Configuration of a LON-CAPA Server

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.

The two most important configuration files are:

loncapa.conf - typically located in the directory /etc/httpd/conf/
contains variables and modifications necessary for the effective running of the Apache web server
hosts.tab - typically located in the directory /home/httpd/lonTabs/
is a listing of all other internet machines that a server system considers to be valid server systems on the LON-CAPA network

Configuration files and examples

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.

[EXAMPLE] /etc/krb.conf
[EXAMPLE] /etc/httpd/conf/access.conf
[EXAMPLE] /etc/httpd/conf/loncapa.conf
[EXAMPLE] /home/httpd/lonTabs/hosts.tab
[EXAMPLE] /home/httpd/lonTabs/spare.tab
[EXAMPLE] /home/httpd/lonTabs/htpasswd
[EXAMPLE] /etc/smb.conf
[EXAMPLE] /etc/ntp.conf
[EXAMPLE] /home/httpd/html/res/adm/includes/un_keyword.tab
[EXAMPLE] /home/httpd/lonTabs/language.tab
[EXAMPLE] /etc/ntp/step-tickers
[EXAMPLE] /etc/pam.d/pwauth
[EXAMPLE] /etc/atalk/config

Current Reconfiguration Procedure

We recommend that you handle the reconfiguration manually. A knowledgeable system administrator should alter these configuration files.
