P：

1、安装依赖环境

yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

2、下载python包

wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz

3、解压包，进入文件夹

tar -zxf Python-3.6.6.tgz

cd Python-3.6.6

4、用户配置，指定安装目录

./configure --prefix=/usr/local

如果配置失败，缺少gcc编译环境

yum -y install gcc gcc-c++

5、编译安装python

make

make altinstall

6、修改python链接

cd /usr/bin/

mv python python.backup 重命名

ln -s /usr/local/bin/python3.6 /usr/bin/python

ln -s /usr/local/bin/python3.6 /usr/bin/python3.6

ln -s /usr/local/bin/pip3.6 /usr/bin/pip

7、修改yum文件配置

cd /usr/bin/

ls yum*

vim yum ....

vim /usr/libexec/urlgrabber-ext-down

修改所有文件头部信息 #!/usr/bin/python 为 #!/usr/bin/python2
