2: There are about a dozen files on the LON-CAPA server systems
3: which the system administrator may need to adjust.
4: </p>
5: <p>
6: The two most important configuration files are:
7: </p>
8: <ul>
9: <li><strong>loncapa.conf</strong> -
10: typically located in the directory <tt>/etc/httpd/conf/</tt>;
11: <br /><i>contains machine-specific and institution-specific
12: variables and modifications necessary for
13: the effective running of the Apache web server;
14: note that there is also a <strong>loncapa_apache.conf</strong>
15: which should be installed, but not modified</i>
16: <br />
17: </li>
18: <li><strong>hosts.tab</strong> -
19: typically located in the directory <tt>/home/httpd/lonTabs/</tt>;
20: <br /><i>is a listing of all other internet machines that a server
21: system considers to be valid server systems on the LON-CAPA
22: network</i>
23: <br />

25: </ul>

28: <h3>Current Reconfiguration Procedure</h3>
29: <p>
30: After making any configuration change, you will need to restart system
31: services. The two most important system services on a LON-CAPA system are
32: <strong>loncapa</strong> and <strong>httpd</strong>. Here are the
33: commands for restarting the system services:
34: </p>
35: <table bgcolor="#aaaaaa" border="1"><tr><td>
36: <tt>/etc/rc.d/init.d/loncapa restart</tt>
37: <br /><tt>/etc/rc.d/init.d/httpd restart</tt>
38: </td></tr></table>
39: <p>
40: We recommend that a knowledgeable system administrator should
41: perform any adjustments on a LON-CAPA server machine.
42: Locations of these files are by default. Depending on your
43: Linux distribution--RedHat, Mandrake, Debian, etc, the file paths
44: may be elsewhere.
45: </p>
46: <h3>Configuration files that will have to be altered</h3>
47: <p>
48: LON-CAPA currently depends on the following list of configuration
49: files. Note that <tt>loncapa.conf</tt> is automatically
50: altered by the installation/upgrade scripts associated with
51: the tarball-distribution (see the <b>INSTALL</b> and <b>UPGRADE</b>
52: sections of this web-site). (Thus, the system administrator should
53: not have to further adjust <tt>loncapa.conf</tt> from the terminal.)

72: <h3>Configuration files that do not have to be altered</h3>
73: <p>
74: The following configuration files are critical for the correct
75: performance of a LON-CAPA server machine. Typically, these configuration
76: files do not need to be adjusted by the system administrator.
77: </p>
78: <ul>
79: <li><a href="confexamples/loncapa_apache.conf">[EXAMPLE]</a>
80: /etc/httpd/conf/loncapa_apache.conf</li>

85: <h3>Configuring Secondary Services</h3>
86: <p>
87: LON-CAPA does not provide integrated support for secondary services.
88: The expectation is that knowledgeable system administrators will
89: customize these secondary services for their institution.
90: </p>
91: <p>
92: We do, however, provide example configurations of services that you
93: may want to deliver with LON-CAPA (i.e. Samba and AppleChooser).
