There are four major steps needed to install the Content Server: install the HTTP server, install the PLATO® Interactive Mathematics content, configure your ISS database to point to this content server, and configure and start the HTTP server.

Select your network parameters

Your HTTP server will have to be assigned a fixed IP address so that students will be able to reliably run content from the server. Please write the network parameters for this below

<Your IP Address> = _________________________

<Your Subnet Mask> = _______________________

<Your Default Gateway> = ____________________

Set the machine up to allow remote logon

Since your Linux machine is acting as a server, you will want to set it up for remote logon.

NOTE: If your server came without a monitor, in order for you to use it, you will have to boot it one time with a monitor and set up the server network settings and the security settings. When you boot the server, you should log on as:
Username: root
Password: ascsupport
Note that you will change this password after your content is loaded onto the server.

Type startx to get to the graphical screen (gnome mode).

1. Click the Red Hat at the bottom left hand side of the screen and choose System Settings. Then, choose Network. The Network Configuration dialog is displayed.

2. At the Network Configuration dialog, shown below, click the Edit button. The Ethernet Device dialog is displayed.

3. Because you are using this machine as an Internet service, it will need to have a fixed IP address. To implement the Internet service, it is recommended that you configure the machine with a static IP address.

In the Ethernet Device dialog box, shown below, select the Statically set IP addresses radio button and then fill in the Address, Subnet Mask, and Default Gateway Address fields, as shown below. Use the information you noted in Step 1 to fill in the requested information. When you are done, click OK.

4. Click the Red Hat at the bottom left hand side of the screen and choose System Settings. Then, choose Security Level. The Security Level Configuration dialog box, as shown below, is displayed.

6. Restart your machine and login.

7. Download putty.exe from http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe onto a Windows machine.

8. Double click putty.exe and enter the IP address of your server and select the SSH radio button, as shown below.

9. In the Putty dialog box, click Open.

10. Select yes when you are asked if you want to continue. A terminal window like the one shown below is displayed.

11. In the Putty terminal window, login as root/ascsupport.

NOTE: Once you complete these steps, you will be fully configured to run your Linux-based content server without a monitor. You can remove the monitor at this point.

Install Apache

Although your machine comes pre-configured with Apache, in order for it to work properly it will need to be reconfigured to use a specially compiled version of Apache. To re-configure Apache, follow the steps below.

1. Turn off the current version of Apache. To do this

· In the Putty terminal window, type vi /etc/rc.d/init.d/httpd

· In the httpd file, find the following lines:

apachectl=/usr/sbin/apachectl

httpd=/usr/sbin/httpd

prog=httpd

The text to the right of apachectl shows the location of the current apachectl – in this case it is located at /usr/sbin/apachectl.

· Exit the vi editor (:q)

· In the Putty terminal window, type the following command:

<path to apachectl> stop

where <path to apachectl> is the value found in the “apacehctl=…” line in the httpd file. For example, using the value in the sample above, you would type the following: /usr/sbin/apachectl stop.

2. Recompile apache by copying and pasting the following 11 commands into the Putty terminal window.

mkdir /usr/src/apache

cd /usr/src/apache

lwp-download http://archive.apache.org/dist/httpd/old/apache_1.3.27.tar.gz

lwp-download http://perl.apache.org/dist/mod_perl-1.27.tar.gz

tar xzvf apache_1.3.27.tar.gz

tar xzvf mod_perl-1.27.tar.gz

cd mod_perl-1.27

perl Makefile.PL APACHE_SRC=../apache_1.3.27/src DO_HTTPD=1 USE_APACI=1 EVERYTHING=1 APACI_ARGS=-enable-module=expires

make && make test && make install

cd ../apache_1.3.27

make install

3. In the Putty terminal window, type the following:

vi /etc/rc.d/init.d/httpd

4. In the httpd file, change the 3 configuration lines shown below

apachectl=/usr/sbin/apachectl

httpd=/usr/sbin/httpd

prog=httpd

apachectl=/usr/local/apache/bin/apachectl

httpd=/usr/local/apache/bin/httpd

prog=httpd

5. Save the file and exit the vi editor (:wq).

6. Copy and paste the following line into the Putty terminal window to start Apache.

/usr/local/apache/bin/apachectl start

Configure HTTP Server

Configure your HTTP server to work with the PLATO® Interactive Mathematics content.

1. In the Putty terminal window, type the following:

vi /usr/local/apache/conf/httpd.conf

2. Add the following line to the very bottom of the httpd.conf file:

include conf/asc_conf.conf

3. Save the file and exit the vi editor (:wq).

4. Copy and paste the following 8 lines into the Terminal window.

cd /usr/local/apache/conf

lwp-download http://patchmanager.academic.com/linux_content_installer/linux/content_server/conf/asc_conf_mod_expires.conf

mv asc_conf_mod_expires.conf.txt asc_conf.conf

mkdir /usr/local/apache/Apache

cd /usr/local/apache/Apache

lwp-download http://patchmanager.academic.com/linux_content_installer/linux/content_server/Apache/Lowercase.pm

/usr/local/apache/bin/apachectl stop

/usr/local/apache/bin/apachectl start

5. Test your server setup. To do this, enter the following command into the Putty terminal window:

lwp-request http://localhost/

This command should give you a listing of the http directory and not an “Internal Server Error” message.

Install the PLATO® Interactive Mathematics Content

Install the PLATO® Interactive Mathematics content by copying the contents of the PLATO® Interactive Mathematics lesson CDs to the server.

1. Create the directory into which you will copy the PLATO® Interactive Mathematics content. To do this, type the following command in the Putty terminal window:

mkdir /usr/local/apache/htdocs/interactive_math

2. Place the Prealgebra Part 2 CD into the CD-ROM drive on your content server. Then return to the workstation and type the following in the Putty terminal window:

mv -fv /mnt/cdrom/academic/* /usr/local/apache/htdocs/interactive_math

NOTE: you need to start with the Prealgebra Part 2 CD because it contains glossary files needed at the start of the copying process.

3. Repeat the above step for each PLATO® Interactive Mathematics content CD you wish to load onto your content server.

4. Once the contents of all of the CDs have been loaded, install the PLATO® Interactive Mathematics web content patch by copying and pasting the following commands into the Putty terminal window:

cd /usr/local/apache/htdocs

lwp-download http://patchmanager.academic.com/linux_content_installer/im_math_web_diff.tar.gz

tar zxvf im_math_web_diff.tar.gz

mv -fv im_math_web_diff/* interactive_math

Change Content File Ownership and Group

In order to make sure that all of the files can be delivered by the Linux-based server we want to verify that all of the files are owned by the default owner of the Apache process.

1. Change the file ownership and group to “nobody”. To do this, copy and past the following commands into the Putty terminal window:

lwp-download http://patchmanager.academic.com/linux_content_installer/linux.tar.gz

tar –zxvf linux.tar.gz

cd /usr/local/apache/htdocs/linux/content_server/set_permissions

./set_all_perms.pl

NOTE: the process started by these commands will take a while to complete.

2. Verify that the changes were successful by running the verification script. To do this, enter the following command in the Putty terminal window:

./check_all_perms.pl

The script should return nothing.

Configure Apache to Start Automatically

In order to ensure that Apache is running each time you restart your server Apache needs to be set up as a service. Use the steps below to do this.

1. In the Putty terminal window, type

lwp-download http://patchmanager.academic.com/linux_content_installer/asc /etc/rc.d/init.d

2. In the Putty terminal window type:
