controller
一、创建nova数据库,并设置权限及远程登录
mysql -u root -p
CREATE DATABASE nova_api;
CREATE DATABASE nova;
CREATE DATABASE nova_cell0;
GRANT ALL PRIVILEGES ON nova_api.* TO ‘nova‘@‘localhost‘ \ IDENTIFIED BY ‘NOVA_DBPASS‘;
GRANT ALL PRIVILEGES ON nova_api.* TO ‘nova‘@‘%‘ \ IDENTIFIED BY ‘NOVA_DBPASS‘;
GRANT ALL PRIVILEGES ON nova.* TO ‘nova‘@‘localhost‘ \ IDENTIFIED BY ‘NOVA_DBPASS‘;
GRANT ALL PRIVILEGES ON nova.* TO ‘nova‘@‘%‘ \ IDENTIFIED BY ‘NOVA_DBPASS‘;
GRANT ALL PRIVILEGES ON nova_cell0.* TO ‘nova‘@‘localhost‘ \ IDENTIFIED BY ‘NOVA_DBPASS‘;
GRANT ALL PRIVILEGES ON nova_cell0.* TO ‘nova‘@‘%‘ \ IDENTIFIED BY ‘NOVA_DBPASS‘;
二、创建nova用户
①创建nova用户
source openrc
openstack user create --domain default --password=nova nova
②将default项目中的nova用户设置成admin角色
openstack role add --project service --user nova admin
③创建nova服务
openstack service create --name nova \ --description "OpenStack Compute" compute
④创建nova服务端点
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
三、创建placement用户(起到统计资源使用的功能)
①创建placement用户
openstack user create --domain default --password=placement placement
②将service项目中的placement用户设置成admin角色
openstack role add --project service --user placement admin
③创建服务
openstack service create --name placement --description "Placement API" placement
④创建服务端点
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
四、安装nova
①安装nova服务包
yum install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler openstack-nova-placement-api
②修改nova配置文件
cp /etc/nova/nova.conf
/etc/nova/nova.conf
.bak
[DEFAULT] my_ip=192.168.42.120 #控制节点ip use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver #防火墙驱动 enabled_apis=osapi_compute,metadata transport_url = rabbit://openstack:[email protected] #rabbitmq的连接方式 [api] auth_strategy = keystone [api_database] connection = mysql+pymysql://nova:[email protected]/nova_api [barbican] [cache] [cells] [cinder] #os_region_name = RegionOne [cloudpipe] [conductor] [console] [consoleauth] [cors] [cors.subdomain] [crypto] [database] connection = mysql+pymysql://nova:[email protected]/nova [ephemeral_storage_encryption] [filter_scheduler] [glance] api_servers = http://controller:9292 [guestfs] [healthcheck] [hyperv] [image_file_url] [ironic] [key_manager] [keystone_authtoken] auth_uri = http://controller:5000 auth_url = http://controller:35357 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = nova [libvirt] #virt_type=qemu [matchmaker_redis] [metrics] [mks] [neutron] #url = http://controller:9696 #auth_url = http://controller:35357 #auth_type = password #project_domain_name = default #user_domain_name = default #region_name = RegionOne #project_name = service #username = neutron #password = neutron #service_metadata_proxy = true #metadata_proxy_shared_secret = METADATA_SECRET [notifications] [osapi_v21] [oslo_concurrency] lock_path=/var/lib/nova/tmp #临时文件保存位置 [oslo_messaging_amqp] [oslo_messaging_kafka] [oslo_messaging_notifications] [oslo_messaging_rabbit] [oslo_messaging_zmq] [oslo_middleware] [oslo_policy] [pci] [placement] os_region_name = RegionOne auth_type = password auth_url = http://controller:35357/v3 #认证的地址 project_name = service project_domain_name = Default username = placement password = placement user_domain_name = Default [quota] [rdp] [remote_debug] [scheduler] [serial_console] [service_user] [spice] [ssl] [trusted_computing] [upgrade_levels] [vendordata_dynamic_auth] [vmware] [vnc] #可以连接虚拟机 enabled=true vncserver_listen=$my_ip #监听ip地址 vncserver_proxyclient_address=$my_ip #vnc代理服务监听地址 #novncproxy_base_url = http://172.16.254.63:6080/vnc_auto.html [workarounds] [wsgi] [xenserver] [xvp]
vim /etc/noa/nova.conf
③创建一个服务追踪的配置文件(补充到文件的末尾)
vim /etc/httpd/conf.d/00-nova-placement-api.conf
<Directory /usr/bin>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>
Order allow,deny
Allow from all
</IfVersion>
</Directory>
④重启httpd服务
systemctl restart httpd
⑤同步api、cell0数据库
su -s /bin/sh -c "nova-manage api_db sync" nova
su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
⑥创建cell证书的id
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
⑦同步nova数据库
su -s /bin/sh -c "nova-manage db sync" nova
⑧列示cell证书列表
nova-manage cell_v2 list_cells
⑨重启并设置开机自启
systemctl enable openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
systemctl start openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
compute
openstack的库都建立在控制节点上,其他节点不需要建库
①安装nova包(先解决依赖)yum安装
qemu-img-ev-2.9.0-16.el7_4.8.1.x86_64.rpm qemu-kvm-ev-2.9.0-16.el7_4.8.1.x86_64.rpm qemu-kvm-common-ev-2.9.0-16.el7_4.8.1.x86_64.rpm
yum install openstack-nova-compute
②编辑nova配置文件
cp /etc/nova/nova.conf
/etc/nova/nova.conf
.bak
[DEFAULT] my_ip=192.168.42.121 #管理网卡的ip地址 use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver enabled_apis=osapi_compute,metadata transport_url = rabbit://openstack:[email protected] [api] #auth_strategy = keystone [api_database] #connection = mysql+pymysql://nova:[email protected]/nova_api [barbican] [cache] [cells] [cinder] #os_region_name = RegionOne [cloudpipe] [conductor] [console] [consoleauth] [cors] [cors.subdomain] [crypto] [database] #connection = mysql+pymysql://nova:[email protected]/nova [ephemeral_storage_encryption] [filter_scheduler] [glance] api_servers = http://controller:9292 [guestfs] [healthcheck] [hyperv] [image_file_url] [ironic] [key_manager] [keystone_authtoken] auth_uri = http://controller:5000 auth_url = http://controller:35357 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = nova [libvirt] virt_type=qemu #调用后台虚拟化 [matchmaker_redis] [metrics] [mks] [neutron] #url = http://controller:9696 #auth_url = http://controller:35357 #auth_type = password #project_domain_name = default #user_domain_name = default #region_name = RegionOne #project_name = service #username = neutron #password = neutron #service_metadata_proxy = true #metadata_proxy_shared_secret = METADATA_SECRET [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] os_region_name = RegionOne auth_type = password auth_url = http://controller:35357/v3 project_name = service project_domain_name = Default username = placement password = placement user_domain_name = Default [quota] [rdp] [remote_debug] [scheduler] [serial_console] [service_user] [spice] [ssl] [trusted_computing] [upgrade_levels] [vendordata_dynamic_auth] [vmware] [vnc] enabled=true vncserver_listen=0.0.0.0 vncserver_proxyclient_address=$my_ip novncproxy_base_url = http://controller:6080/vnc_auto.html #控制节点地址 [workarounds] [wsgi] [xenserver] [xvp]
vim /etc/nova/nova.conf
③过滤计算节点是否开启虚拟化
egrep -c ‘(vmx|svm)‘ /proc/cpuinfo
④重启并设置开启自启
systemctl enable libvirtd.service openstack-nova-compute.service
· systemctl start libvirtd.service openstack-nova-compute.service #启不来查看日志,具体错误具体解决
⑤列示openstack管理虚拟化类型
openstack hypervisor list
⑥数据库同步计算接节点
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
⑦在控制节点查看计算服务的工作状态
openstack compute service list(enable表示开启,up运行)
openstack catalog list (查看服务列表)
openstack image list (查看镜像列表)
nova-status upgrade check (nova状态服务检测)
显示都成功即可
