linux环境快速编译安装python3.6

一.下载python3源码包

cd /tmp/
wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tgz

二.下载python3编译的依赖包(复制粘贴）

yum install 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 -y

#gcc :c编译器
#python-devel    python 开发包
#openssl-devel     用于pythn的ssl模块
#sqlite-devel     轻量级数据库

三 解压

tar -xvf Python-3.6.2.tgz 

四 进入源码包

cd  Python-3.6.2

五 编译且安装

1 指定安装目录

./configure --prefix=/opt/python/
            --prefix 这个参数 是制定一个安装路径    /opt/python36/bin/python

2 编译并安装

make & make install 

六 配置python3的环境变量

1 获取python3的解析器的位置

/opt/python/bin  

2 获取系统环境变量

$PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/root/bin

3 读取配置文件/etc/profile

vim /etc/profile
PATH=/opt/python/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
