1.安装依赖包

yum -y install gcc -y
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
注：不要缺少，否则有可能安装python出错，python3.7.0以下的版本可不装 libffi-devel 

2.下载python3.7.5源码，根据需求下载

wget https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz
tar -zxvf Python-3.7.5.tgz
mkdir /usr/local/python3 
cd Python-3.7.5
./configure --prefix=/usr/local/python3
make && make install
ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3.7 /usr/bin/pip3
