openstack-rocky简化版安装：https://blog.51cto.com/u_14814545/5169584
接着上次，[openstack-rocky简化版安装]基础上，进行openstack实例的创建
官方文档的参考:https://docs.openstack.org/install-guide/launch-instance.html
1.创建网络
官方参考:https://docs.openstack.org/install-guide/launch-instance-networks-provider.html
提供者网络（桥接）
网段需要和宿主机是同一个网段
source
#网络
[root@control1 ~]# openstack network create --share --external \
--provider-physical-network external \
--provider-network-type flat external-net

2.实例类型
openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano
遇到如下问题
解决办法:启动nova服务
systemctl start openstack-nova-api.service \
openstack-nova-consoleauth openstack-nova-scheduler.service \
openstack-nova-conductor.service openstack-nova-novncproxy.service
3.生成一个键值对（可有可无）
[root@control1 ~]# source
[root@control1 ~]# ssh-keygen -q -N ""
Enter file in which to save the key (/root/.ssh/id_rsa):
[root@control1 ~]# openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey #~ 代表当前账号
[root@control1 ~]# openstack keypair list #验证
4.创建安全组
source
openstack security group rule create --proto icmp default
openstack security group rule create --proto tcp --dst-port 22 default
5.创建虚拟机
官网参考:https://docs.openstack.org/install-guide/launch-instance-provider.html
source
启动一台实例，您必须至少指定一个类型、镜像名称、网络、安全组、密钥和实例名称
#列出可用类型：
openstack flavor list #您也可以以 ID 引用类型
#列出可用镜像
openstack image list
#列出可用网络：
openstack network list #你必须使用ID而不是名称才可以使用这个网络
#列出可用的安全组
openstack security group list
#密钥
openstack keypair list
#用demo账号
openstack server create --flavor m1.nano --image cirros-0.3.5 \
--nic net-id=c370edca-7740-4b9a-bf54-b01ec6ab2530 --security-group default \
--key-name mykey linux47-vm1
创建出现以下错误
openstack server list
错误排查
grep 'ERROR' /var/log/nova/*
grep 'ERROR' /var/log/neutron/*
grep 'ERROR' /var/log/glance/*
grep 'ERROR' /var/log/keystone/*
rm -f /var/log/nova/* && rm -f /var/log/neutron/* && rm -f /var/log/glance/*
创建成功
获取登录虚拟机链接
[root@control1 ~]# openstack console url show linux47-vm1
+-------+----------------------------------------------------------------------------------------------+
| Field | Value |
+-------+----------------------------------------------------------------------------------------------+
| type | novnc |
| url | http://192.168.47.23:6080/vnc_auto.html?path=%3Ftoken%3De7cadc57-7cb0-48b0-ba51-60a46dae2f67 |
+-------+----------------------------------------------------------------------------------------------+
启动虚拟机
遇到问题
计算节点提示如下错误
虚拟机进入不了
