1.一键安装Python脚本

#!/bin/bash  
#这是一个在[Ubuntu16.04.3]上安装python3.5的脚本
#此脚本将会以python3.5取代Ubuntu默认安装的python2.7
#如果，你要是使用python2.7请输入Python2进行相关操作

#python3.5将会被安装到【/usr/local/python3/Python-3.5.4】目录
#【PS】请以【root】用户运行此脚本
echo "----------开始安装python3.5.4版本-----------"

#Python-3.5.4.tar.xz文件->>需要依赖gcc make进行编译与安装

sudo apt-get update && apt-get install -y gcc make

sudo mkdir /usr/local/python3

#sudo  wget http://www.python.org/ftp/python/3.5.4/Python-3.5.4.tar.xz
sudo  wget https://coding.net/u/jamesz2011/p/ubuntu_lib1/git/raw/master/python/Python-3.5.4.tar.xz


sudo tar xvf Python-3.5.4.tar.xz -C /usr/local/python3

cd /usr/local/python3/Python-3.5.4

sudo ./configure --prefix=/usr/local/python3/Python-3.5.4 

make && make install

sudo  /usr/local/python3/Python-3.5.4/bin/python3.5  /usr/local/bin/python3

#sudo update-alternatives --install /usr/local/bin/python3 python /usr/local/python3/Python-3.5.4/bin/python3.5 400

#sudo update-alternatives --config python

sudo chmod a+x ~/.bashrc

#以alias的方式设置python3.5为系统中的默认python版本，alias被写入【~/.bashrc】中
sudo echo "alias python='python3'" >> ~/.bashrc
 

#安装pip工具，并设置pip的源为阿里源
sudo apt-get update && apt-get install -y  python3-pip

#以alias的方式设置python3.5为系统中的默认python版本，alias被写入【~/.bashrc】中
sudo echo "alias pip='pip3'" >> ~/.bashrc



#source ~/.bashrc



#验证当前默认python的版本

#echo "if the versoin of python is v3.5.4----> install ok!!!!"
#python -v
#python3

#pip升级

#pip install --upgrade pip


#设置pip的源为阿里源

echo "sudo pip install --upgrade pip"
echo "sudo pip install turtle --trusted-host mirrors.aliyun.com"
echo "now ,system will restart,please 安装pip阿里源在reboot后"
reboot
