首先去python官网下载python3的源码包,网址:https://www.python.org/

centos7系统安装python3,pip3,django

或者直接wget下载

wget https://www.python.org/ftp/python/3.6.4/Python-3.6.4.tgz

编译之前安装依赖关系

[root@qinhan bin]# yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel lib-devel   ncurses-devel   tk-devel gcc make

释放文件:

tar -xf Python-3.6.4.tgz 

进入目录:

cd Python-3.6.4

配置安装目录,其他选项一般默认即可:

./configure --prefix=/application/python-3.6.4

接下来编译源码:

make

执行安装:

make install

更改默认python链接

[root@Poppy bin]# cd /usr/bin/
[root@Poppy bin]# rm -f python
[root@Poppy bin]# ln -s /application/python-3.6.4/bin/python3 /usr/bin/python
[root@Poppy bin]# ln -s /application/python-3.6.4/bin/pip3 /usr/bin/pip3
[root@Poppy bin]# ln -s /application/python-3.6.4/bin/django-admin /usr/bin/django-admin [root@Poppy bin]# python -V # 大写
Python 3.6.4

安装djang-admin命令

[root@Poppy bin]# pip3 install django
建议通过客户端pycharm编写项目

从python2到python3还要更改yum,不然通过yum安装软件时候会报错

[root@Poppy ~]# vi /usr/bin/yum
[root@Poppy ~]# vi /usr/libexec/urlgrabber-ext-down
