Posted 2021-01-23 yypr

 ###openstack-ocata 单节点安装 部署 目录汇总

 

 

一 安装neutron

yum install openstack-neutron-linuxbridge ebtables ipset -y

--------------------------------------------------------------------------------
二 配置neutron文件

cp /etc/neutron/neutron.conf /etc/neutron/neutron.conf.bak
> /etc/neutron/neutron.conf

echo ‘
[DEFAULT]
# ...
transport_url = rabbit://openstack:[email protected]
auth_strategy = keystone

[keystone_authtoken]
# ...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron

[oslo_concurrency]
# ...
lock_path = /var/lib/neutron/tmp
‘>>/etc/neutron/neutron.conf

--------------------------------------------------------------------------------
三 配置自助网络文件
cp /etc/neutron/plugins/ml2/linuxbridge_agent.ini /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak
> /etc/neutron/plugins/ml2/linuxbridge_agent.ini

##修改provider local_ip.
echo ‘
[linux_bridge]
physical_interface_mappings = provider:ens33

[vxlan]
enable_vxlan = true
local_ip = OVERLAY_INTERFACE_IP_ADDRESS
l2_population = true

[securitygroup]
# ...
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
‘>>/etc/neutron/plugins/ml2/linuxbridge_agent.ini

--------------------------------------------------------------------------------
四 配置nova文件

vim /etc/nova/nova.conf

[neutron]
# ...
url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron

--------------------------------------------------------------------------------
五 重启nova 启动neutron服务

systemctl restart openstack-nova-compute.service

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

六 在控制节点执行验证操作

openstack network agent list
