Hôm nay setup 1 cái web server từ linode.
Mình dùng docker nên mọi thứ cũng nhanh, nhưng đến bước cài SSL dùng certbot
Các bước cài chắc mình nói nhanh.
sudo certbot certonly --standalone -d scholling.com -d www.scholling.com
[root@li1772-196 ~]# sudo certbot certonly --standalone -d scholling.com -d www.scholling.com

IMPORTANT NOTES:
- The following errors were reported by the server:
Domain: scholling.com

Error getting validation data
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.
Cách xử lý mình như sau:
- Kiểm tra xem có bị
[root@li1772-196 ~]# firewall-cmd --get-active-zones
docker
interfaces: docker0 br-464f8eeeb454
public
interfaces: eth0
[root@li1772-196 ~]# firewall-cmd --zone=public --add-port=80/tcp --permanent
success
[root@li1772-196 ~]# firewall-cmd --reload
success
Sau đó chạy lại
sudo certbot certonly --standalone -d scholling.com -d www.scholling.com
Kết quả đã tạo OK
