1、安裝eclipse、PyDev插件
html
官方eclipse下載地址:https://www.eclipse.org/downloads/ java
這裏不詳細描述了,先裝java運行環境(若是沒裝,安裝eclipse的過程會自動提示要先裝jre),再裝eclipse就對了。python
安裝PyDev插件:打開eclipse --> Help --> Install New Software;詳情參考這(http://www.pydev.org/manual_101_install.html)git
2、配置Pydev debug
github
配置debug server信息ubuntu
3、遠程調試OpenStack Nova api(nova stop instance的api調用)
vim
一、確保遠程運行nova api服務器有pydevd.py,能夠從本地安裝eclipse的pydev插件目錄下找到(不一樣環境下目錄可能有所不一樣)api
而後拷貝到運行nova api服務器的python路徑下bash
ices-MacBook-Air:~ iceyao$ ls -l /Users/iceyao/.p2/pool/plugins/org.python.pydev_4.5.4.201601292234/pysrc/pydevd.py -rw-r--r-- 1 iceyao staff 60901 Jan 29 20:32 /Users/iceyao/.p2/pool/plugins/org.python.pydev_4.5.4.201601292234/pysrc/pydevd.py
二、其次要保證本地eclipse端也有一份相同代碼,若是在不一樣目錄,能夠使用修改pydevd_file_utils.py文件來實現;若是代碼目錄相同,下面這步就跳過服務器
# 不一樣環境下文件位置可能有所不一樣 ices-MacBook-Air:~ iceyao$ ls -l /Users/iceyao/.p2/pool/plugins/org.python.pydev_4.5.4.201601292234/pysrc/pydevd_file_utils.py -rw-r--r-- 1 iceyao staff 14343 Mar 20 14:50 /Users/iceyao/.p2/pool/plugins/org.python.pydev_4.5.4.201601292234/pysrc/pydevd_file_utils.py ices-MacBook-Air:~ iceyao$ vim /Users/iceyao/.p2/pool/plugins/org.python.pydev_4.5.4.201601292234/pysrc/pydevd_file_utils.py # 找到PATHS_FROM_ECLIPSE_TO_PYTHON PATHS_FROM_ECLIPSE_TO_PYTHON = [ (r'/opt/stack/a/nova', # 本地路徑 r'/opt/stack/nova') # 遠端python process路徑 ]
導入本地/opt/stack/a/nova項目
File --> Import --> General --> Existing Projects into Workspace
三、遠程運行nova api服務器設置斷點
本地eclipse機器開啓debug監聽
登入遠程的devstack環境,進入screen,加上--remote_debug-host 172.16.1.10 --remote_debug-port 12306,從新啓動服務
172.16.1.10:本地安裝eclipse的機器ip
stack@yxb-devstack:/opt/devstack$ /usr/local/bin/nova-api --remote_debug-host 172.16.1.10 --remote_debug-port 12306 & echo $! >/opt/stack/status/stack/n-api.pid; fg || echo "n-api failed to start" | tee "/opt/stack/status/stack/n-api.failure"
stack@yxb-devstack:~/nova$ cat nova/cmd/__init__.py # 上述參數的意義 import eventlet from nova import debugger if debugger.enabled(): # turn off thread patching to enable the remote debugger eventlet.monkey_patch(os=False, thread=False) # 加上上述debug參數後,自動eventlet關閉多線程,否則會出現沒法捕獲到斷電調試的代碼 else: eventlet.monkey_patch(os=False)
設置斷點
stack@yxb-devstack:~/nova$ vim nova/compute/api.py @check_instance_lock @check_instance_host @check_instance_cell @check_instance_state(vm_state=[vm_states.ACTIVE, vm_states.ERROR]) def stop(self, context, instance, do_cast=True, clean_shutdown=True): """Stop an instance.""" import pydevd;pydevd.settrace(host='172.16.1.10', port=12306, stdoutToServer=True, stderrToServer=True,suspend=True) # 斷點處 self.force_stop(context, instance, do_cast, clean_shutdown) stack@yxb-devstack:~/nova$ nova list +--------------------------------------+------+--------+------------+-------------+--------------------------------+ | ID | Name | Status | Task State | Power State | Networks | +--------------------------------------+------+--------+------------+-------------+--------------------------------+ | c04f9a2f-36b3-4104-8c75-5461491aca97 | test | ACTIVE | - | Running | public=2001:db8::3, 172.24.4.3 | +--------------------------------------+------+--------+------------+-------------+--------------------------------+ stack@yxb-devstack:~/nova$ stack@yxb-devstack:~/nova$ nova stop c04f9a2f-36b3-4104-8c75-5461491aca97 # nova客戶端發起請求
本地eclipse機器捕獲到,接下來就能夠進行調試了
