[root@controller ~]# systemctl status \
openstack-nova-api.service \
openstack-nova-scheduler.service \
openstack-nova-conductor.service \
openstack-nova-novncproxy.service三、安装配置组件（计算节点）
1.配置OpenStack yum源文件
[root@computer ~]# cat >>/etc/yum.repos.d/openstack.repo<<EOF
[openstack-train]
name=openstack-train
baseurl=https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-train/

gpgcheck=1
EOF2.安装软件包
[root@computer ~]# yum install openstack-nova-compute -y3.编辑配置文件
①.备份配置文件并删除其中的空余部分
②.编辑配置文件/etc/nova/nova.conf
[root@computer ~]# cd /etc/nova/ && cp nova.conf nova.conf.source && cat nova.conf.source | grep -Ev "^#|^$" > nova.conf
[root@computer nova]# vim nova.conf
#启用计算和元数据API(配置密码"123456")、配置IP地址、启用对网络服务的支持

1.获取admin凭据以访问OpenStack cli
[root@controller ~]# . admin-openrc.sh2.然后确认数据库中存在计算主机
[root@controller ~]# openstack compute service list --service nova-compute
+----+--------------+----------+------+---------+-------+----------------------------+
| ID | Binary | Host | Zone | Status | State | Updated At |
+----+--------------+----------+------+---------+-------+----------------------------+
| 16 | nova-compute | computer | nova | enabled | up | 2022-07-21T17:50:08.000000 |
+----+--------------+----------+------+---------+-------+----------------------------+3.发现计算主机
[root@controller ~]# 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': 8b9f801a-9115-4b82-aa54-7f6ac661c833
Checking host mapping for compute host 'computer': 6b733901-e714-453c-880d-d578b0452c9a
Creating host mapping for compute host 'computer': 6b733901-e714-453c-880d-d578b0452c9a
Found 1 unmapped computes in cell: 8b9f801a-9115-4b82-aa54-7f6ac661c833五、验证
以下操作在控制节点实施
