<H3>Current Reconfiguration Procedure</H3> |
|
<P> |
|
Currently, reconfiguration must be handled manually and involves an administrator |
|
altering configuration files present throughout the system. For a list of these |
|
files and their descriptions, visit <A HREF="http://install.lon-capa.org/3.1/loncapafiles/loncapafiles.html"> |
|
http://install.lon-capa.org/3.1/loncapafiles/loncapafiles.html</A>. |
|
</P> |
|
<H3>Future Reconfiguration Procedure (not yet implemented)</H3> |
|
<P> |
|
In the future, LON-CAPA Reconfiguration will be handled by a GUI tool (and text-based UI) |
|
developed as an offshoot from the RedHat anaconda python-Tk system. This tool is |
|
already working in many respects, but awaits completion. |

<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>Configuration files and examples</h3> |
|
<p> |
|
LON-CAPA currently depends on the following list of configuration |
|
files. Locations of these files are by default. Depending on your |
|
Linux distribution (RedHat, Mandrake, Debian, etc.), the file paths |
|
may be elsewhere. |
|

<h3>Current Reconfiguration Procedure</h3> |
|
<p> |
|
We recommend that you handle the reconfiguration manually. |
|
A knowledgeable system administrator should alter these configuration |
|
files. |
