Introduction
============

Welcome to MS4W, the quick and easy installer for setting 
up MapServer For Windows and its accompanying applications 
(e.g., Chameleon, MapLab,etc.). The purpose of this package 
is to allow novice to advanced MapServer users to quickly 
install a MapServer development environment on their 
Windows systems. The reasons for needing to do this are 
diverse but, in general, this package supports: developers 
who want to get to a stable state quickly, trainers who 
need an easily-installed configuration identical across 
multiple installs, and novices who need help just getting 
all the needed bits and pieces together.

Design
======

The MS4W package is designed to perform a full installation 
of Apache, PHP, MapServer CGI, MapScript (CSharp, Java, 
PHP, Python), and to provide the capability to install 
additional applications easily and quickly. The simplest 
way to do this on Windows is to provide a predetermined 
directory structure and force everything into that mold.

The directory structure, while fixed within itself, is 
designed to be somewhat portable. While it needs to be 
installed at the root of a hard drive, it doesn't have to 
be the C: drive. Moving the package to the root of a 
different drive is simple - just copy it there. To move it 
to a subdirectory is more difficult - you'll need to search 
for /ms4w in all the files and replace it with your new 
path.

The design also accommodates simple upgrades to the core 
package and to applications, without affecting the local 
configuration or the configuration of other installed 
applications.

Currently, the MS4W installation is considered neither 
secure nor stable. It should not be used for production 
purposes. Do not expect to get any support for using this 
package in such an environment.

   - temporary files go here. This should be cleaned 
     regularly

- ms4w/tmp/ms_tmp 
   - temporary files that need to be Web-accessible go 
     here (i.e. image files created by mapserver). This is 
     available as /ms_tmp/ via URL. Normally this means 
     that your MAP files would have an IMAGEPATH of 
     /ms4w/tmp/ms_tmp/ and a IMAGEURL of /ms_tmp/
    
- ms4w/tools 
   - contains useful tools such as the gdal/ogr utilities 
     and mapserv utilities (note that before running these 
     you must execute the /ms4w/setenv.bat script in 
     your command window)

How to Install MS4W
===================

A. Upgrading from an older version of MS4W:
-------------------------------------------

If you already have MS4W installed please do the following:
  
- open a DOS command window and execute the file 
  '/ms4w/apache-uninstall.bat' at the commandline.  This 
  file will stop and uninstall your Apache service.  You 
  should see the following message flash in the command 
  window:  

:: 

  The "Apache Web Server" service is stopping.
  The "Apache Web Server" service has stopped.
  
  Removing the "Apache Web Server" service
  The "Apache Web Server" service has been removed 
  successfully.

- your old apache service has now been removed 

- make sure no files or other services point the your ms4w 
  folder.  If your browser is currently open and you are a 
  viewing an ms4w page you will not be able to rename the 
  ms4w folder.  Therefore you must close all ms4w documents, 
  all ms4w browser windows...make sure no running files 
  point to the ms4w folder.

- rename the old ms4w folder to something like 'ms4w-old'

- extract the ms4w_xx.zip file to the root of a
  drive on your machine

- if successful, you should have a new directory named 'ms4w'
  at the root of the drive you chose (e.g. C:/ms4w or D:/ms4w ).

- follow the rest of the install instructions in 
  /ms4w/README_INSTALL.txt to start apache...


B. If you are extracting MS4W for the first time:
-------------------------------------------------


Please read through the following instructions before 
starting your installation.

1. To install the MS4W .zip file, use a compression program 
   (e.g. WinZip) to extract the package at the root of a 
   drive, e.g., drive C:\. If successful, you should have a 
   new directory named 'ms4w' at the root of the drive you 
   chose (e.g. C:/ms4w).

2. Start your MS4W Apache Web Server by running
   /ms4w/apache-install.bat (at the command line or by 
   double-clicking it). This file installs Apache as a 
   Windows service (called "Apache Web Server") so that it 
   starts whenever your machine is restarted.  When 
   executed, a DOS window should pop up with the following 
   message:
    
   ::
   
        The Apache Web Server service is starting.
        
        The Apache Web Server service was started successfully.
      
   This means that Apache is running and installed as a 
   service.
     
   **NOTE for Win95,98,ME users:**
   
   You will not be able to install Apache as a service, so 
   instead you will have to manually start Apache each time, 
   by clicking on /ms4w/Apache/bin/apache.exe.  An empty DOS 
   window will open, which means Apache is running.  To stop 
   Apache you will have to close this empty DOS window.

3. To test that Apache is running properly, open your Web 
   browser and find your local host Web service by entering 
   one of the following URLs:

   ::
   
        http://localhost/

        or

        http://127.0.0.1/

   You should now see the main MS4W page in your Web 
   browser. This gives you general information about your 
   install along with configuration information. If this is 
   your first time using MS4W it is very important that you 
   review the listed "Features" installed within MS4W, and 
   test them by selecting each link found on this page.


4. Technically, at this point, MS4W is installed! However, 
   as you may have noticed from the MS4W main index.html 
   page, there are no applications running. What this means 
   is that there are no Web applications like MapLab or 
   Chameleon found within MS4W's Web-accessible directory, 
   /ms4w/apps/. The MS4W-configured Web applications can 
   be found on http://maptools.org/ as separate zip files.

5. To install these Web application into /ms4w/apps/ all 
   that is required is to unzip the Web application 
   compressed file at the same root directory as MS4W 
   (e.g., C:\).

   Two things should happen when uncompressing this file. 
   First, the Web application directory should appear 
   within /ms4w/apps/.  Second, a new httpd_*.conf file 
   should be added to /ms4w/httpd.d/httpd_*.conf. (The 
   /httpd.d/ directory contains Apache configuration files 
   that define which files on your computer/server are 
   Web-accessible. For each Web application that you 
   install, a new configuration file will be found.)

6. The definitions of these Web-accessible directories are 
   called Web Aliases. In order to activate a Web Alias you 
   must restart Apache.  To test your latest installed 
   application, go to the MS4W main index.html page (i.e., 
   http://localhost/). In the applications section you 
   should now find a link to the application you just 
   installed. Select the link to the recently installed 
   application to see if it is configured correctly. Another 
   option is find the Web Alias for your application and 
   call it from your Web browser directly. For example, if 
   you have installed the latest MS4W version of MapLab, 
   the chances are the Web Alias is "maplab". To go to the 
   MapLab index page, simply enter http://localhost/maplab/.

   Note: Applications with configuration files (e.g., MapLab 
   and Chameleon) generally do not require any editing of 
   their files in order to work. Just unzip to the 
   appropriate driver root and restart Apache.

   WARNING: It is very possible that you may wish (but not 
   encouraged!) to run multiple versions of the same 
   product. For example, Maplab 2.0 (mapserver_36) vs. 
   MapLab 2.1 (mapserver_4.0). When installing these ms4w 
   MapLab application packages, you will notice when 
   unzipping MapLab that the httpd_maplab.conf file found 
   under ./ms4w/httpd.d/ will be overwritten by the MapLab 
   you are currently installing. The reason for this is 
   that the MapLab Alias stays the same from version to new 
   version of MapLab. So, if you overwrite the 
   httpd_maplab.conf when unzipping and then restart Apache, 
   you will get the latest version of Maplab that you just 
   installed. To run both MapLab simply follow the 
   instructions in Step 7. 
    

7. You also can create new Web Alias(es). To configure your 
   own personal Web Alias(es), follow the instructions in 
   /ms4w/httpd.d/README_HTTPD.txt
    
C. GDAL/OGR Plugins 
-------------------

MrSID
#####

For GDAL support of MrSID files, MS4W >= 1.5.0 includes 
gdal_MrSID.dll in /ms4w/gdalplugins/ignored/, which is 
built for MrSID 5.0.6.955. 


Steps to Enable MrSID Support in MS4W
*************************************

1. Download the MrSID SDK 5.0.6.955 dlls for vc7.1 
   (from http://developer.lizardtech.com/)
   and extract it on your machine (the same machine that you 
   are running MS4W on).  You'll need to create a user 
   account to download the SDK.  Look for "GeoExpress SDK 
   for Windows - vc7.1".
   
2. Add the following path to the MrSID dlls from that SDK 
   to the PATH environment variable on your machine (modify 
   the beginning of it for your exact install location):  
   
   ::  
   
     C:\Geo_DSDK-5.0.6.955\lib\Release_md

3. Move the gdal_MrSID.dll plugin file up one level from 
   /ms4w/gdalplugins/ignored/ into /ms4w/gdalplugins/
   
4. Restart Apache to be safe.

6. For mapfile configuration see 
   http://mapserver.gis.umn.edu/docs/howto/raster_data

7. Use the gdalinfo.exe utility to test if the new MrSID 
   format is available in your GDAL install now:
   
   - first make sure to run /ms4w/setenv.bat
   
   - run gdalinfo --formats
   
     ::
     
       D:\ms4w>gdalinfo --formats
       Supported Formats:
         MrSID (ro): Multi-resolution Seamless Image Database
         VRT (rw+): Virtual Raster
         GTiff (rw+): GeoTIFF
         NITF (rw+): National Imagery Transmission Format
         ...
         
Troubleshooting:

- if you are having troubles viewing a MrSID file in your web 
  browser, try adding the following in your mapfile, anywhere
  in the MAP object:
  
  ::
  
    CONFIG "GDAL_DRIVER_PATH" "C:/ms4w/gdalplugins"

Oracle 10g
##########

For OGR support of Oracle, MS4W >= 1.5.0 includes 
ogr_OCI.dll in /ms4w/gdalplugins/ignored/, which is built 
for Oracle 10g. 

Steps to Enable Oracle 10g Support in MS4W
******************************************

1. Make sure you have Oracle 10g client software installed 
   on your machine (the same machine that you are running 
   MS4W on).

2. Replace the existing libmap.dll in /ms4w/Apache/cgi-bin/ 
   with the one in the 
   /ms4w/Apache/cgi-bin/ignored-libmap/oracle10g/
   folder.

3. Move the ogr_OCI.dll plugin file up one level from 
   /ms4w/gdalplugins/ignored/ into /ms4w/gdalplugins/
   
4. Restart Apache to be safe.

5. For mapfile configuration see 
   http://mapserver.gis.umn.edu/docs/howto/oracle_spatial_howto

SDE 9.1
#######

For OGR support of ESRI's ArcSDE, MS4W >= 1.5.0 includes 
ogr_SDE.dll in /ms4w/gdalplugins/ignored/, which is built 
for ArcSDE 9.1.  

Steps to Enable SDE 9.1 Support in MS4W
***************************************

1. Make sure the ArcSDE SDK dlls for 9.1 are available on 
   your machine (the same machine that you are running MS4W on)..

2. Replace the existing libmap.dll in /ms4w/Apache/cgi-bin/ 
   with the one in the 
   /ms4w/Apache/cgi-bin/ignored-libmap/sde9.1/ folder.

3. Move the ogr_SDE.dll plugin file up one level from 
   /ms4w/gdalplugins/ignored/ into /ms4w/gdalplugins/
   
4. Restart Apache to be safe.

5. For mapfile configuration see 
   http://mapserver.gis.umn.edu/docs/reference/vector_data/arcsde

D. MapScript configuration
--------------------------

MS4W >= 1.5.0 includes pre-built support files for csharp, 
java, and python mapscript.  In order to make use of these, 
however, they must be installed and configured in the 
appropriate locations on your system.

Python
######

Obtaining Python
****************

Obviously, in order to run Python mapscript, you need to have 
a python installed.  The Python mapscript support files 
included in this distribution are built for Python 2.4.x; 
they will not work with earlier or later Python versions.  
Windows Python binaries can be obtained free of charge from 
ActiveState_ or the Python_ site.

.. _ActiveState: http://www.activestate.com/Products/ActivePython/
.. _Python: http://www.python.org

See the respective sites for Python installation information.

Installing the Python Mapscript Support Files
*********************************************

Quick and dirty (for use with ms4w only)
````````````````````````````````````````

1. Unpack ``/ms4w/Apache/mapscript/python/mapscript*win32.zip`` 
   in a safe location

2. In the directory structure that results from the above 
   step, navigate to
   ``\Python-2.4.2\Lib\site-packages``

3. You should find three files there:
     - _mapscript.pyd
     - mapscript.py
     - mapscript.pyc

4. Copy the three files into the ``/ms4w/Apache/cgi-bin`` 
   directory.

5. Place any python cgi scripts that you want to run under 
   ms4w in the ``/ms4w/Apache/cgi-bin`` directory, and add 
   a "shebang" line at the top of each script.  See the 
   section on `Configuring Apache to run Python scripts`_ 
   below for shebang-line details.

More robust (for system-wide access)
````````````````````````````````````

1. Unpack ``/ms4w/Apache/mapscript/python/mapscript*win32.zip`` 
   in a safe location

2. In the directory structure that results from the above 
   step, navigate to ``\Python-2.4.2\Lib\site-packages``

3. You should find three files there:
     - _mapscript.pyd
     - mapscript.py
     - mapscript.pyc

4. Copy the three files into the site-packages directory of 
   your Python 2.4.x installation 
   (eg., ``C:\Python24\Lib\site-packages``)

5. Add ``<drive_letter>:\ms4w\Apache\cgi-bin`` to your 
   system's PYTHONPATH environment variable.  

Configuring Apache to Run Python Scripts
****************************************

You have a couple of options here:

via shebang lines
`````````````````

This may be the preferred approach if you have multiple 
Python installations on your machine.

Add a "shebang line" to the top of each python cgi script 
in ``/ms4w/apache/cgi-bin``.  This line must be the first 
line in the script, and it must begin with #! followed by 
the path to your systems python executable.  For example: 

::

  #!c:/python24/python.exe -u

The ``-u`` option shown above causes the script to use 
unbuffered output, which is generally what you need in 
web-serving contexts.

via Apache directives
`````````````````````

This approach obviates the need to edit every python script 
in your cgi-bin directory; however, it may be problematic 
if you have multiple Python installations.

Add the following line to the end of 
``ms4w/Apache/conf/httpd.conf``: 

::

  ScriptInterpreterSource Registry

You may also want to add these: 

::

  SetEnv PYTHONUNBUFFERED 1
  PassEnv PYTHONPATH

The first of the above lines causes your python scripts to 
use unbuffered output (which you probably want), while the 
second passes the value of your system's PYTHONPATH 
environment variable through to Apache's environment 
(if set).


Testing the Configuration
*************************

Follow these steps to test your Python MapScript
installation:

1. Move the file ``/ms4w/python/test-cgi-mapscript.py``
   into the ``/ms4w/Apache/cgi-bin/`` folder.

2. Open the file in a text editor.
   
3. Edit the first line of that script to point to your
   proper Python path.
   
4. In your web browser goto http://127.0.0.1/cgi-bin/test-cgi-mapscript.py

5. The script tests that the Python CGI is working, and
   that the mapscript module can be successfully imported.
   
   If successful you will see an HTML page listing several
   environment settings on your machine, as well a list of 
   the Python MapScript module attributes at the bottom
   of the page.
   
Python Troubleshooting:

- If you get an Internal Server Error check the Apache logs 
  for info.
  
- Make sure your script points to a valid Python installation
  path.
  
- Make sure you are using a recent Python version
  (containing the cgitb module).

D. Troubleshooting 
------------------

**Warning: dl(): Unable to load dynamic library 
'/ms4w/Apache/php/extensions/php_mapscript_48.dll'**

1. Verify that the dll in question exists in the 
   specified location (/ms4w/Apache/php/extensions/).  If 
   this dll is not in that location, you might have to 
   modify the application to point to a different version of 
   the dll (e.g. you might have *php_mapscript_48.dll* in 
   the extensions directory, and your application might be 
   configured for *php_mapscript_46.dll* which is not in the 
   extensions directory).
   
2. This php_mapscript dll requires several other dlls, and 
   the problem may be that one is missing on your system.  
   In order to hopefully get more information on what dll 
   is missing, go to a command prompt, and do the following:
   
   ::

     cd ms4w\Apache\cgi-bin
   
     php C:/ms4w/Apache/htdocs/phpinfo_mapscript_**.php  
   
   (replace ** with the mapscript version)
   
   A windows error window should open with a message like:
   
   ::
   
      The dynamic link library ***** could not be found in 
      the specified path...
      
   Locate this missing dll and copy it either to 
   /ms4w/Apache/cgi-bin/ or your system32 folder.
   
3. If you are still unsure what dll is causing this *unable 
   to load dynamic library* error, a useful utility to find 
   what associated dlls are missing on your system is 
   `Dependency Walker`_.  Download the utility, execute the 
   exe, and open your php_mapscript dll.
   
.. _`Dependency Walker`: http://www.dependencywalker.com/  

**The dynamic link library MSVCP71.dll could not be found 
in the specified path...**

This is a microsoft runtime library that is apparently not 
on all Windows systems by default.  Download the dll 
(possibly from `here`_) and copy it to your System32 
directory.

.. _`here`: http://www.dll-files.com/dllindex/dll-files.shtml?msvcp71

**Clicking on apache-install.bat flashes a DOS window and 
does not install the service**

To see the exact error message, open a Command window, and 
execute the 'apache-install.bat' file from a DOS prompt.

::

  cd ms4w
  
  apache-install.bat
  
**Only one usage of each socket address (protocol/network 
address/port) is normally permitted.  : make_sock: could not 
bind to address 0.0.0.0:80 no listening sockets available, 
shutting down**

Apache with MS4W is configured to use port 80.  Your system 
might be already using this port (IIS could cause this for 
example).  If you want to change the port that Apache uses 
modify the following file:

::

  /ms4w/Apache/conf/httpd.conf
  
  line 120: Listen 80
  
`TCPView`_ is an example of shareware that lets you see 
how the ports on your machine are being used.

**The procedure entry point xxxx could not be located in the 
dynamic link library xxx.dll**
   
Make sure that MapServer (or the utility that you are trying 
to use) is actually using the 'xxx.dll' file that is part 
of the MS4W package.  You could be experiencing 'dll hell' 
(http://en.wikipedia.org/wiki/DLL_hell) where MS4W is 
actually finding an older dll on your system.  Try renaming 
the other dll(s) of the same name, keeping the one in MS4W 
as is, and retrying your application/command.

**Other Problems...**

1. Search the `mailing list archives`_ to see if someone has 
   encountered/solved your same issue.

.. _`mailing list archives`: http://lists.maptools.org/search.phtml?config=ms4w-users 

2. If your issue has not been brought up on the mailing list 
   and dealt with, submit a question to the 
   `MS4W mailing list`_.  Include the steps to reproduce 
   your problem, and state your exact error message.  Also 
   specify which version of MS4W you are using.

Password Protection Configuration for Applications
==================================================

The following section explains how to add password 
authentication to your MS4W application.  However there are 
many other possible settings in Apache for this, so please 
consult the Apache HTTP Server documentation.

Here are the minimal step for password protection:

1. Modify your application's httpd_xxx.conf file, so that 
   "AllowOverride None" is replaced with "AllowOverride 
   AuthConfig", such as:
   
   ::
   
     Alias /gmap/ "/ms4w/apps/gmap/htdocs/"
     
     <Directory "/ms4w/apps/gmap/htdocs/">
       AllowOverride AuthConfig
       Options Indexes FollowSymLinks Multiviews 
     </Directory>
     
2. Create a password file.  

   - open a DOS command window, and go to Apache's bin 
     directory
   
   - enter the following (replace "jeff" with the username 
     you want to create, press ENTER and you will be 
     prompted for a password to create):
   
     ::
   
       C:/ms4w/Apache/bin> htpasswd -c htpasswd.txt jeff
      
3. Create the htaccess file.  

   - create a file in your application directory 
     (/ms4w/apps/gmap/htdocs/ in this example) named 
     '.htaccess'
     
   - the file should contain (you can modify it however you 
     wish though):
   
     ::
     
       AuthType Basic
       AuthUserFile C:/ms4w/Apache/bin/htpasswd.txt
       AuthName "Password Required"
       
       require valid-user
 
4. Restart Apache

   - run /ms4w/apache-restart.bat
   
5. Access your application in a web browser.

*Troubleshooting:*

- some Windows versions may have difficulty with the 
  '.htaccess' filename, so you might try naming it something 
  else, but you would have to modify Apache's httpd.conf 
  file (/ms4w/Apache/conf/httpd.conf) and add your filename, 
  such as:
  
  ::
  
    AccessFileName .htaccess yourfilename
    
  'htaccess.acl' is recommended, such as:
  
  ::
  
    AccessFileName .htaccess htaccess.acl
