openstack-Agile Controller-DCN插件安装

一：目录

1. 下载插件包
2. 安装插件
3. 安装过程遇见的问题
4. 注意

二： 下载插件包

1. 插件包

   networking-huawei.tar.gz

2. 用下面三个文件替换目录/networking-huawei/tools下的对应文件（此处与kilo版openstack才需要替换，原因：对接K版时原脚本文件有几处问题）

   networking_huawei_config.txt

   networking_huawei_install.sh

   networking_huawei_uninstall.sh

三： 安装插件

1. 在VCF集成页面点击资料跳转到安装文档，Agile Controller-DCN插件安装文档
   

四：安装过程遇见的问题

1. python未安装urllib3模块

安装完成后点击openstack界面的网络/路由菜单，出现如下错误

Error: 无法获取外部网络"Connection to neutron failed: 
HTTPConnectionPool(host='10.15.25.201', port=9696): 
Max retries exceeded with url: /v2.0/networks.json?router%3Aexternal=True (
Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f930b287290>: Failed to establish a new connection: Errno 111] Connection refused',)):列表

或在/var/log/neutron/server.log日志中出现如下错误

2020-02-16 21:15:32.602 29265 TRACE stevedore.extension ImportError: No module named ssl_

解决方法：安装urllib3模块

pip install urllib3==1.22

2. 配置文件中未设置物理网卡名称

/etc/neutron/huawei_driver_config.ini physical_network not configured

参数在配置文件中的位置

解决方法：根据下图配置物理网卡参数

五：注意
