# service mysqld start

[root@openstack ~]# chkconfig mysqld on

(4).修改MySQL密码为passwd：

[root@openstack ~]# mysqladmin -uroot password 'passwd'; history -c

4.安装配置qpid服务

(1).安装qpid服务：

[root@openstack ~]# yum -y install qpid-cpp-server memcached

(2).修改/etc/qpidd.conf配置文件,将auth设置为no：

[root@openstack ~]# vi/etc/qpidd.conf

……………………

auth=no

(3).启动qpid服务，设置开机启动：

[root@openstack ~]# service qpidd start

[root@openstack ~]# chkconfig qpidd on

(4).安装OpenStack工具包：

[root@openstack ~]# yuminstall -y openstack-utils

5.安装配置KeyStone

5.1.初始化KeyStone：

(1).安装KeyStone服务：

[root@openstack ~]# yum -y install openstack-keystone

(2).创建keystone数据库，修改配置文件中的数据库链接：

[root@openstack ~]# openstack-db --init --service keystone

(3).修改配置文件中的数据库链接：

[root@openstack ~]# openstack-config --set /etc/keystone/keystone.conf sql connection mysql://keystone:keystone@localhost/keystone

(4).使用openssl随即生成一个令牌，将其存储在配置文件中：

[root@openstack ~]# export SERVICE_TOKEN=$(openssl rand -hex 10) //随机生成SERVICE_TOKEN值，请牢记

[root@openstack ~]# export SERVICE_ENDPOINT=http://127.0.0.1:35357/v2.0

[root@openstack ~]# mkdir /root/config

[root@openstack ~]# echo $SERVICE_TOKEN > /root/config/ks_admin_token.txt

[root@openstack ~]# cat /root/config/ks_admin_token .txt

12dd70ede7c9d9d3ed3c

[root@openstack ~]# openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_token $SERVICE_TOKEN

*注：将生成的SERVICE_TOKEN值写入文件中保存，以备后续使用，后面涉及到的SERVICE_TOKEN值都是在ks_admin_token.txt文件中获取的。所以一旦写入文件，不要再次运行命令生成SERVICE_TOKEN，否则前后不一致会为调试带来麻烦。

(5).默认情况下keysonte使用PKI令牌。创建签名密钥和证书：

[root@openstack ~]# keystone-manage pki_setup --keystone-user keystone --keystone-group keystone

[root@openstack ~]# chown -R keystone:keystone /etc/keystone/* /var/log/keystone/keystone.log

(6).启动keystone服务，设置开机自启动：

[root@openstack ~]# service openstack-keystone start

[root@openstack ~]# chkconfig openstack-keystone on

5.2.定义Users、Tenants and Roles

(1).修改.bash_profile文件，添加以下参数：

[root@openstack ~]# vi .bash_profile

………………

export OS_USERNAME=admin

export OS_TENANT_NAME=admin

export OS_PASSWORD=password

export OS_AUTH_URL=http://127.0.0.1:5000/v2.0

export SERVICE_ENDPOINT=http://127.0.0.1:35357/v2.0

export SERVICE_TOKEN=12dd70ede7c9d9d3ed3c

………………

执行下面的命令使变量即时生效：

[root@openstack ~]# source .bash_profile

(2).为管理员用户创建一个tenant，为openstack其他服务的用户创建一个tenant：

[root@openstack ~]# keystone tenant-create --name=admin --description='Admin Tenant'

[root@openstack ~]# keystone tenant-create --name=service --description='Service Tenant'

(3).创建一个管理员用户admin：

[root@openstack ~]# keystoneuser-create --name=admin --pass=password --email=keystone@chensh.net

(4).创建一个管理员角色admin：

[root@openstack ~]# keystone role-create --name=admin

(5).将角色添加到用户：

[root@openstack ~]# keystone user-role-add --user=admin --tenant=admin --role=admin

5.3.定义Services 和 API Endpoints

(1).为KeyStone创建一个服务：

[root@openstack ~]# keystoneservice-create --name=keystone --type=identity --description="KeystoneIdentity Service"

(2).使用服务ID创建一个endpoint：

[root@openstack ~]# vi /root/config/keystone.sh

#!/bin/bash

my_ip=192.168.10.21

service=$(keystone service-list | awk '/keystone/ {print $2}')

keystone endpoint-create --service-id=$service --publicurl=http://$my_ip:5000/v2.0 --internalurl=http://$my_ip:5000/v2.0 --adminurl=http://$my_ip:35357/v2.0

7.安装配置Nova

7.1.初始化Nova

(1).安装nova：

[root@openstack ~]# yum -y install openstack-nova

(2).创建nova数据库：

[root@openstack ~]# openstack-db --init --service nova

7.2.创建User，定义Services 和 API Endpoints

(1).编写脚本：

[root@openstack ~]# vi /root/config/nova-user.sh

#!/bin/sh

my_ip=192.168.10.21

keystone user-create --name=nova --pass=service --email=nova@example.com

keystone user-role-add --user=nova --tenant=service --role=admin

keystone service-create --name=nova --type=compute --description="Nova Compute Service"

service=$(keystone service-list | awk '/nova/ {print $2}')

keystone endpoint-create --service-id=$service --publicurl=http://$my_ip:8774/v2/%$tenant_id$s --internalurl=http://$my_ip:8774/v2/%$tenant_id$s --adminurl=http://$my_ip:8774/v2/%$tenant_id$s

(2).运行脚本，创建用户、服务及api endpoint：

[root@openstack ~]# sh /root/config/nova-user.sh

7.3.配置nova服务：

(1).修改/etc/nova.conf配置文件:

[root@openstack ~]# vi /etc/nova/nova.conf

[DEFAULT]

my_ip = 192.168.10.21

auth_strategy = keystone

state_path = /openstack/lib/nova

verbose=True

allow_resize_to_same_host = true

rpc_backend = nova.openstack.common.rpc.impl_qpid

qpid_hostname = 192.168.10.21

libvirt_type = kvm

glance_api_servers = 192.168.10.21:9292

novncproxy_base_url = http://192.168.10.21:6080/vnc_auto.html

vncserver_listen = $my_ip

vncserver_proxyclient_address = $my_ip

vnc_enabled = true

vnc_keymap = en-us

network_manager = nova.network.manager.FlatDHCPManager

firewall_driver = nova.virt.firewall.NoopFirewallDriver

multi_host = True

flat_interface = eth1

flat_network_bridge = br1

public_interface = eth0

instance_usage_audit = True

instance_usage_audit_period = hour

notify_on_state_change = vm_and_task_state

notification_driver = nova.openstack.common.notifier.rpc_notifier

compute_scheduler_driver=nova.scheduler.simple.SimpleScheduler

[hyperv]

[zookeeper]

[osapi_v3]

[rpc_notifier2]

[matchmaker_redis]

[ssl]

[trusted_computing]

[upgrade_levels]

[matchmaker_ring]

[vmware]

[spice]

[keystone_authtoken]

auth_host = 127.0.0.1

auth_port = 35357

auth_protocol = http

admin_user = nova

admin_tenant_name = service

admin_password = service

因上述配置文件中修改了instances实例存放的位置，还需要作一下操作：

修改instances路径，设置目录权限：

[root@openstack ~]# cp -r /var/lib/nova/ /openstack/lib/

[root@openstack ~]# chown -R nova:nova /openstack/lib/nova/

(2).配置libvirtd服务，删除virbr0

启动libvirt服务：

[root@openstack ~]# service libvirtd start

查看net-list，发现default：

[root@openstack ~]# virsh net-list

Name State Autostart Persistent

--------------------------------------------------

default active yes yes

删除default，即virbr0：

[root@openstack ~]# virsh net-destroy default

Network default destroyed

[root@openstack ~]# virsh net-undefine default

Network default has been undefined

重启libvirtd服务，设置开机自启动：

[root@openstack ~]# service libvirtd restart

[root@openstack ~]# chkconfig libvirtd on

(3).启动nova相关服务，设置开机自启动

[root@openstack ~]# service messagebus start

[root@openstack ~]# chkconfig messagebus on

启动nova服务，采用network网络服务：

[root@openstack ~]# service openstack-nova-api start

[root@openstack ~]# service openstack-nova-cert start

[root@openstack ~]# service openstack-nova-consoleauth start

[root@openstack ~]# service openstack-nova-scheduler start

[root@openstack ~]# service openstack-nova-conductor start

[root@openstack ~]# service openstack-nova-novncproxy start

[root@openstack ~]# service openstack-nova-compute start

[root@openstack ~]# service openstack-nova-network start

[root@openstack ~]# chkconfig openstack-nova-api on

[root@openstack ~]# chkconfig openstack-nova-cert on

[root@openstack ~]# chkconfig openstack-nova-consoleauth on

[root@openstack ~]# chkconfig openstack-nova-scheduler on

[root@openstack ~]# chkconfig openstack-nova-conductor on

[root@openstack ~]# chkconfig openstack-nova-novncproxy on

[root@openstack ~]# chkconfig openstack-nova-compute on

[root@openstack ~]# chkconfig openstack-nova-network on

------------------------------------------------------------------------------------------

7.4.nova测试：

(1).创建网络：

[root@openstack ~]# nova network-create vmnet --fixed-range-v4=10.1.1.0/24 --bridge-interface=br1 --multi-host=T

三、计算节点安装(Node01)

1.基础配置

操作系统使用CentOS-6.4-x86_64-minimal.iso，安装过程省略，本文采用yum源安装。

(1).导入第三方安装源

[root@node01 ~]# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

[root@node01 ~]# rpm -Uvh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm

[root@node01 ~]# yum install http://repos.fedorapeople.org/repos/openstack/openstack-havana/rdo-release-havana-7.noarch.rpm

(2).配置/etc/hosts文件

[root@node01 ~]# vi /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.10.21 openstack

192.168.10.22 node01

(3).配置网络

[root@node01 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"

BOOTPROTO="static"

HWADDR="E4:1F:13:45:AB:C1"

ONBOOT="yes"

IPADDR=192.168.10.22

NETMASK=255.255.255.0

GATEWAY=192.168.10.1

TYPE="Ethernet"

[root@openstack ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE="eth1"

BOOTPROTO="none"

HWADDR="E4:1F:13:45:AB:C3"

ONBOOT="yes"

TYPE="Ethernet"

(4).关闭selinux：

[root@node01 ~]# more /etc/selinux/config

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

# enforcing - SELinux security policy is enforced.

# permissive - SELinux prints warnings instead of enforcing.

# disabled - SELinux is fully disabled.

SELINUX=disabled

# SELINUXTYPE= type of policy in use. Possible values are:

# targeted - Only targeted network daemons are protected.

# strict - Full SELinux protection.

SELINUXTYPE=targeted

[root@node01 ~]# setenforce 0

(5).修改/etc/sysctl.conf参数：

[root@node01 ~]# vi /etc/sysctl.conf

……………………

net.ipv4.ip_forward = 1

……………………
[root@node01 ~]#sysctl -p #使sysctl.conf配置生效

2.安装配置NTP客户端

(1).安装NTP客户端服务：

[root@node01 ~]# yum -y install ntpdate

(2).设置时间同步：

[root@node01 ~]# ntpdate 192.168.10.21

31 Mar 16:17:03 ntpdate[5848]: the NTP socket is in use, exiting

(3).设置计划任务：

[root@node01 ~]# crontab -e

插入下行内容：

*/5 * * * * ntpdate 192.168.10.21 >> /var/log/ntpdate.log

3.设置环境变量

修改.bash_profile文件，添加以下参数：

[root@node01 ~]# vi .bash_profile

………………

export OS_USERNAME=admin

export OS_TENANT_NAME=admin

export OS_PASSWORD=password

export OS_AUTH_URL=http://192.168.10.21:5000/v2.0

export SERVICE_ENDPOINT=http://192.168.10.21:35357/v2.0

export SERVICE_TOKEN=12dd70ede7c9d9d3ed3c

………………

执行下面的命令使变量即时生效：

[root@node01 ~]# source .bash_profile

4.安装配置libvirt服务

(1).安装libvirt服务：

[root@node01 ~]# yum -y install qemu-kvm libvirt

(2)启动libvirt服务：

[root@node01 ~]# service libvirtd start

(3)查看net-list，发现default：

[root@node01 ~]# virsh net-list

Name State Autostart Persistent

--------------------------------------------------

default active yes yes

(4)删除default，即virbr0：

[root@node01 ~]# virsh net-destroy default

Network default destroyed

[root@node01 ~]# virsh net-undefine default

Network default has been undefined

(5)重启libvirtd服务，设置开机自启动：

[root@node01 ~]# service libvirtd restart

[root@node01 ~]# chkconfig libvirtd on

5.安装MySQL客户端

(1).安装mysql客户端

[root@node01 ~]# yum -y install mysql

(2).检查mysql数据库连通性

[root@node01 ~]# mysql -h 192.168.10.21 -unova -pnova

Welcome to the MySQL monitor. ………………

mysql> quit;

Bye

6.安装配置Nova服务

(1)安装nova-compute、nova-network、nova-scheduler

[root@node01 ~]# yum -y install openstack-nova-compute openstack-nova-network openstack-nova-scheduler

(2).修改nova配置文件

[root@node01 ~]# vi /etc/nova/nova.conf

[DEFAULT]

my_ip = 192.168.10.22

auth_strategy = keystone

state_path = /letv/openstack/lib/nova

verbose=True

allow_resize_to_same_host = true

rpc_backend = nova.openstack.common.rpc.impl_qpid

qpid_hostname = 192.168.10.21

libvirt_type = kvm

glance_api_servers = 192.168.10.21:9292

novncproxy_base_url = http://192.168.10.21:6080/vnc_auto.html

vncserver_listen = 192.168.10.22

vncserver_proxyclient_address = 192.168.10.22

vnc_enabled = true

vnc_keymap = en-us

network_manager = nova.network.manager.FlatDHCPManager

firewall_driver = nova.virt.firewall.NoopFirewallDriver

multi_host = True

flat_interface = eth1

flat_network_bridge = br1

public_interface = eth0

instance_usage_audit = True

instance_usage_audit_period = hour

notify_on_state_change = vm_and_task_state

notification_driver = nova.openstack.common.notifier.rpc_notifier

compute_scheduler_driver=nova.scheduler.simple.SimpleScheduler

[hyperv]

[zookeeper]

[osapi_v3]

[conductor]

[keymgr]

[cells]

[database]

sql_connection=mysql://nova:nova@192.168.10.21/nova

[image_file_url]

[baremetal]

[rpc_notifier2]

[matchmaker_redis]

[ssl]

[trusted_computing]

[upgrade_levels]

[matchmaker_ring]

[vmware]

[spice]

[keystone_authtoken]

auth_host = 192.168.10.21

auth_port = 35357

auth_protocol = http

admin_user = nova

admin_tenant_name = service

admin_password = service

因上管理节点nova.conf配置文件中修改了instances实例存放的位置，还需要作一下操作：

修改路径，设置目录权限：

[root@node01 ~]# cp -r /var/lib/nova/ /openstack/lib/

[root@node01 ~]# chown -R nova:nova /openstack/lib/nova/

(3).启动nova相关服务，设置开机自启动

[root@node01 ~]# service messagebus start

[root@node01 ~]# chkconfig messagebus on

[root@node01 ~]# service openstack-nova-compute start

[root@node01 ~]# service openstack-nova-network start

[root@node01 ~]# chkconfig openstack-nova-compute on

[root@node01 ~]# chkconfig openstack-nova-network on

*******************************************************************************************

OpenStack其他常用命令：

1.list nova服务，包含管理节点和计算节点

[root@openstack ~]# nova service-list
