系统环境:centos 7.6

Python 版本:Python-3.6.8

1. 环境依赖

Python3.x 的安装需要依赖这四个组件:gcc, zlib,zlib-devel,openssl-devel;所以需要预先安装,命令如下:

yum install gcc -y
yum install zlib -y
yum install zlib-devel -y
yum install openssl-devel -y

2. 下载编译

Python 源码包下载地址: https://www.python.org/downloads/

# wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz

3. 解压编译

# tar -zxvf Python-3.6.8.tgz

进入根目录进行编译,可以指定编译安装的路径,这里我们指定为 /usr/app/python3.6

# cd Python-3.6.8
# ./configure --prefix=/usr/app/python3.6
# make && make install

4. 环境变量配置

vim  /etc/profile
export PYTHON_HOME=/usr/app/python3.6
export  PATH=${PYTHON_HOME}/bin:$PATH

使得配置的环境变量立即生效:

source /etc/profile

5. 验证安装是否成功

输入 python3 命令,如果能进入 python 交互环境,则代表安装成功:

[root@hadoop001 app]# python3
Python 3.6.8 (default, Mar 29 2019, 10:17:41)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-36)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> 1+1

>>> exit()
[root@hadoop001 app]#
