5.openstack之mitaka搭建计算节点

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ip
vncserver_listen = 192.168.11.103
#下面的为管理ip
vncserver_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ip
my_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ip
vncserver_proxyclient_address = 192.168.11.105
#控制节点管理网络ip
novncproxy_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
+----+------------------+--------------+----------+---------+-------+----------------------------+
