[部署篇9]VMWare搭建Openstack——Flat网络设置和horzion安装

一、在 计算节点和网络节点 上做如下配置

注意：如果是单独的计算节点，也需要进行如下配置

0. 计算节点和网络节点的有两个网卡，分别为eth0、eth1

1. 执行如下命令

   sudo ovs-vsctl add-br br-eth1

   sudo ovs-vsctl add-port br-eth1 eth1

2. 编辑/etc/neutron/plugins/ml2/ml2_conf.ini文件，

     [ sudo vi /etc/neutron/plugins/ml2/ml2_conf.ini ]

     更新设置如下：

[ml2_type_flat]

flat_networks = physnet1

[ml2_type_vlan]

network_vlan_ranges = physnet1:1000:2999

# add at the last line

[ovs]

bridge_mappings = physnet1:br-eth1

sm@computer:~$ sudo more /etc/neutron/plugins/ml2/ml2_conf.ini
[ml2]
# (ListOpt) List of network type driver entrypoints to be loaded from
# the neutron.ml2.type_drivers namespace.
#
type_drivers = flat,vlan,gre
# Example: type_drivers = flat,vlan,gre,vxlan

# (ListOpt) Ordered list of network_types to allocate as tenant
# networks. The default value 'local' is useful for single-box testing
# but provides no connectivity between hosts.
#
tenant_network_types = vlan,gre
# Example: tenant_network_types = vlan,gre,vxlan

# (ListOpt) Ordered list of networking mechanism driver entrypoints
# to be loaded from the neutron.ml2.mechanism_drivers namespace.
mechanism_drivers = openvswitch
# Example: mechanism_drivers = openvswitch,mlnx
# Example: mechanism_drivers = arista
# Example: mechanism_drivers = cisco,logger
# Example: mechanism_drivers = openvswitch,brocade
# Example: mechanism_drivers = linuxbridge,brocade

[ml2_type_flat]
# (ListOpt) List of physical_network names with which flat networks
# can be created. Use * to allow flat networks with arbitrary
# physical_network names.
#
flat_networks = physnet1
# Example:flat_networks = physnet1,physnet2
# Example:flat_networks = *

[ml2_type_vlan]
# (ListOpt) List of [::] tuples
# specifying physical_network names usable for VLAN provider and
# tenant networks, as well as ranges of VLAN tags on each
# physical_network available for allocation as tenant networks.
#
network_vlan_ranges = physnet1:1000:2999
# Example: network_vlan_ranges = physnet1:1000:2999,physnet2

[ml2_type_gre]
# (ListOpt) Comma-separated list of : tuples enumerating range
s of GRE tunnel IDs that are available for tenant network allocation
# tunnel_id_ranges =

[ml2_type_vxlan]
# (ListOpt) Comma-separated list of : tuples enumerating
# ranges of VXLAN VNI IDs that are available for tenant network allocation.
#
# vni_ranges =

# (StrOpt) Multicast group for the VXLAN interface. When configured, will
# enable sending all broadcast traffic to this multicast group. When left
# unconfigured, will disable multicast VXLAN mode.
#
# vxlan_group =
# Example: vxlan_group = 239.1.1.1

[securitygroup]
# Controls if neutron security group is enabled or not.
# It should be false when you use nova security group.
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewal
lDriver

[ovs]
bridge_mappings = physnet1:br-eth1

3. 重启服务

     sudo service neutron-plugin-openvswitch-agent restart 

sm@computer:~$ sudo service neutron-plugin-openvswitch-agent restart
neutron-plugin-openvswitch-agent stop/waiting
neutron-plugin-openvswitch-agent start/running, process 34667

二、在控制节点上创建虚拟网络

1. 执行如下命令，创建网络

    tenantID=`keystone tenant-list | grep service | awk '{print $2}'`

    neutron net-create --tenant-id $tenantID sharednet1 --shared --provider:network_type flat --provider:physical_network physnet1 

    neutron subnet-create --tenant-id $tenantID --gateway 192.168.3.1 --dns-nameserver 192.168.3.1 --allocation-pool start=192.168.3.20,end=192.168.3.200 sharednet1 192.168.102.0/24 

注意：用户可以根据自己的情况自行设定是否需要dns，但是建议一定要给予一个连续的网段，例如192.168.3.20——192.168.3.200

    neutron net-list 

sm@controller:~$ neutron net-list
+--------------------------------------+------------+-----------------------------------------------------+
| id                                   | name       | subnets                                             |
+--------------------------------------+------------+-----------------------------------------------------+
| 1dfa9da1-43fd-4128-b9a0-2ca76a664933 | sharednet1 | db1aad02-3890-44d4-93c4-c933c2c818a5 192.168.3.0/24 |
+--------------------------------------+------------+-----------------------------------------------------+

2. 执行如下命令，添加规则     

    nova secgroup-add-rule default tcp 22 22 0.0.0.0/0

    nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0

    nova secgroup-list-rules default

三、在控制节点安装Horizon

1. 安装仪表盘服务包

     sudo apt-get install apache2 memcached libapache2-mod-wsgi openstack-dashboard

  

2. 编辑/etc/openstack-dashboard/local_settings.py文件

     [ sudo vi /etc/openstack-dashboard/local_settings.py ]

     更新设置如下：

    

       CACHES = {

           'default': {

           'BACKEND' : 'django.core.cache.backends.memcached.MemcachedCache',

           'LOCATION' : '127.0.0.1:11211'

           }

       }

      ALLOWED_HOSTS = [*]

      OPENSTACK_HOST = "192.168.3.180"

  

3. 重启服务

   sudo service apache2 restart

sm@controller:~$ sudo service apache2 restart
 * Restarting web server apache2                                                                                                                  AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 192.168.3.180. Set the 'ServerName' directive globally to suppress this message
                                                                                                                                           [ OK ]

   sudo service memcached restart

sm@controller:~$ sudo service memcached restart
Restarting memcached: memcached.

4.进入horizon界面，管理相关的云环境

用户名：admin

密码：admin4smtest

其实就是keystone创建的admin用户和密码。

至此，一个简单的OpenStack环境已经大家完毕！

我们并没有安装相关的块存储（cinder)、对象存储(swift），感兴趣的可以自行研究。
