OpenStack雲平臺部署

前言：本次部署採用系統的是Centos 8-Stream版，儲存庫為OpenStack-Victoria版，除基礎設定，五大服務中的時間同步服務，七大元件中的nova服務，neutron服務，cinder服務需要在雙節點設定外，其他服務設定均在控制節點，neutron設定從公有網路和私有網路中選擇一種即可，大多數情況還是選公有網路的設定，此次部署所有密碼均為111111，可按自身需要自行設定

安裝環境：

採用虛擬化軟體：VMware Workstation 16 Pro
作業系統：Centos 8-Stream
控制節點設定：記憶體4G，CPU4核，磁碟100G，啟用虛擬化引擎
計算節點設定：記憶體4G，CPU4核，磁碟100G，啟用虛擬化引擎

基礎設定(雙節點)

Yum源倉庫設定

阿里雲映象倉庫地址：https://mirrors.aliyun.com，有需要可自行設定，但是這裡用不到

（1）設定Centos 8的源只需改yum倉庫.repo檔案引數即可如下

#更改CentOS-Stream-AppStream.repo檔案，將baseurl引數中的地址改為https://mirrors.aliyun.com

[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# vi CentOS-Stream-AppStream.repo 
[appstream]
name=CentOS Stream $releasever - AppStream
#mirrorlist=http://mirrorlist.centos.org/?   release=$stream&arch=$basearch&repo=AppStream&infra=$infra
baseurl=https://mirrors.aliyun.com/$contentdir/$stream/AppStream/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial


#更改CentOS-Stream-BaseOS.repo 檔案，將baseurl引數中的地址改為https://mirrors.aliyun.com

[root@localhost yum.repos.d]# vi CentOS-Stream-BaseOS.repo 
[baseos]
name=CentOS Stream $releasever - BaseOS
#mirrorlist=http://mirrorlist.centos.org/?release=$stream&arch=$basearch&repo=BaseOS&infra=$infra
baseurl=https://mirrors.aliyun.com/$contentdir/$stream/BaseOS/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial


#更改CentOS-Stream-Extras.repo 檔案，將baseurl引數中的地址改為https://mirrors.aliyun.com

[root@localhost yum.repos.d]# vi CentOS-Stream-Extras.repo 
[extras]
name=CentOS Stream $releasever - Extras
#mirrorlist=http://mirrorlist.centos.org/?release=$stream&arch=$basearch&repo=extras&infra=$infra
baseurl=https://mirrors.aliyun.com/$contentdir/$stream/extras/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

（2）設定openstack源

#在yum倉庫資料夾下面建立openstack-victoria.repo檔案

(10) 檢視nova服務是否啟動

[root@controller ~]# nova service-list

#一般只會顯示兩個服務：nova-scheduler和nova-conductor，這是因為上面這條命令是由nova-api接收，而它控制著nova-scheduler和nova-conductor服務，如果nova-api未開啟，那這兩個服務也會down掉，nova-novncproxy服務則是通過檢視埠號的形式，範例如下：
[root@controller ~]# netstat -lntup | grep 6080
tcp        0      0 0.0.0.0:6080            0.0.0.0:*               LISTEN      1456/python3   
[root@controller ~]# ps -ef | grep 1456

#編輯
[root@compute ~]# vim /etc/nova/nova.conf
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:111111@controller
my_ip = 10.10.10.20				#本機IP，如果將來換IP，這地方一定要改

MariaDB [cinder]> show tables;
MariaDB [cinder]> quit

(5) 建立cinder使用者和服務，關聯admin角色

#建立cinder使用者
[root@controller ~]# openstack user create --domain default --password 111111 placement

#關聯admin角色
[root@controller ~]# openstack role add --project service --user cinder admin

#建立cinderv2,cinderv3服務
[root@controller ~]# openstack service create --name cinderv2 \>   --description "OpenStack Block Storage" volumev2
[root@controller ~]# openstack service create --name cinderv3 \>   --description "OpenStack Block Storage" volumev3

(6) 註冊API介面

cinderv2的伺服器端點

#public
[root@controller ~]# openstack endpoint create --region RegionOne \
>   volumev2 public http://controller:8776/v2/%\(project_id\)s

#internal
[root@controller ~]# openstack endpoint create --region RegionOne \
>   volumev2 internal http://controller:8776/v2/%\(project_id\)s

#admin
[root@controller ~]# openstack endpoint create --region RegionOne \
>   volumev2 admin http://controller:8776/v2/%\(project_id\)s

cinderv3的伺服器端點

#public
[root@controller ~]# openstack endpoint create --region RegionOne \
>   volumev3 public http://controller:8776/v3/%\(project_id\)s

#internal
[root@controller ~]# openstack endpoint create --region RegionOne \
>   volumev3 internal http://controller:8776/v3/%\(project_id\)s

#admin
[root@controller ~]# openstack endpoint create --region RegionOne \
>   volumev3 admin http://controller:8776/v3/%\(project_id\)s

(7) 檢視伺服器端點

[root@controller ~]# openstack endpoint list

(8) 設定計算服務使用塊儲存

#編輯nova組態檔
[root@controller cinder]# vi /etc/nova/nova.conf
[cinder]
os_region_name = RegionOne

#重啟nova
[root@controller ~]# systemctl restart openstack-nova-api.service

(9) 啟動cinder服務並設定開機自啟

[root@controller ~]# systemctl enable --now openstack-cinder-api.service openstack-cinder-scheduler.service

計算節點（關閉虛擬機器器新增一塊50G硬碟）

(1) 檢視磁碟

[root@compute ~]# fdisk --list

(2) 安裝 LVM 包

[root@compute ~]# dnf -y install lvm2 device-mapper-persistent-data

(3) 建立 LVM 物理卷/dev/sdb

[root@compute ~]# pvcreate /dev/sdb

(4) 建立 LVM 卷組cinder-volumes

[root@compute ~]# vgcreate cinder-volumes /dev/sdb

(5) 修改LVM設定

#複製一份去掉註釋
[root@compute ~]# cp /etc/lvm/lvm.conf /etc/lvm/lvm.conf.bak
[root@compute ~]# grep -Ev '^$|#' /etc/lvm/lvm.conf.bak > /etc/lvm/lvm.conf

#編輯
[root@compute ~]# vi /etc/lvm/lvm.conf
devices {
        filter = [ "a/sda/",a/sdb/", "r/.*/"]
}

(6) 安裝cinder相關軟體包

[root@compute ~]# dnf install -y openstack-cinder targetcli python3-keystone

(7) 編輯cinder組態檔

#複製一份去掉註釋
[root@compute ~]# cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.bak
[root@compute ~]# grep -Ev '^$|#' /etc/cinder/cinder.conf.bak > /etc/cinder/cinder.conf

#編輯
[root@compute ~]# vim /etc/cinder/cinder.conf
[DEFAULT]
transport_url = rabbit://openstack:111111@controller
auth_strategy = keystone
my_ip = 10.10.10.20
enabled_backends = lvm
glance_api_servers = http://controller:9292

[database]
connection = mysql+pymysql://cinder:111111@controller/cinder

[keystone_authtoken]
www_authenticate_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 = cinder
password = 111111

[lvm]					#沒有就新增
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes				#要與建立的卷組名對應
target_protocol = iscsi
target_helper = lioadm

[oslo_concurrency]
lock_path = /var/lib/cinder/tmp

(8) 啟動cinder服務並設定開機自啟

[root@compute ~]# systemctl enable --now openstack-cinder-volume.service target.service

(9) 返回控制節點，檢視服務列表

[root@controller ~]# openstack volume service list
#顯示這樣就行
