1、安裝依賴
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
2、下載安裝包（可以Windows下載https://www.python.org/downloads/也可以用wget
wget -c https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
下載tgz 包
3、新建一個Python的安裝目錄，mkdir /root/pyrhon36
4、進入tgz包的路徑解壓：tar -vxzf Python-3.6.1.tar.gz
5、解壓完成，cd Python-3.6.1
6、指定Python的安裝路徑 ./configure --prefix=/root/python36
7、make
8、make install
9、因為Linux默認安裝Python2，需要修改軟鏈接：ln -s /root/python36/bin/python3.6 /usr/bin/python
10、修改pip的軟鏈接：ln -s /root/python36/bin/pip3 /usr/bin/pip
11、配置環境變量 vim ~~/.bash_profile 編輯
PATH
=
$PATH:$HOME
/
bin
:
/root/python36/bin
export PATH
ps：修改軟鏈接以后yum 使用報錯，需要修改報錯文件使用Python3
