CentOS6.4部署OpenStack Havana(Nova-Network版) (下)
CentOS6.4部署OpenStack Havana(Nova-Network版) (上)7.4.nova测试：
(1).创建网络：
# nova network-create vmnet --fixed-range-v4=10.1.1.0/24 --bridge-interface=br1 --multi-host=T
#nova network-list
+--------------------------------------+-------+-------------+
| ID | Label | Cidr |

| d3bc4874-2b4b-4abf-b963-0e5ae69b7b31 | vmnet | 10.1.1.0/24 |
+--------------------------------------+-------+-------------+
# nova-manage network list

(2).设置安全组：
# nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range| Source Group |
+-------------+-----------+---------+-----------+--------------+
| tcp | 22 | 22 | 0.0.0.0/0 | |
+-------------+-----------+---------+-----------+--------------+
# nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range| Source Group |
+-------------+-----------+---------+-----------+--------------+
| icmp | -1 | -1 | 0.0.0.0/0 | |
+-------------+-----------+---------+-----------+--------------+
(3).创建虚拟机实例：
查看可用镜像：

8.安装配置Horizon
(1).安装Horizon
# yum -y install openstack-dashboard
(2).修改local_settings文件,将DEBUG = False修改为DEBUG = True
# vi /etc/openstack-dashboard/local_settings
DEBUG = True
……
(3).修改httpd.conf文件，将#ServerName www.example.com:80修改为ServerName 192.168.10.21:80
# vi /etc/httpd/conf/httpd.conf
#ServerName www.example.com:80
ServerName 192.168.10.21:80
(4).修改local_settings.py文件，将"Member"修改为"admin"
# find / -name local_settings.py
/usr/share/openstack-dashboard/openstack_dashboard/local/local_settings.py
# cat /usr/share/openstack-dashboard/openstack_dashboard/local/local_settings.py | grep OPENSTACK_KEYSTONE_DEFAULT_ROLE
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "Member"
# vi /usr/share/openstack-dashboard/openstack_dashboard/local/local_settings.py
#OPENSTACK_KEYSTONE_DEFAULT_ROLE = "Member"
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "admin"
(5).启动http服务，设置开机自启动
# service httpd start
# chkconfig httpd on
(6).重启nova-api服务
# service openstack-nova-api restart
(7).添加防火墙策略
# iptables -I INPUT -p tcp --dport 80 -j ACCEPT
# iptables -I INPUT -p tcp -m multiport --dports 5900:6000 -j ACCEPT
# iptables -I INPUT -p tcp --dport 6080 -j ACCEPT
# service iptables save
Horizon安装完成，使用http://192.168.10.21/dashboard访问openstack web界面。

9.添加新项目
(1).为操作员用户创建一个tenant：
# keystone tenant-create --name=manager --description='Manager Tenant'
(2).创建操作员用户：
# keystone user-create --name=manager --pass=password --email=manager@chensh.net
(3).创建一个管理角色manager：
# keystone role-create --name=manager
(4).将manager角色添加到用户：
# keystone user-role-add --user=manager --tenant=manager --role=manager
(5).将nova角色添加到用户：
# keystone user-role-add --user=nova --tenant=service --role=manager

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
# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
# rpm -Uvh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
# yum install http://repos.fedorapeople.org/repos/openstack/openstack-havana/rdo-release-havana-7.noarch.rpm
(2).配置/etc/hosts文件
# 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
# 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"
# 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：
# 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
# setenforce 0
(5).修改/etc/sysctl.conf参数：
# vi /etc/sysctl.conf
……………………
net.ipv4.ip_forward = 1
……………………
#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：
# yum -y install ntpdate
(2).设置时间同步：
# ntpdate 192.168.10.21
31 Mar 16:17:03 ntpdate: the NTP socket is in use, exiting
(3).设置计划任务：
# 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：
# 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：
# source .bash_profile
4.安装配置libvirt服务
(1).安装libvirt服务：
# yum -y install qemu-kvm libvirt
(2)启动libvirt服务：
# service libvirtd start
(3)查看net-list，发现default：
# virsh net-list
Name State Autostart Persistent
--------------------------------------------------
default active yes yes
(4)删除default，即virbr0：
# virsh net-destroy default
Network default destroyed
# virsh net-undefine default
Network default has been undefined
(5)重启libvirtd服务，设置开机自启动：
# service libvirtd restart
# chkconfig libvirtd on
5.安装MySQL客户端
(1).安装mysql客户端
# yum -y install mysql
(2).检查mysql数据库连通性
# 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
# yum -y install openstack-nova-compute openstack-nova-network openstack-nova-scheduler
(2).修改nova配置文件
# vi /etc/nova/nova.conf
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
sql_connection=mysql://nova:nova@192.168.10.21/nova
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：
# cp -r /var/lib/nova/ /openstack/lib/
# chown -R nova:nova /openstack/lib/nova/
(3).启动nova相关服务，设置开机自启动
# service messagebus start
# chkconfig messagebus on
# service openstack-nova-compute start
# service openstack-nova-network start
# chkconfig openstack-nova-compute on
# 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
