利用iso 在OpenStack安装系统

利用iso 在OpenStack安装系统

1，上传iso镜像

(venv) [root@emporerlinux ~]# openstack image  create   --disk-format iso --container-format bare --file CentOS-7-x86_64-Minimal-2207-02.iso   testiso

2，创建一个空卷

(venv) [root@emporerlinux ~]# openstack volume  create   --size 10 testvolume  --boottble

如果忘记加这个参数：

openstack volume set --property bootable=true   testvolume<ID>
(venv) [root@emporerlinux ~]# openstack volume set --property bootable=true   testvolume

3，创建虚拟机

(venv) [root@emporerlinux ~]# openstack server create  --flavor  C2-M2-D20  --nic net-id=c40922cd-23ac-4802-bf2e-53ea42c617fd  --image testiso emporer

4，空卷关联实例机器

(venv) [root@emporerlinux ~]# openstack server add volume  emporer testvolume  --device /dev/vda

5，虚拟控制台安装

选择对应的/dev/vda 系统盘

6，安装完毕关闭虚拟机

(venv) [root@emporerlinux ~]# openstack server stop emporer

7，删除虚拟机

openstack server delete INSTANCE_NAME
(venv) [root@emporerlinux ~]# openstack server delete emporer

8，删除虚拟机卷还存在，利用卷新建虚拟机

(venv) [root@emporerlinux ~]#  openstack volume show testvolume

9，利用卷新建镜像《镜像需要active，如果镜像很大需要有一个过程queued----saving----active》

(venv) [root@emporerlinux ~]# openstack image create  --volume  testvolume  test-image

10，利用新建镜像启动虚拟机

(venv) [root@emporerlinux ~]#    openstack server create  --flavor  C2-M2-D20  --nic net-id=c40922cd-23ac-4802-bf2e-53ea42c617fd  --image  test-image     emporer

11，连接测试

(venv) [root@emporerlinux ~]# ssh root@192.168.10.52
