“哈喽，大家好，我是C&JJ。这篇文章是第一次发博客，分享的内容是是linux系统下安装Python3”。
Linux下安装Python3。 
警告：图标请不要盗用，谢谢！
to首先简单说下：python2与python3的区别。
1、不等于<>比较运算符，python3不识别，python2.7中!=和<>都能运行。
2、print函数的使用，python3必须加括号，python2加不加都行。
3、python2 的默认编码是ASCII，python3的默认编码是UTF-8。
现在我们开始安装Python3.
首先说明我的服务器是买的云服务器，所以是有网络环境的如wget、yum等。如果你的服务器没有的话要提前配置好，以便于后面的安装。
ok现在我们开始
1、第一步我们需要先将python3安装的路径创建好。（由于我装的python3.6版本的所以目录创建为python36，当然你也可以随便命名，But, of course, none of that matters. ）
[root@VM-16-3-centos ~]# mkdir /root/python36
2、用wget下载python3的安装包。（我这里下载的速度很慢（我云服务器是1M带宽），下载速度取决于你的服务器带宽）
[root@VM-16-3-centos ~]# wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz

下载完成后是这样的。

3、把下载好的包给解压。
[root@VM-16-3-centos ~]# tar -xvf Python-3.6.8.tgz.1
[root@VM-16-3-centos ~]# ll

-rw-r--r-- 1 root root 18479 Aug 18 11:46 wget-log
[root@VM-16-3-centos ~]#
4、把安装python3需要的依赖包用yum下载下来。
[root@VM-16-3-centos ~]# 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

Complete!

5、解压后的python3包移动到python36目录下。（要清楚cp与mv的区别）
[root@VM-16-3-centos ~]# ll
total 4437992
-rw-r--r-- 1 root root 4521459712 Aug 10 20:57 CentOS-7-x86_64-DVD-1708.iso
drwxr-xr-x 2 root root 4096 Aug 18 11:22 python36
drwxr-xr-x 17 501 501 4096 Dec 24 2018 Python-3.6.8
-rw-r--r-- 1 root root 23010188 Dec 24 2018 Python-3.6.8.tgz.1
-rw-r--r-- 1 root root 18479 Aug 18 11:46 wget-log
[root@VM-16-3-centos ~]# mv Python-3.6.8 python36/
[root@VM-16-3-centos ~]# cd python36/
[root@VM-16-3-centos python36]# ll
total 4
drwxr-xr-x 17 501 501 4096 Dec 24 2018 Python-3.6.8
[root@VM-16-3-centos python36]#
6、进入目录进行配置、编译和安装。（配置、编译和安装我没有明细出来，因为是在是太多，跑的也很慢。编译和安装可以一起命令是make && make install ，我这里没有一起用。）
[root@VM-16-3-centos Python-3.6.8]# ./configure --prefix=/root/python36 ##配置python3安装路径
[root@VM-16-3-centos Python-3.6.8]# make ##编译
[root@VM-16-3-centos Python-3.6.8]# make install ##安装
7、添加软连接。（我们设置软链接，直接让新安装的python3.6指向给 /usr/bin/python3 ，让 pip3 指向给/usr/bin/pip3)
[root@VM-16-3-centos Python-3.6.8]# ln -s /root/python36/bin/python3.6 /usr/bin/python3
[root@VM-16-3-centos Python-3.6.8]# ln -s /root/python36/bin/pip3 /usr/bin/pip3
8、最后的验证工作。（先查看下版本信息，后创建一个简单的python脚本做验证）
[root@VM-16-3-centos Python-3.6.8]# python3 --version ##查看python版本信息
Python 3.6.8
[root@VM-16-3-centos Python-3.6.8]# vi CJJ.py ##编辑一个python脚本文件注意文件结尾要以.py结尾
#!/usr/bin/python ##指定解释器
# -*- coding: UTF-8 -*- ##指定编码，我下面输出内容有中文，所以需要指定下UTF-8
print( "你好，世界,我是CJJ." ) ##python3和python2的语法格式要区分
：wq!
[root@VM-16-3-centos Python-3.6.8]# python CJJ.py ##执行.py结尾文件
你好，世界,我是CJJ. ##输出内容
ok，已经结束了，该说再见了。相信你通过以上信息，应该已经学会了python3的安装，让我们下次见。
C&JJ
