一、创建Nova相关数据库、凭据与API端点

1.创建数据库并授权

#nova-controller先决条件
mysql -uroot -ploongson -e “CREATE DATABASE nova_api;”
mysql -uroot -ploongson -e “CREATE DATABASE nova;”
mysql -uroot -ploongson -e “CREATE DATABASE nova_cell0;”

mysql -uroot -ploongson -e “GRANT ALL PRIVILEGES ON nova_api.* TO ‘nova’@‘localhost’ IDENTIFIED BY ‘loongson’;”
mysql -uroot -ploongson -e “GRANT ALL PRIVILEGES ON nova_api.* TO ‘nova’@‘%’ IDENTIFIED BY ‘loongson’;”

mysql -uroot -ploongson -e “GRANT ALL PRIVILEGES ON nova.* TO ‘nova’@‘localhost’ IDENTIFIED BY ‘loongson’;”
mysql -uroot -ploongson -e “GRANT ALL PRIVILEGES ON nova.* TO ‘nova’@‘%’ IDENTIFIED BY ‘loongson’;”

mysql -uroot -ploongson -e “GRANT ALL PRIVILEGES ON nova_cell0.* TO ‘nova’@‘localhost’ IDENTIFIED BY ‘loongson’;”
mysql -uroot -ploongson -e “GRANT ALL PRIVILEGES ON nova_cell0.* TO ‘nova’@‘%’ IDENTIFIED BY ‘loongson’;”

2.创建计算服务凭据

#以下命令需要输入密码
openstack user create --domain default --password-prompt nova

openstack role add --project service --user nova admin
openstack service create --name nova --description “OpenStack Compute” compute

3.创建compute API服务端点

openstack endpoint create --region RegionOne compute public http://controller:8774/v2.1
openstack endpoint create --region RegionOne compute internal http://controller:8774/v2.1
openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1

二、nova相关软件安装与配置

1.安装nova相关软件

yum install -y openstack-nova-api openstack-nova-conductor openstack-nova-novncproxy openstack-nova-scheduler

2.配置文件修改

cp /etc/nova/nova.conf /etc/nova/nova.conf.bac
openstack-config --set /etc/nova/nova.conf DEFAULT debug true
openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 10.130.0.31

3.同步创建相关数据库（注意顺序）

（1）填充nova-api数据库
su -s /bin/sh -c “nova-manage api_db sync” nova
#验证数据库
mysql -unova -ploongson -e “use nova_api;show tables;”
（2）注册cell0数据库
su -s /bin/sh -c “nova-manage cell_v2 map_cell0” nova
（3）创建cell1单元
su -s /bin/sh -c “nova-manage cell_v2 create_cell --name=cell1 --verbose” nova
（4）初始化nova数据库
su -s /bin/sh -c “nova-manage db sync” nova
（5）检查确认cell0和cell1注册成功
su -s /bin/sh -c “nova-manage cell_v2 list_cells” nova
（6）验证数据库
mysql -unova -ploongson -e “use nova_api;show tables;”
mysql -uplacement -ploongson -e “use placement;show tables;”
