首先明确问题出现原因，是因为openssl版本过低或者不存在

查看openssl安装包，发现缺少openssl-devel包

```

rpm -aq|grep openssl

```

openssl-0.9.8e-20.el5

openssl-0.9.8e-20.el5

yum安装openssl-devel

```

yum install openssl-devel -y

```

查看安装结果

```

rpm -aq|grep openssl

```

openssl-0.9.8e-26.el5_9.1

openssl-0.9.8e-26.el5_9.1

openssl-devel-0.9.8e-26.el5_9.1

openssl-devel-0.9.8e-26.el5_9.1

重新对python3.6进行编译安装，用以下过程来实现编译安装:

```

cd Python-3.6.4

./configure --with-ssl

make

sudo make install

```
