一、安装计算服务
1、安装计算服务
yum install openstack-nova-compute -y
2、编辑/etc/nova/nova.conf文件并设置如下内容
[DEFAULT] enabled_apis = osapi_compute,metadata transport_url = rabbit://openstack:ADMIN_PASS@controller my_ip = 192.168.122.31 use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver ... [api] 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 = nova password = ADMIN_PASS ... [vnc] enabled = True server_listen = 0.0.0.0 server_proxyclient_address = $my_ip novncproxy_base_url = http://192.168.122.31:6080/vnc_auto.html ... [glance] api_servers = http://controller:9292 ... [oslo_concurrency] lock_path = /var/lib/nova/tmp ... [placement] os_region_name = RegionOne project_domain_name = Default project_name = service auth_type = password user_domain_name = Default auth_url = http://controller:35357/v3 username = placement password = ADMIN_PASS
3、检测当前计算节点是否支持硬件虚拟化
我使用的虚拟机，这里返回0，明显我不支持硬件虚拟化
egrep -c '(vmx|svm)' /proc/cpuinfo
0
4、编辑/etc/nova/nova.conf文件设置qemu来提供软件虚拟化
[libvirt] virt_type = qemu cpu_mode = none
5、设置服务的开机自启动，并启动计算服务
systemctl enable libvirtd.service openstack-nova-compute.service
systemctl start libvirtd.service openstack-nova-compute.service
6、（控制节点）向cell数据库添加计算节点
执行下面的命令，查看计算节点信息是否已经在数据库
openstack compute service list --service nova-compute +----+--------------+------------+------+---------+-------+----------------------------+ | ID | Binary | Host | Zone | Status | State | Updated At | +----+--------------+------------+------+---------+-------+----------------------------+ | 7 | nova-compute | controller | nova | enabled | up | 2020-07-15T04:02:00.000000 | | 8 | nova-compute | computer1 | nova | enabled | up | 2020-07-15T04:01:53.000000 | +----+--------------+------------+------+---------+-------+----------------------------+
7、（控制节点）发现计算节点
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova Found 2 cell mappings. Skipping cell0 since it does not contain hosts. Getting computes from cell 'cell1': fc354ac0-a088-4dbb-b106-e795ebeaec32 Checking host mapping for compute host 'compute': 47b0f376-fa1a-4fe8-9f2e-af1be125781a Creating host mapping for compute host 'compute': 47b0f376-fa1a-4fe8-9f2e-af1be125781a Found 1 unmapped computes in cell: fc354ac0-a088-4dbb-b106-e795ebeaec32
8、（控制节点）验证操作

二、安装网络服务
1、安装软件包
yum install openstack-neutron-linuxbridge ebtables ipset -y
2、编辑/etc/neutron/neutron.conf文件完成如下项
[DEFAULT] transport_url = rabbit://openstack:fuai123@controller 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 = fuai123 ... [oslo_concurrency] lock_path = /var/lib/neutron/tmp
3、配置linux bridge插件，编辑/etc/neutron/plugins/ml2/linuxbridge_agent.ini完成如下项
[linux_bridge] physical_interface_mappings = provider:enp0s8 #第二张网卡名 ... [vxlan] enable_vxlan = true local_ip = 192.168.122.78 l2_population = true ... [securitygroup] enable_security_group = true firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
4、确认内核支持网桥filters并作如下设置，编辑/etc/sysctl.conf增加以下内容
net.bridge.bridge-nf-call-iptables=1 net.bridge.bridge-nf-call-ip6tables=1
载入br_netfilter模块
modprobe br_netfilter
从配置文件加载内核参数
sysctl -p
配置计算服务使用网络服务/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 = ADMIN_PASS
5、完成安装，设置服务
systemctl restart openstack-nova-compute.service systemctl enable neutron-linuxbridge-agent.service systemctl start neutron-linuxbridge-agent.service
6、（控制节点）向cell数据库添加计算节点
openstack compute service list --service nova-compute 查看计算节点信息是否已经在数据库 su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova 发现计算节点
nova-status upgrade check 确认cells和placement api成功运行
7、（控制节点）验证操作
执行命令验证是否成功启动neutron-server
openstack extension list --network
执行命令列出插件，验证网络插件是否成功启动
