<h2><a name="_Toc421867172">Configuring the Apache Web Server</a></h2>

<p>The configuring of the Apache Web Server and the input of LON-CAPA
configuration values is handled automatically by the <tt><span
style='font-family:"Courier New"'>./UPDATE</span></tt> command. In this
document, the details of what the <tt><span style='font-family:"Courier New"'>./UPDATE</span></tt>
command facilitates are described. </p>

<p><tt><span style='font-family:"Courier New"'>/etc/httpd/conf/httpd.conf</span></tt>
is adjusted to include the LON-CAPA web server configuration. This happens by
appending the following line to <tt><span style='font-family:"Courier New"'>httpd.conf</span></tt>:
</p>

<table border=1 cellpadding=0 bgcolor="#aaaaaa" style='mso-cellspacing:1.5pt;
 background:#AAAAAA'>
 <tr>
  <td style='padding:.75pt .75pt .75pt .75pt'>
  <p class=MsoNormal><tt><span style='font-family:"Courier New"'>Include
  conf/loncapa_apache.conf</span></tt> </p>
  </td>
 </tr>
</table>

<p>The <tt><span style='font-family:"Courier New"'>/etc/httpd/conf/loncapa_apache.conf</span></tt>
file customizes the Apache Web Server to have the needed configuration to
deliver LON-CAPA on the world-wide web. The <tt><span style='font-family:"Courier New"'>loncapa_apache.conf</span></tt>
file does not contain any information specified by the system administrator.
The <tt><span style='font-family:"Courier New"'>loncapa_apache.conf</span></tt>
file does, however, cause <tt><span style='font-family:"Courier New"'>loncapa.conf</span></tt>
to be included. <tt><span style='font-family:"Courier New"'>/etc/httpd/conf/loncapa.conf</span></tt>
contains only information specified by the system administrator. Generally
speaking, the information inside <tt><span style='font-family:"Courier New"'>/etc/httpd/conf/loncapa.conf</span></tt>
is machine-specific (each LON-CAPA server has its own specific values inside <tt><span
style='font-family:"Courier New"'>loncapa.conf</span></tt>). </p>

<p><tt><span style='font-family:"Courier New"'>/etc/httpd/conf/loncapa_apache.conf</span></tt>

     &quot;loncapa.org&quot;, or Windows file server domains. If you are

<h2><a name="_Toc421867173">Configuring the LON-CAPA Network</a></h2>

<p>In order for LON-CAPA to connect to other servers that provide educational
resources or to balance the load of high-volume web-requests, there needs to be
a way to access information that describes the other LON-CAPA servers present
on the internet. </p>

<p><tt><span style='font-family:"Courier New"'>/home/httpd/lonTabs/hosts.tab</span></tt>
defines all of the other machines that a given LON-CAPA server can interact
with. (In a sense, this is a mechanism of security so that connections cannot
be attempted from spurious entities.) </p>

<p>The format of <tt><span style='font-family:"Courier New"'>hosts.tab</span></tt>
is to define each LON-CAPA server on separate lines. Each line is
field-separated by colons ':'.</p>

<p>An example entry in <tt><span style='font-family:"Courier New"'>hosts.tab</span></tt>
is: </p>

<table border=1 cellpadding=0 bgcolor="#aaaaaa" style='mso-cellspacing:1.5pt;
 background:#AAAAAA'>
 <tr>
  <td style='padding:.75pt .75pt .75pt .75pt'>
  <p class=MsoNormal><tt><span style='font-family:"Courier New"'>vulon1:msuvu:library:loncapa3.vu.msu.edu:35.9.80.250</span></tt>
  </p>
  </td>
 </tr>
</table>

<p>The first field is the LON Host ID (see the above description of <tt><span
style='font-family:"Courier New"'>loncapa.conf</span></tt>). The second field
is the Domain Name. The third field is the server type (see the section
&quot;Different Types of LON-CAPA Servers&quot;). The fourth field is a
DNS-registered full IP name. The fifth field is the numeric IP address. </p>

<p><tt><span style='font-family:"Courier New"'>/home/httpd/lonTabs/spare.tab</span></tt>
is a list of LON Host IDs corresponding to Access Servers (or Library Servers).
<tt><span style='font-family:"Courier New"'>spare.tab</span></tt> should not be
the same on every LON-CAPA server machine. The purpose of this list is to
specify other servers toward which user web requests can be re-directed.
Current experience is that the servers on <tt><span style='font-family:"Courier New"'>spare.tab</span></tt>
are particularly active (and much needed) shortly before homework assignments
are due.... </p>

<p>An example of <tt><span style='font-family:"Courier New"'>spare.tab</span></tt>
relates to the Library Server <strong>vulon1</strong> which load-balances the
requests onto two other Access Servers as shown in the example <tt><span
style='font-family:"Courier New"'>spare.tab</span></tt> below: </p>

<table border=1 cellpadding=0 bgcolor="#aaaaaa" style='mso-cellspacing:1.5pt;
