one dedicated server(centos/apache) hosts multi virtual servers, but all are led to first domain

kaisatec · July 28, 2013, 7:37am

I hope to host multi virtual servers on one dedicated server.
their domain are a.com b.com c.com which use same ip.

DocumentRoot at
/home/a/public_html
/home/b/public_html
/home/c/public_html

ftp root
/home/a/
/home/b/
/home/c/

below are what I did

in virtualmin, create virtual server named a.com b.com c.com
edit httpd.conf

vi /etc/httpd/conf/httpd.conf

< virtualHost *:80 >

DocumentRoot /home/a/public_html/

ServerName  *.a.com

ServerAlias *.a.com

ServerAlias a.com

< /VirtualHost >

< virtualHost *:80 >

DocumentRoot /home/b/public_html/

ServerName *.b.com

ServerAlias *.b.com

ServerAlias b.com

< /VirtualHost >

< virtualHost *:80 >

DocumentRoot /home/c/public_html/

ServerName *.c.com

ServerAlias *.c.com

ServerAlias c.com

< /VirtualHost >

3.restart apache, it display

[warn] default VirtualHost overlap on port 80, the first has precedence

but when I input a.com b.com c.com in web browser,

all are led to a.com rather than a.com b.com c.com

Your comment welcome

Try using the IP address instead of “*” in the VirtualHost directives. Apache has some quite complex rules when determining which virtual host to serve, and it’s best to be as specific as possible in VirtualHost. That’s what Virtualmin does too by default, and correctly; how come you had to edit http.conf at all?

kaisatec · July 28, 2013, 1:00pm

[warn] VirtualHost 50.23.16.18:80 overlaps with VirtualHost 50.23.16.18:80, the first has precedence, perhaps you need a NameVirtualHost directive

I do not what does this mean

kaisatec · July 28, 2013, 1:02pm

I checked http.conf

DocumentRoot is /var/html

and not virtual host site info

kaisatec · July 28, 2013, 1:25pm

I created the virtual servers in VirtualMin.

and check the http.conf

it did not change the DocumentRoot and add the virtual host info, so I added.

just wonder

if
name-based virtual host
http://httpd.apache.org/docs/2.4/vhosts/name-based.html

and virtual server are same thing?

Locutus · July 28, 2013, 2:14pm

Virtualmin doesn’t put the new servers into the main httpd.conf file, but in the sites-available subfolder.

kaisatec · July 28, 2013, 2:48pm

[root@server1 home]# cd /etc/apache2/sites-available/
-bash: cd: /etc/apache2/sites-available/: No such file or directory

kaisatec · July 28, 2013, 2:52pm

even I changed

virtualHost *:80
to
virtualHost 1.2.3.4:80 (1.2.3.4 is actual ip)

very thing is same.

All access for a.com b.com c.com are led to a.com

Locutus · July 28, 2013, 7:41pm

You should try recreating the virtual servers, and not mess with the httpd config. Virtualmin normally does this all okay, and if it doesn’t for you, there’s something else wrong.

If you delete and re-create the servers, and don’t edit the config, what’s the exact problem?

Eric · July 29, 2013, 2:36am

Hi Locutus!

Note that on CentOS, it actually does add the entries to the httpd.conf file.

Virtualmin tries to “go with the flow” regarding how a given distribution works… both Debian and Ubuntu use the /etc/apache2/sites-available/ dirs, with individual .conf files.

On CentOS, each individual VirtualHost entry is added to the end of the httpd.conf file, as CentOS doesn’t use the sites-available directory (even though I kind of which it would!)

kaisatec · July 29, 2013, 6:01am

then I created 2 virtual servers.

a.com b.com

I checked /home/

there are 2 directory ‘a’,‘b’

when use ftp connect, it will lead to /home/a and /home/b
I uploaded file to /home/a/public_html and /home/b/public_html via ftp.

but in /etc/httpd/conf/httpd.conf it wrote

DocumentRoot “/var/www/html”

Options FollowSymLinks AllowOverride None

when I input a.com b.com to web browser and go

it only displayed

Index of /

[ICO] Name Last modified Size Description

it looks like I am led to /var/www/html rather than /home/a/public_html and /home/b/public_html

Uh-oh. Trying to “reinstall Virtualmin” by running the installer script again is… problematic. Not recommended for sure. The installer script is meant primarily to be used on a fresh OS.

So at this point, I guess it’d be better to reinstall the OS and try again. Of course, Eric might have some further input on this, CentOS indeed isn’t my area of expertise. (Yes, I keep forgetting there are distros besides Debian/Ubuntu, which do things differently, like the httpd.conf bit. )

kaisatec · July 29, 2013, 10:45am

I think the problem is

I used ensim before, when I added a new site, there was option for ‘add ip-based site’ or and ‘add named-base site’.

But in virtualmin , there is no such option.

how to make the created new vitual server for name-based?

Locutus · July 29, 2013, 11:06am

Virtualmin uses name-based virtual hosts by default, when you have your server’s IP address configured as “shared IP”, which Virtualmin also does automatically by default.

Normally, you don’t have to do anything besides create the server, and Virtualmin takes care of creating a proper VirtualHost block.

Did you install Virtualmin on a fresh system, or over existing things?

kaisatec · July 29, 2013, 12:59pm

it is not a pure os
I have installed something
I do not hope to re-install os

I will check if the problem can be fixed

Eric · July 29, 2013, 1:21pm

Howdy,

If Apache isn’t configured to perform Name-based virtual hosting for your IP address, you may need to set that up.

That would normally be configured for you by default, when running the installer on a fresh system, but it’s possible that didn’t work properly in your case since it wasn’t a fresh system.

To do that, you’d just need to add a line like this to your httpd.conf:

NameVirtualHost x.x.x.x:80

Where “x.x.x.x” is your server’s IP address.

Also, note that there are some troubleshooting steps for the issue you’re seeing here in the section “the wrong website shows up”:

https://www.virtualmin.com/documentation/web/troubleshooting

kaisatec · July 30, 2013, 11:22am

I just purchased a vps server on linode with fresh os.
I will checked if the problem still existes
