openstack M版安装 compute(nova)服务篇
配置安装nova compute服务安装controller节点
一、创建nova数据库

# mysql -u root -p
>>CREATE DATABASE nova_api;
>>CREATE DATABASE nova;
>>GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
>>GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
>>GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
>>GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
NOVA_DBPASS改为自己要设置的密码
二、创建服务实体和api接口

#source /root/admin-openrc.sh
# 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
# 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
三、安装nova服务
1
# yum install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxyopenstack-nova-scheduler
编辑nova服务配置文件

# mv /etc/nova/nova.conf/etc/nova/nova.conf_bak
enabled_apis = osapi_compute,metadata
rpc_backend = rabbit
auth_strategy = keystone
my_ip = 10.0.0.11
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova_api#改为自己数据库的密码
connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova #改为自己数据库的密码
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS #改为自己rabbitmq的密码
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = NOVA_PASS #改为自己nova服务的密码
vncserver_listen = $my_ip
vncserver_proxyclient_address = $my_ip
api_servers = http://controller:9292
lock_path = /var/lib/nova/tmp
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
启动服务，并添加到开机启动

# 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
安装compute节点
一、安装nova服务

# yum install openstack-nova-compute

rpc_backend = rabbit
auth_strategy = keystone
my_ip = MANAGEMENT_INTERFACE_IP_ADDRESS#填写本机的管理ip，就是10.0.0段的
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS #填写你rabbit的密码
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = NOVA_PASS #填写你nova服务的密码
enabled = True
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url =
api_servers = http://controller:9292
lock_path = /var/lib/nova/tmp
virt_type = qemu#在命令行执行egrep -c '(vmx|svm)' /proc/cpuinfo 如果返回0，就是qemu 如果是1，就 是kvm
启动nova相关服务，并加入开机启动。

# systemctl enable libvirtd.service openstack-nova-compute.service
# systemctl start libvirtd.service openstack-nova-compute.service
二、验证
在controller节点执行

我的compute2暂时没启动所以是down状态。
出现上面信息表示成功。
