 Posted: Thu 12 Nov '09 9:31 Post subject: Two webservers (public and Internal) : A suggestion please |
 |
|
Hello. I'm having 2 webservers in the following configuration, behind a firewall:
The webserver 1 is made public. The webserver 2 is only for internall use.
I want to redirect a page (or a link) from the webserver 1 to one php script from webserver 2, but the script must be runned on webserver 2 because it has all the requirements (programs) needed to run the script.
Also, if it's possible and if I'm not asking too much I want to be runned internally (using 192.168.1.3).
I don't know If I explained good, but if someone can help me, please do

| You could use the Webserver1 as a reverse proxy. than the script still can run on the second server. |

Hello again.
I installed a dummy server to test the configuration.
I removed the comment from
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
and
Include conf/extra/httpd-vhosts.conf
from httpd.conf
In httpd-vhosts.conf I have the following:
<VirtualHost *:80>
ServerAdmin webmaster@domain.com
DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs"
ServerName www.domain.com
ServerAlias www.domain.com
ErrorLog "logs/domain.com.localhost-error.log"
CustomLog "logs/domain.com.localhost-access.log" common
</VirtualHost>
<VirtualHost *:80>
ServerName test.domain.com
ProxyRequests off
ProxyPass / http://192.168.1.3/somefile.php
ProxyPassReverse / http://192.168.1.3/somefile.php
</VirtualHost>
but it seems that it does not work 
Main page works but not the reverse proxy
#edit:
I changed
<VirtualHost *:80>
ServerName test.domain.com
ProxyRequests off
ProxyPass / http://192.168.1.3/somefile.php
ProxyPassReverse / http://192.168.1.3/somefile.php
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
</VirtualHost>
and it worked. I do not know how, but it worked. Now it's not working...
#edit2: Now it's working. The problem was the DNS. |

The final configuration is:
<VirtualHost *:80>
ServerAdmin webmaster@domain.com
DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs"
ServerName domain.com
ServerAlias domain.com
ErrorLog "logs/domain.com.localhost-error.log"
CustomLog "logs/domain.com.localhost-access.log" common
</VirtualHost>
<VirtualHost *:80>
ServerName test.domain.com
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPreserveHost On
ProxyRequests off
ProxyPass / http://192.168.1.3/
ProxyPassReverse / http://192.168.1.3/
</VirtualHost>
I want to ask something else.
When I acces the server it appear something like:
test.domain.com/SomeDirectory/somefile.php
It is possible to hide "SomeDirectory/somefile.php" from the url in address bar and the address bar to look like test.domain.com???
The page redirected is only one page(one script), it does not have links to other pages... |

Yes you can
-snip-
| Code: |
..
ProxyPass / http://192.168.1.3/SomeDirectory/
ProxyPassReverse / http://192.168.1.3/SomeDirectory/
..
|
Than you can rename that file to index.php or change the directory index on the second server to DirectoryIndex somefile.php index.php index.htm index.html |

Works perfectly, and thank you again...
Now, maybe I should make other topic but since is almost the same, I'll write here.
Because all other applications are in form domain.com/application, I want to ask how to make something like:
domain.com/test
I have read This topic: http://www.apachelounge.com/viewtopic.php?t=1569
Can I use it (mod_proxy_html) ?
I must tell that there are other applications running on the 192.168.1.2 server in form of domain.com/app
If so, Where I put that script? |

Well if the folder is on the same server you could use an alias.
example
| Code: |
Alias /test "c:/path/to/application"
<Directory "c:/path/to/application">
Order allow,deny
Allow from all
</Directory>
|
You need mod_proxy_html only when you have to correct paths in the html from the remote server in reverse proxy situation. |

No, it's not, I want to use it in the same way that I described earlier.
But instead of subdomain.domain.com, to use domain.com/subdomain
(because for now, all applications are of this form, but on the same server-except for this one) Can it be done?
I think that this could help me:
| Code: | ProxyPass /app1/ http://internal1.example.com/
ProxyPass /app2/ http://internal2.example.com/
ProxyHTMLURLMap http://internal1.example.com /app1
ProxyHTMLURLMap http://internal2.example.com /app2 |
(from the link that I show earlier)
But where do I put that code? In httpd-vhosts.conf or httpd.conf ? |

Put it where ever you like to put it. Don't forget to use the location stuff there, too.
Some example
| Code: |
ProxyPass /home http://192.168.178.21/home
ProxyPassReverse /home http://192.168.178.21/home
ProxyHTMLURLMap http://192.168.178.21/home /home
<Location /home>
ProxyPassReverse /home
SetOutputFilter proxy-html
ProxyHTMLURLMap /home /
RequestHeader unset Accept-Encoding
</Location>
|
You can read the whole stuff about it at the authors page from mod_proxy_html http://www.apachetutor.org/admin/reverseproxies |

Unfortunately, it does not work
I will come back to tell more.
| Code: | ProxyRequests off
ProxyPass /text/ http://192.168.1.3/sosiri_txt
ProxyPass /grafic/ http://192.168.1.3/sosiri_graf
ProxyHTMLURLMap http://192.168.1.3/sosiri_txt /text
ProxyHTMLURLMap http://192.168.1.3/sosiri_graf /grafic
<Location /text/>
ProxyPassReverse /
ProxyHTMLEnable On
ProxyHTMLURLMap / /text/
RequestHeader unset Accept-Encoding
</Location>
<Location /grafic/>
ProxyPassReverse /
ProxyHTMLEnable On
ProxyHTMLURLMap / /grafic/
RequestHeader unset Accept-Encoding
</Location> |

In my example it was different
you have
| Code: |
proxyHTMLURLMap / /text/
and
ProxyHTMLURLMap / /grafic/
|
but it should be
| Code: |
proxyHTMLURLMap /text/ /
and
ProxyHTMLURLMap /grafic/ /
|

I tryed your suggestion, this was after that.
It seems that the apache server is no longer starting after I inserted that.
Even if I modify with the last configuration (the one discussed and worked) I must restart the PC in order to be able to start the apache webserver.
I disabled virtualhosts, I put this in httpd.conf. Same thing
Maybe is because that I don't have
| Code: | LoadFile /usr/lib/libxml2.so
...
LoadModule xml2enc_module modules/mod_xml2enc.so |
??? |

If you are using mod_proxy_html then I guess it would need libxml2.DLL looking at my build note for the beast.
If you drop that dll in your Apache's bin/ folder there is no need for the LoadFile line. It looks like the mod_proxy_html here in the downloads includes the mod_xml2enc.so and libxml2.dll .. and a config sample. |

When I tryed to start the server, the error was: The requested operation has failed.
After I changed back, again, I had to reboot the pc to make apache to start.
I have 1 web server, 1 forum both with "/" ending
(domain.com/app)
Any help is appreciated  |

I'm not an expert in reverse proxy, but AFAIK your block should look like
| Code: |
ProxyRequests off
ProxyPass /text/ http://192.168.1.3/sosiri_txt/
ProxyPass /grafic/ http://192.168.1.3/sosiri_graf/
<Location /text/>
ProxyPassReverse /
ProxyHTMLEnable On
ProxyHTMLURLMap / /text/
RequestHeader unset Accept-Encoding
</Location>
<Location /grafic/>
ProxyPassReverse /
ProxyHTMLEnable On
ProxyHTMLURLMap / /grafic/
RequestHeader unset Accept-Encoding
</Location>
|
hm, another way might be to have a windows share and the data with an alias over a UNC Drive. See http://www.apachelounge.com/viewtopic.php?t=3259 |
