nova相关端口：
api:8774 metadata:8775 novncproxy:6080
4.1.在控制节点安装nova计算服务
1）创建nova相关数据库
# 登录数据库 mysql -u root -p # 创建用户并授权 CREATE DATABASE nova_api; CREATE DATABASE nova; CREATE DATABASE nova_cell0; CREATE DATABASE placement; GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'nova'; GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'nova'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'nova'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova'; GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'nova'; GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'nova'; GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY 'placement'; GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY 'placement'; # 刷新权限 flush privileges;
4.2.在keystone上面注册nova服务
1）在keystone上创建nova用户
openstack user create --domain default --password=nova nova openstack user list
2）在keystone上将nova用户配置为admin角色并添加进service项目
# 以下命令无输出
openstack role add --project service --user nova admin
3）创建nova计算服务的实体
openstack service create --name nova --description "OpenStack Compute" compute openstack service list
4）创建计算服务的API端点（endpoint）
# 计算服务compute
openstack endpoint create --region RegionOne compute public http://controller:8774/v2.1 openstack endpoint create --region RegionOne compute internal http://controller:8774/v2.1 openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1 openstack endpoint list
5）这个版本的nova增加了placement项目
# 同样，创建并注册该项目的服务证书
openstack user create --domain default --password=placement placement openstack role add --project service --user placement admin openstack service create --name placement --description "Placement API" placement
# 创建placement项目的endpoint（API端口）
openstack endpoint create --region RegionOne placement public http://controller:8778 openstack endpoint create --region RegionOne placement internal http://controller:8778 openstack endpoint create --region RegionOne placement admin http://controller:8778 openstack endpoint list
4.3.在控制节点安装nova相关服务
1）安装nova相关软件包
yum install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler openstack-nova-placement-api -y
2）快速修改nova配置
openstack-config --set /etc/nova/nova.conf DEFAULT enabled_apis osapi_compute,metadata openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 192.168.182.143 openstack-config --set /etc/nova/nova.conf DEFAULT use_neutron true openstack-config --set /etc/nova/nova.conf DEFAULT firewall_driver nova.virt.firewall.NoopFirewallDriver openstack-config --set /etc/nova/nova.conf DEFAULT transport_url rabbit://openstack:openstack@controller openstack-config --set /etc/nova/nova.conf api_database connection mysql+pymysql://nova:nova@controller/nova_api openstack-config --set /etc/nova/nova.conf database connection mysql+pymysql://nova:nova@controller/nova openstack-config --set /etc/nova/nova.conf placement_database connection mysql+pymysql://placement:placement@controller/placement openstack-config --set /etc/nova/nova.conf api auth_strategy keystone openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_url http://controller:5000/v3 openstack-config --set /etc/nova/nova.conf keystone_authtoken memcached_servers controller:11211 openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_type password openstack-config --set /etc/nova/nova.conf keystone_authtoken project_domain_name default openstack-config --set /etc/nova/nova.conf keystone_authtoken user_domain_name default openstack-config --set /etc/nova/nova.conf keystone_authtoken project_name service openstack-config --set /etc/nova/nova.conf keystone_authtoken username nova openstack-config --set /etc/nova/nova.conf keystone_authtoken password nova openstack-config --set /etc/nova/nova.conf vnc vncserver_listen 192.168.182.143 openstack-config --set /etc/nova/nova.conf vnc vncserver_proxyclient_address 192.168.182.143 openstack-config --set /etc/nova/nova.conf vnc vnc_enabled True openstack-config --set /etc/nova/nova.conf vnc novncproxy_host 0.0.0.0 openstack-config --set /etc/nova/nova.conf vnc novncproxy_port 6080 openstack-config --set /etc/nova/nova.conf vnc novncproxy_base_url http://192.168.182.143:6080/vnc_auto.html openstack-config --set /etc/nova/nova.conf glance api_servers http://controller:9292 openstack-config --set /etc/nova/nova.conf oslo_concurrency lock_path /var/lib/nova/tmp openstack-config --set /etc/nova/nova.conf placement region_name RegionOne openstack-config --set /etc/nova/nova.conf placement project_domain_name Default openstack-config --set /etc/nova/nova.conf placement project_name service openstack-config --set /etc/nova/nova.conf placement auth_type password openstack-config --set /etc/nova/nova.conf placement user_domain_name Default openstack-config --set /etc/nova/nova.conf placement auth_url http://controller:5000/v3 openstack-config --set /etc/nova/nova.conf placement username placement openstack-config --set /etc/nova/nova.conf placement password placement openstack-config --set /etc/nova/nova.conf scheduler discover_hosts_in_cells_interval 300
# 默认情况下，计算服务使用内置的防火墙服务。由于网络服务包含了防火墙服务，必须使用``nova.virt.firewall.NoopFirewallDriver``防火墙服务来禁用掉计算服务内置的防火墙服务
# 检查生效的nova配置
egrep -v "^#|^$" /etc/nova/nova.conf
3）修改nova的虚拟主机配置文件（vim /etc/httpd/conf.d/00-nova-placement-api.conf）
Listen 8778 <VirtualHost *:8778> WSGIProcessGroup nova-placement-api WSGIApplicationGroup %{GLOBAL} WSGIPassAuthorization On WSGIDaemonProcess nova-placement-api processes=3 threads=1 user=nova group=nova WSGIScriptAlias / /usr/bin/nova-placement-api <IfVersion >= 2.4> ErrorLogFormat "%M" </IfVersion> ErrorLog /var/log/nova/nova-placement-api.log #SSLEngine On #SSLCertificateFile ... #SSLCertificateKeyFile ... </VirtualHost> Alias /nova-placement-api /usr/bin/nova-placement-api <Location /nova-placement-api> SetHandler wsgi-script Options +ExecCGI WSGIProcessGroup nova-placement-api WSGIApplicationGroup %{GLOBAL} WSGIPassAuthorization On </Location> <Directory /usr/bin> <IfVersion >= 2.4> Require all granted </IfVersion> <IfVersion < 2.4> Order allow,deny Allow from all </IfVersion> </Directory>
# 修改完毕重启httpd服务
systemctl restart httpd
systemctl status httpd
# 至此，nova计算服务的软件包安装完成
4.4.同步nova数据（注意同步顺序）
1）初始化nova-api和placement数据库
su -s /bin/sh -c "nova-manage api_db sync" nova
# 验证数据库
mysql -h192.168.182.143 -unova -pnova -e "use nova_api;show tables;"
mysql -h192.168.182.143 -uplacement -pplacement -e "use placement;show tables;"
2）初始化nova_cell0和nova数据库
# 注册cell0数据库
su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
# 创建cell1单元
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
# 初始化nova数据库
su -s /bin/sh -c "nova-manage db sync" nova
# 检查确认cell0和cell1注册成功
su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova
# 验证数据库
mysql -h192.168.182.143 -unova -pnova -e "use nova_cell0;show tables;"
mysql -h192.168.182.143 -unova -pnova -e "use nova;show tables;"
5）检查确认cell0和cell1注册成功
su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova
# 返回的数据存储在nova_api数据库的cell_mappings表中
4.5.启动nova服务
1）启动nova服务并设置为开机自启动
systemctl start openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service systemctl status openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service systemctl enable openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
systemctl list-unit-files |grep openstack-nova* |grep enabled
~~~至此，在控制节点安装nova计算服务就完成了~~~
