OpenStack安装笔记五

今天应该是配置网络部分Networking Service，参考官方文档
当前版本 neutron 11.0.7.dev44

配置Controller端
配置provider interface 接口ifcfg-eno2和名称解析

配置Compute Node端，也是网络端口配置和名称解析，新创建了一个ifcfg-enp0a1,内容如下，UUID是拷贝原有的内容

DEVICE=enp0a1
TYPE=Ethernet
ONBOOT="yes"
BOOTPROTO="none"
UUID=1bb944cc-d2f0-46c7-9f2d-de9db994a81a

重新启动network服务失败，按照文档重新启动电脑，原有接口可以正常连接，这可好（之前修改网络配置后服务启动失败，导致ssh无法连接，可怕😱）。只是也未看见新增接口的状态，待查

配置好后，然后就是验证各网络连接状态，controller与compute node是否可以ping通，与外网是否可以ping通，这些准备好后，再进入下面的步骤

Install and configure controller node

创建MySQL数据库，用户及授权，注意修改NEUTRON_DBPASS

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

创建API

openstack user create --domain default --password-prompt neutron
openstack role add --project service --user neutron admin
openstack service create --name neutron --description "OpenStack Networking" network
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

Configure networking options
之前选择的网络结构就是Provider networks，所以按下面的文档进行

• Networking Option 1: Provider networks

安装完需要的软件包

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

参照文档修改几个配置文件

• /etc/neutron/neutron.conf
• /etc/neutron/plugins/ml2/ml2_conf.ini
• /etc/neutron/plugins/ml2/linuxbridge_agent.ini
• /etc/neutron/dhcp_agent.ini

返回到Networking controller node configuration页面，继续修改配置文件

• /etc/neutron/metadata_agent.ini
• /etc/nova/nova.conf

配置computo service 使用网络服务
创建链接

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

修改数据库

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

重新启动服务

systemctl restart openstack-nova-api.service

设置服务自启动及开启服务

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

systemctl enable neutron-l3-agent.service

systemctl start neutron-l3-agent.service

controller node 配置完毕

Install and configure compute node

安装软件包

# yum install openstack-neutron-linuxbridge ebtables ipset

修改配置文件

• /etc/neutron/neutron.conf
• /etc/neutron/plugins/ml2/linuxbridge_agent.ini
• /etc/nova/nova.conf

重新启动Compute service

# systemctl restart openstack-nova-compute.service

设置开机启动及开启服务

# systemctl enable neutron-linuxbridge-agent.service
# systemctl start neutron-linuxbridge-agent.service

操作完毕，只是没有看到有验证环节，之前的服务安装后都有一个验证的步骤，可以检查是否已安装成功了
