[root@controller scripts]# openstack image create "cirros"   --file cirros-0.3.4-x86_64-disk.img   --disk-format qcow2 --container-format bare   --public
出现错误如下"500 Internal Server Error: The server has either erred or is incapable of performing the requested operation. (HTTP 500)"
查看/var/log/glance/api.log注意到如下错误
2016-08-21 09:30:18.343 13311 ERROR glance.common.wsgi [req-c7e5abcd-c6f8-462b-ab1b-4b5b76aad182 f7649ace8e334b18ab41bc469615040a eb048b599fc441b091d9cb
83b893351e - - -] Caught error: (_mysql_exceptions.OperationalError) (1045, "Access denied for user ‘glance‘@‘localhost‘ (using password: YES)")

1检查mysql
show grants for ‘glance‘@‘localhost‘;  
GRANT USAGE ON *.* TO ‘glance‘@‘localhost‘ IDENTIFIED BY PASSWORD ‘********************************‘
确认数据库用户没有问题

2检查 /etc/glance/glance-api.conf
more /etc/glance/glance-api.conf|grep ^[^#]
发现忘记添加下面的数据库连接串
[database]
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance

3修改之后重启服务
systemctl restart openstack-glance-api.service openstack-glance-registry.service

4再次运行
[root@controller scripts]# openstack image create "cirros"   --file cirros-0.3.4-x86_64-disk.img   --disk-format qcow2 --container-format bare   --public
依然报错

5查看/var/log/glance/api.log注意到如下错误

  result = self._query(query)

7然后重启服务
systemctl restart openstack-glance-api.service openstack-glance-registry.service

8再然后运行
[root@controller scripts]# openstack image create "cirros"   --file cirros-0.3.4-x86_64-disk.img   --disk-format qcow2 --container-format bare   --public
