环境：
CentOS Linux release 7.5.1804
python3.7.3
前期准备：
安装相关依赖包，采用 yum 安装.
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 gcc gcc-c++ zlib zlib-devel libffi-devel gcc kernel-devel kenel-headers make bzip2 #相应依赖包 开始安装
解压下载的安装包
tar -xf Python-3.7.3.tgz #解压下载的安装包
cd cd Python-3.7.3 #进入目录
./configure --enable-optimizations #编译检测
make && make install #编译并安装 不出意外的话应该是安装成功的，要是有报错的话需要在看看是否缺少相关依赖包或者是环境变量。
一件下载安装脚本
本脚本从 org 下载安装包，并 yum 安装所有依赖包，自动安装 python3.7.3
wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tgz &&\
tar xf Python-3.7.3.tgz &&\
cd Python-3.7.3 &&\
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 gcc gcc-c++ zlib zlib-devel libffi-devel gcc kernel-devel kenel-headers make bzip2 #相应依赖包 &&\
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 gcc gcc-c++ zlib zlib-devel libffi-devel gcc kernel-devel kenel-headers make bzip2 #防失败执行多一次 &&\
./configure --enable-optimizations &&\
make && make install
