Apache Redirect To Another Server with subdomain

Question

I am currently running CentOS which hosts my web and gitlab server and a windows machine that is hosting a subsonic server. Currently, my ip points to the CentOS but does not redirect correctly. I am able to access / but unable to access any other sites with the subdomain despite the settings I have made so I would like to know where I am going wrong and how to rectify the issue. Is it also possible that when people enter http://git.example.com that it will automatically be redirected to https://git.example.com? Thanks in advance!

NameVirtualHost *:80

Solution

You have a mismatch between

NameVirtualHost *:80

and

<VirtualHost *>

You need to change the VirtualHost to be the same as NameVirtualHost, i.e.

<VirtualHost *:80>

As for the redirect, vic's answer should help - if not, have a look at Redirect, Change URLs or Redirect HTTP to HTTPS in Apache - Everything You Ever Wanted to Know About Mod_Rewrite Rules but Were Afraid to Ask

Sry my vote score is low so formatting is not allowed for me yet.

shouldn't i be using proxy instead of mod_rewrite? when should i be using proxy instead?

[Hong Yi]

i am a bit confused with this. what redirect and proxy should be done? shouldn't the virtualhost:80 be listening for the subdomain already? then proxy to access the actual content?

You asked how to redirect http://git.example.com to https://git.example.com. You do this by having a virtualhost *:80 with ServerName git.example.com and within that virtualhost you use mod_rewrite to redirect to https://git.example.com.

[Hong Yi]

how about the proxy of music.comapny.com to the other server? I can't seem to get it working. :/

"Can't seem to get it working" is insufficient data. What do your logs say? Please add that information to the question.
