+NOTE: +If you want to simultaneously install both RedHat 7.3 and LON-CAPA +(to ensure 100% reliability), follow these +alternative directions. +


 

Creating a user 'www'

Unpack the mod_auth_external source by +running the following command

+tar xzvf mod_auth_external-2.1.13.tar.gz

+ +4 + +

Go to the pwauth directory by +running the following command +

+

+ + +5 + +

Edit config.h and change SERVER_UIDS definition +

+

+Change the line +

#define SERVER_UIDS 513 /* user "www" */ +
where in this example 513 corresponds to the user id of 'www'. +

Compile the pwauth executable by +running the following command +

Install pwauth by doing the following +

Fixing /etc/hosts

+

+A common RedHat glitch of new installations (RedHat's fault, not LON-CAPA) +is the generation of /etc/hosts. +

+

+It should look something like this (except the myschool line +should be replaced with settings specific to your machine): +

+ + +
+
+127.0.0.1		localhost.localdomain localhost
+12.34.56.78		www.myschool.edu myschool
+

Configuring the MySQL database

The following commands describe how to configure the MySQL database on your LON-CAPA server. +
Note: +

+ +

+The following instructions assume you are logged in as 'root'.

-
+

Entering the mysql shell

+
-Enter the mysql shell---
 mysql -u root -p mysql
+OR
+mysql -u root mysql (depending on whether you have set a root password)
+
+
+

Creating the mysql 'www' user (after entering mysql shell)

+
+
+mysql> CREATE DATABASE loncapa;
 
-Run these commands---
-CREATE DATABASE loncapa;
-
-INSERT INTO user (Host, User, Password)
-VALUES ('localhost','www',password('SOMEPASSWORD'));
-
-GRANT ALL PRIVILEGES ON *.* TO www@localhost;
+mysql> INSERT INTO user (Host, User, Password)
+mysql> VALUES ('localhost','www',password('localhostkey'));
 
-FLUSH PRIVILEGES;
+mysql> INSERT INTO db VALUES ('localhost','loncapa','www',
+mysql> 'Y','Y','Y','Y','Y','Y','N','Y','Y','Y');
 
+mysql> FLUSH PRIVILEGES;
+
+
+

SECURITY: set a password for the mysql 'root' user

+
+
 shell> mysql -u root mysql
-mysql> SET PASSWORD FOR root@localhost=PASSWORD('new_password');
+mysql> SET PASSWORD FOR root@localhost=PASSWORD('ROOTPASSWORD');

LON-CAPA Installation

Current Installation Procedure

+

SECURITY: only allow access from localhost

+
+
+shell> mysql -u root -p mysql
+mysql> DELETE FROM user WHERE host<>'localhost';
+
+

Testing to see if the LON-CAPA server is operational

-Scott Harrison +The TEST 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.

-You can also try to install LON-CAPA on an existing installation of -RedHat 6.2. Please see -how_to_install_loncapa_on_a_preinstalled_system.txt. +Using the TEST command will likely +be an iterative process. +It is normal to expect that the TEST command +will recommend you perform various steps to ensure optimal +performance of your LON-CAPA server.
