OpenStack Juno系列之計算節點搭建

OpenStack Juno系列之計算節點搭建

nova-compute安裝配置

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

apt-get install nova-compute sysfsutils

編輯配置檔案

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  此處為控制節點管理位址10.0.0.31

vnc_enabled = True

vncserver_listen = 0.0.0.0

vncserver_proxyclient_address = MANAGEMENT_INTERFACE_IP_ADDRESS   此處為控制節點管理位址10.0.0.31

admin_password = NOVA_PASS

[glance]

host = controller

檢視機器是否支援虛拟化如果傳回是0那說明不支援虛拟化則在配置檔案裡面修改為 QEMU

egrep -c '(vmx|svm)' /proc/cpuinfo 

vi /etc/nova/nova-compute.conf

[libvirt]

virt_type = kvm

重新開機服務

service nova-compute restart

删除預設資料庫

rm -f /var/lib/nova/nova.sqlite

執行下變量驗證nova服務是否搭建成功

source admin-openrc.sh
