rpm -aq|grep openssl
# 缺少openssl-devel
wget
ipm -ivh 
# 各种依赖被需要


#修改Setup文件

vi /root/Python-3.6.5/Modules/Setup.dist

#修改结果如下：

# Socket module helper for socket(2)
_socket socketmodule.c timemodule.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

升级openssl

no module named '_ssl'

# 查看ssl版本
openssl version -a

# python3。6 需要ssl 1.1以上，需要升级openssl

1、下载openssl-1.0.2h.tar.gz

wget https://www.openssl.org/source/openssl-1.0.2h.tar.gz

2、更新zlib

yum install -y zlib

3、解压安装

tar zxf openssl-1.0.2h.tar.gz

cd openssl-1.0.2h

./config shared zlib

make && make install

mv /usr/bin/openssl /usr/bin/openssl.bak

mv /usr/include/openssl /usr/include/openssl.bak

ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl

ln -s /usr/local/ssl/include/openssl /usr/include/openssl

echo “/usr/local/ssl/lib” >> /etc/ld.so.conf

ldconfig -v

# 查看ssl版本 验证
openssl version -a
