7. 安装网络服务neutron¶

0. 介绍¶

# neutron：允许创建、附加网卡设备，这些设备由其他的openstack服务管理。
# 插件式的实现可以容纳不同的网络设备和软件，为openstack架构与部署提供了灵活性。

# 常用组件：
    neutron-server：接收和响应外部的网络管理请求
    neutron-linuxbridge-agent：负责创建桥接网卡
    neutron-dhcp-agent：负责分配IP
    neutron-metadata-agent：配合nova-metadata-api实现虚拟机的定制化操作
    L3-agent：实现三层网络vxlan（网络层）

## 1.数据库创库授权
## 2.在keystone创建系统用户关联角色
## 3.在keystone创建服务，注册api
## 4.安装相应服务软件包
## 5.修改相应服务的配置文件
## 6.同步数据库
## 7.启动服务

控制节点¶

1.数据库创库授权¶

#control
#1.登录
mysql

#2.建库
CREATE DATABASE neutron;

#3.授权
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'NEUTRON_DBPASS';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'NEUTRON_DBPASS';

#4.退出
exit

2.在keystone创建系统用户关联角色¶

# 在keystone创建系统用户(glance,nova,neutron)关联角色
openstack user create --domain default --password NEUTRON_PASS neutron

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

3.在keystone创建服务，注册api¶

#1.创建服务
openstack service create --name neutron --description "OpenStack Networking" network

#2.注册api
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

#3.查看服务
openstack service list

[root@controller ~]# openstack service list
+----------------------------------+----------+----------+
| ID                               | Name     | Type     |

| a538eedaa2364bd5904e24ed2cce0928 | keystone | identity |
+----------------------------------+----------+----------+

4.安装相应服务软件包¶

yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables -y

5.修改相应服务的配置文件¶

1. neutron.conf¶

#1.备份
cp /etc/neutron/neutron.conf{,.bak}

#2.去注释
grep '^[a-Z\[]' /etc/neutron/neutron.conf.bak >/etc/neutron/neutron.conf

#3.查看
mysql neutron -e "show tables;"

7.启动服务¶

#1.重启nova服务
systemctl restart openstack-nova-api.service

#2.开机自启neutron服务
systemctl enable neutron-server.service \
  neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
  neutron-metadata-agent.service

#3.启动neutron服务
systemctl start neutron-server.service \
  neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
  neutron-metadata-agent.service

2. linuxbridge_agent.ini¶

#1.备份
cp /etc/neutron/plugins/ml2/linuxbridge_agent.ini{,.bak}

#2.去注释
grep '^[a-Z\[]' /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak >/etc/neutron/plugins/ml2/linuxbridge_agent.ini

#3.修改
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini  linux_bridge physical_interface_mappings  provider:eth0
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini  securitygroup enable_security_group  True
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini  securitygroup firewall_driver  neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini  vxlan enable_vxlan  False

#4.校验
md5sum /etc/neutron/plugins/ml2/linuxbridge_agent.ini
# 3f474907a7f438b34563e4d3f3c29538  /etc/neutron/plugins/ml2/linuxbridge_agent.ini

#5.查看
cat -n /etc/neutron/plugins/ml2/linuxbridge_agent.ini

[root@compute1 ~]# #4.校验
[root@compute1 ~]# md5sum /etc/neutron/plugins/ml2/linuxbridge_agent.ini

3. nova.conf¶

#1.再次修改nova.conf
openstack-config --set /etc/nova/nova.conf  neutron url  http://controller:9696
openstack-config --set /etc/nova/nova.conf  neutron auth_url  http://controller:35357
openstack-config --set /etc/nova/nova.conf  neutron auth_type  password
openstack-config --set /etc/nova/nova.conf  neutron project_domain_name  default
openstack-config --set /etc/nova/nova.conf  neutron user_domain_name  default
openstack-config --set /etc/nova/nova.conf  neutron region_name  RegionOne
openstack-config --set /etc/nova/nova.conf  neutron project_name  service
openstack-config --set /etc/nova/nova.conf  neutron username  neutron
openstack-config --set /etc/nova/nova.conf  neutron password  NEUTRON_PASS

#2.校验
md5sum /etc/nova/nova.conf
# 328cd5f0745e26a420e828b0dfc2934e  /etc/nova/nova.conf

#3.查看
cat -n /etc/nova/nova.conf

3.启动¶

systemctl restart openstack-nova-compute.service
systemctl enable neutron-linuxbridge-agent.service
systemctl start neutron-linuxbridge-agent.service

4. 再次验证¶

#controller
neutron agent-list
#出现4个笑脸，则说明成功！（host列，多出一个compute1）

[root@controller ~]# neutron agent-list
