glance架构：
由图可看到glance由三部分组成glance-api、glance-registry，db 1.glance-api是后台运行的进程，对外提供RESTAPI，响应image查询获取和存储的调用，glance-api不会真正的处理请求，端口是9292 2.glance-registry是后台运行的服务进程，负责处理和存储Image的metadata，例如image的大小和类型，这部分数据是存在DB中的。端口是9191 3.DB存储着Image的metadata信息，默认是mysql，端口是3306
配置：

glance遇到问题如何troubleshooting
01.开启debug
[root@master1 log]# grep "debug" /etc/glance/glance-api.conf # The hostname/IP of the pydev process listening for debug connections #pydev_worker_debug_host = <None> #pydev_worker_debug_port = 5678 #debug = false #设置为true即可 #logging_debug_format_suffix = %(funcName)s %(pathname)s:%(lineno)d # Verbosity of SQL debugging information: 0=None, 100=Everything. # Deprecated group/name - [DEFAULT]/sql_connection_debug #connection_debug = 0
02.查看/var/log/glance目录下的日志
