1. 安裝依賴環境
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 Python 3.6.5
wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
3. 創建安裝目錄
mkdir -p /usr/local/python3
4. 解壓文件
tar -zxvf Python-3.6.5.tgz
5. 編譯安裝
cd Python-3.6.5
./configure --prefix=/usr/local/python3 make make install
6. 建立Python3 的軟連接
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
7. 並將/usr/local/python3/bin加入PATH
vim ~/.bash_profile
修改以下代碼：
PATH=$PATH:$HOME/bin:/usr/local/python3/bin
使用以下命令，使修改生效：
source ~/.bash_profile
8. 檢查是否安裝完成
python3
出現以下代碼表示安裝完成：
