1. 下载python3.6

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

2. 解压缩

 tar -zxvf Python-3.6.4.tgz

mkdir -p /usr/local/python3

3. 安装依赖

yum install openssl openssl-devel

yum install zlib zlib-devel

4. 

vim Modules/Setup

#Socket module helper for SSL support; you must comment out the other
#socket line above, and possibly edit the SSL variable:
SSL=/usr/local/ssl
_ssl _ssl.c 
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl 
-L$(SSL)/lib -lssl -lcrypto

5. 配置

./configure --prefix=/usr/local/python3/ --with-ssl

6. 安装

make && make install 

7. 设置环境变量

cp /root/.bashrc /root/.bashrc.bak

echo 'export PATH="$PATH:/usr/local/python/bin/"' >> /root/.bashrc

8. 创建虚拟环境

virtualenv -p /usr/local/python3/bin/python3.6 py36env  //会在当前的路径下生成一个py36env的文件夹

9. 激活虚拟环境

source /home/work/py36env/bin/activate
