centos 安装python3.6

环境准备

yum -y update
yum install -y openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel gcc gcc-c++ automake autoconf libtool make

首先去官网下载python3.6

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

创建python3.6目录

mkdir /usr/local/python3.6
cd /usr/local/python3.6

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

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

# 编译(make)
make

# 安装(make install)
make altinstall

./configure --prefix=/usr/local/python3.6 && make && make install

建立软连接

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

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

加入环境变量

在vim /etc/profile最后一行中加入变量

export PYTHON_HOME=/usr/local/python3.6
export PATH=$PYTHON_HOME/bin:$PATH
# 使环境变量生效
source /etc/profile

检测是否安装成功

python3.6    # 进入python3.6

pip3.6 -V    # 显示pip的版本
