How do I redirect a domain to another domain locally?
Solution 1
As Chris already wrote, the problem is that "othersite.dev" is not a number. The format you need is IP hostname1 [hostname2] [hostname3]
.
The deeper problem however is a misunderstanding about the host file and possibly about DNS in general. Basically the host file was not designed for redirections. It was a simple solution back from when CPU cycles where expensive. It lacked features such as the ability to adjust to rapidly changing IP addresses without manually needing to edit a file. These problems were solved by switching from the host file to network based resolver system.
The real answer to your problem therefore is not to use /etc/hosts
, but to use this hierarchical distributed naming system instead. You can do that in several ways. One way is the CNAME as suggested by Chris. Another way would be to give the second server a fixed IP address. Both a real static address, or make a reservation in the DHCP server.
Solution 2
Format of /etc/hosts is "IP" "Hostname" - like 127.0.0.1 localhost
You need a CNAME
in your local DNS server to achieve what you need. You could get the IP of the "othersite.dev" and link it to "testitbeta.dev" like you did with "testitalpha.dev" but when that IP changes you will have to change your /etc/hosts
file as well.
Solution 3
If othersite.com has dynamic IP, but is always accessible by name you have to rely on its registered DNS by always referencing it by name.
Your solution is to make testsitebeta.dev a redirecting URL for othersite.com.
ServerName testsitebeta.dev Redirect / http://othersite.com
This way othersite.com always works (not breaking it with bad host entry) and testsitebeta.dev is always redirected to othersite.com by resolving the name to the right IP.

My /etc/hosts file looks like this:
127.0.0.1 localhost 10.20.7.67 testsitealpha.dev othersite.dev testsitebeta.dev
The first two work. The last one doesn't. Why not? How do I make it work? The reason I am doing this, is because I have a test server (othersite.com), which is on the local network, but it's ip can vary. e.g. 10.20.7.98 one day, 10.20.7.35 another, etc.
So, how do I make my system always resolve testsitebeta.dev to the same ip as othersite.dev?

Benubird almost 11 yearsNot the kind of answer I'm looking for. This is for development; I don't want to modify any other machines, since the domain name (testsitebeta.dev) does not need to be accessible from anywhere but my local. I just want a way to tell my computer "treat name X like it was Y".

Jay Chakra about 7 years@Benubird: I am also looking for the same solution. But couldn't get it. Can you explain a little further how you setup?
