+You may also want to check and see that mysqld is started on boot time.
+
+   /sbin/chkconfig --list mysqld

+
+This is good output:
+mysqld         0:off  1:off  2:off  3:on   4:on   5:on   6:off

+To diagnose, try logging in from the command line with

+and use the lonSqlAccess password
+listed in loncapa.conf (PerlSetVar lonSqlAccess ....).
+If this does not work, you may need to REMOVE the www\@localhost MySQL user.
+mysql -u root -p mysql
+mysql> delete from user where user='www'
+And then, you will need to repeat the MySQL configuration steps described at:
+       http://install.lon-capa.org/.
+
+**** NOTE **** ANOTHER possibility is that you are not running
+a compatible set of DBI, Mysql perl modules and MySQL server software.
