本操作通常在计算节点上完成，除非是all in one
一. 安装nova-kvm软件包
root@compute:~# apt-get -y install nova-compute-kvm
二. 修改nova配置文件
# 由于官方配置文件修改较为麻烦，这里直接创建一个新的配置文件
root@compute:~# mv /etc/nova/nova.conf /etc/nova/nova.conf.org
root@compute:~# vim /etc/nova/nova.conf
[DEFAULT]
# 设置计算节点IP
my_ip = 192.168.0.30
state_path = /var/lib/nova
enabled_apis = osapi_compute,metadata
log_dir = /var/log/nova
# 消息队列连接设置
transport_url = rabbit://openstack:root@controller
[api]
auth_strategy = keystone
# 启用VNC
[vnc]
enabled = True
server_listen = 0.0.0.0
server_proxyclient_address = $my_ip
novncproxy_base_url = http://controller:6080/vnc_auto.html
# Glance连接设置
[glance]
api_servers = http://controller:9292
[oslo_concurrency]
lock_path = $state_path/tmp
# Keystone连接设置
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = root
# Placement连接设置，所有节点的配置必须相同，否则会出现错误
[placement]
auth_url = http://controller:5000
os_region_name = RegionOne
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = placement
password = root
[wsgi]
api_paste_config = /etc/nova/api-paste.ini
# 设置计算节点IP
my_ip = 192.168.0.30
state_path = /var/lib/nova
enabled_apis = osapi_compute,metadata
log_dir = /var/log/nova
# 消息队列连接设置
transport_url = rabbit://openstack:root@controller
[api]
auth_strategy = keystone
# 启用VNC
[vnc]
enabled = True
server_listen = 0.0.0.0
server_proxyclient_address = $my_ip
novncproxy_base_url = http://controller:6080/vnc_auto.html
# Glance连接设置
[glance]
api_servers = http://controller:9292
[oslo_concurrency]
lock_path = $state_path/tmp

memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = root
# Placement连接设置，所有节点的配置必须相同，否则会出现错误
[placement]
auth_url = http://controller:5000
os_region_name = RegionOne
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = placement
password = root
[wsgi]
api_paste_config = /etc/nova/api-paste.ini
# 因为配置文件是新建的，这里把权限加回去
root@compute:~# chmod 640 /etc/nova/nova.conf
root@compute:~# chgrp nova /etc/nova/nova.conf
root@compute:~# systemctl restart nova-compute
三. 检查虚拟化开启状态
# 检查虚拟化是否开启，如返回非0则为开启
root@compute:~# egrep -c '(vmx|svm)' /proc/cpuinfo
1
⚠ 如果上面命令执行结果不为0，则跳过这一步，如果为0，则需要执行下面这一步
root@compute:~# vim /etc/nova/nova-compute.conf
# 找到[libvirt]这一项，将其中的virt_type修改为以下样式，没有这一项则手动添加
[libvirt]
virt_type = qemu
四. 同步数据库并查看服务列表
# 注意本操作在控制节点上运行
root@controller:~# su -s /bin/bash nova -c "nova-manage cell_v2 discover_hosts"
# 查看nova服务状态
root@controller:~# openstack compute service list
