1、安装python3之前需要先安装一些依赖

yum -y install zlib*  bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel gcc libffi-devel gcc make automake autoconf libtool libffi-devel

2、下载python3.7安装包,请参见https://www.python.org/downloads/source/

3、解压文件

tar -zxvf 下载的文件名

[root@localhost opt]# tar -zxvf Python-3.7.6.tgz 

4、进入Python文件夹目录

cd 解压文件夹名

[root@localhost opt]#  cd Python-3.7.6

5、初始配置

[root@localhost Python-3.7.6]#./configure --prefix=/usr/local/python3

6、安装

[root@localhost Python-3.7.6]# make && make install

7、配置软连接

ln -s /usr/local/python3/bin/python（你安装的版本号） /usr/bin/python3


谨慎操作：ln -s /usr/local/python3/bin/python（你安装的版本号） /usr/bin/python


ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

[root@localhost bin]# ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3
[root@localhost bin]# ln -s  /usr/local/python3/bin/pip3 /usr/bin/pip3

8、验证成功

[root@localhost ~]#  python3 -V
[root@localhost ~]# pip3 -V
