centos--python3安装--django初始化

1 centos7 下 python3的安装

安装脚本如下

#!/bin/bash
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel \
readline-devel tk-devel gcc make gcc gcc-c++ autoconf libjpeg libjpeg-devel \
libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib \
zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses \
ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5-devel libidn \
libidn-devel openssl openssl-devel nss_ldap openldap openldap-devel \
openldap-clients openldap-servers libxslt-devel libevent-devel \
ntp libtool-ltdl bison libtool vim-enhanced pcre libffi-devel
wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tgz
tar -xvf Python-3.8.0.tgz -C /usr/local
mkdir /usr/local/python3;cd /usr/local/Python-3.8.0
./configure --prefix=/usr/local/python3
make && make install
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip

如果在在官网上下载好Python-3.8.0.tgz文件
链接：https://pan.baidu.com/s/1ShpZ6cIngDFluvqut1EIIw
提取码：jpmv
，只需将wget那一行注释掉，将该文件和脚本放在同一文件夹下，执行脚本即可。

2 安装虚拟环境以及Django

安装pipenv

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pipenv

创建并启动虚拟环境

cd /home;mkdir project1 && cd project1
python3 -m venv first_env
. ./first_env/bin/activate

安装django并指定版本
下载慢解决方法
