google app engine path in linux?

I'm starting to learn googleapp engine and use python. Whenever i create a new project, should i always include whole bunch of configuration and python files like these,

abhilas开发者_如何学JAVAh@abhilash:~/python_resources/google_appengine$ ls
appcfg.py  bulkload_client.py  demos             google  LICENSE               README         remote_api_shell.py  tools
BUGS       bulkloader.py       dev_appserver.py  lib     new_project_template  RELEASE_NOTES  templates            VERSION

Can i put the dev_appserver.py and others to /bin/bash, so i could use them whenever i create a project? Or how to setup appengine permanently in my workplace?

A new GAE project doesn't need any of those files.
Per the Getting Started Guide, all you need is app.yaml and main.py.

If your goal is less command-line typing you can add the google_appengine dir to your PATH in your .bashrc, e.g.

export PATH=$HOME/google_appengine:$PATH

You'll also want to create a symlink to python2.5, like so:

ln -s /usr/bin/python2.5 ~/google_appengine/python

Then you can just do this to run your app on the development server:

$ dev_appserver.py /path/to/myapp/

Also it might be useful to add app engine to your python path as well.

Like so for me that I prefer to keep app engine in /usr/local/

export GAE="/usr/local/google_appengine"
export PYTHONPATH="$PYTHONPATH:$GAE"
export PATH="$PATH:$GAE"

This might come in handy if for example you want to use some of the libraries to run tests on an external module source and so on...

If you are using Google Cloud SDK, add this to your ~/.profile (or ~/.bash_profile in OS X):

#!/usr/bin/env bash

export CLOUDSDK_ROOT_DIR="/path/to/google/cloud/sdk/"
export APPENGINE_HOME="${CLOUDSDK_ROOT_DIR}/platform/appengine-java-sdk"
export GAE_SDK_ROOT="${CLOUDSDK_ROOT_DIR}/platform/google_appengine"

# The next line enables Java libraries for Google Cloud SDK
export CLASSPATH="${APPENGINE_HOME}/lib":${CLASSPATH}

# The next line enables Python libraries for Google Cloud SDK
export PYTHONPATH=${GAE_SDK_ROOT}:${PYTHONPATH}

# * OPTIONAL STEP *
# If you wish to import all Python modules, you may iterate in the directory
# tree and import each module.
#
# * WARNING *
# Some modules have two or more versions available (Ex. django), so the loop
# will import always its latest version.
for module in ${GAE_SDK_ROOT}/lib/*; do
  if [ -r ${module} ]; then
    PYTHONPATH=${module}:${PYTHONPATH}
  fi
done
unset module

Add following lines to .bashrc file

export PATH=$PATH:/path/to/google_appengine/
export PYTHONPATH="$PYTHONPATH:/path/to/google_appengine:/path/to/google_appengine/‌​lib/:/path/to/google_appengine/lib/yaml/"
