📑1. 作为operator1，使用rhel7镜像在production项目中创建一个名为production-volume1的10 GB可引导卷。

[student@workstation ~]$ source operator1-production-rc 
[student@workstation ~(operator1-production)]$ openstack volume create --image rhel7 --size 10 production-volume1
.........

[student@workstation ~(operator1-production)]$ openstack volume list -c Name -c Status
+--------------------+-------------+
| Name               | Status      |
+--------------------+-------------+
| production-volume1 | downloading |
+--------------------+-------------+

[student@workstation ~(operator1-production)]$ openstack volume list -c Name -c Status
+--------------------+-----------+
| Name               | Status    |
+--------------------+-----------+
| production-volume1 | available |
+--------------------+-----------+

📑2. 作为operator1，在production项目中创建一个名为production-volume2的空1GB卷。

[student@workstation ~(operator1-production)]$ openstack volume create --size 1 production-volume2
.........

[student@workstation ~(operator1-production)]$ openstack volume list -c Name -c Status
+--------------------+-----------+
| Name               | Status    |
+--------------------+-----------+
| production-volume2 | available |
| production-volume1 | available |
+--------------------+-----------+

📑3. 验证新卷是否作为对象存在于卷Ceph池中。

[student@workstation ~(operator1-production)]$ openstack volume list -c Name -c Status -c ID
+--------------------------------------+--------------------+-----------+
| ID                                   | Name               | Status    |

| f00c04a9-d211-4fe8-8cba-50d8cf7021fe | production-volume1 | available |
+--------------------------------------+--------------------+-----------+
[root@controller0 ~]# rados -p volumes ls | grep f00c04a9-d211-4fe8-8cba-50d8cf7021fe
rbd_id.volume-f00c04a9-d211-4fe8-8cba-50d8cf7021fe
[root@controller0 ~]# rados -p volumes ls | grep 1d377d0d-0241-409f-94b7-b09f47fbf2d4
rbd_id.volume-1d377d0d-0241-409f-94b7-b09f47fbf2d4

📑4. 作为operator1，使用production-volume1可引导卷在production项目中使用以下参数启动一个实例。

在这里插入图片描述

[student@workstation ~(operator1-production)]$ openstack server create --flavor default --volume production-volume1 --key-name operator1-keypair --nic net-id=production-network1  --wait production-server1
........

[student@workstation ~(operator1-production)]$ openstack server add volume production-server1 production-volume2
[student@workstation ~(operator1-production)]$ openstack volume list
+--------------------------------------+--------------------+--------+------+---------------------------------------------+
| ID                                   | Name               | Status | Size | Attached to                                 |
+--------------------------------------+--------------------+--------+------+---------------------------------------------+

| f00c04a9-d211-4fe8-8cba-50d8cf7021fe | production-volume1 | in-use |   10 | Attached to production-server1 on /dev/vda  |
+--------------------------------------+--------------------+--------+------+---------------------------------------------+

📑5. 访问production-server1实例，并验证空的production-volume2卷已成功连接到production-server1实例。

[student@workstation ~(operator1-production)]$ openstack floating ip list
+--------------------------------------+---------------------+------------------+------+--------------------------------------+----------------------------------+
| ID                                   | Floating IP Address | Fixed IP Address | Port | Floating Network                     | Project                          |
+--------------------------------------+---------------------+------------------+------+--------------------------------------+----------------------------------+

+--------------------------------------+---------------------+------------------+------+--------------------------------------+----------------------------------+
[student@workstation ~(operator1-production)]$ openstack server add floating ip production-server1 172.25.250.151
[student@workstation ~(operator1-production)]$ ssh 172.25.250.151
Warning: Permanently added '172.25.250.151' (ECDSA) to the list of known hosts.

📑6. 卷挂载测试

在production-volume2中创建一个1 GB的分区，在production-server1实例的分区表中作为设备vdb。使用xfs文件系统类型格式化分区，并将其临时挂载到/mnt上。创建文件/mnt/hello.txt，其中hello作为文本消息。文件/mnt/hello.txt被调整到production-volume2中，/mnt充当卷的挂载点。另外，创建文件/hello2。以hello2作为文本消息的txt。文件/hello2.txt被调整到production-volume1中，因为在production-server1实例中使用该卷作为根文件系统。

📑7.删除现有的production-server1实例，并使用以下参数创建一个新的实例，将production-volume1作为可引导的卷。

在这里插入图片描述

[student@workstation ~(operator1-production)]$ openstack server delete production-server1
[student@workstation ~(operator1-production)]$ openstack server create --flavor default --volume production-volume1 --key-name operator1-keypair --nic net-id=production-network1  --wait production-server1
.........

[student@workstation ~(operator1-production)]$ openstack server add volume production-server1 production-volume2
[student@workstation ~(operator1-production)]$ openstack volume list
+--------------------------------------+--------------------+--------+------+---------------------------------------------+
| ID                                   | Name               | Status | Size | Attached to                                 |
+--------------------------------------+--------------------+--------+------+---------------------------------------------+

| f00c04a9-d211-4fe8-8cba-50d8cf7021fe | production-volume1 | in-use |   10 | Attached to production-server1 on /dev/vda  |
+--------------------------------------+--------------------+--------+------+---------------------------------------------+

📑8. 确认您先前创建的文本文件是否持久保存，以及production-server1实例中的所有内容。

[student@workstation ~(operator1-production)]$ openstack server add floating ip production-server1 172.25.250.151
[student@workstation ~(operator1-production)]$ ssh 172.25.250.151
Last login: Mon Oct 26 02:34:42 2020 from workstation.lab.example.com
[cloud-user@production-server1 ~]$ lsblk

[cloud-user@production-server1 ~]$ sudo mount /dev/vdb1 /mnt/
[cloud-user@production-server1 ~]$ cat /mnt/hello.txt 
hello
[cloud-user@production-server1 ~]$ cat /hello2.txt 
hello2

📑9. 作为operator1，在production项目中创建1 GB共享文件系统。

将共享文件系统的名称设置为production-share1，类型设置为cephfstype。在创建production-share1时使用cephfs协议。对于管理操作(比如管理共享文件系统的类型)，可以使用architect1租户用户。

📑10. 将一个额外的NIC从提供程序存储网络附加到production-server1实例，以便从production-server1实例到达production-share1共享文件系统的网络配置。使用DHCP作为附加网卡的配置方法。

💡总结

  • 基于块的、基于对象的和基于文件的存储选项具有各自的适用性和用例。这些存储选项并不相互替代或替代。基于块的存储选项提供了更高的可靠性，基于对象的存储提供了更好的可伸缩性，基于文件的存储为租户用户扩展了简单性。

  • RedHat OpenStack平台同时支持redhat Ceph存储和NFS作为存储后端。

  • Red Hat Ceph存储体系结构基于监视器(MON)守护进程和对象存储设备(OSD)守护进程。

  • 红帽Ceph存储功能包括无缝可伸缩性和没有单点故障。

  • Red Hat Ceph存储使用CephX身份验证机制来识别和授权用户。

  • 红帽OpenStack平台的块存储和镜像服务使用RBDs来访问Ceph，并且需要用户和池来访问集群。

  • Red Hat OpenStack平台对象存储服务(Swift)为租户用户提供可伸缩的对象存储。

  • OpenStack对象存储体系结构包括一个前端服务、代理服务器和三个后端服务：帐户服务器、对象服务器和容器服务器。

  • 用户可以在对象存储中创建容器，并将对象上传到这些容器中。

  • OpenStack共享文件系统服务管理为基于文件的存储需求提供服务的共享。来自实例的用户作为远程文件系统访问共享。共享可以托管在各种后端存储提供程序上，包括但不限于红帽Ceph存储和红帽Gluster存储。

  • 与持久存储持久存储数据不同，临时存储中的数据在实例终止后不会持久存储。持久存储主要存储可重用的数据。

RHCA认证需要经历5门的学习与考试，还是需要花不少时间去学习与备考的，好好加油，可以噶🤪。
