本篇文章是本系列的第四篇文章，将继续进行OpenStack计算服务的安装 五、安装计算服务

5.1 （控制节点）配置数据库 - 连接数据库

1# mysql -u root -pfuai123 

   创建nova相关数据库并设置访问权限

1MariaDB [(none)]> CREATE DATABASE nova_api;
2MariaDB [(none)]> CREATE DATABASE nova;
3MariaDB [(none)]> CREATE DATABASE nova_cell0;
4
5
6MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \
7  IDENTIFIED BY 'fuai123';
8MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \
9  IDENTIFIED BY 'fuai123';

10 11MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \ 12 IDENTIFIED BY 'fuai123'; 13MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \ 14 IDENTIFIED BY 'fuai123'; 15 16MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' \ 17 IDENTIFIED BY 'fuai123'; 18MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' \ 19 IDENTIFIED BY 'fuai123';

5.3 （控制节点）安装软件包并配置组件 

   安装软件包

1# yum install openstack-nova-api openstack-nova-conductor \ 2 openstack-nova-console openstack-nova-novncproxy \ 3 openstack-nova-scheduler openstack-nova-placement-api -y 

   编辑/etc/nova/nova.conf文件并完成以下配置

1[DEFAULT]
2enabled_apis = osapi_compute,metadata
3transport_url = rabbit://openstack:fuai123@controller
4my_ip = 192.168.0.77
5use_neutron = True
6firewall_driver = nova.virt.firewall.NoopFirewallDriver
7...
8
9[api_database]

10connection = mysql+pymysql://nova:fuai123@controller/nova_api 11... 12 13[database] 14connection = mysql+pymysql://nova:fuai123@controller/nova 15... 16 17[api] 18auth_strategy = keystone 19... 20 21[keystone_authtoken] 22auth_uri = http://controller:5000 23auth_url = http://controller:35357 24memcached_servers = controller:11211 25auth_type = password 26project_domain_name = default 27user_domain_name = default 28project_name = service 29username = nova 30password = fuai123 31... 32 33[vnc] 34enabled = true 35server_listen = $my_ip 36server_proxyclient_address = $my_ip 37... 38 39[glance] 40api_servers = http://controller:9292 41... 42 43[oslo_concurrency] 44lock_path = /var/lib/nova/tmp 45... 46 47[placement] 48os_region_name = RegionOne 49project_domain_name = Default 50project_name = service 51auth_type = password 52user_domain_name = Default 53auth_url = http://controller:35357/v3 54username = placement 55password = fuai123 56... 

   因为软件包的bug，编辑/etc/httpd/conf.d/00-nova-placement-api.conf文件增加如下内容

1<Directory /usr/bin> 2 <IfVersion >= 2.4> 3 Require all granted 4 </IfVersion> 5 <IfVersion < 2.4> 6 Order allow,deny 7 Allow from all 8 </IfVersion> 9</Directory> 

   重启httpd服务

1# systemctl restart httpd 

   导入相关数据库表结构

1# su -s /bin/sh -c "nova-manage api_db sync" nova 2# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova 3# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova 4 5c354ac0-a088-4dbb-b106-e795ebeaec32 6 7# su -s /bin/sh -c "nova-manage db sync" nova 

   验证cell0和cell1是否成功注册


1list_cells 2 3+-------+--------------------------------------+------------------------------------+-------------------------------------------------+ 4| 名称 | UUID | Transport URL | 数据库连接 | 5+-------+--------------------------------------+------------------------------------+-------------------------------------------------+ 6| cell0 | 00000000-0000-0000-0000-000000000000 | none:/ | mysql+pymysql://nova:****@controller/nova_cell0 | 7| cell1 | fc354ac0-a088-4dbb-b106-e795ebeaec32 | rabbit://openstack:****@controller | mysql+pymysql://nova:****@controller/nova | 8+-------+--------------------------------------+------------------------------------+-------------------------------------------------+ 

   设置服务的开机自启动，并启动服务

1# systemctl enable openstack-nova-api.service \ 2 openstack-nova-consoleauth.service openstack-nova-scheduler.service \ 3 openstack-nova-conductor.service openstack-nova-novncproxy.service 4# systemctl start openstack-nova-api.service \ 5 openstack-nova-consoleauth.service openstack-nova-scheduler.service \ 6 openstack-nova-conductor.service openstack-nova-novncproxy.service

5.4 （计算节点）在计算节点安装计算服务 

   安装软件包

1# yum install openstack-nova-compute -y 

   编辑/etc/nova/nova.conf文件并设置如下内容

1[DEFAULT]
2enabled_apis = osapi_compute,metadata
3transport_url = rabbit://openstack:fuai123@controller
4my_ip = 192.168.0.78
5use_neutron = True
6firewall_driver = nova.virt.firewall.NoopFirewallDriver
7...
8
9[api]

10auth_strategy = keystone 11... 12 13[keystone_authtoken] 14auth_uri = http://controller:5000 15auth_url = http://controller:35357 16memcached_servers = controller:11211 17auth_type = password 18project_domain_name = default 19user_domain_name = default 20project_name = service 21username = nova 22password = fuai123 23... 24 25[vnc] 26enabled = True 27server_listen = 0.0.0.0 28server_proxyclient_address = $my_ip 29novncproxy_base_url = http://192.168.0.77:6080/vnc_auto.html 30... 31 32[glance] 33api_servers = http://controller:9292 34... 35 36[oslo_concurrency] 37lock_path = /var/lib/nova/tmp 38... 39 40[placement] 41os_region_name = RegionOne 42project_domain_name = Default 43project_name = service 44auth_type = password 45user_domain_name = Default 46auth_url = http://controller:35357/v3 47username = placement 48password = fuai123 49... 

   检测当前计算节点是否支持硬件虚拟化

我使用的虚拟机，这里返回0，明显我不支持硬件虚拟化

1# egrep -c '(vmx|svm)' /proc/cpuinfo 20 

   编辑/etc/nova/nova.conf文件设置qemu来提供软件虚拟化

1[libvirt] 2virt_type = qemu 3... 

   设置服务的开机自启动，并启动计算服务

1# systemctl enable libvirtd.service openstack-nova-compute.service 2# systemctl start libvirtd.service openstack-nova-compute.service

5.5 （控制节点）向cell数据库添加计算节点 - 添加admin环境变量

1# . admin-openrc 

   执行下面的命令，查看计算节点信息是否已经在数据库

1# openstack compute service list --service nova-compute 2 3+----+--------------+---------+------+---------+-------+----------------------------+ 4| ID | Binary | Host | Zone | Status | State | Updated At | 5+----+--------------+---------+------+---------+-------+----------------------------+ 6| 6 | nova-compute | compute | nova | enabled | up | 2018-04-26T12:00:40.000000 | 7+----+--------------+---------+------+---------+-------+----------------------------+ 

   发现计算节点

1# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova 2 3Found 2 cell mappings. 4Skipping cell0 since it does not contain hosts. 5Getting computes from cell 'cell1': fc354ac0-a088-4dbb-b106-e795ebeaec32 6Checking host mapping for compute host 'compute': 47b0f376-fa1a-4fe8-9f2e-af1be125781a 7Creating host mapping for compute host 'compute': 47b0f376-fa1a-4fe8-9f2e-af1be125781a 8Found 1 unmapped computes in cell: fc354ac0-a088-4dbb-b106-e795ebeaec32
