上一篇文章分享了glance镜像服务的安装配置，本文主要分享openstack的计算服务Nova的安装和配制方法
------------------ 完美的分割线 ---------------------
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
# nova服务在本版本新增加了两个数据库，需要注意
mysql -u root -p123456 ----------------------------------- 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'; flush privileges; show databases; select user,host from mysql.user; exit ----------------------------------
4.2.在keystone上面注册nova服务
# 创建服务证书
1）在keystone上创建nova用户
cd /server/tools source keystone-admin-pass.sh 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
# 完毕
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 192.168.1.81 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 enabled true openstack-config --set /etc/nova/nova.conf vnc server_listen '$my_ip' openstack-config --set /etc/nova/nova.conf vnc server_proxyclient_address '$my_ip' 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 "^#|^$" /etc/nova/nova.conf
# 实例演示：
[root@openstack01 tools]# egrep -v "^#|^$" /etc/nova/nova.conf [DEFAULT] enabled_apis = osapi_compute,metadata my_ip = 192.168.1.81 use_neutron = true firewall_driver = nova.virt.firewall.NoopFirewallDriver transport_url = rabbit://openstack:openstack@controller [api] auth_strategy = keystone [api_database] connection = mysql+pymysql://nova:nova@controller/nova_api [barbican] [cache] [cells] [cinder] [compute] [conductor] [console] [consoleauth] [cors] [database] connection = mysql+pymysql://nova:nova@controller/nova [devices] [ephemeral_storage_encryption] [filter_scheduler] [glance] api_servers = http://controller:9292 [guestfs] [healthcheck] [hyperv] [ironic] [key_manager] [keystone] [keystone_authtoken] auth_url = http://controller:5000/v3 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = nova [libvirt] [matchmaker_redis] [metrics] [mks] [neutron] [notifications] [osapi_v21] [oslo_concurrency] lock_path = /var/lib/nova/tmp [oslo_messaging_amqp] [oslo_messaging_kafka] [oslo_messaging_notifications] [oslo_messaging_rabbit] [oslo_messaging_zmq] [oslo_middleware] [oslo_policy] [pci] [placement] region_name = RegionOne project_domain_name = Default project_name = service auth_type = password user_domain_name = Default auth_url = http://controller:5000/v3 username = placement password = placement [placement_database] connection = mysql+pymysql://placement:placement@controller/placement [powervm] [profiler] [quota] [rdp] [remote_debug] [scheduler] discover_hosts_in_cells_interval = 300 # 服务端的计算节点多久去检查一次新加入的host主机信息，可以自动将安装好的计算节点主机加入集群 [serial_console] [service_user] [spice] [upgrade_levels] [vault] [vendordata_dynamic_auth] [vmware] [vnc] enabled = true server_listen =$my_ip server_proxyclient_address =$my_ip [workarounds] [wsgi] [xenserver] [xvp] [zvm]
# 以上是生效的配置
3）修改nova的虚拟主机配置文件
# 由于有个包的bug需要配置修改文件，需要修改nova虚拟主机配置文件，增加内容，完整的文件内容如下：
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>

# 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）
# nova_api有32张表，placement有32张表，nova_cell0有110张表，nova也有110张表
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 -h192.168.1.81 -unova -pnova -e "use nova_api;show tables;" mysql -h192.168.1.81 -uplacement -pplacement -e "use placement;show tables;"

# 通过对比可知，nova_api和placement都有32张表，区别在于nova_api数据库的cell_mappings表多两条数据，存放的是nova和rabbitmq等的配置信息
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
