openstack之neutron

网络组件neutron在整个openstack体系中应该是最难的一部分,需要在控制节点和计算节点上面同时安装


1、创建neutron用户及授权

[root@controller ~]# source admin-openrc.sh
[root@controller ~]# openstack user create --domain default --password=neutron neutron

| service_type | network                          |
| url          | http://172.16.80.130:9696        |
+--------------+----------------------------------+

3、安装配置neutron

[root@controller ~]# yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge python-neutronclient ebtables ipset -y

[root@controller neutron]# grep -n "^[a-Z]" /etc/neutron/neutron.conf
3:verbose = True
20:state_path = /var/lib/neutron
60:core_plugin = ml2

723:auth_url = http://172.16.80.130:35357
724:auth_plugin = password
725:project_domain_id = default
726:user_domain_id = default
727:project_name = service
728:username = neutron
729:password = neutron
744:connection = mysql://neutron:neutron@172.16.80.130:3306/neutron
788:auth_url = http://172.16.80.130:35357
789:auth_plugin = password
790:project_domain_id = default

792:region_name = RegionOne
793:project_name = service
794:username = nova
795:password = nova
831:lock_path = $state_path/lock
970:rabbit_host = 172.16.80.130
971:rabbit_port = 5672
972:rabbit_userid = openstack
973:rabbit_password = openstack

修改ml2配置文件
[root@controller ml2]# grep -n "^[a-Z]" /etc/neutron/plugins/ml2/ml2_conf.ini 
5:type_drivers = flat,vlan,gre,vxlan,geneve
13:tenant_network_types = flat,vlan,gre,vxlan,geneve
18:mechanism_drivers = openvswitch,linuxbridge
27:extension_drivers = port_security
67:flat_networks = physnet1
120:enable_ipset = True

修改linuxbriage配置文件
[root@controller ml2]# grep -n "^[a-Z]" /etc/neutron/plugins/ml2/linuxbridge_agent.ini 
3:linux_bridge]
12:physical_interface_mappings = physnet1:eno16777736
18:enable_vxlan = false
64:firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
68:enable_security_group = True

修改dhcp配置文件
[root@controller neutron]# grep -n "^[a-Z]" /etc/neutron/dhcp_agent.ini
14:interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
37:dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq 
60:enable_isolated_metadata = true


修改配置metadata_agent.ini
[root@controller neutron]# grep -n "^[a-Z]" /etc/neutron/metadata_agent.ini 
5:verbose = True
6:auth_uri = http://172.16.80.130:5000
7:auth_url = http://172.16.80.130:35357
8:auth_region = RegionOne
9:auth_plugin = password
10:project_domain_id = default
11:user_domain_id = default
12:project_name = service
13:username = neutron
14:password = neutron
15:nova_metadata_ip = 172.16.80.130
16:metadata_proxy_shared_secret = neutron


4、在控制节点的nova中添加关于neutron的配置

[neutron]

url = http://172.16.80.130:9696
auth_url = http://172.16.80.130:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron
service_metadata_proxy = True
metadata_proxy_shared_secret = neutron

[root@controller neutron]# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini


5、导入数据库并检查结果

[root@controller neutron]# 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
[root@controller neutron]# mysql -e "use neutron;show tables;"

6、重启nova-api,并启动neutron服务

[root@controller neutron]# systemctl restart openstack-nova-api
[root@controller neutron]# systemctl enable neutron-server.service   neutron-linuxbridge-agent.service neutron-dhcp-agent.service   neutron-metadata-agent.service
Created symlink from /etc/systemd/system/multi-user.target.wants/neutron-server.service to /usr/lib/systemd/system/neutron-server.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/neutron-linuxbridge-agent.service to /usr/lib/systemd/system/neutron-linuxbridge-agent.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/neutron-dhcp-agent.service to /usr/lib/systemd/system/neutron-dhcp-agent.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/neutron-metadata-agent.service to /usr/lib/systemd/system/neutron-metadata-agent.service.
[root@controller neutron]# systemctl start neutron-server.service   neutron-linuxbridge-agent.service neutron-dhcp-agent.service   neutron-metadata-agent.service


7、检查结果

[root@controller neutron]# neutron agent-list
+--------------------------------------+--------------------+------------+-------+----------------+---------------------------+
| id                                   | agent_type         | host       | alive | admin_state_up | binary                    |
+--------------------------------------+--------------------+------------+-------+----------------+---------------------------+
| 4f0ef1a2-85a6-4d6c-874c-51e139a41a8a | Metadata agent     | controller | :-)   | True           | neutron-metadata-agent    |
| 89ec6936-111c-4416-9c70-ef50ad8c2ae3 | DHCP agent         | controller | :-)   | True           | neutron-dhcp-agent        |
| d438159e-d277-411f-9f64-edda90ce383d | Linux bridge agent | controller | :-)   | True           | neutron-linuxbridge-agent |
+--------------------------------------+--------------------+------------+-------+----------------+---------------------------+

8、安装部署计算节点上面的neutron服务

[root@computer1 ~]# yum install openstack-neutron openstack-neutron-linuxbridge ebtables ipset -y

直接从控制节点复制过去,无需更改
[root@controller neutron]# scp /etc/neutron/neutron.conf 172.16.80.131:/etc/neutron/
neutron.conf                                                                                                                                           100%   36KB  35.9KB/s   00:00    
[root@controller neutron]# scp /etc/neutron/plugins/ml2/linuxbridge_agent.ini 172.16.80.131:/etc/neutron/plugins/ml2/
linuxbridge_agent.ini

9、配置计算节点的nova

[neutron]

url = http://172.16.80.130:9696
auth_url = http://172.16.80.130:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron
service_metadata_proxy = True
metadata_proxy_shared_secret = neutron

10、启动服务

[root@computer1 ml2]# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
[root@computer1 ml2]# systemctl restart openstack-nova-compute.service
[root@computer1 ml2]# systemctl enable neutron-linuxbridge-agent.service
Created symlink from /etc/systemd/system/multi-user.target.wants/neutron-linuxbridge-agent.service to /usr/lib/systemd/system/neutron-linuxbridge-agent.service.
[root@computer1 ml2]# systemctl start neutron-linuxbridge-agent.service


11、在控制节点验证

[root@controller neutron]# neutron agent-list
+--------------------------------------+--------------------+------------+-------+----------------+---------------------------+
| id                                   | agent_type         | host       | alive | admin_state_up | binary                    |
+--------------------------------------+--------------------+------------+-------+----------------+---------------------------+
| 0f96e7fb-d369-451f-bd3d-6c0900c97a79 | Linux bridge agent | computer1  | :-)   | True           | neutron-linuxbridge-agent |
| 4f0ef1a2-85a6-4d6c-874c-51e139a41a8a | Metadata agent     | controller | :-)   | True           | neutron-metadata-agent    |
| 89ec6936-111c-4416-9c70-ef50ad8c2ae3 | DHCP agent         | controller | :-)   | True           | neutron-dhcp-agent        |
| d438159e-d277-411f-9f64-edda90ce383d | Linux bridge agent | controller | :-)   | True           | neutron-linuxbridge-agent |
+--------------------------------------+--------------------+------------+-------+----------------+---------------------------+
