openstack(Pike 版)集群部署(四)--- Nova 部署

一、介绍

  参照官网部署:https://docs.openstack.org/nova/pike/install/

     继续上一博客进行部署:http://www.cnblogs.com/weijie0717/p/8563294.html

二、部署 Nova-controller 

  1、配置数据库  (任意controller 节点操作)

    # mysql  -uroot -p

    a、创建数据库

      MariaDB [(none)]> CREATE DATABASE nova_api;

      MariaDB [(none)]> CREATE DATABASE nova;

      MariaDB [(none)]> CREATE DATABASE nova_cell0;

    b、创建用户,分配权限      

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';

  2、配置 Nova用户 和API 信息(任意controller 节点操作)

    a、获取管理员认证权限

      #  source admin-openrc

    b、创建用户

      # openstack user create --domain default --password-prompt nova

      

     c、分配 Nova 到 指定project 和 role

       # openstack role add --project service --user nova admin

     d、创建 openstack Nova 服务

      # openstack service create --name nova  --description "OpenStack Compute" compute

      

    e、创建 Nova API (admin,public,internal)

      # 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

       

    f、创建 Placement 用户

      # openstack user create --domain default --password-prompt placement

       

    g、分配 Placement 到 指定project 和 role

      # openstack role add --project service --user placement admin

    h、创建 Placement API (admin,public,internal)

      #  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

       

  3、 Nova 包安装 (所有controller-node)

     #   yum install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler openstack-nova-placement-api -y

  4、修改 nova 配置文件  

    a、# vim  /etc/nova/nova.conf

[DEFAULT]
# ...
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:Nihao.521@controller1:5672,openstack:Nihao.521@controller2:5672,openstack:Nihao.521@controller3:5672
my_ip = 10.6.32.51     #各控制节点配置不同之处
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
osapi_compute_listen=10.6.32.51 #各控制节点配置不同之处
osapi_compute_listen_port=8774

novncproxy_host=10.6.32.51
novncproxy_port=6080



[api_database]
# ...
connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova_api

[database]
# ...
connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova

[api]
# ...
auth_strategy = keystone

[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_PASS

[vnc]
enabled = true
# ...
vncserver_listen = $my_ip
vncserver_proxyclient_address = $my_ip

[glance]
# ...
api_servers = http://controller:9292


[oslo_concurrency]
# ...
lock_path = /var/lib/nova/tmp

[placement]
# ...
os_region_name = RegionOne
project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://controller:35357/v3
username = placement
password = PLACEMENT_PASS

 

    b、#vim /etc/httpd/conf.d/00-nova-placement-api.conf

Listen 10.6.32.51:8778    #修改此处,各控制节点配置不同之处

#最后添加如下行
<Directory /usr/bin>
   <IfVersion >= 2.4>
      Require all granted
   </IfVersion>
   <IfVersion < 2.4>
      Order allow,deny
      Allow from all
   </IfVersion>
</Directory>

 

     c、同步配置文件到其他节点,然后分别修改配置文件不同之处

      # scp /etc/nova/nova.conf root@controller2:/etc/nova/nova.conf

      # scp /etc/nova/nova.conf root@controller3:/etc/nova/nova.conf

      # scp /etc/httpd/conf.d/00-nova-placement-api.conf root@controller2:/etc/httpd/conf.d/00-nova-placement-api.conf

      # scp /etc/httpd/conf.d/00-nova-placement-api.conf root@controller3:/etc/httpd/conf.d/00-nova-placement-api.conf

    d、重启httpd 服务(所有controller节点)

      # systemctl restart httpd

    e、按照官网初始化数据库 (任意控制节点)

      # su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova

      # su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova

      # su -s /bin/sh -c "nova-manage db sync" nova

    f、查看

      #  nova-manage cell_v2 list_cells

        

      #   openstack host list

        

    g、启动服务和开机自启动

      #  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

     h、配置 Haproxy

      博客:http://www.cnblogs.com/weijie0717/p/8530102.html

      更具博客 配置:nova-api  server 、nova novncproxy server 、nova-placement-api  server

三、部署 Nova -computer

  1、包安装 
    # yum install openstack-nova-compute

  2、修改 Nova 配置文件

    #vim /etc/nova/nova.conf     

[DEFAULT]
# ...
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:Nihao.521@controller1:5672,openstack:Nihao.521@controller2:5672,openstack:Nihao.521@controller3:5672 my_ip
= 10.6.32.54 use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver [api] # ... auth_strategy = keystone [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_PASS [vnc] # ... enabled = True vncserver_listen = 0.0.0.0 vncserver_proxyclient_address = $my_ip novncproxy_base_url = http://10.6.32.200:6080/vnc_auto.html [glance] # ... api_servers = http://controller:9292 [oslo_concurrency] # ... lock_path = /var/lib/nova/tmp [placement] # ... os_region_name = RegionOne project_domain_name = Default project_name = service auth_type = password user_domain_name = Default auth_url = http://controller:35357/v3 username = placement password = PLACEMENT_PASS 另外执行以下命令,如果返回值大于0使用默认kvm,如果等于零,需要修改为qemu。 # egrep -c '(vmx|svm)' /proc/cpuinfo [libvirt] # ... virt_type = qemu

 

 

    3、启动服务,并开机自启动

      # systemctl enable libvirtd.service openstack-nova-compute.service

      # systemctl start libvirtd.service openstack-nova-compute.service

     4、添加 computer 节点到 call database. (任意computer 节点运行)

      # source admin-openr

      # openstack compute service list --service nova-compute

      # su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

 四、 验证 (控制节点)

  1、List service components to verify successful launch and registration of each process:

    # openstack compute service list

    

  2、List API endpoints in the Identity service to verify connectivity with the Identity service:

    #  openstack catalog list

    

  3、List images in the Image service to verify connectivity with the Image service:

    # openstack image list

    

  4、Check the cells and placement API are working successfully:

    # nova-status upgrade check

    

 

 完成
