These are the notes for Tue Jun 30 started at 15:33:59 EDT 2009

Lecture goals for today: 

a) finish installing PHP
b) set up password protected folder
c) post Homework One 

Last time we installed MySQL and we started installing PHP. 

Start by going into

  cd /nobackup/dgerman/php-5.1.4

Yesterday we created a file step005 and we run it. 

Page 51 in http://www.cs.indiana.edu/~dgerman/eowp06.pdf has the instructions.

Next create a file (and call it step006) with this content:

  make
  make install

Then make the file executable and run it. 

We wait... maybe 10-12 minutes. 

Meanwhile why don't we set up the protected folder. 

The instructions are in the text chapter 6 pp. 33-34. 

a) first create a protected folder in htdocs
the name should be: protected and it's in htdocs

   mkdir ~/apache/htdocs/protected

b) set up a file (named passwd) with usernames and passwords
you need to use a special utility to do that
the utility is delivered with apache, so you have it 
but I would like to have the same password (and username) to access all websites
but you should not know my password 
so I should give you my encrypted password

one way would be for you to create with pico ~/apache/passwd
then add this as the first line: 

dgerman:UIaTPpE.ZpwHw

then exit and save the file

another way would be to copy /u/dgerman/public/passwd in ~/apache/passwd

 cp /u/dgerman/public/passwd ~/apache/passwd

So either way it's fine. Now you have the right starting point for this file.

Now you need to start using ~/apache/bin/htpasswd to add users. 

I run this command: 

-bash-3.2$ ~/apache/bin/htpasswd -b ~/apache/passwd lbird dribl 
Adding password for user lbird

The file now becomes: 

-bash-3.2$ cat ~/apache/passwd
dgerman:UIaTPpE.ZpwHw
lbird:13rXCyijE6/QE
-bash-3.2$ 

Then take this code:

<Directory /u/[username]/apache/htdocs/protected>
  AuthName Protected
  AuthType Basic
  AuthUserFile /u/[username]/apache/passwd
  <Limit GET POST>
    require user [instructor]
    require user [username]
  </Limit>
</Directory>

Then open the file:

  pico -w ~/apache/conf/httpd.conf

And go to line 125 or so (^W, ^T, 125).

For me it looks like this: 

# you might expect, make sure that you have specifically enabled it
# below.
#
   <-----------(line 125)     
#
# This should be changed to whatever you set DocumentRoot to.
#

Copy the code there.

Change the [username] into your username.

Change [instructor] into dgerman. 

Save and exit. 

Check that the file is still having good syntax: 

-bash-3.2$ ~/apache/bin/apachectl configtest
Syntax OK
-bash-3.2$

Now go to protected and create some files there. 

pico ~/apache/htdocs/protected/homeworkOne.txt

Type something in it, save and exit. 

Then

pico ~/apache/htdocs/protected/homeworkTwo.txt

Type something in it, save and exit. 

And now restart the server, then access protected: 

 ~/apache/bin/apachectl restart

Protected is available from:

 http://silo.cs.indiana.edu:44xxx/protected

Now let's go back to finishing the PHP installation. 

Copy php.ini-dist from /nobackup/username/php-5.1.4 to 
~/apache/conf/php.ini (changing its name in the process): 

 cp php.ini-dist ~/apache/conf/php.in

Then go to 

-bash-3.2$ cd ~/apache/conf
-bash-3.2$ ls -ld php.ini 
-rw-r--r-- 1 dgerman faculty 41989 Jun 30 16:42 php.ini
-bash-3.2$ pico php.ini

Change the file: 

a) turn line 892 into 

   session.save_path = "/u/username/apache/phpsessions" 

b) turn line 399 into 

   register_globals = On 

Then exit and save. 

Open ~/apache/conf/httpd.conf

Go to line 304 (or so) and paste these two lines:

AddType application/x-httpd-php .php .phtml
AddType application/x-httpd-php-source .phps

That comes for me after

    #
    #AddType application/x-gzip .tgz

Now exit, save, stop the server 

-bash-3.2$ ~/apache/bin/apachectl stop

and start the server.

-bash-3.2$ ~/apache/bin/apachectl start

Your PHP is installed, we just have to demonstrate it. 

Create a file called one.php in ~/apache/htdocs:

  pico ~/apache/htdocs/one.php

The contents is:

  <? phpinfo(); ?>

Save, exit then call this from a browser: 

  http://silo.cs.indiana.edu:44xxx/one.php

The result is a lot of output with your PHP settings.
