注意事项：该脚本是需要把python的源码压缩包和脚本都放在/opt目录下

#！/bin/bash
# 安装python

echo "----------------开始安装了！----------------"

if [ -e '/opt/Python-3.10.2.tgz' -a -e '/opt/install_python.sh' ]; then
    # 创建安装目录
    mkdir /usr/local/python3
    # 解压压缩包
    tar -zxvf Python-3.10.2.tgz
    # 确认编译环境
    # yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel libffi-devel gcc make
    yum install zlib-devel bzip2-devel openssl openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make readline libffi-devel -y

    if [ -e ~/.pip/pip.conf ]; then
        echo "pip文件以存在。"
    else
        mkdir ~/.pip
        touch ~/.pip/pip.conf
        echo "[global]" >> ~/.pip/pip.conf
        echo "index-url=http://pypi.douban.com/simple" >> ~/.pip/pip.conf
        echo "trusted-host = pypi.douban.com" >> ~/.pip/pip.conf
    fi
    source ~/.bash_profile
    echo "请刷新环境变量：source ~/.bash_profile"
    echo "刷新后直接执行 python3 pip3即可。"

else    
    echo "请确认Python-3.10.2.tgz和脚本已在 /opt 目录下，脚本已退出运行。"
fi

我这边使用的是python-3.10.2.tgz的源码包，如果你们的源码包不同，请进入脚本，修改对应的名字
