OpenStack m installation Compute (NOVA) service

Configuring the Install Nova Compute service

Installing Controller Nodes

First, create a Nova database

[Email protected] ~]# mysql-u root-p>>create database nova_api;>>create database nova;>>grant all PRI Vileges on nova_api.* to ' nova ' @ ' localhost ' identified by ' nova_dbpass '; >>grant all privileges on nova_api.* to ' n OVA ' @ '% ' identified by ' nova_dbpass '; >>grant-privileges on nova.*-' NOVA ' @ ' localhost ' identified by ' Nova_ Dbpass '; >>grant all privileges on nova.* to ' Nova ' @ ' percent ' identified by ' nova_dbpass ';

Nova_dbpass change to the password you want to set

Ii. Creating service entities and API interfaces

[[email protected] ~] #source  /root/admin-openrc.sh[[email protected] ~]#  Openstack user create --domain default   --password-prompt nova[[email  protected] ~]# openstack role add --project service --user nova  admin[[email protected] ~]# openstack service create --name nova   --description  "Openstack compute"  compute[[email protected] ~]#  openstack endpoint create --region regionone   compute public [[ email protected] ~]# openstack endpoint create --region regionone    compute internal http://controller:8774/v2.1/%\ (tenant_id\) s[[email protected]  ~]# openstack endpoint create --region RegionOne   compute  Admin http://controller:8774/v2.1/%\ (tenant_id\) s 

Third, the installation of Nova services

[email protected] ~]# Yum install Openstack-nova-api openstack-nova-conductor openstack-nova-console Openstack-nova-novncproxy Openstack-nova-scheduler

Editing the Nova service configuration file

[[Email protected] ~]# mv /etc/nova/nova.conf  /etc/nova/nova.conf_bak[default] enabled_apis = osapi_compute,metadatarpc_backend = rabbitauth_strategy =  keystonemy_ip = 10.0.0.11use_neutron = truefirewall_driver =  nova.virt.firewall.noopfirewalldriver[api_database]connection = mysql+pymysql://nova:[email  protected]/nova_api   #改为自己数据库的密码 [database]connection = mysql+pymysql://nova:[email  protected]/nova    #改为自己数据库的密码 [Oslo_messaging_rabbit]rabbit_host = controllerrabbit_ userid = openstackrabbit_password = rabbit_pass    #改为自己rabbitmq的密码 [Keystone _authtoken]auth_uri = http://controller:5000auth_url = http://controller:35357memcached_ Servers = controller:11211auth_type = passwordproject_domain_name = defaultuser_ Domain_name = defaultproject_name = serviceusername = novapassword = nova_pass    #改为自己nova服务的密码 [VNC] vncserver_listen =  $my _ipvncserver_proxyclient_address =  $my _ip[glance]api_servers =  http://controller:9292[oslo_concurrency]lock_path = /var/lib/nova/tmp

Synchronizing databases

[[email protected] ~]# su-s/bin/sh-c "nova-manage api_db Sync" nova[[email protected] ~]# su-s/bin/sh-c "Nova-manage DB Sync "Nova

Start the service and add it to the boot boot

[Email protected] ~]# Systemctl enable Openstack-nova-api.service Openstack-nova-consoleauth.service Openstack-nova-scheduler.service Openstack-nova-conductor.service Openstack-nova-novncproxy.service[[email Protected] ~]# systemctl start Openstack-nova-api.service openstack-nova-consoleauth.service Openstack-nova-scheduler.service Openstack-nova-conductor.service Openstack-nova-novncproxy.service

Installing the COMPUTE node

First, the installation of Nova services

[email protected] ~]# Yum install Openstack-nova-compute

Editing a configuration file

[[email protected] ~] #mv  /etc/nova/nova.conf  /etc/nova/nova.conf_bak[[email  Protected] ~] #vim  /etc/nova/nova.conf[default]rpc_backend = rabbitauth_strategy =  keystonemy_ip = MANAGEMENT_INTERFACE_IP_ADDRESS   #填写本机的管理ip, that's 10.0.0 segment of Use_neutron  = truefirewall_driver = nova.virt.firewall.noopfirewalldriver[oslo_messaging_rabbit] Rabbit_host = controllerrabbit_userid = openstackrabbit_password = rabbit_pass     #填写你rabbit的密码 [keystone_authtoken]auth_uri = http://controller:5000auth_url =  http://controller:35357memcached_servers = controller:11211auth_type =  passwordproject_domain_name = defaultuser_domain_name = defaultproject_name =  serviceusername = novapassword = nova_pass     #填写你nova服务的密码 [VNC] Enabled = truevncserver_listen = 0.0.0.0vncserver_proxyclient_address =  $my _ipnovncproxy_base_url = [glance]api_servers  = http://controller:9292 [oslo_concurrency]lock_path = /var/lib/nova/tmp[libvirt] virt_type = qemu   #在命令行执行egrep  -c  ' (VMX|SVM)  /proc/cpuinfo  if return 0, It's qemu , if it's 1,   is KVM.

Start the Nova-related service and join the boot boot.

[[email protected] ~]# systemctl enable Libvirtd.service Openstack-nova-compute.service[[email protected] ~]# Systemctl Start Libvirtd.service Openstack-nova-compute.service

Second, verification

Executing on the Controller node
