centos7安装python3.6.6

各版本下载地址：https://www.python.org/ftp/python/

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

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

3、解压

tar -zxf Python-3.6.6.tgz
cd Python-3.6.6

4、配置

./configure --prefix=/usr/bin/python3.6.6

报错：configure: error: no acceptable C compiler found in $PATH
原因是本机缺少gcc编译环境，安装即可：

make && make install

6、配置软连接，测试

ln -s /usr/bin/python3.6.6/bin/python3 /usr/bin/python3
python3 -V

7、 配置pip
