安裝nova

在控制節點上執行

controllerHost='controller'
controllerIP='172.31.240.49'
MYSQL_PASSWD='m4r!adbOP'
RABBIT_PASSWD='0penstackRMQ'
NOVA_PASSWD='nova1234!'
PLACEMENT_PASSWD='placement1234!'

1.創建數據庫

mysql -uroot -p${MYSQL_PASSWD} << EOF
     DROP DATABASE IF EXISTS nova;
     CREATE DATABASE nova;
     DROP DATABASE IF EXISTS nova_api;
     CREATE DATABASE nova_api;
     DROP DATABASE IF EXISTS nova_cell0;
     CREATE DATABASE nova_cell0;
     DROP DATABASE IF EXISTS placement;
     CREATE DATABASE placement;
     GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY '${NOVA_PASSWD}';
     GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '${NOVA_PASSWD}';
     GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY '${NOVA_PASSWD}';
     GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY '${NOVA_PASSWD}';
     GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY '${NOVA_PASSWD}';
     GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY '${NOVA_PASSWD}';
     GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY '${PLACEMENT_PASSWD}';

(StrOpt) Set to "host-model" to clone the host CPU feature flags;
to "host-passthrough" to use the host CPU model exactly;
to "custom" to use a named CPU model;
to "none" to not set any CPU model.
If virt_type="kvm|qemu", it will default to "host-model",
otherwise it will default to "none"

(StrOpt) Set to a named libvirt CPU model
(see names listed in /usr/share/libvirt/cpu_map.xml).
Only has effect if cpu_mode="custom" and virt_type="kvm|qemu"
