配置openstack的glance镜像服务时，需要把glance的两个配置文件写入对应的mysql的glance数据库。
在运行su -s /bin/sh -c "glance-manage db_sync" glance命令时报了以下错误。
[root@controller ~]# su -s /bin/sh -c "glance-manage db_sync" glance

oslo_config.cfg.ConfigFileParseError: Failed to parse /etc/glance/glance-api.conf: at /etc/glance/glance-api.conf:5504, Unexpected continuation line: ' flavor = keystone'
这个错误的原因是' flavor = keystone'这一行前面有空格，把空格删除即可。
