老版本wgetSSL证书配置有误导致出错：
Unable to locally verify the issuer's authority.
To connect to xxx insecurely, use `--no-check-certificate'.
解决办法：
更新证书：
curl -o /etc/ssl/certs/ca-certificates.crt
https://curl.se/ca/cacert.pem
发现/usr/lib/ssl/cert.pem
strace wget
https://ip.sb
设置SSL证书正确的位置
mkdir /usr/lib/ssl/
ln -s /etc/ssl/certs/ca-certificates.crt /usr/lib/ssl/cert.pem
