RT，原本使用的是手动证书，今天改用自动的，然后Nginx就启动失败
重装Nginx也无效

详情：

nginx: [emerg] cannot load certificate "/opt/appnode/agent/data/ssl/piona.cc/piona.cc.crt": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/opt/appnode/agent/data/ssl/piona.cc/piona.cc.crt','r') error:2006D080:BIO routines:BIO_new_file:no such file)
nginx: configuration file /etc/nginx/nginx.conf test failed
