在Centos7系统中,默认带的Python版本是Python2.7的,部分新的软件需要升级Python到3.x版本.
步骤1、下载Python安装包
wget https://www.python.org/ftp/python/3.10.1/Python-3.10.1.tgz
步骤2、安装Python依赖包
yum install -y libffi-devel
yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc libffi-devel
步骤3、Python安装包解压缩
tar -zxf Python-3.10.1.tgz
步骤4、进入Python-3.10.1文件夹
cd Python-3.10.1
步骤5、执行编译、安装
./configure --prefix=/usr/local/python
make && make install
步骤6、备份Python2版本
mv /usr/bin/python /usr/bin/python.bak
步骤7、创建软连接
ln -s /usr/local/python/bin/python3.10 /usr/bin/python
步骤8、查看Python版本
python -V
步骤9、修改yum配置文件（yum使用python2）
将文件头中的#!/usr/bin/python改为#!/usr/bin/python2
