Networking service

Prerequisites

  1. To create the database, complete these steps:

Use the databaseaccess client to connect to the database server as the root user:

mysql -u root -p

Create the neutron database:

mysql> CREATE DATABASE neutron;

Grant properaccess to the neutron database,replacing NEUTRON_DBPASS with a suitablepassword:

mysql> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \
  IDENTIFIED BY 'NEUTRON_DBPASS';
mysql> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \
  IDENTIFIED BY 'NEUTRON_DBPASS';

  1. To create the service credentials, completethese steps:

Create the neutron user:

openstack user create --domain default --password-prompt neutron

密码：neutron

Add the admin role to the neutron user:

openstack role add --project service --user neutron admin

Create the neutron service entity:

$ openstack service create --name neutron \
  --description "OpenStack Networking" network

  1. Create the Networking service API endpoints:

openstack endpoint create --region RegionOne \
  network public http://controller:9696

openstack endpoint create --region RegionOne \
  network internal http://controller:9696

openstack endpoint create --region RegionOne \
  network admin http://controller:9696

Finalize installation

Restart the Compute service:

systemctl restartopenstack-nova-compute.service

Start the Linux bridge agent andconfigure it to start when the system boots:

# systemctl enable neutron-linuxbridge-agent.service

# systemctl start neutron-linuxbridge-agent.service

  1. The Networkingservice initialization scripts expect a symbolic link /etc/neutron/plugin.ini pointing to the ML2 plug-in configuration file, /etc/neutron/plugins/ml2/ml2_conf.ini. If thissymbolic link does not exist, create it using the following command:

ln -s /etc/neutron/plugins/ml2/ml2_conf.ini/etc/neutron/plugin.ini

  1. Populate thedatabase:

su -s /bin/sh -c "neutron-db-manage --config-file/etc/neutron/neutron.conf \

  --config-file/etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron

  1. Restart theCompute API service:

systemctl restart openstack-nova-api.service

  1. Start the Networking services andconfigure them to start when the system boots.

    For both networking options:

# systemctl enable neutron-server.service \

 neutron-linuxbridge-agent.service neutron-dhcp-agent.service \

 neutron-metadata-agent.service

# systemctl start neutron-server.service \

 neutron-linuxbridge-agent.service neutron-dhcp-agent.service \

 neutron-metadata-agent.service

For networking option 2, also enable and start the layer-3service:

# systemctl enable neutron-l3-agent.service

# systemctl start neutron-l3-agent.service

验证网络配置：

the dashboard on the controller node

yum install openstack-dashboard

1. Edit the /etc/openstack-dashboard/local_settings file and complete the followingactions:

  • Configure the dashboard to useOpenStack services on the controller node:

·        OPENSTACK_HOST="controller"

  • Allow all hoststo access the dashboard:

·        ALLOWED_HOSTS=['*', ]

  • Configure the memcached session storageservice:

·        SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

·         

·        CACHES = {

·            'default': {

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

·                 'LOCATION':'controller:11211',

·            }

·        }

  • Enable theIdentity API version 3:

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

  • Enable supportfor domains:

·        OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT=True

  • Configure APIversions:

·        OPENSTACK_API_VERSIONS = {

·            "identity": 3,

·            "p_w_picpath": 2,

·            "volume": 2,

·        }

  • Configure default as the defaultdomain for users that you create via the dashboard:

·        OPENSTACK_KEYSTONE_DEFAULT_DOMAIN="default"

 

  • Configure user as the defaultrole for users that you create via the dashboard:

·        OPENSTACK_KEYSTONE_DEFAULT_ROLE="user"

  • If you chosenetworking option 1, disable support for layer-3 networking services:

·        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,

·        }

  • Optionally,configure the time zone:

·        TIME_ZONE="TIME_ZONE"

Finalize installation

systemctl restart httpd.servicememcached.service

 

OK，安装完成可以使用啦

 

刚开始进入的时候先创建网络


网络创建完毕后创建云主机类型


Ok可以创建虚拟机啦


由于做的比较简单当下一步到网络的时候就可以直接点击创建云主机啦


OK大功告成。

附上官方文档地址：centos7，linux系统可自行选择。
