九、【openstack train安装】第八步-计算节点安装nova、neutron组件

前置部署：请确保前面文章提到的部署前准备工作已经在计算节点完成

1、安装nova、neutron组件
[root@compute1 ~]# yum install openstack-nova-compute openstack-neutron-linuxbridge ebtables ipset -y
[root@compute1 ~]# vi /etc/nova/nova.conf
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:123456@controller
my_ip = 本计算节点ip
use_neutron = true
firewall_driver = nova.virt.firewall.NoopFirewallDriver
vif_plugging_is_fatal = false
vif_plugging_timeout = 0

[root@compute1 ~]# egrep -c '(vmx|svm)' /proc/cpuinfo
如果此命令返回值不是0，则计算节点支持硬件加速，不需要加入下面的配置。 如果此命令返回值是0，则计算节点不支持硬件加速，并且必须配置libvirt为使用QEMU而不是KVM，需要编辑/etc/nova/nova.conf 文件中的[libvirt]部分： 
[libvirt] 
virt_type = qemu

[root@compute1 ~]# vi /etc/neutron/neutron.conf
[DEFAULT]
auth_strategy = keystone
transport_url = rabbit://openstack:123456@controller
[cors]
[database]
[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default

[oslo_messaging_notifications]
[oslo_messaging_rabbit]

[root@compute1 ~]# vi /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[DEFAULT]
[linux_bridge]
physical_interface_mappings = provider:eno3 #启用的网卡名字
[vxlan]
enable_vxlan = true
local_ip = 本计算节点ip
l2_population = true
[securitygroup]
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

[root@compute1 ~]# systemctl enable libvirtd.service openstack-nova-compute.service neutron-linuxbridge-agent.service
[root@compute1 ~]# systemctl start libvirtd.service openstack-nova-compute.service neutron-linuxbridge-agent.service
2、验证
在控制节点进行
[root@controller ~]# . admin-openrc 
[root@controller ~]# openstack compute service list --service nova-compute

如果控制短点没有开启自动发现节点，需要执行下面指令进行同步
[root@controller ~]# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

[root@controller ~]# openstack network agent list

需要新部署计算节点主机名在host列表

到此已经完成部署，可以使用了
