  1. Get LON-CAPA on a CD by - -
  2. Install with CD-ROM - -
  3. After installation, restart the computer. Login as root. Enter this command (you only need to do this after your first reboot): -

-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. +You will need to check all the following things to ensure proper +installation of your LON-CAPA system.

- - + +

+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'

+

+Execute the following command to create a user named 'www' on your +LON-CAPA server: +

+
+/usr/sbin/useradd www +
+
+

Make a LON-CAPA system work with shadow passwords

+ + + + + + + + + +
Step #Description
+1 + +

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. +

+

+How to detect: +
command: cat /etc/passwd | grep ':x:' +

+

If there is output such as "root:x:0:0:root:/root:/bin/bash", +then your system is using shadow passwords and you will need to continue with +the steps below. +

+
+2 + +

Retrieve the mod_auth_external source by +running the following command +

+

+wget http://www.wwnet.net/~janc/software/mod_auth_external-2.1.13.tar.gz + +

+
+3 + +

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 +

+

+cd mod_auth_external-2.1.13/pwauth/ +

+
+5 + +

Edit config.h and change SERVER_UIDS definition +

+

+Determine the user id of 'www': +
grep ^www /etc/passwd | cut -d':' -f3 +
+Change the line +
#define SERVER_UIDS 99 /* user "nobody" */ +
to be +
#define SERVER_UIDS 513 /* user "www" */ +
where in this example 513 corresponds to the user id of 'www'. +

+
+6 + +

Compile the pwauth executable by +running the following command +

+

+make +

+
+7 + +

Install pwauth by doing the following +

+

+cp pwauth /usr/local/sbin/ +
chmod 6755 /usr/local/sbin/pwauth +

+

+Edit (creating the file) /etc/pam.d/pwauth to have the contents: +

+
+        auth       required     /lib/security/pam_pwdb.so shadow nullok
+        auth       required     /lib/security/pam_nologin.so
+        account    required     /lib/security/pam_pwdb.so
+
+
+
+

Installing LON-CAPA files

+

+Download the most current + +loncapa-current.tar.gz. +

+ + +
wget http://install.lon-capa.org/versions/loncapa-current.tar.gz + +
+tar xzvf loncapa-current.tar.gz +
+cd loncapa-N.N (N.N is the version number)
+

+The UPDATE command will refresh your filesystem with all +the latest LON-CAPA software. +

+ + +
./UPDATE
+ +

Checking your Linux RPMs

+

+The CHECKRPMS command will check the RPMs on your machine +against an FTP repository. +

+ + +
./CHECKRPMS
+
+

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

+
+
+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;
+
+mysql> INSERT INTO user (Host, User, Password)
+mysql> VALUES ('localhost','www',password('localhostkey'));
+
+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('ROOTPASSWORD');
+
+
+

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

+

+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. +

+ + +
./TEST
+

+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. +
