63: <p>Is your system using shadow passwords? (Note: LON-CAPA will
64: work with either MD5/non-MD5 configured systems). If your
65: system is not using shadow passwords, then do not perform
66: any of the additional steps. If your system is using shadow
67: passwords, then you will need to perform the additional steps below.
68: </p>
69: <p>
70: <strong>How to detect:</strong>
71: <br />command: <tt>cat /etc/passwd | grep ':x:'</tt>
72: </p>
73: <p>If there is output such as "<tt>root:x:0:0:root:/root:/bin/bash</tt>",
74: then your system is using shadow passwords and you will need to continue with
75: the steps below.

186: <h3>Configuring the MySQL database</h3>
187: <p>
188: The following commands describe how to configure the MySQL database
189: on your LON-CAPA server.
190: <br />Note:
191: </p>
192: <ul>
193: <li>you should substitute 'ROOTPASSWORD' with something very hard to guess
194: (it does not have to be the Linux OS root password)
195: </li>
196: <li>The MySQL www@localhost user must always have a password of 'localhostkey'
197: in order for there to be correct operation of a standard LON-CAPA system.
198: </li>
199: </ul>
200: <p>
201: The following instructions assume you are logged in as 'root'.
202: </p>
203: <p>Entering the mysql shell</p>
204: <table bgcolor="#aaaaaa" border="1"><tr><td>
205: <pre>

239: <h3>Testing to see if the LON-CAPA server is operational</h3>
240: <p>
241: The <strong>TEST</strong> command will check the installation software,
242: the perl libraries on your system, the MySQL database, and
243: will also automatically test the real-time operation of the
244: LON-CAPA Apache web server.
245: </p>
246: <table bgcolor="#aaaaaa" border="1">
247: <tr><td><tt>./TEST</tt></td></tr>
248: </table>
249: <p>
250: Using the <strong>TEST</strong> command will likely
251: be an iterative process.
252: It is normal to expect that the <strong>TEST</strong> command
253: will recommend you perform various steps to ensure optimal
254: performance of your LON-CAPA server.
