linux-Ubuntu14.04-安装python2+/python3+及创建python2 和python3 的虚拟环境

1、安装Python2.+ 和 Python 3.+

先创建安装目录：

sudo mkdir -p /data/project/tools

cd /data/project/tools

下载对应的安装包

sudo wget https://www.python.org/ftp/python/2.7.15/Python-2.7.15.tgz

sudo wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz

apt-get update

sudo apt-get install -y zlib1g zlib1g-dbg zlib1g-dev zlib-bin zlibc zlib-gst

sudo apt-get install -y bison build-essential bzip2 curl flex g++ g++-multilib gcc git gnupg gperf libbz2-dev libc6-dev libcurl3 libdbi-dev libevent-dev libffi-dev libfontconfig1-dev libfreetype6 libgdbm-dev libgl1-mesa-dev libgl1-mesa-glx libicu-dev libjpeg-dev libncurses5-dev libpng-dev libpython-all-dev:amd64 libpython-dev:amd64 libreadline-dev libreadline6 libreadline6-dev libsqlite3-dev libssl-dev libtcl8.6 libtk8.6 libx11-dev libxext-dev libxml2 libxml2-dev libxml2-utils libxslt1-dev libxslt1.1 libxtst-dev openssl perl ruby sqlite sqlite3 tcl tcl-dev tk tk-dev tofrodos tree vim x11proto-core-dev xsltproc zip zlib1g-dev libmysqld-dev

sudo apt-get install -y subversion libsvn-java libsvnkit-java

sudo tar zvxf Python-2.7.15.tgz

sudo rm -rvR /usr/local/lib/python2.7

cd Python-2.7.15

sudo ./configure --prefix=/usr/local --enable-optimizations

sudo make

sudo make install

sudo make clean

cd /data/project/tools

sudo curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

sudo python get-pip.py

sudo pip install virtualenv

tar zvxf Python-3.6.5.tgz

cd Python-3.6.5

sudo ./configure --prefix=/usr/local --enable-optimizations

sudo make

sudo make install

sudo make clean

pip3.6 install --upgrade pip

pip3.6 install wheel virtualenv

2、配置Stock、Chatbot、ChatbotCMS虚拟环境

cd /data/project/

virtualenv -p /usr/local/bin/python2.7 Stock

virtualenv -p /usr/local/bin/python3.6 Chatbot

virtualenv -p /usr/local/bin/python2.7 ChatbotCMS

virtualenv -p /usr/local/bin/python2.7 WeChat

3.# 增加pip源为阿里云

mkdir -p ~/.pip/

vi ~/.pip/pip.conf

内容：

[global]

index-url = http://mirrors.aliyun.com/pypi/simple

[install]

trusted-host=mirrors.aliyun.com

4.更新源

sudo vi /etc/apt/sources.list

内容：

#aliyun
