openstack neutron 源码安装
- 使用vsphere创建虚拟机，配置如下
16U20G1NIC100G
- 使用datastorg4下的/centos-hygon.iso镜像
全部使用默认配置安装，账号密码为root/123456
- 安装完成，登陆系统后修改网卡，网盘配置如下，红色为需要修改的配置

安装python
1、安装EPEL：
sudo yum -y install epel-release
2、安装IUS软件源：
sudo yum -y install https://centos7.iuscommunity.org/ius-release.rpm
3、安装Python3.6：
sudo yum -y install python36u
创建软链接
ln -s /usr/bin/python3.6 /usr/bin/python3
4、安装pip3：
sudo yum -y install python-pip
升级pip
pip install --upgrade pip
安装基础包
yum -y groupinstall "Development tools"
yum install -y python-devel
安装openvswitch
wget https://mirrors.aliyun.com/centos/7.6.1810/cloud/x86_64/openstack-ocata/openvswitch-2.9.0-3.el7.x86_64.rpm
rpm -ivh openvswitch-2.9.0-3.el7.x86_64.rpm
如果缺少包，安装环境依赖，如下，如不缺少正常安装成功，可不安装
yum -y install wget gcc make python-devel openssl-devel kernel-devel graphviz kernel-debug-devel autoconf automake rpm-build redhat-rpm-config libtool
systemctl start openvswitch
ovs-vsctl show
显示版本号则安装成功
e49e2c77-036e-4de2-896c-00d71a8d654f
ovs_version: "2.9.0"
安装git
yum install -y git
下载neutron源码，切换到4.3分支
cd /opt/
git clone http://10.0.38.187/Cloudview_OVM/neutron.git
git branch -a
选择4.3分支
git checkout remotes/origin/4.3-master
在/opt/neutron下安装neutron依赖
pip install -r requirements.txt
如果下载中断报错，继续执行即可
修改setup.cfg
data_files =
/etc/neutron =
etc/api-paste.ini
etc/dhcp_agent.ini
etc/l3_agent.ini
etc/metadata_agent.ini
etc/metering_agent.ini

etc/rootwrap.conf
/etc/neutron/rootwrap.d =

将etc目录替换
etc文件在附件，可联系我免费下载
安装neutron
python setup.py install
修改neutron.conf配置文件
vim /etc/nova/nova.conf
[DEFAULT]
transport_url = rabbit://openstack:123456@controller
auth_strategy = keystone
[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = 123456
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
修改 openvswitch-agent.ini文件
vim /opt/neutron/etc/neutron/plugins/ml2/openvswitch_agent.ini
[agent]
tunnel_types=vxlan
l2_population=True
prevent_arp_spoofing=True
[ovs]
local_ip=10.0.36.12
bridge_mappings=inflat:br-eth2
[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
enable_ipset = true
注意：安全组要修改成ovs的，不然默认使用linuxbridge
修改 nova.conf文件
vim /etc/nova/nova.conf
[neutron]
url = http://10.0.36.3:9696
auth_url = http://10.0.36.3:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = 123456
创建网桥
ovs-vsctl add-br br-eth2
br-eth2和neutron配置的网桥名称一致
通过vsphere添加一块网卡
将网桥br-eth2和新的网盘绑定
ovs-vsctl add-port br-eth2 ens192
重启conpute服务
systemctl restart openstack-nova-compute.service
设置开机启动并启动openswitch
systemctl enable neutron-linuxbridge-agent.service
systemctl start neutron-linuxbridge-agent.service
