[SOLVED] Virtual host on httpd redirect unintentionally

February 08, 2024 apache, httpd.conf

Issue

My goal

Running 2 name virtual host with 1 IP. For example, front1.httpd.example.com and front2.httpd.example.com are accesible on 1 server's 1 httpd (parent) process(I want to listen on port 80 in both front1 and front2).

Environment

httpd 2.4 and Ubuntu 11(32bit)

What I did

I added to two virtual host on httpd.conf according to the latest offical document Name-based Virtual Host Support.

And also I update my server /etc/hosts and client hosts like the following.

server's hosts(220.xxx.xxx.xxx is some actual IP)

127.0.0.1 front1.httpd.example.com front2.httpd.example.com localhost

220.xxx.xxx.xxx front1.httpd.example.com
222.xxx.xxx.xxx front2.httpd.example.com

client's hosts

220.xxx.xxx.xxx front1.httpd.example.com
220.xxx.xxx.xxx front2.httpd.example.com

In addition, my hostname is front1.httpd.example.com

(Note: I also tried to add NameVirtualHost *:80 before the VirtualHost sections, but it just returns additional message "NameVirtualHost has no effect...")

Results

When I access to front1.httpd.example.com/index.html, htdocs/xxxx/index.html is returned. This is what I expected, but when I access to front2.httpd.example.com/index.html, also htdocs/xxxx/index.html is returned in spite of I intend to show htdocs/yyyy/index.html. (in browser console message, front2.httpd.example.com/index.html is found and then 302 redirect to front1.httpd.example.com/index.html)

Virtual host will return the first Virtual host value if there is no matching result to access. So, I also tried to change the oreder of the virtual host like the following:

First try:

<VirtualHost *:80>
    DocumentRoot "/opt/APACHE/httpd/htdocs/xxxx"
    ServerName front1.httpd.example.com
    ServerAlias front1.httpd.example.com
    ErrorLog "logs/dummy-host1.example.com-error_log"

    <Directory "/opt/APACHE/httpd/htdocs/xxxx">
      Options Indexes FollowSymLinks
      AllowOverride all
      Require all granted
    </Directory>
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/opt/APACHE/httpd/htdocs/yyyy"
    ServerName front2.httpd.example.com
    ServerAlias front2.httpd.example.com
    ErrorLog "logs/dummy-host2.example.com-error_log"
    <Directory "/opt/APACHE/httpd/htdocs/yyyy">
      Options Indexes FollowSymLinks
      AllowOverride all
      Require all granted
    </Directory>
</VirtualHost>

and second try:

<VirtualHost *:80>
    DocumentRoot "/opt/APACHE/httpd/htdocs/yyyy"
    ServerName front2.httpd.example.com
    ServerAlias front2.httpd.example.com
    ErrorLog "logs/dummy-host2.example.com-error_log"
    <Directory "/opt/APACHE/httpd/htdocs/yyyy">
      Options Indexes FollowSymLinks
      AllowOverride all
      Require all granted
    </Directory>
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/opt/APACHE/httpd/htdocs/xxxx"
    ServerName front1.httpd.example.com
    ServerAlias front1.httpd.example.com
    ErrorLog "logs/dummy-host1.example.com-error_log"

    <Directory "/opt/APACHE/httpd/htdocs/xxxx">
      Options Indexes FollowSymLinks
      AllowOverride all
      Require all granted
    </Directory>
</VirtualHost>

As a result, front2.httpd.example.com/index.html returns htdocs/yyyy/index.html, but front1.httpd.example.com/index.html also returns htdocs/yyyy/index.html. Therefore, I guess accessing request does not much any virtual host.

Refs and comments

I checked similar questions like this Virtual Host on CentOS5, but in my case I wrote hosts file on the both server and client, so DNS things are not for me, I think.

I had setup the httpd server for past a few years and also used VirtualHost with old stuff NameVirtualHost, but this time something I screwed up or I don't know. Please provide me any ideas?

My httpd.conf

ServerRoot "/opt/APACHE/httpd"

Listen 80

<VirtualHost *:80>
    DocumentRoot "/opt/APACHE/httpd/htdocs/xxxx"
    ServerName front1.httpd.example.com
    ServerAlias front1.httpd.example.com
    ErrorLog "logs/dummy-host1.example.com-error_log"

    <Directory "/opt/APACHE/httpd/htdocs/xxxx">
      Options Indexes FollowSymLinks
      AllowOverride all
      Require all granted
    </Directory>
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/opt/APACHE/httpd/htdocs/yyyy"
    ServerName front2.httpd.example.com
    ServerAlias front2.httpd.example.com
    ErrorLog "logs/dummy-host2.example.com-error_log"
    <Directory "/opt/APACHE/httpd/htdocs/yyyy">
      Options Indexes FollowSymLinks
      AllowOverride all
      Require all granted
    </Directory>
</VirtualHost>

Solution

I'm using OpenAM Web policy agent at this server instance.

As a result, just adding each FQDN to the FQDN virtual mapping on OpenAm agent profile reach the my goal.
