安裝 Python3
首先安裝依賴包
yum -y groupinstall "Development tools"
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
下載 Python3.6.2
wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz
新建文件夾，將軟件放在 python3 下 mkdir /usr/local/python3
然後解壓壓縮包，進入該目錄，安裝 Python3
tar -xvJf Python-3.6.2.tar.xz
cd Python-3.6.2
./configure --prefix=/usr/local/python3
make -j && make install
創建軟鏈接
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
