python3.7、python3.8安装， 解决pip is configured with locations that require TLS/SSL问题

问题：

[root@localhost bin]# pip3 install mysqll
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting mysqll

You are using pip version 19.0.3, however version 19.3.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

百度上面一大堆，全是抄袭，浪费时间！！！！

这个问题是因为openssl的版本太低了！！！

还是看这位大神的吧，他的是3.7遇到的问题，我是在3.8遇到的问题，但是都解决了。
