新建Python环境变量配置文件：
在宿主用户目录下
vim .pystartup
# Add auto-completion and a stored history file of commands to your Python
# interactive interpreter. Requires Python 2.0+, readline. Autocomplete is
# bound to the Esc key by default (you can change it – see readline docs).
# Store the file in ~/.pystartup, and set an environment variable to point
# to it: “export PYTHONSTARTUP=~/.pystartup” in bash.
import atexit
import os
import readline
import rlcompleter
readline.parse_and_bind(‘tab: complete’)
historyPath = os.path.expanduser(“~/.pyhistory”)
def save_history(historyPath=historyPath):
import readline
readline.write_history_file(historyPath)
if os.path.exists(historyPath):
readline.read_history_file(historyPath)
atexit.register(save_history)
del os, atexit, readline, rlcompleter, save_history, historyPath
设置python 环境变量：
永久生效：
echo “export PYTHONSTARTUP=~/.pystartup” >> /etc/profile
source /etc/profile
验证：
[root@localhost ~]# python27
Python 2.7.9 (default, Jun 29 2016, 16:05:04)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.
