<p>$Date$; $Revision$</p> |
There are about a dozen files on the LON-CAPA server systems |
|
which customize how each system interacts with the rest of the |
|
LON-CAPA network. |
|
</p> |
|
<p> |
|
The two most important configuration files are: |
|
</p> |
|
<ul> |
|
<li><strong>loncapa.conf</strong> - |
|
typically located in the directory <tt>/etc/httpd/conf/</tt> |
|
<br /><i>contains variables and modifications necessary for |
|
the effective running of the Apache web server</i> |
|
<br /> |
|
</li> |
|
<li><strong>hosts.tab</strong> - |
|
typically located in the directory <tt>/home/httpd/lonTabs/</tt> |
|
<br /><i>is a listing of all other internet machines that a server |
|
system considers to be valid server systems on the LON-CAPA |
|
network</i> |
|
<br /> |
|
</li> |
|
</ul> |

<h3>Alternative Reconfiguration Procedure (alpha software)</h3> |
|
<p> |
|
LON-CAPA Reconfiguration can also be handled by a GUI tool (and text-based UI) |
|
developed as an offshoot from the RedHat anaconda python-Tk system. This tool |
|
should be present on your LON-CAPA system at |
|
/usr/sbin/loncapaconfig. |
