1. 下载python源码至服务器 http://npm.taobao.org/mirrors/python/3.7.5/Python-3.7.5.tgz (根据自己的需要去下载对应的版本)

wget http://npm.taobao.org/mirrors/python/3.7.5/Python-3.7.5.tgz

2. 下载py3编译依赖相关库

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

3. 解压源码编译安装

• 解压源码

tar -zxvf Python-3.7.5.tgz

• 指定安装目录 (这里指定编译文件存放位置为/opt/python37)

cd Python-3.7.5
./configure --prefix=/opt/python37

• 编译、安装

make && make install

4. 创建软连接

ln -s /opt/python37/bin/python3 /usr/bin/python3
ln -s /opt/python37/bin/pip3 /usr/bin/pip3

5. 验证

[root@it bin]# python3 -V
Python 3.7.5
[root@it bin]# 
[root@it bin]# 
[root@it bin]# python3
