1.Controller node安装Compute service
1.1 安装前准备
1.1.1 数据库配置
1.创建 nova_api, nova, nova_cell0, placement数据库
mysql CREATE DATABASE nova_api; CREATE DATABASE nova; CREATE DATABASE nova_cell0; CREATE DATABASE placement;
2.为上述数据库创建用户及授权
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS'; GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS'; GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS'; GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS'; GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY 'PLACEMENT_DBPASS'; GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY 'PLACEMENT_DBPASS';

1.2.5 创建一个名为cell1的cell
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
1.2.6 迁移nova数据库
su -s /bin/sh -c "nova-manage db sync" nova
1.2.7 确认cell0和cell1是否已注册成功

1.2.8 重启全部服务使配置生效
service nova-api restart service nova-scheduler restart service nova-conductor restart service nova-novncproxy restart
2. Compute node安装Compute service
2.1安装与设置
2.1.1 安装所需软件包
apt install nova-compute
2.1.2 修改/etc/nova/nova.conf
1.修改RabbitMQ 配置，RABBIT_PASS替换成自己的
[DEFAULT] # ... transport_url = rabbit://openstack:RABBIT_PASS@controller
2.修改api和身份认证，NOVA_PASS替换成之前设置的
[api] # ... auth_strategy = keystone [keystone_authtoken] # ... auth_url = http://controller:5000/v3 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = NOVA_PASS
3.修改my_ip ，这个MANAGEMENT_INTERFACE_IP_ADDRESS要替换成这台compute节点在管理网络中的ip地址，本次搭建中使用的地址为10.0.0.31。
[DEFAULT] # ... my_ip = MANAGEMENT_INTERFACE_IP_ADDRESS
4.开启network service支持
[DEFAULT] # ... use_neutron = true firewall_driver = nova.virt.firewall.NoopFirewallDriver
5.配置vnc
[vnc] # ... enabled = true server_listen = 0.0.0.0 server_proxyclient_address = $my_ip novncproxy_base_url = http://controller:6080/vnc_auto.html
6.配置glance api
[glance] # ... api_servers = http://controller:9292
7.配置oslo_concurrency的lock path
[oslo_concurrency] # ... lock_path = /var/lib/nova/tmp
8.删除[DEFAULT]节中的log_dir 9.设置placement认证
[placement] # ... region_name = RegionOne project_domain_name = Default project_name = service auth_type = password user_domain_name = Default auth_url = http://controller:5000/v3 username = placement password = PLACEMENT_PASS
2.2 确认安装
1.在compute节点上使用如下命令
egrep -c '(vmx|svm)' /proc/cpuinfo
如果返回结果不是0那么说明你的计算节点cpu支持硬件加速，如果返回结果是0，如下，那么需要额外配置。
root@ubuntu-ComputeNode:/home/ubuntu# egrep -c '(vmx|svm)' /proc/cpuinfo 0 root@ubuntu-ComputeNode:/home/ubuntu#
修改/etc/nova/nova-compute.conf
[libvirt] # ... virt_type = qemu
2.重启服务
service nova-compute restart
3.将计算节点添加到cell数据库中
以下操作均在controller node上执行
1.导入环境变量,确认一下compute节点是否在数据库里
root@ubuntu-ControllerNode:/home/ubuntu# . admin.opensrc root@ubuntu-ControllerNode:/home/ubuntu# openstack compute service list --service nova-compute +----+--------------+--------------------+------+---------+-------+----------------------------+ | ID | Binary | Host | Zone | Status | State | Updated At | +----+--------------+--------------------+------+---------+-------+----------------------------+ | 5 | nova-compute | ubuntu-ComputeNode | nova | enabled | up | 2019-01-10T03:40:20.000000 | +----+--------------+--------------------+------+---------+-------+----------------------------+
2.发现计算节点
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
注：这个操作需要在每次添加计算节点后都执行一次。如果觉得麻烦也可以在/etc/nova/nova.conf中添加自动扫描：
[scheduler] discover_hosts_in_cells_interval = 300
