RHEL 6 上的 Python-3.8 需要 ssl

我正在使用运行 Linux 6 的旧服务器。我被要求在计算机上安装 aws-CLI，以便我们开始将文件直接保存到 s3 存储桶。这需要 python 3.4 或更高版本（从 2020 年 1 月开始）。

第一次尝试后，我收到以下错误：

# pip3 install awscli --upgrade --user
WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

基本上 SSL 包丢失了。我从 YUM 安装了一些软件包并重新运行./配置、制作、和进行安装并且仍然存在 SSL 模块错误。

在一些帖子和博客的帮助下，我现在能够在看到 SSL 包但未导入的情况下收到此错误。此时我已经能够从源代码安装Python-3.8。在此期间制作过程我看到以下几行。

# ./configure --with-openssl=/usr/src/openssl-1.0.2o --enable-optimizations
# make

Following modules built successfully but were removed because they could not be imported:
_hashlib              _ssl


Could not build the ssl module!
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host().

然后尝试在 Python 中导入该包，我得到以下信息：

python3.8
Python 3.8.0 (default, Oct 17 2019, 10:40:08)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-23)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import ssl
Traceback (most recent call last):

  File "/usr/local/lib/python3.8/ssl.py", line 98, in <module>
    import _ssl             # if we can't import it, let the error propagate
ModuleNotFoundError: No module named '_ssl'
>>> exit()

我可以尝试实现在 RHEL6 上安装 aws-cli 的最终目标吗？请包括我需要清理/卸载当前可能存在的任何混乱的任何步骤。

答案1

openssl我遇到了同样的问题，并通过将库的路径添加到rpath：

LDFLAGS=-Wl,-rpath=/usr/src/openssl-1.0.2o/lib
./configure --with-openssl=/usr/src/openssl-1.0.2o --enable-optimizations
make

您可能会在 IUScommunity 上找到可以安装在 Centos 6 系统上的 Python >3.4 的 rpm。 （Google 获取他们的 URL。）这将绕过尝试从头开始编译 Python 所导致的问题。

除了在过去几个月使用过他们的 yum 存储库之外，我与他们没有任何联系。
