一、一键安装脚本

yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make wget libffi-devel
wget http://npm.taobao.org/mirrors/python/3.7.5/Python-3.7.5.tar.xz #下载python3 安装包
tar -xvf Python-3.7.5.tar.xz 
cd Python-3.7.5 
./configure --prefix=/usr/local/python3 #指定安装路径
make && make install     #编译并安装
ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3  #创建软连接
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip    #创建软连接

二、修改pip源

创建pip.conf文件

cd /root/ && mkdir .pip && cd .pip && touch pip.conf

修改pip.conf文件

vi pip.conf

[global]
index-url = https://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host=mirrors.aliyun.com

更新pip到最新版

pip install --upgrade pip

三、验证是否安装成功

验证python3.7 、pip

python3 -V
pip -V
