OpenStack实战

准备环境

controller 10.0.0.11

compute1   10.0.0.31

常用服务端口

mariadb：3306

memcached:11211

消息队列：5672和25672

时间同步：123和323

keystone：5000和35357

glance：9191和9292

nova：6080,novncproxy：8774,nova-api：8775

yum源配置

cd /etc/yum.repos.d/
ls
mkdir qiangge
mv *.repo qiangge
ls
echo ‘[openstack]
name=openstack
baseurl=http://192.168.21.92/repo/ 

gpgcheck=0

[local]
name=local
baseurl=http://192.168.21.92/local/ 

gpgcheck=0‘ >openstack.repo
yum clean all
yum makecache

时间同步

controller上面配置一个时间服务器，上游时间，ntp3.aliyun.com

allow:10/8

compute1与controller同步上游时间：controller

在所有节点安装chrony服务

yum install chrony -y

controller上

编辑/etc/chrony.conf文件修改内容如下

修改一：第3行：   server ntp3.aliyun.com iburst
修改二：第22行：  allow 10/8

启动chronyd

systemctl restart chronyd
systemctl enable chronyd

compute1

编辑/etc/chrony.conf文件修改内容如下

修改一：第3行：server controller iburst

确定您的计算节点是否支持虚拟机的硬件加速

egrep -c ‘(vmx|svm)‘ /proc/cpuinfo

如果这个命令返回了 one or greater 的值，那么你的计算节点支持硬件加速且不需要额外的配置。

如果这个命令返回了 zero 值，那么你的计算节点不支持硬件加速。你必须配置 libvirt 来使用 QEMU 去代替 KVM

在 /etc/nova/nova.conf 文件的 [libvirt] 区域做出如下的编辑：

[libvirt]
...
virt_type = qemu

启动计算服务及其依赖，并将其配置为随系统自动启动

systemctl enable libvirtd.service openstack-nova-compute.service
systemctl start libvirtd.service openstack-nova-compute.service

Dashboard

contorller

安装软件包

yum install openstack-dashboard

编辑/etc/openstack-dashboard/local_settings文件

在 controller 节点上配置仪表盘以使用 OpenStack 服务：

OPENSTACK_HOST = "controller"

允许所有主机访问仪表板：

ALLOWED_HOSTS = [‘*‘, ]

配置 memcached 会话存储服务：

SESSION_ENGINE = ‘django.contrib.sessions.backends.cache‘

CACHES = {
    ‘default‘: {
    ‘BACKEND‘: ‘django.core.cache.backends.memcached.MemcachedCache‘,
    ‘LOCATION‘: ‘controller:11211‘,
    }
}

启用第3版认证API:

OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST

启用对域的支持

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True

配置API版本:

OPENSTACKAPIVERSIONS = { "identity": 3, "image": 2, "volume": 2, } 通过仪表盘创建用户时的默认域配置为 default :

OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "default"

通过仪表盘创建的用户默认角色配置为 user ：

OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

如果您选择网络参数1，禁用支持3层网络服务：

OPENSTACK_NEUTRON_NETWORK = {
    ...
    ‘enable_router‘: False,
    ‘enable_quotas‘: False,
    ‘enable_distributed_router‘: False,
    ‘enable_ha_router‘: False,
    ‘enable_lb‘: False,
    ‘enable_firewall‘: False,
    ‘enable_vpn‘: False,
    ‘enable_fip_topology_check‘: False,
}

可以选择性地配置时区：

TIME_ZONE = "Aisa/Shanghai"

重启web服务器以及会话存储服务

systemctl restart httpd.service memcached.service

验证操作

在浏览器中输入http://controller/dashboard访问仪表盘。

验证使用admin或者demo用户凭证和default域凭证。

启动实例

创建提供者网络

在控制节点上，加载 admin 凭证来获取管理员能执行的命令访问权限

. admin-openrc

创建网络

neutron net-create --shared --provider:physical_network provider --provider:network_type flat provider

创建子网

neutron subnet-create --name provider --allocation-pool start=10.0.0.101,end=10.0.0.250  --dns-nameserver 223.5.5.5 --gateway 10.0.0.254 provider 10.0.0.0/24

检查验证

neutron net-list
neutron subnet-list

创建m1.nano规格的主机

使用m1.nano规格的主机来加载CirrOS镜像

openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano
openstack flavor list

生成和添加秘钥对：

ssh-keygen -q -N ""
openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey

验证公钥的添加

openstack keypair list

添加规则到 default 安全组

允许 ICMP (ping)：

openstack security group rule create --proto icmp default

允许安全 shell (SSH) 的访问：

openstack security group rule create --proto tcp --dst-port 22 default
