OpenStack-Placement、nova元件部署

一、建立資料庫執行個體和資料庫使用者

[[email protected] ~]# mysql -uroot -p
MariaDB [(none)]> CREATE DATABASE placement;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY 'PLACEMENT_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY 'PLACEMENT_DBPASS';
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> exit；

二、建立Placement服務使用者和API的endpoint

[[email protected] ~]# openstack user create --domain default --password PLACEMENT_PASS placement
//給與placement使用者對service項目擁有admin權限
[[email protected] ~]# openstack role add --project service --user placement admin
//建立一個placement服務，服務類型為placement
[[email protected] ~]# openstack service create --name placement --description "Placement API" placement
//注冊API端口到placement的service中；注冊的資訊會寫入到mysql中
[[email protected] ~]# openstack endpoint create --region RegionOne placement public http://ct:8778
[[email protected] ~]# openstack endpoint create --region RegionOne placement internal http://ct:8778
[[email protected]~]# openstack endpoint create --region RegionOne placement admin http://ct:8778

安裝placement服務

[[email protected] ~]# yum -y install openstack-placement-api
//修改placement配置檔案
cp /etc/placement/placement.conf /etc/placement/placement.conf.bak
grep -Ev '^$|#' /etc/placement/placement.conf.bak > /etc/placement/placement.conf
openstack-config --set /etc/placement/placement.conf placement_database connection mysql+pymysql://placement:[email protected]/placement
openstack-config --set /etc/placement/placement.conf api auth_strategy keystone
openstack-config --set /etc/placement/placement.conf keystone_authtoken auth_url  http://ct:5000/v3
openstack-config --set /etc/placement/placement.conf keystone_authtoken memcached_servers ct:11211

openstack-config --set /etc/placement/placement.conf keystone_authtoken username placement
openstack-config --set /etc/placement/placement.conf keystone_authtoken password PLACEMENT_PASS

//檢視配置檔案
[[email protected] placement]# cat placement.conf
[DEFAULT]
[api]
auth_strategy = keystone
[cors]
[keystone_authtoken]
auth_url = http://ct:5000/v3				#指定keystone位址
memcached_servers = ct:11211			#session資訊是緩存放到了memcached中
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = placement
password = PLACEMENT_PASS
[oslo_policy]
[placement]
[placement_database]
connection = mysql+pymysql://placement:[email protected]/placement
[profiler]

//導入資料庫
su -s /bin/sh -c "placement-manage db sync" placement
//修改Apache配置檔案： 00-placemenct-api.conf（安裝完placement服務後會自動建立該檔案-虛拟主機配置）
#虛拟主機配置檔案
[[email protected] conf.d]# cat 00-placement-api.conf 		#安裝完placement會自動建立此檔案

三、計算節點Nova服務配置

建立nova資料庫，并執行授權操作

[[email protected] ~]# mysql -uroot -p
MariaDB [(none)]> CREATE DATABASE nova_api;
MariaDB [(none)]> CREATE DATABASE nova;
MariaDB [(none)]> CREATE DATABASE nova_cell0;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> exit

管理Nova使用者及服務

//建立nova使用者
[[email protected] ~]# openstack user create --domain default --password NOVA_PASS nova
//把nova使用者添加到service項目，擁有admin權限
[[email protected] ~]# openstack role add --project service --user nova admin
//建立nova服務
[[email protected] ~]# openstack service create --name nova --description "OpenStack Compute" compute
//給Nova服務關聯endpoint（端點）
[[email protected] ~]# openstack endpoint create --region RegionOne compute public http://ct:8774/v2.1
[[email protected] ~]# openstack endpoint create --region RegionOne compute internal http://ct:8774/v2.1
[[email protected] ~]# openstack endpoint create --region RegionOne compute admin http://ct:8774/v2.1

//安裝nova元件（nova-api、nova-conductor、nova-novncproxy、nova-scheduler）
[[email protected] ~]# yum -y install openstack-nova-api openstack-nova-conductor openstack-nova-novncproxy openstack-nova-scheduler

//修改nova配置檔案(nova.conf)
cp -a /etc/nova/nova.conf{,.bak}

初始化資料庫

初始化nova_api資料庫
[[email protected] ~]# su -s /bin/sh -c "nova-manage api_db sync" nova
注冊cell0資料庫；nova服務内部把資源劃分到不同的cell中，把計算節點劃分到不同的cell中；openstack内部基于cell把計算節點進行邏輯上的分組
[[email protected] ~]# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
#建立cell1單元格；
[[email protected] ~]# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
#初始化nova資料庫；可以通過 /var/log/nova/nova-manage.log 日志判斷是否初始化成功
[[email protected] ~]# su -s /bin/sh -c "nova-manage db sync" nova
#可使用以下指令驗證cell0和cell1是否注冊成功
su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova #驗證cell0和cell1元件是否注冊成功

啟動Nova服務

[[email protected] ~]# systemctl enable openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
[[email protected] ~]# systemctl start openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

檢查nova服務端口

[[email protected] ~]# netstat -tnlup|egrep '8774|8775'
[[email protected] ~]# curl http://ct:8774

四、計算節點配置Nova服務-c1節點

安裝nova-compute元件
yum -y install openstack-nova-compute
修改配置檔案
#編輯計算節點節點Nova配置檔案（c1和c2、隻有IP不同）
cp -a /etc/nova/nova.conf{,.bak}

開啟服務

systemctl enable libvirtd.service openstack-nova-compute.service
 systemctl start libvirtd.service openstack-nova-compute.service

【計算節點-c2】與c1相同（除了IP位址）

五、controler節點操作

檢視compute節點是否注冊到controller上，通過消息隊列；需要在controller節點執行
[[email protected] ~]# openstack compute service list --service nova-compute
掃描目前openstack中有哪些計算節點可用，發現後會把計算節點建立到cell中，後面就可以在cell中建立虛拟機；相當于openstack内部對計算節點進行分組，把計算節點配置設定到不同的cell中 
[[email protected] ~]# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
預設每次添加個計算節點，在控制端就需要執行一次掃描，這樣會很麻煩，是以可以修改控制端nova的主配置檔案
[[email protected] ~]# vim /etc/nova/nova.conf
[scheduler]
discover_hosts_in_cells_interval = 300			#每300秒掃描一次

[[email protected] ~]# systemctl restart openstack-nova-api.service

驗證

#檢查 nova 的各個服務是否都是正常，以及 compute 服務是否注冊成功
[[email protected] ~]# openstack compute service list


#檢視各個元件的 api 是否正常
[[email protected] ~]# openstack catalog list

#檢視是否能夠拿到鏡像
[[email protected] ~]# openstack image list

#檢視cell的api和placement的api是否正常，隻要其中一個有誤，後期無法建立虛拟機
[[email protected] ~]# nova-status upgrade check
