09-OpenStack-queens版-控制節(jié)點(diǎn)上Nova計(jì)算服務(wù)

一鳖孤、概述
使用OpenStack計(jì)算服務(wù)來托管和管理云計(jì)算系統(tǒng)。OpenStack計(jì)算服務(wù)是基礎(chǔ)設(shè)施即服務(wù)(IaaS)系統(tǒng)的主要部分，模塊主要由Python實(shí)現(xiàn)。
OpenStack計(jì)算組件請(qǐng)求OpenStack Identity服務(wù)進(jìn)行認(rèn)證判耕；請(qǐng)求OpenStack Image服務(wù)提供磁盤鏡像；為OpenStack dashboard提供用戶與管理員接口翘骂。磁盤鏡像訪問限制在項(xiàng)目與用戶上壁熄；配額以每個(gè)項(xiàng)目進(jìn)行設(shè)定（例如，每個(gè)項(xiàng)目下可以創(chuàng)建多少實(shí)例）碳竟。OpenStack
組件可以在標(biāo)準(zhǔn)硬件上水平大規(guī)模擴(kuò)展草丧，并且下載磁盤鏡像啟動(dòng)虛擬機(jī)實(shí)例。
　 OpenStack計(jì)算服務(wù)由下列組件所構(gòu)成：
nova-api 服務(wù)：接受并響應(yīng)所有計(jì)算服務(wù)請(qǐng)求莹桅，管理虛擬機(jī)（云主機(jī)）生命周期昌执。
nova-api-metadata 服務(wù)：接受來自虛擬機(jī)發(fā)送的元數(shù)據(jù)請(qǐng)求。
nova-compute服務(wù)（多個(gè)）：真正管理虛擬機(jī)（nova-compute調(diào)用libvirt）统翩。
nova-scheduler服務(wù)：nova調(diào)度器（挑選出最合適的nova-compute來創(chuàng)建虛擬機(jī)）仙蚜。
nova-conductor模塊：幫助nova-compute代理修改數(shù)據(jù)庫(kù)中虛擬機(jī)的狀態(tài)。
nova-cert模塊：服務(wù)器守護(hù)進(jìn)程向Nova Cert服務(wù)提供X509證書厂汗。用來為euca-bundle-image生成證書委粉。僅僅是在EC2 API的請(qǐng)求中使用
nova-network worker 守護(hù)進(jìn)程：與nova-compute服務(wù)類似，從隊(duì)列中接受網(wǎng)絡(luò)任務(wù)娶桦，并且操作網(wǎng)絡(luò)贾节。執(zhí)行任務(wù)例如創(chuàng)建橋接的接口或者改變IPtables的規(guī)則。
nova-consoleauth 守護(hù)進(jìn)程和nova-novncproxy 守護(hù)進(jìn)程：web版的vnc來直接操作云主機(jī)衷畦。
nova-spicehtml5proxy 守護(hù)進(jìn)程：提供一個(gè)代理栗涂，用于訪問正在運(yùn)行的實(shí)例，通過 SPICE 協(xié)議祈争，支持基于瀏覽器的 HTML5 客戶端斤程。
nova-xvpvncproxy 守護(hù)進(jìn)程：提供一個(gè)代理，用于訪問正在運(yùn)行的實(shí)例菩混，通過VNC協(xié)議忿墅，支持OpenStack特定的Java客戶端。
nova-cert 守護(hù)進(jìn)程：X509 證書沮峡。
nova客戶端：用于用戶作為租戶管理員或最終用戶來提交命令疚脐。
隊(duì)列：一個(gè)在守護(hù)進(jìn)程間傳遞消息的中央集線器。

1邢疙、安裝和配置Nova計(jì)算服務(wù)之前棍弄，必須創(chuàng)建數(shù)據(jù)庫(kù)望薄，服務(wù)憑證和API端點(diǎn)。
1）確認(rèn)安裝mariadb呼畸，以root用戶身份登陸痕支，使數(shù)據(jù)庫(kù) 訪問客戶端連接到數(shù)據(jù)庫(kù)服務(wù)器
[root@controller ~]# mysql -u root -p #以root用戶身份登陸
Enter password: （密碼whj1218）
2）創(chuàng)建數(shù)據(jù)庫(kù)nova、nova_api蛮原、nova_cell0采转、placement
MariaDB [(none)]> CREATE DATABASE nova; #創(chuàng)建數(shù)據(jù)庫(kù)nova
MariaDB [(none)]> CREATE DATABASE nova_api; #創(chuàng)建數(shù)據(jù)庫(kù)nova_api
MariaDB [(none)]> CREATE DATABASE nova_cell0; #創(chuàng)建數(shù)據(jù)庫(kù)nova_cell0
MariaDB [(none)]> CREATE DATABASE placement; #創(chuàng)建數(shù)據(jù)庫(kù)placement
MariaDB [(none)]> show databases;#查數(shù)據(jù)表
+--------------------+
| Database |
+--------------------+
| glance |
| information_schema |
| keystone |
| mysql |
| nova |
| nova_api |
| nova_cell0 |
| performance_schema |
| placement |
+--------------------+
3）對(duì)上面創(chuàng)建的數(shù)據(jù)庫(kù)授予合適賬戶訪問權(quán)限
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'whj1218' ;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'whj1218';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'whj1218';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'whj1218';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'whj1218';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'whj1218';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_placement.* TO 'nova'@'localhost' IDENTIFIED BY 'whj1218';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_placement.* TO 'nova'@'%' IDENTIFIED BY 'whj1218';
MariaDB [(none)]> select user,host from mysql.user;
+----------+-----------+
| user | host |
+----------+-----------+
| glance | % |
| keystone | % |
| nova | % |
| root | 127.0.0.1 |
| root | ::1 |
| glance | localhost |
| keystone | localhost |
| nova | localhost |
| root | localhost |
+----------+-----------+
MariaDB [(none)]> quit #退出數(shù)據(jù)庫(kù)

2.在keystone上面注冊(cè)nova服務(wù)
1）在keystone上創(chuàng)建nova用戶
[root@controller ~]# source keystone-admin-pass.sh #加載admin憑據(jù)的環(huán)境變量

[root@controller ~]# openstack user create --domain default --password=whj1218 #nova 創(chuàng)建用戶nova

[root@controller ~]# openstack user create --domain default --password-prompt nova
User Password: ，密碼whj1218
Repeat User Password:
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | d41274fd47e044d4baef61aeef98d0c8 |
| name | nova |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+
[root@controller ~]# openstack user list #列出用戶
+----------------------------------+---------+
| ID | Name |
+----------------------------------+---------+
| 4640a445474e44abba73328aa81a805b | admin |
| 9c1f982fc354433dbea4d060681619bf | myuser |
| 0356c4d61dcf4afb9d8df45c1dea3ffc | my_user |
| b2f7c49185004822957e5e40227b833a | glance |
| d41274fd47e044d4baef61aeef98d0c8 | nova |
+----------------------------------+---------+
2）在keystone上將nova用戶配置為admin角色并添加進(jìn)service項(xiàng)目
[root@controller ~]# openstack role add --project service --user nova admin
3）創(chuàng)建nova計(jì)算服務(wù)的實(shí)體
[root@controller ~]# openstack service create --name nova --description "OpenStack Compute" compute
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Compute |
| enabled | True |
| id | 3a4e43c903d14e2f9f8839d55b62e360 |
| name | nova |
| type | compute |
+-------------+----------------------------------+
[root@controller ~]# openstack service list #列出服務(wù)
+----------------------------------+----------+----------+
| ID | Name | Type |
+----------------------------------+----------+----------+
| 04289507c30f41faa7ba4e5f730db3d0 | glance | image |
| 3a4e43c903d14e2f9f8839d55b62e360 | nova | compute |
| 5bf0447c80e44bc5a68d8ccc554d81e8 | keystone | identity |
+----------------------------------+----------+----------+
4）創(chuàng)建計(jì)算服務(wù)的API端點(diǎn)（endpoint）
創(chuàng)建endpoint
OpenStack使用三個(gè)API端點(diǎn)變種代表每種服務(wù)：admin瞬痘，internal和public。默認(rèn)情況下板熊，管理API端點(diǎn)允許修改用戶和租戶而公共和內(nèi)部APIs不允許這些操作框全。在生產(chǎn)環(huán)境中，處于安全原因干签，變種為了服務(wù)不同類型的用戶可能駐留在單獨(dú)的網(wǎng)絡(luò)上津辩。對(duì)實(shí)例而言，公共API網(wǎng)絡(luò)為了讓顧客管理他們自己的云在互聯(lián)網(wǎng)上是可見的容劳。管理API網(wǎng)絡(luò)在管理云基礎(chǔ)設(shè)施的組織中操作也是有所限制的喘沿。內(nèi)部API網(wǎng)絡(luò)可能會(huì)被限制在包含OpenStack服務(wù)的主機(jī)上。此外竭贩，OpenStack支持可伸縮性的多區(qū)域蚜印。為了簡(jiǎn)單起見，本指南為所有端點(diǎn)變種和默認(rèn)RegionOne區(qū)域都使用管理網(wǎng)絡(luò)留量。

重啟httpd服務(wù)窄赋，查看服務(wù)狀態(tài)

[root@controller ~]# systemctl restart httpd
[root@controller ~]# systemctl status httpd
4.同步nova數(shù)據(jù)（注意同步順序）

nova_api有32張表，placement有32張表楼熄，nova_cell0有110張表忆绰，nova也有110張表

1）初始化nova-api和placement數(shù)據(jù)庫(kù)
[root@controller ~]# su -s /bin/sh -c "nova-manage api_db sync" nova

驗(yàn)證數(shù)據(jù)庫(kù)

[root@controller ~]# mysql -h192.168.136.134 -unova -pwhj1218 -e "use nova_api;show tables;" #有32張數(shù)據(jù)表
[root@controller ~]# mysql -h192.168.136.134 -uplacement -pwhj1218 -e "use placement;show tables;"

通過對(duì)比可知，nova_api和placement都有32張表可岂，區(qū)別在于nova_api數(shù)據(jù)庫(kù)的cell_mappings表多兩條數(shù)據(jù)错敢，存放的是nova和rabbitmq等的配置信息

2）初始化nova_cell0和nova數(shù)據(jù)庫(kù)

注冊(cè)cell0數(shù)據(jù)庫(kù)

[root@controller ~]# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova

創(chuàng)建cell1單元

[root@controller ~]# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova

初始化nova數(shù)據(jù)庫(kù)

[root@controller ~]# su -s /bin/sh -c "nova-manage db sync" nova # 這里遇到兩個(gè)警告信息，不是很嚴(yán)重缕粹，后續(xù)版本會(huì)修復(fù)稚茅，再重新執(zhí)行一下就不會(huì)報(bào)了

檢查確認(rèn)cell0和cell1注冊(cè)成功

返回的數(shù)據(jù)存儲(chǔ)在nova_api數(shù)據(jù)庫(kù)的cell_mappings表中

驗(yàn)證數(shù)據(jù)庫(kù)

[root@controller ~]# mysql -h192.168.136.134 -unova -pwhj1218 -e "use nova_cell0;show tables;"
[root@controller ~]# mysql -h192.168.136.134 -unova -pwhj1218 -e "use nova_api;show tables;"

通過對(duì)比可知，這兩個(gè)數(shù)據(jù)庫(kù)的表目前完全一樣致开，區(qū)別在于nova數(shù)據(jù)庫(kù)的service表中有4條數(shù)據(jù)峰锁，存放的是當(dāng)前版本nova相關(guān)服務(wù)的注冊(cè)信息

[root@controller ~]# systemctl start openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service #啟動(dòng)服務(wù)
[root@controller ~]# systemctl status openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service #查看服務(wù)狀態(tài)
[root@controller ~]# systemctl enable openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service #設(shè)置開機(jī)自啟動(dòng)
[root@controller ~]# systemctl list-unit-files |grep openstack-nova* |grep enabled #檢查是否都開機(jī)啟動(dòng)了
openstack-nova-api.service enabled
openstack-nova-conductor.service enabled
openstack-nova-consoleauth.service enabled
openstack-nova-novncproxy.service enabled
openstack-nova-scheduler.service enabled
至此，在控制節(jié)點(diǎn)安裝nova計(jì)算服務(wù)就完成
