六、安装Nova服务【VMware虚拟机搭建Openstack+Ironic】

基本说明

提供计算服务，需要安装在控制节点和计算节点。

controller节点

数据库操作

1. 进入数据库

mysql -uroot -p123456

2. 创建nova数据库

CREATE DATABASE nova_api default character set utf8;
CREATE DATABASE nova default character set utf8;
CREATE DATABASE nova_cell0 default character set utf8;

3. 创建用户并授权

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY '123456';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '123456';

GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY '123456';

创建用户以及配置endpoint

1. 激活环境变量

 source /root/source-admin.sh

2.创建用户

openstack user create --domain default --password 123456 nova

3.创建角色并授权

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

4.创建服务

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

5.创建endpoint

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

安装配置nova组件

1. 安装软件

yum -y install openstack-nova-api openstack-nova-conductor openstack-nova-novncproxy openstack-nova-scheduler

2. 修改配置文件

cd /etc/nova/ && mv nova.conf nova.conf.source && cat nova.conf.source |grep -Ev "^#|^$" > nova.conf && chown root:nova nova.conf

vim /etc/nova/nova.conf

[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:123456@controller
my_ip = 10.0.0.11

[api_database]
connection = mysql+pymysql://nova:123456@controller/nova_api

[database]
connection = mysql+pymysql://nova:123456@controller/nova

[api]
auth_strategy = keystone

[keystone_authtoken]
www_authenticate_uri = http://controller:5000/
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 = 123456

[service_user]
send_service_user_token = true
auth_url = https://controller/identity
auth_strategy = keystone
auth_type = password
project_domain_name = Default
project_name = service
user_domain_name = Default
username = nova
password = 123456

[vnc]
enabled = true
server_listen = $my_ip
server_proxyclient_address = $my_ip

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

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

[placement]
region_name = RegionOne
project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://controller:5000/v3
username = placement
password = 123456

[scheduler]
discover_hosts_in_cells_interval = 300

3. 同步nova-api数据库

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

4. 同步cell0数据库

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

5. 创建cell1

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

6. 同步nova数据库

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

7. 验证cell0 和 cell1是否注册正确

su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova

8. 启动服务并设置开机自启动

systemctl enable openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
systemctl restart openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
systemctl status openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

compute节点

安装配置nova组件

1. 安装软件

yum -y install openstack-nova-compute

2. 修改配置文件

cd /etc/nova/ && mv nova.conf nova.conf.source && cat nova.conf.source |grep -Ev "^#|^$" > nova.conf && chown nova:root nova.conf

vim /etc/nova/nova.conf

[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:123456@controller
my_ip = 10.0.0.31

[api]
auth_strategy = keystone

[keystone_authtoken]
www_authenticate_uri = http://controller:5000/
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 = 123456

[service_user]
send_service_user_token = true
auth_url = https://controller/identity
auth_strategy = keystone
auth_type = password
project_domain_name = Default
project_name = service
user_domain_name = Default
username = nova
password = 123456

[vnc]
enabled = true
server_listen = 0.0.0.0
server_proxyclient_address = $my_ip
novncproxy_base_url = http://controller:6080/vnc_auto.html

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

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

[placement]
region_name = RegionOne
project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://controller:5000/v3
username = placement
password = 123456


[libvirt]
#virt_type = kvm
virt_type = qemu

3. 启动并重启服务

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

4. 在controller节点上添加计算节点到数据库

——control节点操作——

openstack compute service list --service nova-compute

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

验证

——controller节点操作——

启动环境变量

source /root/source-admin.sh 

显示所有计算服务

openstack compute service list

显示所有endpoint

openstack catalog list

显示所有镜像

openstack image list

检测cell
