1、下载Python-3.6.5安装包
在Python官网（https://www.python.org/downloads/）下载对应的安装包，选择3.6.5的linux版本，如下图：
2、将安装包上传至Linux服务器
在Linux服务器根目录下创建目录package，并将安装包上传至该目录下
3、解压Python-3.6.5.tgz
[root@Cherry /]# cd /package/
[root@Cherry package]# tar -zxvf Python-3.6.5.tgz
4、创建Python-3.6.5安装目录
[root@Cherry package]# mkdir /usr/local/python3
5、安装依赖包
[root@Cherry package]# yum install -y gcc
[root@Cherry package]# yum install -y zlib*
[root@Cherry package]# 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 #确保pip的时候不会出错
6、配置安装路径
[root@Cherry package]# cd Python-3.6.5
[root@Cherry Python-3.6.5]# ./configure –prefix=/usr/local/python3 –with-ssl
7、编译
[root@Cherry Python-3.6.5]# make
8、安装
[root@Cherry Python-3.6.5]# make install
9、建立软链接
[root@Cherry Python-3.6.5]# ln -s /usr/local/python3/bin/python3 /usr/bin/python3
[root@Cherry Python-3.6.5]# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
10、增加环境变量
修改配置文件/etc/profile，增加以下内容：
PATH=$PATH:$HOME/bin:
PATH=$PATH:$HOME/bin:/usr/local/python3/bin
执行语句source /etc/profile使环境变量配置立即生效
11、测试安装是否成功
[root@Cherry Python-3.6.5]# python3
