nova-compute安装配置

--------------------

apt-get install nova-compute sysfsutils

编辑配置文件

vi /etc/nova/nova.conf

[DEFAULT]

verbose = True

rpc_backend = rabbit

rabbit_host = controller

rabbit_password = RABBIT_PASS

auth_strategy = keystone

my_ip = MANAGEMENT_INTERFACE_IP_ADDRESS  此处为控制节点管理地址10.0.0.31

vnc_enabled = True

vncserver_listen = 0.0.0.0

vncserver_proxyclient_address = MANAGEMENT_INTERFACE_IP_ADDRESS   此处为控制节点管理地址10.0.0.31

novncproxy_base_url = http://controller:6080/vnc_auto.html

[keystone_authtoken]

auth_uri = http://controller:5000/v2.0

identity_uri = http://controller:35357

admin_tenant_name = service

admin_user = nova

admin_password = NOVA_PASS

[glance]

host = controller

查看机器是否支持虚拟化如果返回是0那说明不支持虚拟化则在配置文件里面修改为 QEMU

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

编辑配置文件

vi /etc/nova/nova-compute.conf

[libvirt]

virt_type = kvm

重启服务

service nova-compute restart

删除默认数据库

rm -f /var/lib/nova/nova.sqlite

执行下变量验证nova服务是否搭建成功

source admin-openrc.sh

nova service-list
