下载python3,进行编译安装,运行django程序

在 /opt目录中安装

cd /opt

1.解决python编译安装所需的软件依赖

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

2.下载python3源码包

wget https://www.python.org/ftp/python/3.6.7/Python-3.6.7.tar.xz

xz -d Python-3.6.7.tar.xz

tar -xf Python-3.6.7.tar          #解压缩,生成一个python源码文件夹

3.进入python源码文件夹

cd Python-3.6.7

4.进行编译安装,编译三步

1.第一步
 ./configure --prefix=/opt/python36/
         --prefix  参数解释:指定python36安装的位置

2.第二步
make

3.第三步 ,此时就开始安装python3软件   
make install                    

5.进入python36安装目录 ,检查bin目录

ll -h         

6.配置python3的环境变量  PATH  

1.取出当前的path变量                         
 echo $PATH

2.填写python3的bin目录到PATH中(这步只是准备,不用写入)                  

PATH="/opt/python36/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin"

3.将环境变量,写入到全局配置文件/etc/profile              
 vim  /etc/profile

4.写入如下代码,在最底行写入如下配置                      

PATH="/opt/python36/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin"

5.读取配置文件,加载变量生效                     

source  /etc/profile 

7.安装django,运行django

1.安装django模块

pip3 install -i  https://pypi.douban.com/simple django 
                 
2.升级pip

pip3 install --upgrade pip

3.通过命令创建django项目               

django-admin startproject crm
django-admin startapp app01

关闭防火墙
iptables -F 

安装tree
yum install tree -y
