1、安裝開發工具包
sudo yum -y groupinstall "Development tools"
2、安裝依賴包
sudo 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 libffi-devel
3、下載python3.7的“源碼”：
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz
4、解壓
tar -xJvf Python-3.7.0.tar.xz
5、用cd命令進入解壓出來的文件夾
cd Python-3.7.0
6、執行編譯程序，並指定路徑，最后共享
./configure --prefix=/usr/local/python3 --enable-shared
7、執行安裝
make && make install
8、配置環境變量（創建python3,pip,軟鏈接，放入/usr/bin下）
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip
9、將編譯目錄下的libpython3.7m.so.1.0文件復制到
cp /root/Python3.7.0/libpython3.7m.so.1.0 /usr/lib64/libpython3.7m.so.1.0
