openstack O版 配置compute节点 nova 和 Neutron安装

1. 配置nova.conf
   [root@compute ~]# yum install openstack-selinux python-openstackclient yum-plugin-priorities openstack-nova-compute openstack-utils ntpdate -y
   [root@compute ~]# cp /etc/nova/nova.conf /etc/nova/nova.conf.bak
   [root@compute ~]# >/etc/nova/nova.conf
   [DEFAULT]
   auth_strategy = keystone
   my_ip = 192.168.0.112
   use_neutron = True
   firewall_driver = nova.virt.firewall.NoopFirewallDriver
   transport_url = rabbit://openstack:devops@controller
   [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 = nova
   password = devops
   [placement]
   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 = placement
   password = devops
   os_region_name = RegionOne
   [vnc]
   enabled = True
   keymap = en-us
   vncserver_listen = 0.0.0.0
   vncserver_proxyclient_address = 192.168.0.112
   novncproxy_base_url = http://192.168.0.111:6080/vnc_auto.html
   [glance]
   api_servers = http://controller:9292
   [oslo_concurrency]
   lock_path = /var/lib/nova/tmp
   [libvirt]
   virt_type = qemu
2. 设置libvirtd.service 和openstack-nova-compute.service开机启动
   [root@compute ~]# systemctl enable libvirtd.service openstack-nova-compute.service
   [root@compute ~]# systemctl restart libvirtd.service openstack-nova-compute.service
   [root@compute ~]# systemctl status libvirtd.service openstack-nova-compute.service
3. 到controller上执行验证
   [root@controller ~]# source admin-openrc
   [root@controller ~]# openstack compute service list
   
   二、安装Neutron
4. 安装相关软件包
   [root@compute ~]# yum install openstack-neutron-linuxbridge ebtables ipset -y
   [root@compute ~]# cp /etc/neutron/neutron.conf /etc/neutron/neutron.conf.bak
   [root@compute ~]# >/etc/neutron/neutron.conf
   [DEFAULT]
   auth_strategy = keystone
   advertise_mtu = True
   dhcp_agents_per_network = 2
   control_exchange = neutron
   nova_url = http://controller:8774/v2
   transport_url = rabbit://openstack:devops@controller
   [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 = devops
   [oslo_concurrency]
   lock_path = /var/lib/neutron/tmp
5. 配置/etc/neutron/plugins/ml2/linuxbridge_agent.ini
   [root@compute ~]# cat /etc/neutron/plugins/ml2/linuxbridge_agent.ini | grep -v "^#" | grep -v "^$"
   [DEFAULT]
   [agent]
   [linux_bridge]
   physical_interface_mappings = provider:ens33
   [securitygroup]
   enable_security_group = True
   firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
   [vxlan]
   enable_vxlan = True
   local_ip = 192.168.0.112
   l2_population = True
6. 配置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 = nova
   password = devops
7. 重启和enable相关服务
   [root@compute ~]# systemctl restart libvirtd.service openstack-nova-compute.service
   [root@compute ~]# systemctl enable neutron-linuxbridge-agent.service
   [root@compute ~]# systemctl restart neutron-linuxbridge-agent.service
   [root@compute ~]# systemctl status libvirtd.service openstack-nova-compute.service neutron-linuxbridge-agent.service
   三．在controler上执行验证
   [root@controller ~]# source admin-openrc
   [root@controller ~]# neutron agent-list
   
   [root@controller ~]# nova host-list
