centos7安装python3

一、安装所需工具

1 先切换到root用户

su root

2 为确保安装过程不报错，提前安装全部依赖

1 yum install zlib* -y
2 yum install -y libffi-devel zlib1g-dev
3 yum -y groupinstall "Development tools"
4 yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

3 更新gcc版本

1 yum install centos-release-scl
2 yum install devtoolset-7-gcc devtoolset-7-gcc-c++
3 echo "source /opt/rh/devtoolset-7/enable" >>/etc/profile

二、安装python3（以3.8.0为例）

1 下载安装包

wget https://mirrors.huaweicloud.com/python/3.8.0/Python-3.8.0.tar.xz

2 解压

tar -xvJf  Python-3.8.0.tar.xz

3 创建安装目录

mkdir /usr/local/python3

4 安装

这一步时间较长

1 cd Python-3.8.0
2 ./configure --prefix=/usr/local/python3 --enable-optimizations --with-ssl
3 make && make install

5 创建软链接

1 ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
2 ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3

6 查看版本

1 python3 -V
2 pip3 -V
