我尝试使用Kubuntu 18在Digital Ocean下为我的php / laravel应用程序设置ssl，如本文所述https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-18-04
但是我在尝试使用certbot获取免费的SSL证书时遇到错误：

products-catalog.nilov-sergey-demo-apps.tk - 这是我在freenom.com上搜索的域名并搜索我发现需要为www子域添加A记录的提示
我试图添加新记录为https://imgur.com/a/ijFxlzN但是试图submit这个页面我得到了：
• Error occured: Invalid value in dnsrecord
怎么了 ？新纪录可以解决我的问题吗？或者我需要以其他方式移动？
apache中的更新＃2配置是：
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html/lprods/public
ServerName products-catalog.nilov-sergey-demo-apps.tk
ServerAlias products-catalog.nilov-sergey-demo-apps.tk
<Directory /var/www/html/lprods/public>
AllowOverride All
Order Deny,Allow
Allow from all

Options FollowSymLinks
DirectoryIndex index.php
ErrorLog /var/www/html/lprods/storage/logs/error.log
CustomLog /var/www/html/lprods/storage/logs/access.log combined
</VirtualHost>
在/ etc / hosts中使用行
138.68.107.5 products-catalog.nilov-sergey-demo-apps.tk
它可以解决我的问题吗？
更新＃3我做了一些更多的评论，然后发现：
我的服务器的IP是138.68.107.4，在ssh下我进入OS的控制台
ssh [email protected]
但在我的/ etc / hosts文件中，我有下一行指向此服务器上的其他主机：
# 127.0.0.1 localhost
127.0.0.1 localhost.localdomain localhost
138.68.107.4 box.example.com box
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
138.68.107.4 votes.nilov-sergey-demo-apps.tk
138.68.107.5 products-catalog.nilov-sergey-demo-apps.tk
138.68.107.6 csvp.nilov-sergey-demo-apps.tk
...
我将最后3行修改为：
138.68.107.4 votes.nilov-sergey-demo-apps.tk
138.68.107.4 products-catalog.nilov-sergey-demo-apps.tk
138.68.107.4 csvp.nilov-sergey-demo-apps.tk
但我仍然不确定这是否是有效值，因为我再次出现下一个错误：
# sudo certbot --apache -d products-catalog.nilov-sergey-demo-apps.tk -d www.products-catalog.nilov-sergey-demo-apps.tk

这个错误的原因是/ etc / hosts中的错误IP还是其他一些问题？
谢谢！
