openstack部署之neutron

简介

   本次部署neutron组件,neutron组件主要管理openstack网络。分别部署neutron和controller neutron节点,与上一篇博客部署nova类似,controller和compute节点同样分别部署到两台设备上。

部署controller neutron

创建数据库

  与其他组件一样,首先需要创建neutron需要的数据库,操作如下:

$ mysql -u root -p

  创建neutron数据库

MariaDB [(none)] CREATE DATABASE neutron;

  授权数据库

MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \
  IDENTIFIED BY 'neutron';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \
  IDENTIFIED BY 'neutron';

组件部署

  设置环境变量

[root@localhost ~]# source admin-openstack.sh
  • 创建neutron user
$ openstack user create --domain default --password-prompt neutron

User Password:
Repeat User Password:

部署neutron compute node

memcached_servers = 192.168.46.130:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron
  •  配置锁文件路径
[oslo_concurrency]
# ...
lock_path = /var/lib/neutron/tmp

配置Provider networks

配置Linux bridge agent

  编辑/etc/neutron/plugins/ml2/linuxbridge_agent.ini文件

  • 物理网卡映射
[linux_bridge]
physical_interface_mappings = provider:ens33
  • 开启vxlan
[vxlan]
enable_vxlan = false
  • 开启安全组
[securitygroup]
# ...
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

配置计算服务

  • 在nova中增加neutron配置
[neutron]
url = http://192.168.46.130:9696
auth_url = http://192.168.46.130:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron

 最后的配置

  •  重启nova-compute服务
# systemctl restart openstack-nova-compute.service
  •  启动linux bridge agent和配置自动启动
# systemctl enable neutron-linuxbridge-agent.service
# systemctl start neutron-linuxbridge-agent.service  

验证服务

  以上配置都完成后,在controller查看服务状态,可以看到有一个Host为node2,这个就是刚才配置的neutron compute node,所有服务状态都应该为UP

[root@localhost ~]# openstack network agent list
+--------------------------------------+--------------------+-----------------------+-------------------+-------+-------+---------------------------+
| ID                                   | Agent Type         | Host                  | Availability Zone | Alive | State | Binary                    |
+--------------------------------------+--------------------+-----------------------+-------------------+-------+-------+---------------------------+

+--------------------------------------+--------------------+-----------------------+-------------------+-------+-------+---------------------------+

问题总结

1、在所有配置完成后一直不出现neutron compute node,并且查看所有日志都没有报错,经过检查发现,我的controller主机和compute主机使用的hostname都是localhost.localdomain,两台主机的hostname不能一样,虽然以上的所有配置里都是使用的两台设备的IP地址,但是主机名称可能服务底层也使用到了,以下操作修改compute node的设备hostname为node2

  • 修改/etc/hosts文件
127.0.0.1  node2
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.46.130 localhost.localdomain   #配置通过hostname连接192.168.46.130,同样192.168.46.130设备上也该配置
