ERROR: cannot verify mirrors.tuna.tsinghua.edu.cn's certificate, issued by ‘/C=US/O=Let's Encrypt/CN=R3’:
Issued certificate has expired.
To connect to mirrors.tuna.tsinghua.edu.cn insecurely, use `--no-check-certificate'.
我在源码安装mysql时候，访问Tsinghua网站遇到了问题，系统提示我使用--no-check-certificate，这个另一种解决思路就是安装或者更新自己的证书，操作如下
yum install -y ca-certificates
这个时候重新访问Tsinghua，下载mysql的压缩包，结果如下
