python3

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 -y install wget

在Linux上安装Python3

1. 安装依赖环境
# 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
2.下载Python3
# wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz
3.安装python3

　　我个人习惯安装在/usr/local/python3（具体安装位置看个人喜好）
　　创建目录：
# mkdir -p /usr/local/python3
　　解压下载好的Python-3.x.x.tgz包(具体包名因你下载的Python具体版本不不同⽽而不不同，如：我下载的是Python3.6.1.那我这里就是Python-3.6.1.tgz)

# tar -zxvf Python-3.6.1.tgz


4.进入解压后的目录，编译安装。
（编译安装前需要安装编译器yum install gcc）
# cd Python-3.6.1
# ./configure --prefix=/usr/local/python3  

             (#/usr/local/python3为安装目录)

# make
#make install    

(或者 make && make install)

5.建立python3的软链
# ln -s /usr/local/python3/bin/python3 /usr/bin/python3

6.并将/usr/local/python3/bin加入PATH

# vim ~/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin:/usr/local/python3/bin
export PATH
　　按ESC，输入:wq回车退出。

　　修改完记得执行行下面的命令，让上一步的修改生效：

# source ~/.bash_profile
　　检查Python3及pip3是否正常可用：

# python3 -V
Python 3.6.1
# pip3 -V
pip 9.0.1 from /usr/local/python3/lib/python3.6/site-packages (python 3.6)

7.不行的话尝试创建一下pip3的软链接
# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
