1.控制节点安装

[root@linux-node1 ~]# yum install -y openstack-nova-api openstack-nova-placement-api \

  openstack-nova-conductor openstack-nova-console \

  openstack-nova-novncproxy openstack-nova-scheduler

2.数据库配置

[root@linux-node1 ~]# vim /etc/nova/nova.conf

[api_database]

connection= mysql+pymysql://nova:nova@192.168.56.11/nova_api

[database]

connection= mysql+pymysql://nova:nova@192.168.56.11/nova

3.RabbitMQ配置

[root@linux-node1 ~]# vim /etc/nova/nova.conf

[DEFAULT]

transport_url = rabbit://openstack:openstack@192.168.56.11

4.Keystone相关配置

[root@linux-node1 ~]# vim /etc/nova/nova.conf

[api]

auth_strategy=keystone

[keystone_authtoken]

auth_uri = http://192.168.56.11:5000

auth_url = http://192.168.56.11:35357

memcached_servers = 192.168.56.11:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = nova

password = nova

5.关闭Nova的防火墙功能

[DEFAULT]

use_neutron=true

firewall_driver = nova.virt.firewall.NoopFirewallDriver

6.VNC配置

[root@linux-node1 ~]# vim /etc/nova/nova.conf

[vnc]

enabled=true

server_listen = 0.0.0.0

server_proxyclient_address = 192.168.56.11

7.设置glance

[glance]

api_servers = http://192.168.56.11:9292

8.[oslo_concurrency] 部分,配置锁路径:

[oslo_concurrency]

lock_path=/var/lib/nova/tmp

 

9.设置启用的api

[DEFAULT]

enabled_apis=osapi_compute,metadata

10.设置placement

[placement]

os_region_name = RegionOne

project_domain_name = Default

project_name = service

auth_type = password

user_domain_name = Default

auth_url = http://192.168.56.11:35357/v3

username = placement

password = placement

11.修改nova-placement-api.conf

[root@linux-node1 ~]# 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>

</VirtualHost>

# systemctl restart httpd

12.同步数据库

[root@linux-node1 ~]# su -s /bin/sh -c "nova-manage api_db sync" nova

注册cell0数据库

[root@linux-node1 ~]# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova

13.创建cell1cell

[root@linux-node1 ~]# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova

14.同步nova数据库

[root@linux-node1 ~]# su -s /bin/sh -c "nova-manage db sync" nova

15.验证cell0cell1的注册是否正确

[root@linux-node1 ~]# nova-manage cell_v2 list_cells

16.测试数据库同步情况

[root@linux-node1 ~]#mysql -h 192.168.56.11 -unova -pnova -e " use nova;show tables;"

[root@linux-node1 ~]#mysql -h 192.168.56.11 -unova -pnova -e " use nova_api;show tables;"

17.启动Nova Service

# 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

11.Nova服务注册

# source admin-openstack.sh

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

# openstack endpoint create --region RegionOne compute public http://192.168.56.11:8774/v2.1

# openstack endpoint create --region RegionOne compute internal http://192.168.56.11:8774/v2.1

# openstack endpoint create --region RegionOne compute admin http://192.168.56.11:8774/v2.1

# openstack service create --name placement --description "Placement API" placement

# openstack endpoint create --region RegionOne placement public http://192.168.56.11:8778

# openstack endpoint create --region RegionOne placement internal http://192.168.56.11:8778

# openstack endpoint create --region RegionOne placement admin http://192.168.56.11:8778

验证控制节点服务

[root@linux-node1 ~]# openstack host list

计算节点安装

[root@linux-node2 ~]# yum install -y openstack-nova-compute sysfsutils

[root@linux-node1 ~]# scp /etc/nova/nova.conf 192.168.56.12:/etc/nova/nova.conf

[root@linux-node2 ~]# chown root:nova /etc/nova/nova.conf

1.删除多余的数据配置

2.修改VNC配置

计算节点需要监听所有IP,同时设置novncproxy的访问地址

[vnc]

enabled=true

server_listen = 0.0.0.0

server_proxyclient_address = 192.168.56.12

novncproxy_base_url = http://192.168.56.11:6080/vnc_auto.html

3.虚拟化适配

[root@linux-node2 ~]# egrep -c '(vmx|svm)' /proc/cpuinfo

[libvirt]

virt_type=qemu

如果返回的是非0的值,那么表示计算节点服务器支持硬件虚拟化,需要在nova.conf里面设置

[libvirt]

virt_type=kvm

启动nova-compute

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

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

 

验证计算节点

[root@linux-node1 ~]# openstack host list

计算节点加入控制节点

[root@linux-node1 ~]# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
