问题点

在手动上传镜像的时候：出现错误

Could not parse rfc1738 URL from string 'mysql+pymysql=http://glance:glance@controller/glance'

查看错误应该是配置文件配错了 

查看/etc/glance/glance-api.conf (红色标记的地方为错误点)

connection = mysql+pymysql=http://glance:glance@controller/glance

改为：

connection = mysql+pymysql://glance:glance@controller/glance

期间还遇到一个问题(查看glance 的api.log)：

 u"Table 'glance.images' doesn't exist"

 ProgrammingError: (pymysql.err.ProgrammingError) (1146, u"Table 'glance.images' doesn't exist") 
[SQL: u'INSERT INTO images (created_at, updated_at, deleted_at, deleted, id, name, disk_format, 
container_format, size, virtual_size, status, visibility, checksum, min_disk, min_ram, owner, protected)

'size': None}]

上面的错误一看就可以推断是数据库里没有创建相应的表，所以只需要执行同步数据库的操作就可以了。

su -s /bin/sh -c "glance-manage db_sync" glance

查看相应的表：

MariaDB [glance]> show tables;

再次测试上传，问题解决
