目的：在另外一臺不能訪問外網的同版本ubuntu機器上安裝Python2.7環境和相關庫

測試環境：Ubuntu14.04

步驟：

1.安裝好Python2.7並安裝你的專案執行所依賴的庫。

2.抽取python2.7相關檔案和目錄,get_py27.sh:

#!/bin/bash

mkdir  py27x64_u14

cd py27x64_u14

cp /usr/bin/python ./

cp -r /usr/lib/python2.7 ./usr_lib_python2.7 

cp -r /usr/local/lib/python2.7 ./usr_local_lib_python2.7

#某些通過apt install安裝的庫會放到這裡，比如：apt install python-mysqldb

cp  /usr/lib/x86_64-linux-gnu/libmysqlclient.so.18 ./usr_lib_x86_64-linux-gnu/ 

3.打包這個資料夾，複製到目標機

4.初始化python2.7環境，init_python_env.sh:

#!/bin/bash

basepath=$(cd `dirname $0`; pwd)
echo 當前目錄：$basepath

rm -fr /usr/bin/python
rm -fr /usr/lib/python2.7
rm -fr /usr/local/lib/python2.7

ln -s $basepath/python /usr/bin/python
ln -s $basepath/usr_lib_python2.7 /usr/lib/python2.7
ln -s $basepath/usr_local_lib_python2.7 /usr/local/lib/python2.7

#apt install python-mysqldb。如果是ubuntu16，則為libmysqlclient.so.20
ln -s $basepath/usr_lib_x86_64-linux-gnu/libmysqlclient.so.18 /usr/lib/x86_64-linux-gnu/libmysqlclient.so.18  

echo "Python2.7 init OK!"

5.測試通過。

8.缺點：無法使用pip增加額外庫

2018/8/6 補充:

  應該還是可以安裝額外庫的.參考:http://cx-oracle.readthedocs.io/en/latest/installation.html

首先安裝pip,這個應該可以實現綠色移植(待測試): apt install python-pip

然後:

python -m pip install cx_Oracle --upgrade
