OpenStack Juno系列之计算节点搭建
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
