一、查看CentOS版本
1、查看已安装的CentOS版本信息：
[root@HadoopLinux ~]# cat /proc/version
Linux version 3.10.0-862.14.4.el7.x86_64 (mockbuild@kbuilder.bsys.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) ) #1 SMP Wed Sep 26 15:12:11 UTC 2018
[root@HadoopLinux ~]# uname -a
Linux HadoopLinux 3.10.0-862.14.4.el7.x86_64 #1 SMP Wed Sep 26 15:12:11 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
[root@HadoopLinux ~]# uname -r
3.10.0-862.14.4.el7.x86_64
?
2、查看linux版本：
[root@HadoopLinux ~]# lsb_release -a
LSB Version:?? ?:core-4.1-amd64:core-4.1-noarch
Distributor ID:?? ?CentOS
Description:?? ?CentOS Linux release 7.5.1804 (Core)
Release:?? ?7.5.1804
Codename:?? ?Core
[root@HadoopLinux ~]# cat /etc/issue
\S
Kernel \r on an \m
[root@HadoopLinux ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
?
3、查看系统是64位还是32位:
[root@HadoopLinux ~]# getconf LONG_BIT
64
[root@HadoopLinux ~]# file /bin/ls
/bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=c5ad78cfc1de12b9bb6829207cececb990b3e987, stripped
[root@HadoopLinux ~]# lsb_release -a
LSB Version:?? ?:core-4.1-amd64:core-4.1-noarch
Distributor ID:?? ?CentOS
Description:?? ?CentOS Linux release 7.5.1804 (Core)
Release:?? ?7.5.1804
二、安装python3
1、查看python版本

2、升级Python版本
第一步：安装相关依赖包和编译环境
如果不安装相关依赖包，在使用pip安装python包时会出现找不到SSL错误！
[root@HadoopLinux ~]# 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 gcc
