部署nova-controller

1. 部署说明

部署地点： 控制节点（ip:192.168.0.142）。

2. 创建数据库并授权

创建Nova相关数据库、凭据与API端点。

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';"

3. 创建计算服务凭据

以下命令需要输入密码loongson。

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

4. 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

5. 安装nova相关软件

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

6. 配置文件修改

cp /etc/nova/nova.conf /etc/nova/nova.conf.bac

请根据实际情况自行修改my_ip的值。

crudini --set /etc/nova/nova.conf DEFAULT debug true
crudini --set /etc/nova/nova.conf DEFAULT my_ip 192.168.0.142
crudini --set /etc/nova/nova.conf DEFAULT pybasedir /usr/lib/python3/dist-packages
crudini --set /etc/nova/nova.conf DEFAULT bindir /usr/bin
crudini --set /etc/nova/nova.conf DEFAULT state_path /var/lib/nova
crudini --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。

crudini --set /etc/nova/nova.conf DEFAULT transport_url rabbit://guest:loongson@192.168.0.142:5672

crudini --set /etc/nova/nova.conf api auth_strategy keystone

crudini --set /etc/nova/nova.conf placement password loongson

crudini --set /etc/nova/nova.conf vnc enabled true
crudini --set /etc/nova/nova.conf vnc server_listen 192.168.0.142
crudini --set /etc/nova/nova.conf vnc server_proxyclient_address 192.168.0.142
crudini --set /etc/nova/nova.conf vnc novncproxy_base_url http://controller:6080/vnc_auto.html

egrep -v "^#|^$" /etc/nova/nova.conf

输出信息:

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

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
<Directory /usr/bin>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>
Order allow,deny
Allow from all
</IfVersion>
</Directory>

7. 同步创建相关数据库（注意顺序）

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;"

注册cell0数据库。

su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova

创建cell1单元。

su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova

初始化nova数据库。

su -s /bin/sh -c "nova-manage db sync" nova

检查确认cell0和cell1注册成功。

su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova

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。

systemctl enable \
    openstack-nova-api.service \
    openstack-nova-scheduler.service \
    openstack-nova-conductor.service \
    openstack-nova-novncproxy.service
systemctl start \
    openstack-nova-api.service \
    openstack-nova-scheduler.service \
    openstack-nova-conductor.service \
    openstack-nova-novncproxy.service
systemctl status \
    openstack-nova-api.service \
    openstack-nova-scheduler.service \
    openstack-nova-conductor.service \
    openstack-nova-novncproxy.service

创建flavor，内存2048M 虚拟机60G cpu核数2。

nova flavor-create --is-public true boshen_ram_2048_disk_2_vcpus_1 boshen_ram_2048_disk_2_vcpus_1 2048 60 2

验证：

openstack compute service list
openstack catalog list
openstack image list
nova-status upgrade check
