一、安装python3.6
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
https://www.python.org/downloads/
|
1
|
# 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：
|
1
|
# 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)
|
1
|
# tar -zxvf Python-3.6.1.tgz
|
4.进入解压后的目录，编译安装。
|
1
2
|
# cd Python-3.6.1
# ./configure --prefix=/usr/local/python3
|
make
|
1
|
# make
|
make install
|
1
|
make install 或者 make && make install
|
5.建立python3的软链
|
1
|
# 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：
|
1
|
# source ~/.bash_profile
|
检查Python3及pip3是否正常可用：
|

|
# python3 -V
Python

# pip3 -V
pip
