问题
I created a Jekyll-powered blog and am hosting it with GitHub Pages.
Now, I want to set up a subdomain (blog.example.com), but can't make it work.
I have added a CNAME file with the text: blog.example.com. And I have added to A records in my Dreamhost account for the subdomain, both pointing to 204.232.175.78, provided by GitHub.
Any idea about what the missing part is, or if I'm doing something incorrectly?
回答1:
The setup is different for domains like example.com and sub-domains like blog.example.com.
In case of a sub-domain: blog.example.com
- Go to Domains | Manage Domains in your webpanel
- Locate
blog.example.com, click Delete in the Actions column - Wait 10 minutes, and then click the DNS link below
example.com - Add a
CNAMErecord:- Name =
blog - Type =
CNAME - Value =
yourusername.github.io.(yes there is a.at the end!)
- Name =
In case of a domain: example.com
- Go to Domains | Manage Domains in your webpanel
- Locate
example.com, click Edit in the Actions column and switch to DNS only hosting (it's at the bottom) - Go back to Domains | Manage Domains in your webpanel
- Click the DNS link below
example.com - Add an
Arecord:- Name = (blank, nothing)
- Type =
A - Value =
185.199.108.153(GitHub, from this page)
- Add a
CNAMErecord:- Name =
www - Type =
CNAME - Value =
yourusername.github.io.(yes there is a.at the end!)
- Name =
(Yes, you need both the A and CNAME records in this case.)
Btw, the only reason I know this is because I did the same thing last weekend. I was quite lost, but the helpful support guys helped me half way, and I figured out the rest. This procedure works for me, I needed both cases so I tested both.

Because of the way DNS records are cached across the internet, these sorts of changes can take a few hours to take effect. It looks like the address you provided resolves correctly now.
