Openstack-Nova计算服务
教程大纲
1. Nova的服务组件介绍
2. NovaCompute的安装部署
1.创建数据库Nova，Nova_api
mysql -u root -p -e "create database nova;"
mysql -u root -p -e "grant all privileges on nova.* to ‘nova‘@‘localhost‘ identified by ‘nova‘;"
mysql -u root -p -e "grant all privileges on nova.* to ‘nova‘@‘%‘ identified by ‘nova‘;"
mysql -u root -p -e "create database nova_api;"
mysql -u root -p -e "grant all privileges on nova_api.* to ‘nova‘@‘localhost‘ identified by ‘nova‘;"
mysql -u root -p -e "grant all privileges on nova_api.* to ‘nova‘@‘%‘ identified by ‘nova‘;"
2.安装Nova服务组件
yum install openstack-nova-api openstack-nova-conductor \
openstack-nova-console openstack-nova-novncproxy \
openstack-nova-scheduler
3.配置Nova和Nova-api的数据库同步
[api_database]
connection=mysql://nova:[email protected]/nova_api
[database]
connection=mysql://nova:[email protected]/nova
同步数据库
# su -s /bin/sh -c "nova-manage api_db sync" nova
# su -s /bin/sh -c "nova-manage db sync" nova
4.修改配置Nova.conf
[DEFAULT]
my_ip=192.168.100.40
enabled_apis = osapi_compute,metadata
rpc_backend = rabbit Rabbit使用
auth_strategy = keystone 使用keystone认证
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver （使用networking服务，这里是禁用内置防火墙服务 我们使用neutron来）
[oslo_messaging_rabbit] 使用Rabbitmq
rabbit_host=192.168.100.40
rabbit_port=5672
rabbit_userid=openstack
rabbit_password=openstack
[keystone_authtoken] 配置keystone的注册信息
auth_uri = http://192.168.100.40:5000
auth_url = http://192.168.100.40:35357
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = nova
[vnc] 配置Novnc的远程管理访问 （HTML5开的管理控制台）
vncserver_listen=$my_ip
vncserver_proxyclient_address=$my_ip
[glance] 配置glance的api的接口
api_servers = http://192.168.100.40:9292
[oslo_concurrency]锁定配置目录
lock_path = /var/lib/nova/tmp
5.创建Nova的用户
. admin-openrc （1）创建nova用户 openstack user create --domain default --password-prompt nova (2)nova添加admin的角色 openstack role add --project service --user nova admin (3)创建Nova服务实体 openstack service create --name nova --description "OpenStack Compute" compute (4)创建computer的服务api断点 openstack endpoint create --region RegionOne compute public http://192.168.100.40:8774/v2.1/%\(tenant_id\)s openstack endpoint create --region RegionOne compute internal http://192.168.100.40:8774/v2.1/%\(tenant_id\)s openstack endpoint create --region RegionOne compute admin http://192.168.100.40:8774/v2.1/%\(tenant_id\)s
6.设置开机自启动服务
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
7.第二部分创建nova-compute计算节点
openstack user create --domain default --password-prompt glance
将glance 加入服务中
openstack role add --project service --user glance admin
8 .安装计算节点node2 Nova
yum install openstack-nova-compute
9.cp 控制节点上的Nova配置文件到计算节点上
cp /etc/nova/nova.conf 192.168.100.50:/etc/nova.conf
10.修改计算节点Nova的配置文件
my_ip=192.168.100.50
[vnc]
enabled=true
keymap=en-us
vncserver_listen=0.0.0.0
vncserver_proxyclient_address=$my_ip
novncproxy_base_url=http://192.168.100.40:6080/vnc_auto.html
配置支持硬件虚拟化方式
egrep -c ‘(vmx|svm)‘ /proc/cpuinfo
[libvirt]
virt_type = qemu
11.启动服务
# systemctl enable libvirtd.service openstack-nova-compute.service
# systemctl start libvirtd.service openstack-nova-compute.service
13.在控制节点上验证Nova节点的节点
openstack host list
