Ubuntu搭建Openstack平台（kilo）(四.nova)

一.nova环境
参考文档：http://www.aboutyun.com/thread-13089-1-1.html
http://docs.openstack.org/mitaka/install-guide-ubuntu/nova-controller-install.html
1.创建nova数据库并授权

• 创建

mysql -u root -pCREATE DATABASE nova;

• 授权(自己设定密码，连接数据库时用，我的nova)

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

• 退出

exit

2.生效admin用户名

source admin-openrc.sh

3.创建认证服务

• 创建nova用户

openstack user create --password-prompt novaUser Password:(我的设置nova)Repeat User Password:+-----------+----------------------------------+| Field     | Value                            |+-----------+----------------------------------+| domain_id | e0353a670a9e496da891347c589539e9 || enabled   | True                             || id        | 8c46e4760902464b889293a74a0c90a8 || name      | nova                             |+-----------+----------------------------------+

• 添加admin 角色到nova用户

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

• 创建nova 服务实例

 openstack service create --name nova --description "OpenStack Compute" compute +-------------+----------------------------------+| Field       | Value                            |+-------------+----------------------------------+| description | OpenStack Compute                || enabled     | True                             || id          | 060d59eac51b4594815603d75a00aba2 || name        | nova                             || type        | compute                          |+-------------+----------------------------------+

• 创建nova的API endpoint

openstack endpoint create \--publicurl http://controller:8774/v2/%\(tenant_id\)s  \--internalurl http://controller:8774/v2/%\(tenant_id\)s  \--adminurl http://controller:8774/v2/%\(tenant_id\)s \--region RegionOne compute+--------------+-----------------------------------------+| Field        |Value                                    |+--------------+-----------------------------------------+| adminurl     |http://controller:8774/v2/%\(tenant_id\)s|| id           |3c1caa473bfe4390a11e7177894bcc7b         || internalurl  |http://controller:8774/v2/%\(tenant_id\)s|| publicurl    |http://controller:8774/v2/%\(tenant_id\)s|| region_id    |RegionOne                                || service_id   |e702f6f497ed42e6a8ae3ba2e5871c78         || service_name |nova                                     || service_type |compute                                  |+--------------+-----------------------------------------+

二.安装Nova

1.控制节点

• 安装nova包

   apt-get install nova-api nova-cert nova-conductor nova-consoleauth nova-novncproxy nova-scheduler python-novaclient -y

• 修改配置文件

vim /etc/nova/nova.conf[DEFAULT]verbose = Truerpc_backend = rabbitauth_strategy = keystone#使用控制节点管理网络ip地址配置my_ip my_ip = 10.0.0.11#使用控制节点管理网络ip地址配置 VNC proxy（不懂是什么）vncserver_listen = 10.0.0.11vncserver_proxyclient_address = 10.0.0.11[database]connection = mysql://nova:NOVA_DBPASS(nova的数据库密码）@controller/nova[oslo_messaging_rabbit]#配置RabbitMQ 消息队列服务rabbit_host = controllerrabbit_userid = openstackrabbit_password = RABBIT_PASS（密码为创建的消息中间件密码，我的为123）[keystone_authtoken]auth_uri = http://controller:5000auth_url = http://controller:35357auth_plugin = passwordproject_domain_id = defaultuser_domain_id = defaultproject_name = serviceusername = novapassword = NOVA_PASS（我的密码为nova）[glance]# 配置镜像服务位置host = controller[oslo_concurrency]lock_path = /var/lib/nova/tmp

• 同步数据库（同步之后，可以看看数据库中是否存在表，有则成功，没有则表明可能sqlite数据库没删，删除后在同步rm -f /var/lib/nova/nova.sqlite）

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

• 重启nova服务

service nova-api restartservice nova-cert restartservice nova-consoleauth restartservice nova-scheduler restartservice nova-conductor restartservice nova-novncproxy restart

---

2.计算节点

• 安装nova包

apt-get install nova-compute sysfsutils -y

• 修改配置文件

vim /etc/nova/nova.conf[DEFAULT]verbose = Truerpc_backend = rabbitauth_strategy = keystone#MANAGEMENT_INTERFACE_IP_ADDRESS这里是计算节点管理网络ip地址 10.0.0.31（看自己的设置定）my_ip = MANAGEMENT_INTERFACE_IP_ADDRESS#启用和配置remote console 访问（不明觉厉）vnc_enabled = Truevncserver_listen = 0.0.0.0vncserver_proxyclient_address = MANAGEMENT_INTERFACE_IP_ADDRESS(即计算节点管理网络ip地址，我是10.0.0.31）novncproxy_base_url = http://controller:6080/vnc_auto.html(控制台显示，如果不能解析controller，可以写成IP地址）[oslo_messaging_rabbit]#配置RabbitMQ 消息队列服务rabbit_host = controllerrabbit_userid = openstackrabbit_password = RABBIT_PASS（密码为创建的消息中间件密码，我的为123）[keystone_authtoken]auth_uri = http://controller:5000auth_url = http://controller:35357auth_plugin = passwordproject_domain_id = defaultuser_domain_id = defaultproject_name = serviceusername = novapassword = NOVA_PASS（我的密码为nova）[glance]# 配置镜像服务位置host = controller[oslo_concurrency]lock_path = /var/lib/nova/tmp

• 查看计算节点是否支持虚拟机硬件加速

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

如果输出是0，则

vim /etc/nova/nova-compute.conf[libvirt]...virt_type = qemu

• 重启服务（删除Sqlite数据库，rm -f /var/lib/nova/nova.sqlite）

service nova-compute restart

---

三.验证安装（控制节点）

• 加载环境变量

source admin-openrc.sh

• 查看每个服务组件是否起来

nova service-list +--+----------------+----------+--------+-------+-----+----------------------------+|Id| Binary         | Host     |Zone    |Status |State| Updated At                 |+--+----------------+----------+--------+-------+-----+----------------------------+| 1|nova-consoleauth|controller|internal|enabled|up   | 2016-02-09T23:11:15.000000 || 2|nova-scheduler  |controller|internal|enabled|up   | 2016-02-09T23:11:15.000000 || 3|nova-conductor  |controller|internal|enabled|up   | 2016-02-09T23:11:16.000000 || 4|nova-compute    |compute1  |nova    |enabled|up   | 2016-02-09T23:11:20.000000 |+--+----------------+----------+--------+-------+-----+----------------------------+

• 列出 镜像

nova image-list

注意：以前搭建的，可以运行，如果上面写的有一些问题，谢谢指出来。
先写到这里，现在错误应该没有了，后面再加其他东西。
