openstack-train计算节点安装nova

问题: 计算节点安装nova,因为没有连接到控制节点数据库,所以执行如下步骤会报错

// Discover compute hosts: 
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

文档链接: docs.openstack.org/nova/train/…

解决办法:

// Edit the /etc/nova/nova.conf file and complete the following actions:
[database]
connection = mysql+pymysql://nova:passwd@ip-controller/nova_cell0?charset=utf8

[api_database]
connection = mysql+pymysql://nova:passwd@ip-controller/nova_api?charset=utf8
