 </P>  You will need to check all the following things to ensure proper
 <P>  installation of your LON-CAPA system.
 This is the current list of steps to support LON-CAPA installation.  These steps have  <ul>
 been tested.  <li><a href="#wwwuser">

   <tr><td>
   <font size="+1">1</font>
   </td><td>
   <p>Is your system using shadow passwords? (Note: LON-CAPA will
   work with either MD5/non-MD5 configured systems).  If your
   system is not using shadow passwords, then do not perform
   any of the additional steps.  If your system is using shadow
   passwords, then you will need to perform the additional steps below.
   </p>
   <p>
   <strong>How to detect:</strong>
   <br />command: <tt>cat /etc/passwd | grep ':x:'</tt>
   </p>
   <p>If there is output such as "<tt>root:x:0:0:root:/root:/bin/bash</tt>",
   then your system is using shadow passwords and you will need to continue with
   the steps below.

   <h3>Installing LON-CAPA files</h3>
   <p>
   Download the most current
   <a href="http://install.lon-capa.org/versions/current/loncapa.tar.gz">
   loncapa.tar.gz</a>.
   </p>
   <p>
   The <strong>UPDATE</strong> command will refresh your filesystem with all
   the latest LON-CAPA software.
   </p>
   <table bgcolor="#aaaaaa" border="1">
   <tr><td><tt>./UPDATE</tt></td></tr>
   </table>
   <a name="checkrpms" />
   <h3>Checking your Linux RPMs</h3>
   <p>
   The <strong>CHECKRPMS</strong> command will check the RPMs on your machine
   against an FTP repository.
   </p>
   <table bgcolor="#aaaaaa" border="1">
   <tr><td><tt>./CHECKRPMS</tt></td></tr>
   </table>
   <a name="mysql" />
   <h3>Configuring the MySQL database</h3>
   <p>
   The following commands describe how to configure the MySQL database
   on your LON-CAPA server.
   </p>
   <table bgcolor="#aaaaaa" border="1"><tr><td>
   <pre>
   Enter the mysql shell---
   mysql -u root -p mysql
   
   Run these commands---
   CREATE DATABASE loncapa;
   
   INSERT INTO user (Host, User, Password)
   VALUES ('localhost','www',password('SOMEPASSWORD'));
   
   GRANT ALL PRIVILEGES ON *.* TO www@localhost;
   
   FLUSH PRIVILEGES;
   
   shell> mysql -u root mysql
   mysql> SET PASSWORD FOR root@localhost=PASSWORD('new_password');
   </pre>
   </td></tr></table>
   <a name="testing" />
   <h3>Testing to see if the LON-CAPA server is operational</h3>
   <p>
   The <strong>TEST</strong> command will check the installation software,
   the perl libraries on your system, the MySQL database, and
   will also automatically test the real-time operation of the 
   LON-CAPA Apache web server.
   </p>
   <table bgcolor="#aaaaaa" border="1">
   <tr><td><tt>./TEST</tt></td></tr>
   </table>
   <p>
   Using the <strong>TEST</strong> command will likely
   be an iterative process.
   It is normal to expect that the <strong>TEST</strong> command
   will recommend you perform various steps to ensure optimal
   performance of your LON-CAPA server.
