部署计算节点(compute服务)

一:控制节点配置


1.建库建用户


CREATE DATABASE nova_api;

CREATE DATABASE nova;

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'liuyao';

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'liuyao';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'liuyao';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'liuyao';

flush privileges;

2.keystone相关操作


source admin-openrc

openstack user create --domain default \

  --password-prompt nova


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


openstack service create --name nova \

  --description "OpenStack Compute" compute

  

openstack endpoint create --region RegionOne \

  compute public http://controller:8774/v2.1/%\(tenant_id\)s

  

openstack endpoint create --region RegionOne \

  compute internal http://controller:8774/v2.1/%\(tenant_id\)s

  

openstack endpoint create --region RegionOne \

  compute admin http://controller:8774/v2.1/%\(tenant_id\)s

3.安装软件包:


yum install openstack-nova-api openstack-nova-conductor \

  openstack-nova-console openstack-nova-novncproxy \

  openstack-nova-scheduler -y

4.修改配置:


vim /etc/nova/nova.conf


[DEFAULT]

enabled_apis = osapi_compute,metadata

rpc_backend = rabbit

auth_strategy = keystone

my_ip = 192.168.11.103

use_neutron = True

firewall_driver = nova.virt.firewall.NoopFirewallDriver



[api_database]

connection = mysql+pymysql://nova:liuyao@controller/nova_api


[database]

connection = mysql+pymysql://nova:liuyao@controller/nova


[oslo_messaging_rabbit]

rabbit_host = controller

rabbit_userid = openstack

rabbit_password = liuyao


[keystone_authtoken]

auth_url = http://controller:5000

memcached_servers = controller:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = nova

password = liuyao


[vnc]

#下面的为管理

ipvncserver_listen = 192.168.11.103

#下面的为管理

ipvncserver_proxyclient_address = 192.168.11.103


[oslo_concurrency]

lock_path = /var/lib/nova/tmp

5.同步数据库:(此处会报一些关于future的问题,自行忽略)


su -s /bin/sh -c "nova-manage api_db sync" nova

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

6.启动服务


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

二:计算节点配置


1.安装软件包:


yum install openstack-nova-compute libvirt-daemon-lxc -y

2.修改配置:


vim /etc/nova/nova.conf


[DEFAULT]

rpc_backend = rabbit

auth_strategy = keystone

#计算节点管理网络

ipmy_ip = 192.168.11.105

use_neutron = True

firewall_driver = nova.virt.firewall.NoopFirewallDriver


[oslo_messaging_rabbit]

rabbit_host = controller

rabbit_userid = openstack

rabbit_password = liuyao


[vnc]

enabled = True

vncserver_listen = 0.0.0.0#计算节点管理网络ipvncserver_proxyclient_address = 192.168.11.105#控制节点管理网络ipnovncproxy_base_url = http://192.168.11.103:6080/vnc_auto.html


[glance]

api_servers = http://controller:9292


[oslo_concurrency]

lock_path = /var/lib/nova/tmp

3.如果在不支持虚拟化的机器上部署nova,请确认


egrep -c '(vmx|svm)' /proc/cpuinfo结果为0

则编辑/etc/nova/nova.conf

[libvirt]

virt_type = qemu

4.启动服务


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

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

三:验证


控制节点


 source admin-openrc

 openstack compute service list
