本文在Centos7下本地调试openstack glance代码，之后rmote调试会另写文章说明。

1.首先就是下载和安装openstack glance keystone和一些服务client，这里推荐全装，防止缺少Module。

4.调试

打开pycharm，点击open打开glance文件夹。

以调试glance api为例，我先将断点打在了glance/cmd/api.py 下的\_enforce函数，后台启动api服务：

glance-api --config-file=/etc/glance/glance-api.conf \
    --config-file=/etc/glance/glance-api-paste.ini

pycharm会自动跳到断点，接下去用F5 F6 F7等pycharm快捷键进行调试
