存儲節點

#第一步 上傳此包，安裝三個依賴(學校網需此步操做，外網直接下一步)

#解壓此包進入後安裝 yum localinstall –y ./*

#下載nova-compute

yum install openstack-nova-compute

#編輯nova配置文件

cd /etc/nova/ cp nova.conf nova.conf.bak vim nova.conf #清空原內容，粘貼以下內容 [DEFAULT] my_ip=#計算節點管理網卡地址 use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver enabled_apis=osapi_compute,metadata transport_url = rabbit://openstack:admin@controller
