一、CentOS6安装Python 3.6.5
1、安装Python前的库环境
yum install gcc patch libffi-devel python-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel -y yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel readline-devel.x86_64 -y
2、下载Python源码包
cd /opt/ wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
3、 安装Python
tar zxvf Python-3.6.5.tgz cd Python-3.6.5 ./configure --prefix=/usr/local/python3 make && make install
4、设置软连接
ln -s /usr/local/python3/bin/python3.6 /usr/local/bin/python3 ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3
5、查看python3版本以及pip3版本
python3 pip3 -V
6、更新pip3版本
pip3 install --upgrade pip
二、创建虚拟环境
Python自带虚拟环境
1、先在终端进入想要创建的环境的环境目录（venv模块只有python3才有，2没有，故创建的虚拟环境都是python3）
python3 -m venv pyenv1
2、激活虚拟环境
source pyenv1/bin/activate
3、退出虚拟环境
deactivate
三、安装Django
1、安装Django
pip3 install django==1.11
2、给Django设置软连接
ln -s /usr/local/python3/bin/django-admin /usr/local/bin/django-admin
四、安装git
1、安装git
yum install git -y
git init
git status
git add .
