问题描述
问 题
按照文档操作的：https://certbot.eff.org/#cent...
但是下面的命令报错：
[root@test ~]# certbot certonly --webroot -w /var/www/www.example.com -d example.com -d www.example.com
Failed authorization procedure. example.com (http-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://example.com/.well-known/acme-ch
<head><title>404 Not Found</title></head>
<body bgcolor="white">
<center><h1>404 Not Found</h1></center>
<hr><center>", www.example.com (http-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://www.example.com/.well-known/acme-challenge/k
<head><title>404 Not Found</title></head>
<body bgcolor="white">
<center><h1>404 Not Found</h1></center>
<hr><center>"
IMPORTANT NOTES:
- If you lose your account credentials, you can recover through
e-mails sent to example@example.com.
- The following errors were reported by the server:
Domain: example.com
Type: unauthorized
Detail: Invalid response from
http://example.com/.well-known/acme-challenge/wGNv57IGJjHQ9wyzzALktpNaPzfnTtN3m7u3QuO4p40:
"<html>
<head><title>404 Not Found</title></head>
<body bgcolor="white">
<center><h1>404 Not Found</h1></center>
<hr><center>"
Domain: www.example.com
Type: unauthorized
Detail: Invalid response from
http://www.example.com/.well-known/acme-challenge/kFJ0CSuKOdgcT2xmciB4GGNCcnUPoIbpQmA9jOII_Bk:
"<html>
<head><title>404 Not Found</title></head>
<body bgcolor="white">
<center><h1>404 Not Found</h1></center>
<hr><center>"
To fix these errors, please make sure that your domain name was
entered correctly and the DNS A record(s) for that domain
contain(s) the right IP address.
- Your account credentials have been saved in your Certbot
configuration directory at /etc/letsencrypt. You should make a
secure backup of this folder now. This configuration directory will
also contain certificates and private keys obtained by Certbot so
making regular backups of this folder is ideal.域名example.com和 www.example.com`可以正常访问。
在文档中有这样一个note：
Note:
To use the webroot plugin, your server must be configured to serve files from hidden directories. If /.well-known is treated specially by your webserver configuration, you might need to modify the configuration to ensure that files inside /.well-known/acme-challenge are served by the webserver.
不知是不是上面note说的原因，也不知道在哪里修改上面说的配置，请大神帮看看。
解决方案
这个命令里面的参数，是要根据实际情况来的
certbot certonly --webroot -w /var/www/www.example.com -d example.com -d www.example.com/var/www/www.example.com 是你网站在服务器上的目录位置，替换成自己服务器的网站根目录位置www.example.com 和 example.com 要替换成你自己网站的域名，注意要解析到你运行这段命令的服务器上，不然无法验证通过
