环境准备

yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel

首先去官网下载python3.6

https://www.python.org/ftp/python/

这里我们下载

yum -y install wget  # 安装wget
wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz

创建python3.6目录

mkdir /usr/local/python3.6

解压python3.6安装包

tar -xzvf Python-3.6.8.tgz

进入解压路径

cd Python-3.6.8

源码安装三个步骤

# 配置(configure)
./configure --prefix=/usr/local/python3.6 --enable-optimizations

# 编译(make)
make

# 安装(make install)
makeinstall

建立软连接

make

makeinstall

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

ln -s /usr/local/python3/bin/pip /usr/bin/pip3.6

加入环境变量

在etc/profile最后一行中加入变量

export PATH="$PATH:/usr/local/python3.6/bin"

python3.6    # 进入python3.6

pip3.6 -V    # 显示pip的版本
