解决CentOS下python3系列缺少SSL模块的方法

在centos7上安装python3.7，很多时候提示缺少安装_ssl模块，这导致很多依赖于ssl的模块无法正常安装，如ulib3，requests.解决方法：先安装编译器和依赖

yum -y install gcc

yum -y install bzip2-devel sqlite-devel openssl-devel readline-devel xz-devel xz-devel tk-devel gdbm-devel

1.下载openssl模块

wget http://www.openssl.org/source/openssl-1.0.2j.tar.gz

2.解压

tar -xzf openssl-1.0.2j.tar.gz

3.编译

./config --prefix=/usr/local/openssl
./config -t
make 
make install

4.配置python

cd Python-3.6.1 #进入python安装目录
./configure --with-ssl #配置ssl模块

5.测试ssl是否正常
