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。
2.keystone
3.glance
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:

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
