Centos7 安装python3.5.3

使用root用户安装：切换到root用户

su

回车，然后输入密码，切换到root用户。

新建一个脚本，如installPython.sh

#!/bin/bash
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

wget https://www.python.org/ftp/python/3.5.3/Python-3.5.3.tgz

mkdir /usr/local/python3
tar -zxvf Python-3.5.3.tgz
cd Python-3.5.3
./configure --prefix=/usr/local/python3
make && make install

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

pip3 -V
python3 -V

改变脚本的权限，为其加上执行权限

例如： chmod u+x installPython.sh 

使用root用户执行这个脚本： ./installPython.sh
