CSCI A348/548
Lecture Notes One

Fall 2000

Account creation information. Setting up Apache for Unix. Basic directory structure.

This will be a high bandwidth class. You will need to absorb a lot of information. You will need patience, and an ability to enjoy (or accept) the idea that things could be done in more than one way. We will try to match your enthusiasm.

Introduction and announcements:

Lectures meet in LH 102 (TR, 7pm)
Labs meet in LH 115. Access provided by the instructor.
Office hours will be kept in LH016 as posted or by appointment.
Newsgroup: ac.csci.a348
Instructor's coordinates:
E-mail: dgerman@indiana.edu
Telephone: 855-7071
Office: Lindley Hall 301G
Burrow accounts need to be created: use
http://accounts.ucs.indiana.edu
to create your own account if you don't have one. You will need to have an IUB Network ID. If you experience any difficulties please ask your instructor for help.
The burrow cluster is located in LH004. You can get individual access to the room if you go to LH215 with your student photo ID and request access. You will need to fill out a form and shortly after that you will be able to use your student ID to enter the room.
The machine on which we will be working is
```
burrowww.cs.indiana.edu
```
This machine has an alias
```
www.burrow.cs.indiana.edu
```
which is somewhat easier to type and perhaps easier to remember.
Textbooks are in the bookstore and will be put on reserve at Swain on Thursday
Brief overview of the course.
Initial server setup
CGI and Perl (server side) programming
Client side (Java and Javascript) programming
Writing and understanding servers and clients
Network protocols
Java servlets and Java RMI
Web security
Web site design considerations
Team projects
We'll also look at PHP, JSP, JDBC, SSL, XML, DHTML
This course is mostly oriented towards providing functionality (transactions) rather than just static hierarchies of documents although we will discuss those as well.
This is a programming class and you will write programs. Programs written in this class need to involve at least two computers.

Setting up Apache

The following is related to the material that starts on page 68 in what is listed at the bookstore as the required text (by Lincoln Stein).

You will need to use your own username and port number (listed on the students and projects page) to install Apache.

You need to have a burrow account (I will use dgerman)
Your machine will be www.burrow.cs.indiana.edu, just as anyone else's.
You will also be assigned a port number (I will use 10000)
You must use the port number assigned to you so please replace the underlined characters in the instructions that follow with your own username and port number.
Log into www.burrow.cs.indiana.edu machine. Then install Apache.
Here's a summary of the steps:
1. mkdir apache
2. cd apache
3. cp /u/dgerman/apache*.gz apache.tar.gz
  You would otherwise get it from http://www.apache.org in a way that will be detailed soon. This version of Apache is 1.3.1 - we will soon install a more recent version, and eventually the latest version, but to start with we install v1.3.1 (1998).
  
  For next sequence of commands explanations to be provided in the labs and lecture. It would be good and worthwhile for you to try to annotate them.
4. gunzip apache.tar.gz
5. tar xvf apache.tar
6. cd
7. mkdir httpd
8. cd httpd
9. cp -R ../apache/apache_1.3.1/* .
10. mv src/httpd-solaris26 httpd
11. cd conf
12. cp httpd.conf-dist httpd.conf
13. emacs httpd.conf
  This is the server's main configuration file. Identify the two lines that start with ServerRoot and Port, and change them to:
  ServerRoot /u/dgerman/httpd Port 10000
  You need to use your own username and the port assigned to you, so replace the information in blue with your own information. Ports will be distributed in the lab and are posted on the course web page.
  Also add a line like this
  LockFile /tmp/apache.lockfile.dgerman
  at the end of httpd.conf. Make sure it ends in your username.
14. cp srm.conf-dist srm.conf
15. emacs srm.conf
  This configuration file defines the name space for the server's users and a few other settings. Identify the lines that start with DocumentRoot and ScriptAlias and make the following changes:
```
DocumentRoot /u/dgerman/httpd/htdocs
ScriptAlias /cgi-bin/ /u/dgerman/httpd/cgi-bin/
```
  Make sure that you use your username.
16. cp access.conf-dist access.conf
17. emacs access.conf
  This file defines access-related settings. Identify those lines that contain
```
@@ServerRoot@@
```
  and make the following changes to them:
```
<Directory /u/dgerman/httpd/htdocs>
<Directory /u/dgerman/httpd/cgi-bin> 
```
  Please make sure you're using your username.
Your server is now installed, believe it or not.
You just need to start it.
cd ..
Try http://www.burrow.cs.indiana.edu:10000 now.
Make sure you use your port number.
Start the server:
./httpd -d .
Try http://www.burrow.cs.indiana.edu:10000 again now.
Make sure you use your port number.
To restart the server:
```
cd logs
kill -HUP `cat httpd.pid`
```
Make sure you notice the backquotes (`). They're special.
On my keyboard the backquote charatcer is on the same key with tilda (~) key.
This is right above the BackSpace key. On your keyboard it might be different.
To stop the server:
cd logs
kill `cat httpd.pid`

That's pretty much what we did in the first class.

Of course this was just a quick tour.

We'll go over this in greater detail in class on Thursday.
