Let's Encrypt(certbot) 证书续期提示 是否成功！

zhannan

安装了lnmp 1.4，添加了证书！证书安装成功
我手动运行下续期代码： /bin/certbot renew --renew-hook
提示;
[root@localhost ~]#  /bin/certbot renew --renew-hook
/root/.local/share/letsencrypt/lib/python2.6/site-packages/cryptography/__init__.py:26: DeprecationWarning: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of cryptography will drop support for Python 2.6
  DeprecationWarning
usage:
  certbot [SUBCOMMAND] [options] [-d DOMAIN] [-d DOMAIN] ...

Certbot can obtain and install HTTPS/TLS/SSL certificates.  By default,
it will attempt to use a webserver both for obtaining and installing the
cert.
certbot: error: argument --renew-hook: expected one argument

这是出什么问题了？

--renew-hook是选项，你没写具体参数，错误信息里有提示

/bin/certbot renew --renew-hook "/etc/init.d/nginx reload"
