安装python

个人用的系统是CentOS7 里面默认安装了比较老的python2.7

下载最新版python

wget  https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz

如果没有wget，请先安装wget

yum install wget

 解压

tar -xvf Python-3.6.2.tar.xz

[root@VM_58_11_centos ~]# cd Python-3.6.2   定位到文件夹

#查看安装包文件
[root@VM_58_11_centos Python-3.6.2]# ls
