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
#请根据实际情况自行修改my_ip的值
openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 10.130.0.31
openstack-config --set /etc/nova/nova.conf DEFAULT pybasedir /usr/lib/python3/dist-packages
openstack-config --set /etc/nova/nova.conf DEFAULT bindir /usr/bin
openstack-config --set /etc/nova/nova.conf DEFAULT state_path /var/lib/nova
openstack-config --set /etc/nova/nova.conf DEFAULT enabled_apis osapi_compute,metadata
#请根据实际情况自行修改rabbitmq对应服务的ip
openstack-config --set /etc/nova/nova.conf DEFAULT transport_url rabbit://guest:loongson@10.130.0.31:5672
openstack-config --set /etc/nova/nova.conf api auth_strategy keystone
openstack-config --set /etc/nova/nova.conf api_database connection mysql+pymysql://nova:loongson@controller:3306/nova_api
openstack-config --set /etc/nova/nova.conf cinder os_region_name RegionOne
openstack-config --set /etc/nova/nova.conf database connection mysql+pymysql://nova:loongson@controller:3306/nova
openstack-config --set /etc/nova/nova.conf glance api_servers http://controller:9292
openstack-config --set /etc/nova/nova.conf keystone_authtoken www_authenticate_uri http://controller:5000
openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_url http://controller:5000
openstack-config --set /etc/nova/nova.conf keystone_authtoken memcached_servers controller:11211
openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_type password
openstack-config --set /etc/nova/nova.conf keystone_authtoken project_domain_name Default
openstack-config --set /etc/nova/nova.conf keystone_authtoken user_domain_name Default
openstack-config --set /etc/nova/nova.conf keystone_authtoken project_name service
openstack-config --set /etc/nova/nova.conf keystone_authtoken username nova
openstack-config --set /etc/nova/nova.conf keystone_authtoken password loongson
openstack-config --set /etc/nova/nova.conf libvirt virt_type kvm
openstack-config --set /etc/nova/nova.conf libvirt use_virtio_for_bridges true
#如果需要通过iso起虚拟机，需要设置images_type = raw，默认是qcow2
#openstack-config --set /etc/nova/nova.conf libvirt images_type raw
openstack-config --set /etc/nova/nova.conf neutron auth_url http://controller:5000
openstack-config --set /etc/nova/nova.conf neutron auth_type password
openstack-config --set /etc/nova/nova.conf neutron project_domain_name default
openstack-config --set /etc/nova/nova.conf neutron user_domain_name default
openstack-config --set /etc/nova/nova.conf neutron region_name RegionOne
openstack-config --set /etc/nova/nova.conf neutron project_name service
openstack-config --set /etc/nova/nova.conf neutron username neutron
openstack-config --set /etc/nova/nova.conf neutron password loongson
openstack-config --set /etc/nova/nova.conf oslo_concurrency lock_path /var/lib/nova/tmp
openstack-config --set /etc/nova/nova.conf placement region_name RegionOne
openstack-config --set /etc/nova/nova.conf placement project_domain_name Default
openstack-config --set /etc/nova/nova.conf placement project_name service
openstack-config --set /etc/nova/nova.conf placement auth_type password
openstack-config --set /etc/nova/nova.conf placement user_domain_name Default
openstack-config --set /etc/nova/nova.conf placement auth_url http://controller:5000/v3
openstack-config --set /etc/nova/nova.conf placement username placement
openstack-config --set /etc/nova/nova.conf placement password loongson
openstack-config --set /etc/nova/nova.conf vnc enabled true
openstack-config --set /etc/nova/nova.conf vnc server_listen " $my_ip"
openstack-config --set /etc/nova/nova.conf vnc server_proxyclient_address " $my_ip"
openstack-config --set /etc/nova/nova.conf vnc novncproxy_base_url http://controller:6080/vnc_auto.html
3.修改/etc/nova/nova.conf文件，设置 vif_plugging_is_fatal = False 和 vif_plugging_timeout = 0，如下所示：
#Fail instance boot if vif plugging fails
vif_plugging_is_fatal = False
#Number of seconds to wait for neutron vif
#plugging events to arrive before continuing or failing
#(see vif_plugging_is_fatal). If this is set to zero and
#vif_plugging_is_fatal is False, events should not be expected to arrive at all.
vif_plugging_timeout = 0
4.在/etc/httpd/conf.d/00-placement-api.conf增加以下内容，并重启httpd服务， systemctl restart httpd
cp /etc/httpd/conf.d/00-placement-api.conf /etc/httpd/conf.d/00-placement-api.conf.bac
bash
<Directory /usr/bin>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>
Order allow,deny
Allow from all
</IfVersion>
</Directory>5.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;"
#启动计算服并设置开机自启
