python在使用时,可能会使用ssl模块。所以在编译时,可以直接将ssl模块编译进去。
yum install openssl
yum install openssl-devel -y
cd Python-3.6.6
vi Modules/Setup #修改文件如下
    # Socket module helper for socket(2)
    _socket socketmodule.c
    # Socket module helper for SSL support; you must comment out the other
    # socket line above, and possibly edit the SSL variable:
    SSL=/usr/local/ssl
    _ssl _ssl.c         -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl         -L$(SSL)/lib -lssl -lcrypto
然后进行编译安装即可原文:http://blog.51cto.com/13649299878/2318101
