Eclipse + Pydev Remote Debugging OpenStack

First, install Eclipse, Pydev plug-in

official eclipse:https://www.eclipse.org/downloads/

This is not described in detail here, first install the Java operating environment, then install Eclipse is right.

Install the Pydev plugin: Turn on Eclipse---help--and install New software; details refer to this (http://www.pydev.org/manual_101_install.html)

Second, configuration Pydev debug

Configuring Debug Server Information

Third, remote debugging OpenStack Nova API (Nova stop instance API call)

1. Make sure the Nova API server is running remotely, and can be found from the Pydev plugin directory where eclipse is installed locally (the directory may vary under different environments) pydevd.py

Then copy to the Python path running the Nova API server

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 20:32/users/iceyao/.p2/pool/plugins/org.python.pydev_4.5.4.2016012922 34/pysrc/pydevd.py

2, next to ensure that the local eclipse side also has a copy of the same code, if in a different directory, you can use to modify the pydevd_file_utils.py file to achieve

# file locations may vary in different environments 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 14:50/users/iceyao/.p2/pool/plugi ns/org.python.pydev_4.5.4.201601292234/pysrc/pydevd_file_utils.pyices-macbook-air:~ iceyao$ VIM/USERS/ICEYAO/.P2 /pool/plugins/org.python.pydev_4.5.4.201601292234/pysrc/pydevd_file_utils.py # Find Paths_from_eclipse_to_ Pythonpaths_from_eclipse_to_python = [(R '/opt/stack/a/nova ', # Local path R '/opt/stack/nova ') # Remote PYTHON process path ]

Import a local/opt/stack/a/nova project

3. remotely run the Nova API server set breakpoints

Log in to the remote Devstack environment, enter screen, add--remote_debug-host 172.16.1.10--remote_debug-port 12306, restart the service
