运行certbot --nginx显示错误 Saving debug log to /var/log/letsencrypt/letsencrypt.log The requested nginx plugin does not appear to be installed 查找找不到关键错误。麻烦帮忙看下 [rootcentos ~]# sudo nginx -t nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful [rootcentos ~]# sudo nginx -s reload [rootcentos ~]# yum install certbot -y Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile Package certbot-0.31.0-2.el7.noarch already installed and latest version Nothing to do [rootcentos ~]# certbot --nginx Saving debug log to /var/log/letsencrypt/letsencrypt.log The requested nginx plugin does not appear to be installed

@"MoMo"#p305 ```bash sudo certbot --nginx ```

@"johnniang"#p306 sudo certbot --nginx Saving debug log to /var/log/letsencrypt/letsencrypt.log The requested nginx plugin does not appear to be installed 还是同样的错误，我打开网页，出现了Nginx欢迎页。

@"johnniang"#p306 是不是我的域名没有备案造成的？还是其他有错误？

@"[未知用户]"#p313 看一下错误日志呢。 `/var/log/letsencrypt/letsencrypt.log`

@"MoMo"#p314 尝试安装一下这个呢： ```bash sudo yum install certbot python2-certbot-nginx ```

@"johnniang"#p316 十分感谢。还有个问题就是我绑定邮箱的时候执行certbot --nginx To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA record(s) for that domain contain(s) the right IP address. Additionally, please check that your computer has a publicly routable IP address and that no firewalls are preventing the server from communicating with the client. If you're using the webroot plugin, you should also verify that you are serving files from the webroot path you provided. 我查看了我的腾讯云主机和我的网址解析检测都是可以的。出现了这个问题，哪里出现了问题了呢。。。我的主机记录记录 @ 记录类型 A 线路类型默认记录值是我的公网IP地址

@"MoMo"#p319 出现这个错误的原因，可能是 nginx 没有正确配置。

@"MoMo"#p319 可以看一下你的 `nginx` 的配置么？

@"johnniang"#p320 谢谢，我重新安装系统，然后按照步骤一步一步来。最后没有使用Nginx来配置，使用了Caddy，没有出现任何问题。值得注意的是在修改Caddy的配置文件(Caddyfile.conf)的时候填写的邮件地址必须是halo注册的邮件地址。还有个小问题，没有备案的网址打开是欢迎nginx。使用端口可以配置halo是正确的吗？

@"MoMo"#p327 没有备案的话，应该会被云服务提供商阻断吧。

nginx安装成功，certbot --nginx 错误

MoMo halo注册的邮件是什么？您好所有最后用nginx还是没解决吗？
