Unable to establish SSL connection.

二，原因：

wget 报错 Unable to establish SSL connection 通常是由于 客户端与服务器之间的 TLS 版本不匹配、系统缺少 CA 根证书 或 服务器证书过期/自签名 导致的。

三，解决：

 --no-check-certificate 参数跳过 SSL 校验

# wget --no-check-certificat https://files.phpmyadmin.net/phpMyAdmin/5.2.3/phpMyAdmin-5.2.3-all-languages.zip
