CentOS怎样安装Python3.6

yum install -y openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel
安装可能用到的依赖

wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
下载Python3.6.5源码

tar -xzvf Python-3.6.5.tgz
解压到当前目录

cd Python-3.6.5
进入解压后的目录

./configure --prefix=/usr/local/python
安装到/usr/local/python目录，不用事先创建python目录

make
编译

make install
安装

cd /usr/bin
进入/usr/bin目录

mv python python.bak
mv pip pip.bak
重命名python2的快捷方式

ln -s /usr/local/python/bin/python3.6 /usr/bin/python
ln -s /usr/local/python/bin/pip3.6 /usr/bin/pip
创建python3与pip3软连接

ll yum*
查看/usr/bin目录下有哪些yum文件
把这些文件的第一行#!/usr/bin/python改为#!/usr/bin/python2
因为yum是依赖python的，所以我们修改了默认的python,就要修改yum，让其运行指向python2

修改urlgrabber配置文件
vim /usr/libexec/urlgrabber-ext-down
把第一行#!/usr/bin/python 改为 #!/usr/bin/python2
