服务器python环境配置福利，CentOS ,Linux 一键下载python3和环境配置

很多新手对于linux 系统很是费解，通常下一个环境就需要大半天，中途还会出现各种这样的问题
，干脆写一个脚本一键配置python环境

shell 脚本start.sh：

#!/bin/bash
yum -y groupinstall "Development tools"
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
yum install -y libffi-devel zlib1g-dev
yum -y install mesa-libGL.x86_64
yum install zlib* -y
package_dir=/home/package
if [ ! -d "$package_dir" ]; then
    mkdir $package_dir
fi
  cd $package_dir
yum -y remove python36
yum -y install python36
#which wget || yum -y install wget
#wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tar.xz
#tar -xvf Python-3.7.2.tar.xz
#mkdir /usr/local/python3
#cd Python-3.7.2
#./configure --prefix=/usr/local/python3 --enable-optimizations --with-ssl
#make && make install
ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3

cd ~
mkdir .pip
cd ~/.pip
echo '[global]' >pip.conf
echo 'index-url = https://mirrors.aliyun.com/pypi/simple' >>pip.conf
echo "python3.6 installed"
pip3 install --upgrade pip
pip3 install numpy
pip3 install Pillow
pip3 install bottle
pip3 install scikit-learn
pip3 install opencv-python
#pip3 install -r requirements.txt
